The coal rod machine adopts a hard tooth surface reducer, which is small in size and high in bearing capacity. The impeller inside the coal rod extruder is designed with thickened blades, the impeller and the inner lining plate of the cylinder are made of wear-resistant precision casting materials, and the service life is 4-5 times longer than that of ordinary materials; the coal rod outlet at the head of the machine is replaceable. Made of wear-resistant alloy steel, easy to replace. The machine head and the barrel are in the form of articulation, which can be opened during maintenance, and it is very convenient to replace the internal impeller and barrel lining.
working principle
The rotating impeller sandwiches the raw coal from the feeding port and pushes the coal forward, the raw coal is gradually compressed, the particles are close together, and at the same time, a relatively large agitation and mixing are generated. At this time, strong friction and shear are generated between the raw coal particles, the particles and the blades and the simplified body. At the same time, under the action of heat generation, the temperature of the raw coal rises, the moisture and binder are more uniform, and the plasticity of the coal is also greatly increased. After the constriction of the conical body of the mold, the coal particles are compressed more closely, and then pressed into the flat part of the mold, and the coal rod machine is formed.
Installation and commissioning:
1: Before installation, all parts must be thoroughly cleaned to remove rust from transportation or storage for a long time, and check whether the parts are damaged.
2: Concrete the foundation according to the foundation drawing, and leave screw holes. After the concrete is solidified, hang the coal rod machine on the concrete foundation, align the screw holes, and grouting the concrete twice. After the anchor screws are solidified, use a level to calibrate The machine can be tested after the machine is stable.
Before testing the machine, lubricate each lubricating part with a moderate amount of oil. Check all bolts for looseness and tighten them. Jog the machine to see if there is any foreign object or abnormal sound. Everything is confirmed to be correct before starting the operation. And check whether the power direction is correct.
After the machine runs empty for 3 to 5 minutes, everything is normal and can be put into trial production. The new machine should be evenly fed with moderate dry and wet (generally 12% to 15% moisture content).
