Abstract

The pulverizer is composed of fixed and movable rollers, lever, limiting pull device, triangle belt transmission system, owing to low speed upward rotation of the fixed roller and high speed downward rotation of the movable roller, the stuff is rubbed and pressed at the narrow gap between the rollers and is ground into powdered product, the rollers can be coated with corundum to increase their wear-resistance; when using as a pregrinder, it makes a ball mill save energy above 40%, raw stuff, coal powder and cement grinding can be carried out in the same pulverizer.

Description

Disintegrating mill with rolls

The present invention relates to the pre-grinding of the ore of cement industry in the comminution process, particularly a kind of disintegrating mill with rolls.

At present the ectrusion press that adopts is when the pre-grinding of ore, though make ball mill economize on electricity about 30%, but there is edge effect, the material middle and edge can not get sufficient extruding, and grinding mass conservation and two rollers that exist owing to extruder rotate and the deficiency of necessary service orientation joint adjusting potential difference and a plurality of motor, reductor in opposite directions.

This purpose provides a kind of disintegrating mill with rolls of two roller reverse rotations, realizes that raw material, coal dust, the cement production in the cement industry finished in machine, makes the raising of grinding quality and reaches the purpose of reducing investment outlay with electric energy.

Purpose of the present invention realizes by the technical scheme of following disintegrating mill with rolls.The disintegrating mill with rolls of forming by charging aperture, stationary roll and slide roller, lever, discharge gate, V-belt transmission system etc., the stationary roll and the slide roller of reverse rotation are installed below charging aperture, its stationary roll low speed rotates up, slide roller is rotated down at a high speed, thereby produce the rubbing and pressure effect, lateral surface at two rollers is equipped with striker plate, eliminates edge effect, also is provided with the spacing chest expander of control two roll gaps in the outside of slide roller bearing block.

This disintegrating mill with rolls is replaced extruder and the extruder again in " energy-saving pulverizing mill " (by my application, application number 93110832.2), and the preparation of raw material, coal dust, cement etc. is finished in machine.

Fig. 1 is a structural representation of the present invention, and accompanying drawing also makes an abstract.

Fig. 2 is A-A cutaway view among Fig. 1 of the present invention.

The present invention is further illustrated according to accompanying drawing below.

As shown in Figure 1, by the disintegrating mill with rolls that charging aperture 5, frame 2, stationary roll 3, slide roller 6, striker plate 4, powder outlet 1 etc. are formed, its afterburner system is made up of lever 7, counterweight 8; Stationary roll 3, slide roller 6 are by its

axle

18,20; Bearing 19,21;

Bearing block

17,22 supports; When treating that comminuting matter successively moves downward between two rollers by import 5, be subjected to afterburning lever 7 and pass to the extruding force of slide roller 6 by slide roller bearing block 22, bearing 21, axle 20, this extruding force is passed to stationary roll 3 by the rubbing and pressure material again, make under the rubbing and pressure state, material obtains high pressure rubbing and pressure fragmentation; When material comes downwards between two rollers the narrowest place, be subjected to the rubbing high pressure that two roller reverse rotations produce, make material obtain further rubbing and pressure grinding; Owing to be that reverse rubbing and pressure power can not produce material cake and the bed of material and is powdery and discharges this machine from powder outlet 1, enter another system.At the striker plate 4 that two roller lateral surfaces of this machine are provided with, cooperate slide roller 6 to be rotated down at a high speed, make thickness of feed layer reduce several times than extruder, eliminated edge effect and under-voltage material phenomenon.The two bearings outside in this machine slide roller 6 also is provided with spacing chest expander 23, in order to adjust two roll gaps, output, fineness when making work are controlled, when two

rollers

3,6 are installed on the

diaxon

18,20, its roll surface is on same center line the time, spacingly grinds generation mutually to two rollers and repairs roll surface from grinding.

Stationary roll 3 of the present invention and slide roller 6 all adopt the corundum material of Mohs thickness 9 to make, and compare the cover roller that the high-abrasive material of the built-up welding high pressure resistant that extruding force adopts is made, high several times of its hardness, and the high pressure resistant effect does not weaken yet, so the growth in service life;

The minicomputer running part that the present invention is shown in Figure 2, because having adopted two roller reverse rotations to produce rubbing and pressure pulverizes, thereby only use a motor 14 and a reductor 9, roll surface speed has afterburning effect with V-belt 11 and replaces the effect of universal joint, thereby not only slide roller 6 has been added power but also cancelled universal joint.If large-scale disintegrating mill with rolls then increases motor and reductor, and adopt the hydraulic jack reinforcing.

The present invention is owing to adopt stationary roll and slide roller reverse rotation, material is fully pushed, and rubbing and pressure are lacked power than lamination, can make the ball mill economize on electricity more than 40% when making pre-grinding, extruder in this machine replaceable " energy-saving pulverizing mill " and extruder again, accomplish that grinding operation lattices in each storehouse of machine such as raw material, coal dust, cement finish, make the grinding quality improve the purpose of reach energy-conservation, reducing investment outlay.
