Double-layer roll crusher device

Abstract

A double-layer roll crusher device comprises a feeding portion, a crushing portion and a discharging portion which are arranged on a machine frame; a discharging outlet of the feeding portion is connected with a feeding inlet of the crushing portion; a discharging outlet of the crushing portion is connected with the discharging portion; the crushing portion comprises two roll crushers arranged upand down; and a discharge outlet of the upper roll crusher is connected with a feeding inlet of the lower roll crusher. The crusher device is uniform in feeding, good in synchronism and low in power consumption, and can meet the particle crushing requirement with the finished particle size being lower than 3 mm, double-layer two-stage crushing is conducted, and the crushing demands of raw materials of various specifications can be met.

Description

technical field [0001] The invention relates to a device for crushing particles, in particular to a device for crushing carbon-containing medium-hard materials, and belongs to the field of crushing machinery. Background technique [0002] Most of the existing crushers for crushing carbon-containing medium-hardness materials are double-roll crushers, which are mainly composed of a pair of crushing rollers, two gear motors, spring tensioning mechanisms and a casing. The two crushing rollers are each composed of a The reduction motor is driven by a V-belt, one of the crushing rollers is fixed on the casing through a bearing, the other crushing roller is fixed on the moving seat plate through the bearing seat, and then the moving seat plate is installed in the guide rail on the casing, and then It is tensioned by springs, the adjustment range of the roller distance is 5-40mm, and it is single-layer and first-stage crushing. This kind of double-roller crusher has the following sh...

[0002] Most of the existing crushers for crushing carbon-containing medium-hardness materials are double-roll crushers, which are mainly composed of a pair of crushing rollers, two gear motors, spring tensioning mechanisms and a casing. The two crushing rollers are each composed of a The reduction motor is driven by a V-belt, one of the crushing rollers is fixed on the casing through a bearing, the other crushing roller is fixed on the moving seat plate through the bearing seat, and then the moving seat plate is installed in the guide rail on the casing, and then It is tensioned by springs, the adjustment range of the roller distance is 5-40mm, and it is single-layer and first-stage crushing. This kind of double-roller crusher has the following shortcomings in use: 1. The feeding is uneven and the feeding amount cannot be controlled; 2. The minimum gap in the adjustment range of the roller distance is 5mm, which cannot meet the particle size requirement of the finished product below 3mm; 3. The two crushing rollers are respectively driven by two gear motors, so the synchronization of the two crushing rollers is poor, and the power consumption is large; 4. They are all single-layer one-stage crushing, which cannot meet the crushing of raw materials of various specifications.
