Description

Technical Field

[0001] This utility model relates to the field of coal washing and drying technology, specifically a coal washing and drying equipment with rapid drying function. Background Technology

[0002] Coal washing is a process of processing, sorting, and purifying raw coal through physical methods. The purpose is to improve the quality of coal, remove impurities (such as gangue, silt, and harmful components like sulfur), and make the coal suitable for subsequent industrial production and use.

[0003] While traditional coal washing and processing equipment can dry coal through methods such as drying, it still faces the problem of not being able to dehydrate the coal. Wet coal contains a large amount of free water (surface water) and some capillary water (internal moisture). Direct drying without dehydration will significantly increase the load on the equipment. The heat energy is first used to evaporate a large amount of free water, which prolongs the actual drying time. Moreover, during the drying process, the vaporization of moisture in the wet coal particles will generate a large internal and external pressure difference, which can easily lead to the breakage of coal particles.
