The rolling and twisting type multistage grinder
Technical field
The present invention relates to a kind of corundum in granules disintegrating apparatus.
Background technology
The particle pulverizer of using is at present finished by the different grain size operation break-down, and granular mass is poor.Roll-type, jaw formula can only disposablely be finished a kind of granularity specification, and the compound crusher complex structure, price is high, and dust pollution is serious.
Summary of the invention
The invention provides a kind of rolling and twisting type multistage grinder and solved existing compound crusher complex structure, price is high, the technical problem that dust pollution is serious.
The present invention is by the above problem of following solution:
A kind of rolling and twisting type multistage grinder, comprise the pulverizer trough, in the pulverizer trough, be provided with pressure roller, the left side of the pressure roller in the pulverizer trough is movably set with the washboard seat with the arc medial surface, be fixedly installed the shelves seat with lozenges in the left side of washboard seat, between the left surface of the right flank of shelves seat and washboard seat, be movably set with wedge, be fixedly installed the jackscrew fixed head on the top of pulverizer trough, be bolted with the jackscrew that ejects in the screwed hole on the jackscrew fixed head downwards, the bottom of jackscrew and the top of wedge link together, between shelves seat and washboard seat, be provided with the double thread pull bar, the particle gap that forms between the arc medial surface of washboard seat and pressure roller is little gradual change slit, the large opposite side of side clearance gap, on the arc medial surface of washboard seat and the lateral surface of pressure roller be provided with and roll gear rolling.
Be provided with end to end rolling at the arc medial surface of washboard seat and rub the plane washboard with the hands.
The present invention is simple in structure, and the rolling and twisting type multistage grinder is simple in structure, and is cheap for manufacturing cost, can realize that on a machine multiple operation pulverizes step by step, granularity is pulverized step by step, epigranular, and quality is high, production efficiency is high, low cost of manufacture can arbitrarily be regulated the gap, the control product grading, washboard is conveniently replaced, and the squeezing process dust pollution is little.
