Crushing and screening device for mine stone processing

Abstract

The invention discloses a crushing and screening device for mine stone processing. The crushing and screening device for mine stone processing comprises a processing machine body; a driving crushing roller is arranged in an inner cavity of the upper half portion of the processing machine body in a horizontal state; a driven crushing roller is further arranged in the inner cavity of the processingmachine body corresponding to the back of the driving crushing roller; a driven rotating gear is in transmission fit with a driving rotating gear in a gear meshing mode; a filter sieve tray is arranged in the inner cavity of the lower half portion of the processing machine body in a horizontal state; an extrusion reset spring is correspondingly arranged on a rod body on the left side of each guidesliding rod in a sleeving mode; a driven belt wheel and a driving belt wheel are in transmission connection through an anti-skid belt; a driving bevel gear and a driven bevel gear are in transmissiontogether in a gear meshing mode; and a force bearing seat and a force application cam are arranged in a force application and bearing fit mode. According to the invention, the crushing action and thescreening action are matched in a linkage mode, the design defect in a traditional mode that the two actions operate independently is overcome, and the high efficiency of screening operation is ensured.

Description

technical field [0001] The invention relates to the technical field related to mining machinery and equipment, in particular to a crushing and screening device for mining stone processing. Background technique [0002] The pulverizer is a machine that crushes large-sized solid raw materials to the required size. The pulverizer is composed of devices such as coarse crushing, fine crushing, and wind conveying. It achieves the purpose of the pulverizer in the form of high-speed impact. The screening procedure of the ore stone processing pulverizer is a device for crushing the stone. The stone needs to be crushed before it can be processed next. According to the size of the crushed material or the crushed material, the high-efficiency crusher can be divided into two types Coarse Crusher, Medium Crusher, Fine Grinder, Superfine Grinder. There are four kinds of external forces applied to the solid during the crushing process: rolling, shearing, impact, and grinding. Rolling is m...

Problems solved by technology

[0004] In the stone processing of mines, we need to use stone crushers. After crushing the stones through the stone crusher, we can process the crushed stones. However, the commonly used stone crushers have similar crushing effects on stones. It is guaranteed to be 100% crushed into the desired shape, so the crushed stones must be screened, but the entire filter sieve plate in the existing equipment is designed to be fixed and immobile, and the screening operation of the filter sieve plate on the crushed stone The efficiency is low, the crushing action and the screening action can not be effectively "linked" to cooperate, the traditional method has design drawbacks that the two actions operate independently, the screening efficiency is low, and the screening effect is poor

[0005] Therefore, in order to solve the defect of poor screening effect in the prior art, we propose a crushing and screening device for mine stone processing
