Problems solved by technology

[0006] The purpose of the present invention is to: aim at the above-mentioned problems, to provide a double-roller crusher. By setting two groups of springs to cooperate with each other, the automatic balance speed of the rollers is accelerated, and the existing double-roller crusher is solved due to the automatic balance. The speed is slow, resulting in uneven particle size of crushed materials and low crushing efficiency.

Abstract

The invention discloses a double-roller crusher, which belongs to the field of mining machinery. The roller crusher includes a body, a motor, a transmission, a roller shaft and rollers, and the body is provided with a roller shaft and rollers; The shaft device is connected with the transmission, and the transmission is connected with the roller shaft; the roller shaft and the roller are connected by splines; the roller shaft includes the driving roller shaft, the driven roller shaft 1 and the driven roller shaft 2, and the corresponding roller shaft is provided with a driving roller 1. Passive roller 1 and passive roller 2; the body is provided with a feeding port, and a screen is provided in the feeding port. Through the above structural design, the uniformity of the particle size of the material crushed by the crusher and the crushing efficiency of the crusher are effectively improved.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a double-roller crusher. Background technique [0002] Double Roller Crusher (Roller Crusher\Roller Crusher\Double Roller Crusher) is suitable for crushing medium-hard materials in mining ore, cement, chemical industry, electric power, metallurgy, building materials, refractory materials and other industrial sectors, such as Medium and fine crushing of limestone, slag, coke, coal and other materials. [0003] This series of double-roll crushers is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices. [0004] Adjustment of discharge granularity: a wedge or gasket adjustment device is installed between the two rollers, and an adjustment bolt is installed on the top of the wedge device. When the adjustment bolt pulls up the wedge, the wedge pushes the movable roller away from the fixed wheel. , That is, the gap between the two ro...
