How to Prevent the Formation of Deficient Briquettes

In the process of briquetting coal powder, the deficient briquette formation may happen more or less to the coal briquette machine. With weak quality and poor briquette strength, these deficient briquetting products have much influence on the final briquetting rate of the coal briquetting plant. They are formed when the short time bridging phenomenon occurs, thus resulting in the briquetting molds are not full of enough crushed powder materials.


Zhongzhou briquette Machinery is a leading coal briquette press machine manufacturer and supplier with years' experience of solving the deficient briquette problem. Today our experts will share some useful solution to this trouble with customers.

1.Empty load running solution

Before the coal briquette plant or briquette machine is running with no load, there are several steps we need to take: make sure all installing screws and base bolts are tightened; test the lubricant oil volume of reducer, feeder and any other part; check if the triangle belt is in the proper tensioning condition; examine the standard oil pressure; make sure that there exists no foreign matter or abnormal problem inside the double roller hopper and other connecting parts.

2.Full load running solution

After we complete the empty load running examination, we can start to check the full load running condition of the coal briquette machine. Before starting up the equipment, make sure there is no foreign matter mixing between the distances of the double rollers.

When we finally start the coal briquette plant, we should listen and observe carefully in order to prevent abnormal rotating noise, loosening screws or heating bearings etc. Examine the current value of all electric motors and the oil pressure value.
