Drying crushing method for clay material and special device

Abstract

The invention relates to a method for drying and crushing muddy materials and a special device, and belongs to the technical field of mud mass crushing in the drying process of muddy materials. The technical solution includes the following steps: ①The muddy material enters the drum dryer from the feeding end, and the drum rotates, and the muddy material moves in the drum to the discharging end, and passes into the heat medium for heat and mass exchange; ②The drum is equipped with Several rods, the angle between the arrangement direction of the rods and the axis of the drum is less than or equal to 45 degrees; ③The muddy material collides with the rods in the process of moving to the discharge end in the drum, breaks, The dried muddy material is discharged at the discharge end of the drum. Beneficial effects of the present invention: light weight, less investment, no shedding, no noise; rods of the same length are installed along the axis of the drum dryer. Compared with the movable wing plate crushing device of the background technology, the total weight of the present invention It is only one tenth of the background technology, and the investment is also one tenth of the background technology. Reducing and eliminating noise is an important technical effect of the present invention.

Problems solved by technology

[0002] At present, during the drying process of muddy (coal slime, laterite and other muddy minerals) materials, due to their fine particle size, high water content, and high viscosity, they tend to be seriously balled up. The crushing device generally used in the background technology is "movable wing ", is a kind of grate-type crushing device with heavy and complex structure, which is extremely inconvenient to install and transport; installation method: "movable wing plate" is connected with the inner wall of the drum through bearings, and its bearing base is welded on the inner wall of the drum; "movable wing As the name suggests, the plate is to swing left and right with the rotation of the drum dryer to break up the mud balls.

The disadvantages of the above structure are: large investment, bulky, easy to wear, easy to fall off, loud noise
