Abstract:
     The invention offers a kind of craft for separating pillars in the coal powder. It includes three parts of mineral liquid preparation, pillar separate choosing, and product off water. It uses double liquid pillar and material and water-off equipment, and then makes the pillar-box press filter craft, taking off the carbon grains not fired in the coal powder. Put the high carbon coal and water into the mixing bucket, through mixing the mineral liquid is made, transfer it to the entrance of pillar, by the separating choosing, we get pure mineral and the mineral coal powder, through box press filter machine, we get the carbon product and coal powder product. The advantages of the invention are: simple craft, little cost, little energy, and repair little, operating cost little.
