2. Extrusion molding (rod making)
3. Carbonization (mostly kiln burning)
Most of these questions are in 2 and 3. Don't listen to others about how easy it is. As long as you learn, you can learn everything. There are many problems in this. As follows:
2. Extruded screws are the most likely to fail. As far as domestic extrusion technology is concerned, no one is willing to solve this problem.
If you have enough patience and skill, you can maintain it while producing. The screw breaks almost every three hours, so you have to keep disassembling it.
Welding and replacement. Spare 2-3 sets of screws can alleviate this problem)
3. Machine kiln has small output, high cost and high qualified rate. Earth kilns are cheap, and the qualified rate is uncertain, depending on the technology. Many only burned a pile of ash. Follow us.
The usual hardwood combustion methods are different, the humidity of the rod is different, and the temperature is different. First of all, small batch and many experiments were carried out to obtain the method before combustion in large kiln.
To tell the truth, don't believe in advertisements, you will be sad, especially the "head" company in the capital, which is a complete liar. If you really want to do this, you must see that they are.
Manufacturers, ask more people who use the equipment. Get first-line information.
In addition, pay attention to the price of sawdust over there, it is easy to rise, and carefully control the raw materials.
good luck
