Roller type crusher capable of automatically adjusting distance between rollers

Abstract

The invention discloses a roller type crusher capable of automatically adjusting a distance between rollers. The roller type crusher comprises a control system, a crusher outer shell and a pair of crushing rollers. The pair of crushing rollers is a crushing roller I and a crushing roller II. Both ends of the crushing roller I are mounted on the inner side wall of the crusher outer shell through bearings I. Both ends of the crusher roller II are respectively mounted on bearing installation bases II through bearings II. The bearing installation bases II are respectively mounted on electric sealing plates which can move front and back on the inner side wall of the crusher outer shell. The electric sealing plates and movable tightly-pressing devices form a coarse adjusting device for coarsely adjusting the distance between the crushing roller I and the crushing roller II. A fine adjusting device is mounted between the crushing roller I and the crushing roller II, and is a wedge capable of moving up and down in the vertical direction. The roller type crusher is simple in structure, reasonable in design, simple and convenient to operate, high in degree of intelligentization and good in using effect. The coarse adjusting device and the fine adjusting device are arranged, so that not only can the purpose of adjusting the distance between the rollers in a larger range be met, but also the precision-adjusting demand for the distance between the rollers can be satisfied.

Description

technical field [0001] The invention relates to a roller crusher, in particular to a roller crusher with automatic adjustment of the distance between rollers. 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 adjusted through the adjustment bolt installed on the top of the wedge: when the adjustment b...

Problems solved by technology

However, in the actual use process, the adjustment range of the distance between the two rollers by the above-mentioned wedges or spacers is small, and the adjustment accuracy of the distance between the rollers is not high, and the adjustment is inconvenient. Usually, repeated adjustments are required to Meet the design requirements of the output particle size
