Pressure adjust methods: mechanical type and hydraulic type two kind;
Application: used to press difficult to form powder material;
Features: high forming pressure, main machine working speed can be adjusted;
Main used to press coal powder forming, dry powder forming, ore tailings forming, etc.
1.Feeding raw materials: coal briquette machine maind used to press coal slime, coal powder and coal slag, etc.
2.You should grasp coal briquette machine two feeding methods:
a.Belt conveyor feeding, this feeding method with advantage of low cost, but with disadvantage of not good output briquettes;
b.Pre-press spiral feeder feeding, the spiral feeder feeding main advantage is you should limit the feeding capacity in advance, only feeding engough, it can output good briquettes.
1.Material size should at the range of 90-260mesh;
2.There isn't any metal material in the raw material, otherwise will damage roller skin surface;
3.You should make sure feeding enough, it's better adopt speed adjustable spiral feeder to view return material amount to re-adjust new material feeding capacity;
4.Before feeding, you must make the machine working without any raw material load in several cycles then start feeding to prevent briquette machine feeding too much and lead to the speed reductor and motor over loading and then broken the briquette machine roller shaft.
