Abstract
The utility model relates to the field of mineral industries and particularly relates to a combined screening and separating device. Extrusion scattering formed by an extruding and grinding process system and a high-pressure roller mill can eliminate adverse factors; materials which are not effectively extruded, and do not have obviously-improved granularity and grindability are returned back to the high-pressure roller mill to be extruded again, so that more powder is grinded and moved outside a mill to be loaded by a high-efficiency extruding and scattering loop; the granularity and the grindability of the grinded materials can be improved obviously. After the modification, an extruding combined powder grinding system composed of the high-pressure roller mill, a combined screening machine and a ball grinding system can increase the yield of a ball grinding system by 100%-200%; the power can be saved by more than 30% and the consumption of a grinding body is reduced by more than 60%.
Description
Technical field
The present invention relates to mining industry field, relate in particular to and combine screening and separator.
Background technology
Because high-pressure roller mill operational procedure regulation: when device start, hydraulic system should be in depressurization phase.So, in high-pressure roller mill start-up course, pass through high-pressure roller mill by having in a large number without the material of effectively extruding.This is also that the pre-grinding process system throughput of extruding increase rate before three river flowings from Guizhou Province through Hunan into Dongting Lake associatings screening machines are got involved extruding grinding process systems is little and have a major reason of larger fluctuation.
Because high-pressure roller mill has the tendency of selective pulverizing when the pressing materials; so still have the material not pushed on a small quantity in the material cake producing after extruding; in addition the intrinsic grinding roller edge of high-pressure roller mill leaks the drawback of material and the large granular materials not being adequately compressed that produces because of startup-shutdown will have a negative impact to bearing next stage process system, the further raising of system for restricting output.
Summary of the invention
The object of invention: combine screening and separator and method for what a kind of diverse in function was provided, specific purposes are shown in multiple essence technique effects of concrete implementation section.
In order to reach as above object, the present invention takes following technical scheme:

Screening machine characteristic;
1, material wide adaptability: drum sieve is widely used in all kinds of material screenings, can sieve smoothly.2, feeding manner is simply various: no matter my the drum sieve charging aperture of company's development can, according to on-the-spot actual design, be belt, funnel or other feeding manner, need not take special measure, can smooth and easy charging.3, screening efficiency is high: equipment can be provided with comb type sieve cleaning mechanism, in screening process, no matter enter how dirty, many assorted can the screening of the material of sifting barrel, thereby has improved the screening efficiency of equipment.4, screening amount is large, be easy to maximize under same size, and the area of a circle is all large than the area of other type shape, and therefore its screening effective area is just large, makes material can fully contact screen cloth, thereby in the unit interval screening amount is just greatly.Again because it is simple in structure, arrangement convenience, the feature such as technology is novel and ripe, very easily maximizes.5, individual the drum sieve power of motor of company's development of self energy consumption is little, is 1/2nd to 1/3rd of other sieve type, processes same amount material and be only 1/2nd of other sieve type running time, and therefore energy consumption is low.6, the whole sifting barrel of good work environment can seal with seal isolation cover, has thoroughly removed the dust from flying in screening cyclic process, and block point the phenomenon such as spatters, avoided the pollution to working environment.7, the low drum sieve of equipment noise is in operation, and because speed of gyration is little, and has seal isolation cover to be isolated from the outside, and makes noise cannot be delivered to outside, thereby has reduced equipment noise.8, long service life, a little repair drum sieve is made up of several circular nets, and its total sieving area is far longer than the sieving area of other sieve type, add screening efficiency high, operation hours is short, so service life is longer, few easy workout part, maintenance are little.9, maintenance facilitates equipment seal isolation upper cover to take apart, does not affect machine and normally moves, and make to overhaul very convenient after taking apart.The cylindrical shell of drum sieve is made up of woven wire cloth or punched steel plate, and cylindrical shell is around the axle rotation of trunnion axis or slightly inclination.Cylindrical shell passes through chain, gear or friction gearing driven rotary by motor.The advantage of drum sieve is simple in structure, easily maintenance, management, and work balance is reliable, vibrates lighter.
Associating screening machine is mainly the material cake going out for breaing up roll squeezer roller, and by the material coarse and fine separation after breaing up out.From starting determining of transmission scheme, because the design combines the requirement of screening machine function, whole thinking is exactly Double-axis transmission, is first to break up part, and buncher is by the direct drive shaft rotation of belt transmission, drives that hammer is broken to be pulverized.Material is reached and break up requirement.Next is screening part, adopts motor to drive reductor to drive helical axis rotation, and helical axis drives helix rotation in drum sieve.Make material screening classification.Double driving system has been realized and has been broken up material and point requirement that stage material palpus consumes different-energy and different rotating speeds.To break up part and classification part separately, shorten the length of main shaft, in the service life of having improved like this two axles, optimize the design of axle, simpler in structure.
more than show and described general principle of the present invention, principal character and advantage of the present invention.Those skilled in the art should understand the present invention and not be restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed scope.
