A kind of new section coal production technology, adopts following steps to realize:
1) gangue, coal slime, coal dust are crushed to below 3mm respectively, and according to 1:(1-1.5): the ratio mixing of (0.25-0.5)；
2) using said mixture and water according to (4-7): the ratio of 1 also adds the shale of 3-5% as binding agent, after continuous stirring mixes, enters biaxial rneader stirring；
3) above-mentioned raw materials belt conveyor is delivered to brick making system and extruded；
4) by above-mentioned shaped article by, on marshalling code automatically to kiln car, being transported to acquisition briquet after dry kiln dries 24 hours；
5) according to the requirement of power plant, briquet being crushed to diameter is 8-10mm, is derived from industrial shaping coal.
Advantages of the present invention and providing the benefit that:
The art of this patent makes full use of low-grade coal and coal mining by-product, it is achieved that the recycling of garbage；Adopt existing brick-making technology, significantly save improvement cost, decrease investment, reduce risk, it is possible to make more enterprise carry out moulded coal production；The moulded coal that this technology produces is utilized to have the advantages such as calorific value height, comprcssive strength is high, combustion characteristics is good, sulphur-fixing and dust-fixing is effective.
