Description

CONICAL ROTATING MILLING AND SHREDDING APPARATUS DESCRIPTIVE HEMORIA The invention relates to a rotary or conical milling and crushing apparatus of simplified construction and greater operational efficiency than grinders currently available. In the past several types of machines have been provided for grinding and grinding operations. Conventional drum mills are notoriously energy inefficient for grinding and crushing operations, and drum milling is primarily achieved by impact, which is most effective only at the base of the -t mbor bed. Recently introduced roller presses are intensive to wear due to the relative movement between the supply material, ie, the material to be ground, and the rotating surface of the rollers.Mills are usually used with vertical rollers to dry-grind minerals more soft (low abrasion) and sometimes not desired due to its considerable vertical height.Wide diameter, short length, autogenous or sein -autógenos mills, another version of the drum mills, are not usually able to grind round material Critical size conventional conical crushers have been used to crush the critical size material as an addition to the circuit of autogenous or serm-autogenous mill, complicating the maintenance requirements of the (luxury and equipment) diagram. In general, grinding based on the application of "compression" loading, such as roller, jaw crusher, rotating and rotary crushers, is more energy efficient, particularly when the relative movement between the material of the material can be avoided or minimized. supply and the load application surfaces of the device. Thus, there is a need for a rotating, efficient milling and grinding energy apparatus that maintains the simplicity of the flowchart without involving an additional shredder. to crushing critical size, and grinding materials by means of compression forces. The present invention relates to a grinder-shredder that includes a main support member and a conical bowl supported on the main support member. A comatose head is used with the grinder and includes a load application surface having an upper and lower end. The head receives a flexible seal adjacent to the lower end. The present invention also relates to a spinning mill including a main frame, a bowl support on the main frame, a rotating head and a sealing means. The bowl has an upper end and a lower end, and the head has an upper end and a lower closure. The head and the bowl define a grinding-crushing cavity. The half-elonator inhibits the material exiting the former lower oar from the milling-crust cavity. One aspect of this invention is to provide a co-rotating milling and crushing unit, for certain types of milling and crushing applications, which utilizes energy efficient compression crushing, and largely avoids movement. relative between the material being milled and the walls of the milling and trimming unit. Or, or aspect of the invention is to provide a rotating, grinding and grinding apparition having grille discharge outlets in the lower portion of the chimney or internal grinding member for the discharge of fine or ground material into form of suspension of the reinforcement cavity-t ruration. Still another aspect of this invention is to provide a combustion, rotating and grinding apparatus in which the entrusting mill can be made without any means of grinding, that is, autogenous mode, or with the aid of such a medium. Coarse mineral / flint or steel or ceramic balls. Another aspect of this invention is to provide a grinder-shredder, suitable for certain milling operations, which has improved operational efficiencies, particularly with respect to energy use and operation maintenance costs. In accordance with this invention, a grinder-crusher is provided where the grinding is essentially achieved against the sources of compression and destruction and on-demand, with very minimal relative movement between the material! grinding and crusher-grinder surfaces, Also, there is no accumulation of critical material. Unlike a conventional or conventional shredder, the internal grinding member or chimney drum has grill discharge outlets in its lower portion for discharging ground material in suspension form from the grinding cavity. In a second embodiment of the invention, discharge of milled f-inos from the grinder-crusher is achieved by air flow upwards to tr-birds (ie the grinding and discharge cavity of the top of the grinder - grinder, instead of slurry flow through chimney decarburizing outlets in the chimney The internal grinding-crushing member is rotated or wobbled within a limb member Lenda-t external downward extension shutter The tumbling mechanism is driven by a vertical rotating shaft, the material that flows down between the members (grinding or internal or external grooving in the cavity is ground or crushed between them). of limbs, a lower one that is rotated by the vertical rotating shaft driven, and an upper one that is supported for rotation on the lower one by a support assembly. This is in a plane that is not perpendicular to the axis of the vertical arrow. In this way, the upper member, the lower surface of which rests on the upper surface of the inner member, and which is prevented from rotating, will wobble as the lower member rotates. The rotation of the lower member is avoided by a first generally cylindrical bellows assembly, one end of which is indirectly secured to a fixed part of the grinder-triurator, and the other end of which is indirectly secured to the upper member. The Leo tamba mechanism, and therefore the internal grinding-ripping member, is supported to be able to adjust vertically with respect to the base of the grinder.

By adjusting the vertical position of the inferred grinding member, its position with respect to the grinding member is adjusted externally, to increase or decrease the average width of the grinding space between the members of internal grinding-tpt uration. and external. In a preferred embodiment, the vertical adjustment is provided by an air bellows assembly. By regulating the air pressure in the air fuel, the relative height of the wobble mechanism can be adjusted with respect to the base of the grinder-grinder. The eccentric reach of the internal grinding-ing member and the rotating speed of the wobble drive mechanism are chosen to promote trituration of the inner-bed or bed. A second bellows assembly closes the bottom of the mold cavity end-grinding, so that the material can not be discharged through the bottom of the cavity. The second assembly (bellows is formed of concentric rubber bellows segments of larger diameter and union rings, the larger diameter end of which is leakage to the lower end (the outer limb member) where the support wall is shown, and the bellows segment of small diameter of which is attached to the lower edge of the grinding member - internal rotating - A deflector - of ground material or suspension guide, may be in the The shape of a reed trunk The deflector of ground material or suspension serves to direct the slurry containing fines or ground material that flows through the grate discharge outlets in the internal sniffing member away from the anti- functioning bellows. - rotating thus providing abrasive damage protection by the suspension In an alternative embodiment of the invention, no grills are provided in the internal grinding member. a deflector (je ground material. Instead, an air distribution ring is provided to supply nozzles or nozzles located at the bottom of the milling-capturing cavity. The flow of air through the nozzles provides an air current that raises and carries the fines and ground material to discharge from the top-of the milling-processing cavity into an outlet channel. Accordingly, a first embodiment of the present invention involves a grinder-grinder comprising a main support member, a solid bowl having an upper end and a lower end, the lower end of the bowl resting on the member. of main support, the head has a surface of internal crust, a head that has an upper end and a lower end, the head is placed inside the bowl, the head comea that has a grinding surface, the outer surface, the outer surface of the bowl, and the outer surface of the bowl as it is separated from the surface of the inner surface of the bowl. to form a depressed cavity between them, a wobble assembly that supports the lower end of the head comes to rotate with respect to the bowl, an adjustable support to support the assembly, and wobbles over the member. or of main support, the adjustable support being adjustable to adjust the space between the external surface of the head of the head and the internal grinding surface of the bowl that forms the grinding cavity. - 1 p tur c ion, a cover on the upper end of the bowl, a first opening in the cover to introduce material to be ground in the grinding cavity-t encturac on, and a flexible seal secured L bowl When the head comes to rest adjacent to the lower ends, it prevents the discharge of material from the grinding-crushing cavity between the outer ends, the grinding-tpuration cavity being provided with a discharge opening., to tr-poultry from which the ground material is discharged from the mold cavity.
