A Double Roller Crusher with Automatic Screening

Abstract

The invention relates to the technical field of mining machinery and equipment, and discloses a double-roller crusher for automatic screening, which includes a casing, the upper end of the casing is fixedly connected with a feeding port, and one side of the middle part of the casing is movably socketed with a driving roller , the other side of the middle part of the housing is movably sleeved with a rotating shaft, and the middle part of the rotating shaft is fixedly connected with a movable roller. Through the setting of the arc-shaped filter screen and the transmission rod, when the double-roller crusher is working, since the double-roller will rotate and crush the material, the movable roll will squeeze the material at the same time under the action of the safety spring. And repeatedly move left and right (similar to left and right vibration), through the setting of the transmission rod and the arc filter, the left and right vibration of the movable roller can be transmitted to the arc filter to enhance the vibration of the material, not only can the arc filter be crushed The final material is screened, and the arc-shaped filter screen can be vibrated, so that the broken material above the arc-shaped filter screen can be filtered faster, preventing material accumulation and affecting the filtration and screening efficiency.

Description

technical field [0001] The invention relates to the technical field of mining machinery and equipment, in particular to an automatic screening double-roll crusher. Background technique [0002] Double roll crusher, a kind of mining machinery, also known as double roll crusher, is mainly used for crushing ore. This machine has the advantages of small size, large crushing ratio, low noise, simple structure and convenient maintenance. The crushed material has uniform particle size, low over-crushing rate, convenient maintenance, sensitive overload protection, safe and reliable, etc. It is suitable for coal, metallurgy, mining, chemical industry, building materials and other industries, and it is more suitable for crushing raw coal (including gangue) in large coal mines or coal preparation plants. Its principle is to use two oppositely rotating rollers to crush materials. The roller crusher is composed of a motor, a bracket, fixed rollers, movable rollers and safety springs. M...

Problems solved by technology

[0003] However, the existing double-roll crusher still has shortcomings in the actual use process: in the current double-roll crusher, when the super-hard material passes between the two rollers, one of the rollers will automatically avoid it, so the super-hard material will pass through the two rollers. Between the rollers, the materials that fall at the same time as the super hard materials are stretched by the pair of rollers due to the super hard materials, so the materials are not crushed during this time, resulting in a large amount of materials that are not crushed before being mixed with the crushed materials. The crushing efficiency is seriously reduced, so after the crushing of the material is completed, the material needs to be screened to remove the hard material
