Description

DESCRIPTION VERTICAL TURBO CRUSHER

Related Field of Invention: This present invention related to vertical turbo crusher designed for crushing of every kind of material to be size reduced, mainly stone, ore, sand, medical material, grain etc.

Background of the Invention (Prior Art):

Size reduction by crushing of material is well known and there are many type of machines and processes existing. Crushing is vital part of many field of industry.

Related to present invention developed said Vertical Turbo Crusher; basics of crushing applications are described below.

As many types of crushers are in practice, they may be summarized in two main groups. • Impact crushers; this type of crushers are designed as crushing of material by the effect of impact. Main types of this category of crushers are; horizontal shaft impact bar, horizontal shaft hammer, vertical mill impact crushers.

• Compression effective crushers; this type of crushers make size reduction by compression applied on material. Most typical crusher of this group is conical crusher. • Jaw crusher which is combination of compression and impact crushers are widely used too.

IMPACT CRUSHERS

Impact crushers generally operate with principle of utilizing rotational movement of crushing components which transfers power to material to be crushed. Crushing power exerted to material in different ways. Brief description of impact crushers are as follow.

• Hammer crusher; Material goes under size reduction by Impact of hammers (19) installed on rotor (18). Than pass through a grate (20) of which gap between grate bars adjusted. Finally leaves the crusher as size reduced In fig 8 hammer type of crusher is shown. • Impact bar crusher; Material goes under size reduction by Impact of impact bars (22) installed on rotor (21). Than pass through a passage between impact bars and impact wall (23) as size reduced

In fig 9 hammer type of crusher is shown. • Vertical shaft impact crusher; Material fed from top into crusher rotor (24) which turns with high speed around vertical axis, than accelerates horizontally and thrown by centrifugal force to stationary material bed (25). First size reduction occur at the maximum speed point by hitting of tool bit (26) fastened to rotor, later another size reduction done by impact on material bed and dropped material get out of crusher. Very high speed necessary since hitting on material is not by the impact of crushing component. Depending on high speed and heavy wear of components tool bits are manufactured from superior material like tungsten carbide which is very costly.

In fig 10 hammer type of crusher is shown.

By impact crushing material gets mostly regular prismatic form and if it is preferred for the end using, impact crushers preferred too.

As noted for all impact crushers, components like hammer, impact bar, tool bit are necessary. Components like grate, impact wall, material bed installed against working of impact components complete the system. Impact components wear out in time. In the same way stationary components like grate, impact wall wear out too. As the result of this wearing, efficiency of impact components decrease, the working gaps between rotational and stationary components increase and overall crushing efficiency of the equipment decreases. Especially wearing of crushing components reduces the efficiency of crushing process considerably after certain point and it becomes necessary to replace worn out components. Worn sections of crushing components compose few portion of component mass. Since the whole component to be replaced, components manufactured from special material bring considerably cost.

Another weak point of impact crushers are eventual breakdowns which are the result of continuous impact effect on equipment. Realization of such risk brings considerably production lost and repair costs. COMPRESSION EFFECTIVE CRUSHERS

This type of crushers makes size reduction by applying compressive pressure on material. Basic principle is to get the material in crushing chamber which narrows gradually.

As material compressed in this gradually narrowed geometry at the same time additional compression applied by a hydraulic system. Operation of this type of crushers described below.

• Conical crusher: Material fed to crushing chamber between rotor (27) and stationary housing (28) and goes downwards in gradually narrowed cross section. Rotor (38) rotates eccentrically with respect to vertical housing axis and makes narrowing of cross section in horizontal plane. Hydraulic system (29) pressure applied on rotor and the gap between rotor and housing decreases. Hence hydraulic compressive force exerted on material to be crushed. Material compressed both by mechanical and hydraulic forces get out from bottom of crusher.

In fig 11 conical crusher is shown. • Jaw crusher: Compressive pressure and impact effect both applied at the same time on material dropping through gradually narrowed gap between eccentrically driven and elliptically reciprocated mobile jaw (30) and stationary jaw (32). Size reduced material get out from bottom of crusher.

In fig 12 jaw crusher is shown. Compression effective crushers consume less power for the same operation compared to impact crushers. On the other hand crushed material is not regularly prismatic, rather having less prismatic shape formed by decomposition of material from its natural breaking planes and lines. Compression type crushers are widely used, if this prismatic property is not required by the process or if this property is not definitive at that stage of size reduction.

Wearing of components is an important factor in compression type crushers since moving and stationary components are always in contact with material and an additional pressure occurs on these components by hydraulic system. Working gap increases because of wearing of crushing components and efficiency of crusher decreases considerably. After certain point it becomes necessary to replace worn components. Worn sections of crushing components compose few portion of component mass. Since the whole component to be replaced, components manufactured from special material bring considerable cost. Rotating components under hydraulic pressure sometimes go under high impact effect. This impacts ends with equipment breakdown resulting considerable production loss and high repair cost.

Aims of the Invention:

There are many types of crushers for crushing, having many different process type and equipment design of existing technique today, as explained before. Two main process types are to crush either by impact or by compression effect.

Comparison of the Invention with the existing technique:

Comparison of Vertical Turbo Crusher developed by this invention with applications of existing technique described is as follow.

COMPARISON WITH IMPACT CRUSHERS

Crushing action in Vertical Turbo Crusher is done by rotating housing of machine which was designed as a crusher rotor. Hammers on rotating housing hit to material spreading around and very effective crushing process achieved by this way. Impact on material spreading by centrifugal force coupled ^"by impact coming from opposite direction and crushing effect on material multiplied.

Considering horizontal shaft impact crushers, manufacturing of rotors on which crushing components (hammers) fastened requires considerable accuracy and cost. Especially fixing way of crushing components (hammers) to rotors should be such to withstand impacts occurred. Design of rotors in Vertical Turbo Crusher is simpler. Considering horizontal shaft impact crushers, the flywheel, mostly drive pulley at the same time has fixed mass. To increase the mass brings undesired load on shaft bearings. Changing of flywheel mass could be done easily in on Vertical Turbo Crusher and this possibility brings important characteristics to crusher. Many process selections achieved together with speed adjusting drive system. Considering wear dynamics of crushing components and grates, it is not possible for the Vertical Turbo Crusher to become useless after certain point, because of increasing gaps. It is not possible to close working gaps resulting from wearing of crushing components in impact crushers, because of fixing way of hammers and impact bars to rotors. It is possible to move hammers forward hence to use longer time in Vertical Turbo Crusher. Vertical Turbo Crusher has more capacity to damp impacts because of its design. Changeable and adjustable mass of inner and outer rotors bring important advantage in this aspect.

Dynamic forces applied on rotor by material spreading with high rotational speed are considerably effective in vertical shaft impact crusher. Since the power is given to rotor, increasing inertia increases operational cost but does not change throwing dynamics of material. Increasing of rotor size and increasing of flywheel inertia don't help to process. The speed is the same eventually. Vertical Shaft Impact crushers can not be used as primer crushers to crush heavy and voluminous material blocks because of these restrictions. They can be used only as secondary and tertiary crusher. Dynamic effects above mentioned bring restrictions to rotor size too. Rotor speeds in Vertical Turbo Crusher are dropped to conventional crusher speeds hence dynamic effects are considerably decreased on inner rotor of vertical Turbo Crusher with inner rotor. Main crushing action is hitting of outer rotor hammers to thrown material from inner crusher. By this way speed of inner crusher reduced and size restriction of material to be crushed overcame. Considering these characteristics, it is possible to use Vertical Turbo Crusher as primary crusher. This characteristic is more evident in Vertical Turbo Crusher with anvil.

