Abstract

The utility model discloses a machine, wherein, a rotor of the machine is arranged horizontally; the rotor is provided with hammers; a screen drum which counterattacks a grate plate is arranged out of the rotor; the rotor and the screen drum are respectively driven by two motors; the shaft line of the rotor keeps eccentricity e with the central line of the screen drum; the hammers on the rotor are alternatively arrayed without gaps along an axial direction. The machine has the advantages of large crushing ratio, high production capacity, low power consumption, good screening efficiency, uniform granularity and compact structure; the utility model can be widely used in the industry of building materials, metallurgy, chemical engineering, energy sources, etc. to finely crush various metallic and non-metallic minerals.

Description

The adjustable sieve fine crusher that revolves

The utility model relates to a kind of novel breaker in comminution engineering field.

The screen drum that existing impact breaker is equipped with counterpunch board rotates, but screen drum is coaxial with the pivot of rotor, and the distance of tup and screen drum is uncontrollable, thereby production capacity is low, power consumption is high, screening effect is bad, and many unsatisfactory places are arranged.

The purpose of this utility model provides a kind of fragmentation and screening is combined into one, and production capacity is big, and is low in energy consumption, the screening efficiency height, and discharging-material size is the adjustable sieve fine crusher that revolves uniformly.

The purpose of this utility model is achieved in that the horizontal placement of the rotor that tup is housed, the screen drum of counterattack grate plate is equipped with in the outside, rotor and screen drum are driven respectively by two motors, and the center line of rotor axis and screen drum has an eccentric distance e, and epitrochanterian tup does not have the gap vertically and is staggered.The counterattack grate plate is stairstepping or wave-like, and two ends of rotor is fixed on and is equipped with on the bearing block of adjusting screw rod and adjusting pad plate rack, and screen drum is made up of big running roller and counterattack grate plate, and screen drum is supported on little running roller.

Owing to adopt such scheme, after material enters fracture area, not only to be subjected to the strike repeatedly and the counterattack of tup and counterattack grate plate, also to be squeezed, comprehensive function such as shearing, material reaches release mesh after the effect of the power of various ways, can sieve thoroughly.This machine thereby to have a grindability big, discharging is even, does not have distinguishing features such as crushing phenomenon.

Be further described below in conjunction with drawings and Examples.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the left view that dissects of Fig. 1.

Among the figure: 1, support 2, adjustment screw rod 3, belt pulley 4, bearing block 5, main shaft 6, feed hopper 7, big running roller 8, outer cover 9, counterattack grate plate 10, rotor 11, tup 12, roller frame 13, pony roll wheel 14, adjustment gesture sheet 15, base 16, discharge bucket 17, rolling axle 18, hinge wheel 19, chain 20, minor sprocket 21, decelerator 22, motor 23, outer cover stent

In the accompanying drawings, the rotor 10 that tup 11 is housed is enclosed within on the main shaft 5, and main shaft 5 is contained in the bearing block 4 of support 1, and support 1 is fixed on the base 15, and rotor 10 can be adjusted and adjust pad 14 by the adjustment spiral shell on the support 12 and carry out up-down adjustment.Big running roller 7 and counterattack grate plate 9 have been formed broken screen drum; it is supported on the pony roll wheel 13 of roller frame 12; by decelerator 21 and motor 22 driven rotary, outer cover 8 is contained on the outer cover stent 23 rolling axle 17 by hinge wheel 18 minor sprockets 20, chain 19, in order to dustproof and safeguard protection.Material enters crusher chamber by feed hopper 6 and is discharged by discharge bucket 16 after hitting repeatedly.

Claims
