Problems solved by technology

When crushing copper, iron, chromium and other ores, the roller crusher is generally used, and the gap between the driving roller and the driven roller should be adjusted according to the size of the ore. Generally, the movement of the transverse tension beam is adjusted by the screw at the front of the frame, and the bearing seats on both sides of the driving roller are adjusted synchronously. The centerlines of the driving and driven rollers are parallel, that is, the centerlines of the driving and driven pulleys are parallel. After a period of use, the output size is often not well controlled, the belt often jumps out, and even the bearings are worn and the adjustment mechanism is bent and deformed and cannot be used. Waiting for failure
Other types of double-roll crushers are multi-bearing fixed, or nuts are used on both sides of the driving roller to adjust separately. inconvenient

Abstract

The invention discloses a double-roller crusher comprising a pedestal frame, a roller support, a driving roller, and a driven roller. The roller support is arranged on the pedestal frame. The driving roller is arranged on a driving shaft, and the driven roller is arranged on a driven shaft. The driving shaft and the driven shaft are arranged in parallel on the roller support. The crusher is characterized in that a roller space adjusting device is arranged on the driven roller. The crusher has the advantages that the double-roller crusher is easy to adjust and hard to be blocked, and has low failure rate.

Description

technical field [0001] The invention relates to a crusher, in particular to a pair of roller crushers. Background technique [0002] In the field of metallurgy and mining, it is generally necessary to crush ore for transportation and testing. When crushing copper, iron, chromium and other ores, the roller crusher is generally used, and the gap between the driving roller and the driven roller should be adjusted according to the size of the ore. Generally, the movement of the transverse tension beam is adjusted by the screw at the front of the frame, and the bearing seats on both sides of the driving roller are adjusted synchronously. The centerlines of the driving and driven rollers are parallel, that is, the centerlines of the driving and driven pulleys are parallel. After a period of use, the output size is often not well controlled, the belt often jumps out, and even the bearings are worn and the adjustment mechanism is bent and deformed and cannot be used.
