Description

Technical Field

[0001] The utility model relates to the technical field of coal preparation, in particular to a coal preparation machine. Background Art

[0002] Coal preparation is also called coal washing, which is the process of selecting clean coal that meets the quality requirements of users from raw coal. Coking coal has certain requirements for ash and sulfur content, and clean coal that has been washed must be used. The petrographic composition of coal and the quantity, type, nature and distribution of minerals in coal are all factors that affect the selectivity of coal. According to the difficulty of raw coal selectivity, the commonly used coal preparation processes include jigging, heavy medium shallow tank, heavy medium cyclone, dynamic screen jigging, flotation, air separation, spiral separation, etc.

[0003] When working, coal preparation machines usually need to crush the raw coal and then screen it into coal blocks of different sizes. At present, most coal preparation machines on the market only crush the raw coal through a crushing device and then screen it through a screen. However, after crushing, the material is usually stuck at the feeding port, causing blockage and affecting the operation of the motor, thereby causing damage to the motor. At the same time, the coal cannot be evenly distributed in the screen after feeding, resulting in the coal piled together during the screening process cannot be fully screened, which affects the subsequent use.