High quality components are necessary to withstand heavy wear at throwing end points of vertical shaft impact crusher because of high speeds. Special materials like tungsten carbide used for these tool bits which bring higher cost to operation. Since conventional speeds are achieved in Vertical Turbo Crusher, widely used type wear parts of this field used and costs dropped considerably.

Vertical turbo crusher with more than one stage could make the operation of one conventional plant in one place. Otherwise one crusher and conveying equipment necessary for each stage conventionally.

Manufacturing of housing does not bring additional cost since it is the crusher rotor at the same time. Unique structure of hosing and rotor is brings important advantage for the cost.

COPMARISON WITH COMPRESSION EFFECT CRUSHERS

In crushers with compression effect wearing of moving and fixed crushing components raises working gap and reduces the efficiency of whole crusher. It is necessary to replace these components after certain point. Considering wear dynamics of crushing components and considering keeping of original working gap by adjustable crushing components, it is not possible for the crusher to become useless because of gaps after certain point

Considering size and process possibilities, compression effective crushers could not be used as primary crusher. Only jaw crushers are used in this field as they are economical. Vertical turbo crusher could be used as primary crusher as other impact crushers having rotor.

There is no need of hydraulic system for compression in Vertical Turbo Crusher which brings considerable cost advantage. End product of Vertical Turbo Crusher is prismatic due to impact crushing. It is not possible to get such product with compression effective crushers.

Vertical Turbo Crusher developed by this invention as the result of

• investigation

• studying of process possibilities • establishing of weak points

• establishing of alternative solution searching according to these weak points of existing crushers, especially of hammer, impact, cone, vertical shaft impact, crushers etc.

Factors determining crushing process arising as;

• Crushing action by impact.

• Particle size distribution of material at inlet and outlet of crusher.

• Power consumption and wear.

Main components of the Vertical Turbo Crusher developed by this invention are;

• Inner rotor (1) comprising; inner rotor hammer (3), inner rotor hammer wedge

(34), Stop screw of inner rotor hammer wedge (35), Stop screw of inner rotor hammer (36), Inner rotor hammer back (32), Inner rotor drive pulley (5), Inner rotor drive unit (7), Inner rotor upper bearing (9), inner rotor lower bearing (10) and inner rotor flywheel (13),

• Outer rotor (2) comprising; Outer rotor hammer (4), stop screw of outer rotor hammer (37), outer rotor hammer back (33), outer rotor drive pulley (6), outer rotor drive unit (8), outer rotor upper bearing (11), outer rotor lower bearing (12) and outer rotor flywheel (14), • Carrying structure (15)

• Anvil (16) comprising; anvil slices (38) ,anvil hub (39), anvil block wedge (40), stop screw of anvil block (41), Stop screw of anvil block wedge (42) and anvil block (17) This invention has two versions. First version has inner rotor (1) while there is an stationary anvil (16) in second version. These versions are described in separate sections.

Vertical Turbo Crusher with inner rotor Material to be crushed dropped on center of rotating inner rotor which is forced by a drive unit (7). At this point it spreads to periphery by centrifugal force. As material accelerates till end of inner rotor (1), it hits to outer rotor (2) which rotates in reverse direction to inner rotor (1). Size reduction done by impact of inner rotor hammers (3) and outer rotor hammers (4). Material having smaller granule size dropped through the gap between inner rotor (1) and outer rotor (2). Crushing action completed this way.

Material leaving crusher is getting out by proper conveying system.

Inner rotor (1) is driven from bottom side by inner rotor drive pulley (5). Inner rotor upper bearing (9) and inner rotor lower bearing (10) support the inner rotor (1). Bearings (9, 10) could be of sliding bearing or roller bearing type. Weight of rotor is carried by carrying structure (15). This carrying structure (15) carries all components of Vertical Turbo Crusher at the same time. It is possible to get inertia as required by making adjustments on inner rotor drive pulley (5), inner rotor flywheel (13) and inner rotor (1) itself. Inner rotor flywheel has property of changing inertia by adding or removing mass. One of the important weaknesses of conventional vertical shaft impact crushers is not producing mass inertia for flywheel effect. Rotor speed could be decreased according to inertia achieved. Inner rotor drive pulley (5) could be installed under bearings or between bearings as well.

