Abstract

The invention belongs to the technical field of coal preparation machine, and particularly relates to a crushing and screening device for a coal mine. The crushing and screening device comprises a hinged crusher, a bracket, a belt conveyor and a parallel vibrating screen, and the hinged crusher comprises a driving shaft support, a box body support, a box body and a motor; both the box body supportand the driving shaft support are welded on the bracket, and the motor is installed on the bracket; and the box body is fixed to the support by a bolt, and the outer wall of the box body is providedwith a controller. According to the crushing and screening device, the crusher can be prevented from being damaged when large and hard gangues or other sundries can not be crushed; it is ensured thatthe crusher works properly, and lump coal can be extruded, split, broken, ground and crushed through a crushing hinge; crushing forms are diversified, and the crushing effect is good; when large-diameter gangues are separated, the falling amount of unbroken lump coal is reduced, and the workload for re-crushing the unbroken lump coal in the later period is reduced.

Description

technical field [0001] The invention belongs to the technical field of coal preparation machinery, in particular to a crushing and screening device for coal mines. Background technique [0002] Coal is an important energy source in my country, and the green and efficient use of coal resources has always been an important research topic. Sorting and processing raw coal can produce high-quality coal products, effectively reduce pollutant emissions, reduce transportation volume, and improve energy utilization. [0003] In the coal preparation plant, the crushing operation can meet the user's requirements for the particle size of the lump coal and reduce the content of gangue in the coal. When the crushing machine is working, it is required to have sufficient strength and reliability due to the resistance caused by lump coal, gangue and other sundries. When crushing ore with high strength, it is easy to cause wear of the crushing teeth. It may even cause damage to the crusher...
