There are many types of equipments for sieving and crushing. The crushing capacity ranges from 80 to 780r per hour, which can meet the requirements of different molding process. It is very important to control the crushing particle size reasonably to get the maximum bulk density. Usually, lignite is crushed to smaller than 5mm and about 50% less than 2mm. Avoid producing too much coal powder during the crushing since it can cause dust problems when drying, even lead to spontaneous combustion explosion.
