Description

A kind of energy-efficient ball mill

Technical field

The utility model relates to ball mill technical field, specially a kind of energy-efficient ball mill.

Background technique

Ball mill is the key equipment that material is broken and then is crushed.This seed type ore mill is in its cylinder Interior to be packed into a certain number of steel balls as abrasive media, it is widely used in cement, silicate product, New Building Materials, resistance to The production industries such as fiery material, chemical fertilizer, black and non-ferrous metal ore and glass ceramics, to various ores and other grindability materials Carry out dry type or wet type grinding.Ball mill is suitable for the various ores of grinding and other materials, is widely used in ore dressing, building materials and change The industries such as work can be divided into two kinds of grinding modes of dry type and wet type.It is different according to ore discharge mode, it can lattice subtype and overflow type two Kind.

However present ball mill configuration is fairly expensive, due to ball mill barrel revolving speed and very low (per minute 15~25 Turn), it is such as driven with common motor, then the deceleration device for needing configuration expensive, works at the same time low efficiency, such as in production cement In the process, account for about the 2/3 of full factory for the electricity of comminution process, according to statistics, the power consumption of one ton of cement of every production is not less than 70 Kilowatt-hour, but the effective rate of utilization of this part electric energy is very low.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of energy-efficient ball mill, solves ball mill Energy consumption is high, ineffective problem.

Technical solution

In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of energy-efficient ball milling Machine, including device noumenon, the top of described device ontology are fixedly installed with feed inlet, are fixedly installed with below the feed inlet The internal activity of sieve material device, the sieve material device is equipped with turntable, and the inside of the turntable offers guide groove, the guiding The inside of slot is embedded with rotor, and the rotor is flexibly connected by connecting rod with sieve plate, and described device ontology offers rough lapping Chamber is fixedly installed with liner on the inner wall of the rough lapping chamber, is movably installed with reduction gear ring on the right side of the rough lapping chamber, institute It states reduction gear ring and is meshed by reduction gearing with driving gear, the inside of the rough lapping chamber is fixedly installed with hollow axle, The internal activity of the hollow axle is equipped with screwed pipe, and the bottom of described device ontology is fixedly installed with support base, the dress It sets and is fixedly installed with blow tank on the right side of ontology.

Further, the rough lapping chamber is connected by coarse fodder pipeline with feed inlet, and the hollow axle passes through fines Pipeline is connected with feed inlet.

Further, the rough lapping chamber is internally provided with steel ball, in the outer wall of the hollow axle is fixedly installed with Lining.

Further, the quantity of the reduction gear ring is four, and the reduction gearing is movably installed in fixation by shaft Four edges of frame.

Further, sieve pore identical in sieve plate is offered on the axial wall of the hollow axle.

Further, the screwed pipe is flexibly connected with driving gear by shaft.

Working principle: in use, material is poured into feed inlet, turntable drives rotor with guide groove by persistently rotating Contour motion, sieve plate by connecting rod with rotor associated movement, since the influence of guiding channel profiles makes sieve plate move reciprocatingly, With the reciprocating motion of sieve plate, the lesser material of particle enters hollow axle by fines pipeline, and the biggish material of particle is logical It crosses coarse fodder pipeline and enters rough lapping chamber.The strand generated into the lesser material of particle inside hollow axle in the screwed pipe of rotation It is ground under the influence of shear force.Liner belt animal is passed through by the rotation of rough lapping chamber into the material in rough lapping intracavitary portion Material and steel ball are rotated with rough lapping chamber, and when rotation is to certain altitude, material and steel ball are fallen under gravity, utilize steel The gravity of pearl crushes material, and pulverized material passes through the sieve pore being arranged on hollow axle axial wall and enters hollow axle Inside continue to grind, complete grinding material under the drive of screwed pipe, into blow tank in etc. it is to be removed.Due to rough lapping With the difference of revolving speed needed for hollow axle, the driving gear being connected with screwed pipe is directly driven by motor chamber, passes through work The engagement of the dynamic reduction gearing for being mounted on four corners of fixed frame, drives the reduction gear ring being connected with rough lapping chamber slow Rotation.Screening by sieve plate to material in advance comes out the feed separation of qualified fineness, reduces into the intracavitary portion of rough lapping Inventory, reduce the overground of material, do not only reached energy-saving, while improving grinding efficiency, meanwhile, pass through one Motor has also reached energy-efficient purpose without in addition adding other rate controlling equipment to control the revolving speed of ball mill.

Beneficial effect

Compare the prior art:
