Description

Spiral blade type coal slime crusher

Technical Field

The utility model relates to the field of coal slime filter cake crushing and processing equipment, in particular to a spiral blade type coal slime crusher.

Background

At present, a filter press is commonly adopted in domestic coal washing plants to recover coal slime, and because the coal slime has high moisture, high viscosity and high storage and operation difficulty, the coal slime is extremely difficult to sell as commercial coal, so that a large amount of coal slime is accumulated, and the coal slime accumulated in the open air runs off when meeting water and flies when meeting wind, thereby causing serious pollution to the environment.

Under a new intensive economic mode, how to reduce cost and improve efficiency is a common problem faced by various coal mine enterprises. The main treatment modes of the existing coal slime filter cake include direct discharge, drying treatment and mixing after crushing. The direct discharge can cause resource waste and environmental pollution, and the drying treatment of the coal slime has high cost, high energy consumption and complex system. If the particle size of the mixture is large and uneven after crushing, the coal quality is unstable. If the coal slime is crushed into small and uniform granularity and is directly and uniformly mixed with the slack coal to form flowable mixed coal, unnecessary quality disputes caused by the sampling deviation even caused by the appearance of large blocks can be avoided, the enterprise benefit can be improved, the efficient utilization of resources is realized, and the coal slime crusher can crush and process the small particles of the coal slime.

The traditional coal slime crusher adopts a plurality of blades to shear materials to realize crushing, two main shafts rotate oppositely when crushing the materials, the materials directly enter downstream equipment through the shearing and crushing of the blades, and the traditional crushing structure can not completely crush the materials and can not ensure the size and uniformity of discharged granularity; moreover, the traditional coal slime crusher is easy to have the problem of blockage if the coal slime is wet in the processing process.
