Coal crushing device having separation function

Abstract

The invention discloses a coal crushing device having the separation function. The coal crushing device comprises a base. The top end of the base is provided with a feeding motor and a main rack. Thefeeding motor is located at one side of the main rack. A feeding roller is connected to one side of the feeding motor in a rotary manner through a rotating shaft. The coal crushing device is providedwith a material delivery sieve plate bracket, a coal powder collection plate and a coal briquette hopper; coal briquettes are conveyed onto the material delivery sieve plate bracket through a discharging opening; the small-particle coal briquettes in the coal briquettes are sieved out through a coal powder sieve plate at the inner side of the material delivery sieve plate bracket, and coal powderobtained after sieving falls onto the coal powder collection plate; the large coal briquettes pass through the inclined coal powder sieve plate, fall into coal powder leakage holes, pass through the coal powder leakage holes and fall onto the coal briquette hopper, and thus, the large coal briquettes needing to be crushed can be delivered into a crushing barrel conveniently; and the problems thatwhen a coal crushing device is used, coal is difficult to separate through the coal crushing device, so that large coal briquettes and coal powder are pulverized at the same time, crushed coal adheresto the interior of a crusher, and the application effect of the coal crushing device is affected are avoided.

Description

technical field [0001] The invention belongs to the technical field of coal crushing, and in particular relates to a coal crushing device with a sorting function. Background technique [0002] The coal crushing device is a new research and development equipment for the coal industry. The coal crusher is mainly for the difficult problem of crushing coal with high moisture content. The alias of the coal crusher is also called the double-stage crusher, which belongs to the high-efficiency fine crushing equipment. The appearance of the coal crusher , It solves the problem of clogging when crushed because of the high moisture content of the material. The biggest advantage of the coal crusher is that it can be produced normally even in rainy days. [0003] However, when the existing coal crushing device is working, when the coal crushing device is used, it is difficult for the coal crushing device to separate the coal, so that the larger coal lumps and coal powder are crushed at t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a coal crushing device with a sorting function to solve the problem that when using the existing coal crushing device, it is difficult for the coal crushing device to separate the coal, so that larger coal lumps and coal powder are crushed at the same time, The crushing sticks in the pulverizer, which affects the use effect of the coal crushing device, and the crushing barrel of the coal crushing device needs to be fixed with another outlet, which affects the user experience of the coal crushing device. At the same time, the user needs to pour the coal into the crushing device The equipment crushes coal, which affects the convenience of using the coal crushing device, and it is difficult for the coal crushing device to dry the coal, and the moisture content of the coal is too high, which affects the crushing effect of the coal crushing device