Crushing action is done by inner rotor hammers (3) installed on inner rotor (1). These inner rotor hammers (3) are installed in proper recesses. Inner rotor hammers (3) are supported by inner rotor backs (32) on reverse side of impact point. By this way it is possible to slide out worn inner rotor hammers (3) under control in time. Utilizing most portion of inner rotor hammers (3) reduces operating cost considerably.

Inner rotor hammers (3) are fixed on inner rotor backs (32) by inner rotor hammer wedge (34). Inner rotors hammers (3) and inner rotor hammer wedges (34) pressing out by centrifugal force, block each other and become rigid on conical faces narrowing from center to periphery. Inner rotor hammers (3) worn in time are slides out by using stop screw of inner rotor hammer (36). To do this, inner rotor hammer wedge (34) slides by stop screw of inner rotor hammer wedge (35). By this way positions of inner rotor hammer (3) and position of inner rotor hammer wedge (34) do not change according to each other. Inner rotor hammers (3) could not escape upwards from inner rotor hammer backs (32) as they have conical shape avoiding upward motion.

Inner rotor (1) could have one stage or multiple stages depending on purpose of utilization. Closed type inner rotor (1) is used for highly abrasive material as done in conventional vertical shaft impact crushers

Outer rotor (2) is actually complete body itself and driven by a separate outer rotor drive pulley (6) which is rotated by outer rotor drive unit (8). Direction of rotation is opposite to direction of rotation of inner rotor (1). Outer rotor upper and lower bearings (11, 12) support the outer rotor (2). These bearings (11, 12) could and sliding or roller type. Carrying structure (15) carries the outer rotor (29) via bearings. Required inertia is build by addition of outer rotor flywheel (14). Pulley drive could be on upper side of bearings or could be between bearings.

Crushing action is done by outer rotor hammers (4) which are installed at inner side of outer rotor (2). These outer rotor hammers (4) are properly installed in recesses. Outer rotor hammers (4) are supported by outer rotor hammer backs (33) on reverse direction of impact point. By this way it is possible to slide worn outer rotor hammers (4) under control in time. Utilizing most portions of outer rotor hammers (4) reduces operating cost considerably. Depending on wear, outer rotor hammers (4) slide towards inside of outer rotor (2) by stop screws of outer rotor hammer (37). Outer rotor hammers (3) could not escape upwards from outer rotor hammer backs (33) as they have conical shape avoiding upward motion.

Outer rotor could have one stage or multiple stages depending on purpose of utilization.

Crushing operation is most effective when coarse material subjected to impact between crushing components of inner rotor (1) and outer rotor (2). At this point momentum of both rotors transferred to material to be crushed.

Since inertia of rotors could be adjusted as required as possible, this brings design property to Vertical Turbo Crusher which is not possible for horizontal shaft impact crushers.

It is possible to reduce rotor speeds to speeds of conventional horizontal shaft impact crushers depending on this design advantage. In this design main impact is done by outer rotor (2) with possibility of having more inertia. Inner rotor (1) rotates with enough speed to throw material out and main impact is done by outer rotor (2).

