Abstract

A kind of mould coal contains 60-90%(w) coal-washed mud, 10-20%(w) ocher. First, mix round evenly the components in the coal moulder and then add 1-5% water to it. Secondly, mix around evenly in the blender. Finally, put the compound into coal moulder for extrusion. The source of this invention can be gained abroad and it has a simple production and low cost. Additionally, the mould coal can be easily transported and hardly broken up. Moreover, because it is no ash when being stored, it can reduce the pollution to the environment. And it advances the deep processing of the flotsam. Also, the cost of this kind of mould coal is cheaper by 80-100 yuan per ton than crude coal.

Description

technical field [0001] The invention belongs to a briquette fuel, in particular to a coal slime briquette. Background technique [0002] At present, coal washing slime is a kind of fine-grained, high-moisture, low-quality fuel discharged during washing and processing in the coal industry. Many coal washing plants put the coal washing slime directly into the coal market for sale without any treatment, and many users who use coal washing slime place it in open places. , frozen into a whole piece in winter in the north of my country, time-consuming and labor-intensive to use, in summer, long-term placement becomes powdery, easy to produce coal dust, causing serious environmental pollution, the Patent Office of the State Intellectual Property Office on June 3, 1998 The disclosed spherical particles of coal washing slime and its preparation method are characterized in that the coal washing slime, curing agent and dehydrating agent are mixed, dehydrated, stirred, rolled, stirred, fo...
