Embodiment Construction

[0014] The base material is spheroidal graphite cast iron, cast steel or other materials. The process is as follows: rough turning-turning trapezoidal groove (using a cemented carbide turning tool with the same cross-section as the trapezoidal arc strip)-milling groove (used to put hard Alloy strip 4)-Put the cemented carbide trapezoidal arc strip 3 and the cemented carbide strip 4 into the corresponding grooves-put the sealing ring in and weld it with electric welding on the outside-use high-frequency welding or oxygen Welding copper firmly welds the cemented carbide trapezoidal arc strip 3 and the cemented carbide strip 4 with the base material-rough grinding on a surface grinder-precision machine-drilling-tapping on a surface grinder -Inspection-warehousing. Install the qualified movable grinding head and fixed grinding head on the main shaft and fixed grinding head support respectively, put the coarse-grained rubber containing a certain proportion of fine steel wire into th...

Abstract

The invention relates to a high-efficiency special powder mill, which belongs to powder-milling equipment of waste and old tyres and solves the problems that finer rubber powder which is formed by crushing coarse rubber powder has low yield, is sticky and is not easily sieved in the prior art. The high-efficiency special powder mill is mainly characterized in that a certain proportion of fine steel wires are mixed into the coarse rubber powder to enter the powder mill for milling the powder.

Description

Technical field [0001] The invention belongs to a crushing machine and is mainly used for fine crushing of waste tires. Background technique [0002] The currently used pulverizer is to crush the tire into coarse rubber powder (usually 5-20 mesh) through a shear crusher or a pair of roller crusher, and deliberately remove the steel wire in the tire with a magnetic separator. Then it is milled. [0003] The mills currently in use work like this: figure 1 As shown, the rubber particles are added to the feeding hopper 31, and the rubber particles are transported to the storage space of the fixed grinding head 10 and the movable grinding head 11 through the feeding screw 6. The movable grinding head 11 is mounted on the main shaft 13, and the fixed grinding head 10 Installed in the right end of the fixed grinding head bracket 9, loosen the locking handwheel 23, turn the adjustment handwheel 29 clockwise, adjust the pinion 24 through the reduction box 30, drive the adjustment gear 22 t...