Material size passing through the crusher is being obtained by the gap between rotors. Rotors are designed as staged for higher size reduction ratios. Starting from uppermost stage the gaps between rotors are reduced progressively. Vertical turbo crusher with 3 stages of inner rotor (1) shown in fig. 5

VERTICAL TURBO CRUSHER WITH ANVIL

Inner rotor (1) is removed and a stationary anvil (16) installed instead, in vertical turbo crusher with anvil. Anvil (16) basically composed of a stationary anvil hub (39) and anvil slices (38). Anvil hub (39) fixes anvil slices (38) by its cornered shape. It makes possible also easy removing of anvil slices (38) for maintenance, repair or for any other operation. Anvil hub cross section could be cornered or could be round with key. Holes of anvil slices (38) opened according to anvil hub. Upper center of anvil hub is elevated to divert the material flow towards periphery. Material as slides towards periphery on sloped faces subjected to impact by outer rotor hammers (4) of outer rotor (2). There are anvil blocks (17) on which the material are crushed to increase the impact effect of outer rotor hammers (4). Material to be crushed is size reduced by impact of outer rotor hammers (4) on these anvil blocks (17) which are evenly installed on periphery of anvil (16). Anvil blocks (17) are designed replaceable as worn out. Most of the mass of anvil blocks (17) are used since they are stationary. Material size reduced as smaller than the gap between anvil (16) and outer rotor (2) leave crusher from bottom.

Anvil blocks (17) are fixed on anvil (16) by anvil block wedge (40). Anvil blocks (17) worn in time slide out by using stop screw of anvil block (41). To do this stop screw of anvil block wedge (42) and anvil block wedge (40) slides too. By this way positions anvil block (17) and position of anvil block wedge (40) do not change according to each other. Anvil blocks (17) could not escape upwards from anvil slices (18) as they have conical shape avoiding upward motion.

Outer rotor (2) is actually complete body itself and driven by a separate outer rotor drive pulley (6) as described in vertical turbo crusher with inner rotor (1). Rotating motion is on bearing systems (11, 12). These bearings (11, 12) could and sliding or roller type.

Carrying structure (15) carries the outer rotor (2) via bearings (11, 12). Required inertia is build by addition of mass on outer rotor flywheel (14). Pulley drive (6) could be on upper side of bearings (11, 12) or could be between bearings (11, 12).

Crushing action is done by outer rotor hammers (4) which are installed at inner side of outer rotor (2). These outer rotor hammers (4) are properly installed in recesses. Outer rotor hammers (4) are supported by outer rotor hammer backs (33) on reverse side of impact point. By this way it is possible to slide worn outer rotor hammers (4) under control in time. Utilizing most portions of outer rotor hammers (4) reduces operating cost considerably.

Depending on wear, outer rotor hammers (4) slides towards inside of outer rotor (2) by stop screws of outer rotor hammer (37). Outer rotor hammers (3) could not escape upwards from outer rotor hammer backs (33) as they have conical shape avoiding upward motion.

Crushing operation is most effective when corpse material subjected to impact between anvil blocks (17) and outer rotor (2) hammers (4). At this point momentum outer rotor transferred to material to be crushed.

Material size passing through crusher obtained by the gap between outer rotor (2) and anvil (16). Gap between anvil (16) and outer rotor (2) designed as staged for higher reduction ratios. Succeeding gaps between anvil (16) and outer rotor (2) are narrowed progressively after the first gap of uppermost stage. Vertical turbo crusher with 3 stages of anvil (16) shown in fig. 7

Anvil block (17) could be one staged or multiple staged depending on material to be In case of staged anvil block (16), each stage divided to separate anvil slice (38) Basic characteristics of Vertical Turbo Crusher;

Most of dynamic effects arising from uneven spreading of material are get rid off by decreasing the speed of inner rotor (1). Possibility for crushing of coarse material achieved.

Vertical turbo crusher could be used as primary crusher because of these characteristics.

Considering special structure of rotors, fixing details of hammers to rotors, massive flywheels carried at shaft ends of horizontal shaft crushers and considering mechanical effects of all these factors, vertical turbo crusher does all these functions with more simple mechanical design. Required actions of correction and intervention are much easier during operation.

Capacity problem can be overcame by solving size and speed problems. It is possible to reach very high outputs by simple rotor designs.
