Abstract

The invention discloses a roller-crusher roller-distance automatic-adjustment device. The roller-crusher roller-distance automatic-adjustment device comprises an adjustment control system, a coarse adjustment mechanism and a fine adjustment mechanism. A pair of crushing rollers comprises a fixedly installed crushing roller and a movably installed crushing roller. Two ends of the movably installed crushing roller are installed on a housing by a bearing. A bearing installation base is installed in the center of an electric seal plate which can move forwards and backwards along the inner side wall of the housing. The electric seal plate is fixed on the side wall of the housing by a movable pressing device. The electric seal plate and the movable pressing device form the coarse adjustment mechanism. The fine adjustment mechanism comprises left and right wedge blocks arranged between left and right ends of the pair of crushing rollers. The left and right wedge blocks are respectively driven by a motor to move upward and downward. The roller-crusher roller-distance automatic-adjustment device has a simple structure and a reasonable design, can be operated simply, has a high intelligentization degree and good use effects, utilizes cooperation of the coarse adjustment mechanism and the fine adjustment mechanism, and satisfies requirements on roller-distance large-range adjustment and roller-distance precision adjustment.

Description

technical field

[0001] The invention belongs to the technical field of adjusting the distance between rollers of a roller crusher, and in particular relates to an automatic adjustment device for the distance between rollers of a roller crusher. Background technique

[0002] Roller crusher, also known as double-roller crusher, double-roller crusher or double-roller crusher, is suitable for crushing medium-hard materials in the fields of cement, chemical industry, electric power, metallurgy, building materials, refractory materials, etc., such as Medium and fine crushing of limestone, slag, coke, coal and other materials. This series of double-roll crushers is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices. In actual use, when the existing roll crusher adjusts the discharge granularity, it mainly uses wedges or gaskets installed between the two rolls for adjustment. When the wedge is used for adjustment, it is adjuste...
