Products Description

The coal rod extruder is a machine that extrudes coal powder after mixing it with a mixer and adding a binder. It increases the value of coal powder and improves its utilization rate. What links should be paid attention to in the production process of the coal rod extruder?
The diameter of the coal rod should be φ18-φ22. If it is too large, it will be difficult to burn through and increase the coke return. The diameter of the discharge port of the coal rod machine head is φ18. With the wear of operation, the discharge port will gradually become larger. When it is larger than φ22, the machine head should be replaced to ensure the quality of the coal rod. For φ3 000 and φ3300 gasifiers using coal rods as raw materials, the diameter of the coal rod can be slightly increased.

Product Analysis

The strength of coal rods has a great influence on the gasification level and is the main control indicator of enterprise production. The strength of coal rods can generally be measured by a drop test, that is, 10 rod samples are taken each time, and they are repeatedly dropped from a height of 1m until they are longitudinally broken and cracked. Generally, more than 6 times are qualified, and the qualified rate can reach 90%.
It is also very important to put cold coal rods into the furnace. The moisture content of the newly made coal rods is about 14%. When entering the furnace, the moisture content of the coal rods can be reduced by 2% to 4%, which not only increases its cold strength and thermal stability, but also avoids the pulverization caused by the rapid evaporation of moisture after entering the furnace. At the same time, it also shortens the thickness of the dry distillation layer, increases the effective carbon layer, and improves the gasification strength.

The bonding effect of the coal rod machine directly affects the quality of the coal rods produced, so it is urgent to improve the bonding effect of the coal rod machine when producing coal rods.
1. Control the moisture content. Too much or too little moisture content will affect the contact effect between coal particles and binders. Only by controlling the moisture content between 12% and 14% can the bonding effect of the coal rod machine be improved;
2. Increase the coking component of the binder itself. The amount of coking component contained in the binder determines the thermal stability of the coal rod, because the coking component plays a bridge role between coal particles in the process of making coal rods. Therefore, increasing the coking component of the binder itself is very important for improving the bonding effect of the coal rod machine.
3. Increase the retting time of coal powder. The raw materials used in processing coal rods must be retting for a period of time. Only in this way can the binder and coal powder be fully contacted. The length of the retting time directly affects the contact time between coal powder and binder. Only by increasing the retting time of coal powder can the bonding effect of the coal rod machine be improved.
