High-efficiency coal crushing and screening apparatus

Abstract

The invention discloses a high-efficiency coal crushing and screening apparatus. The high-efficiency coal crushing and screening apparatus comprises a pedestal, a crushing apparatus is arranged at oneside of a top part of the pedestal, two sides of the top part of the crushing apparatus is respectively connected with a driving wheel and a driven wheel through a mounting base, the driving wheel isconnected with the driven wheel through a conveyor belt in a transmission mode, a rotating shaft of the driving wheel is connected with the rotating shaft of a first motor, and two sides of the top part of the crushing apparatus are respectively and fixedly connected with a support plate. Through combination of the crushing apparatus and the screening apparatus, a processing operation of coal issimplified, coal processing efficiency is increased, artificial operation for coal screening is not required, manpower is saved, screening efficiency of the coal is increased, multitime screening canrealize multi-step screening, coals with different particle sizes can be completely classified, overlow or overhigh crushing quality can be prevented, and the coal crushing quality is increased.

Description

technical field [0001] The invention relates to the technical field of coal processing equipment, in particular to a high-efficiency coal crushing and screening device. Background technique [0002] Coal plays a very important role for us. Coal is mined in the form of lumps. Not only should coal be crushed and screened when it is used, in order to fully burn coal, but also to process coal into briquettes, it needs to be crushed and screened first. The crushing and screening devices are not only two separate processes, the operation is cumbersome, wastes time, and reduces the coal processing efficiency, but also the screening devices are manually screened, which wastes manpower. People work for a long time and are prone to fatigue, which reduces the coal screening. Efficiency, because the sieve can only screen one kind of pulverized coal that needs to be screened, the coal particles after screening are inconsistent in size and cannot be completely classified, and the pulveriz...

People work for a long time and are prone to fatigue, which reduces the coal screening. Efficiency, because the sieve can only screen one kind of pulverized coal that needs to be screened, the size of the coal particles after screening is inconsistent, and cannot be completely classified, and the pulverized coal will not meet the quality requirements, which will affect the pulverized quality of coal
