1. The particle size of the powder to be pelleted should be in a certain proportion: generally, the material is less than 2/3 of the diameter of the circular mold hole and all pass through the sieve.
2. The moisture should be controlled at 15%~18% after tempering. The molding rate is higher and the density is larger when the moisture is even.
3, there should be a magnetic separation device before pelletizing, so that the mold will not be broken, to avoid unnecessary losses.
The true center of the sawdust particle mechanism granulation process is the press roll entrainment point or the feed wedge between the roll and the press die. Almost all other equipment in the wood pellet plant is an auxiliary equipment for the most critical part of it. There are three pressure points:
1. The roller acting on the material squeezes the material into the die.
2, the pressure mold itself has a kind of resistance, this resistance can prevent the material flow over the pressure mold hole.
3. The pressure exerted by the roll is combined with the friction pressure generated by the roll itself in the formula. This pressure causes the material to be pressed and prevents the material from being ejected along the surface of the die in front of the roll. When we increase the adjustment value of the variable speed drive or control and increase the feed quantity of the sawdust pellet mill, we routinely thicken the material quantity just in front of the roll. In other words, it is necessary to have a greater force to push the material into the pressure roll into the point, rather than into the pressure.
Anyway, grain quality and yield of products, with sawdust particles machine operator's quality are closely related. They must be based on the change of ambient temperature, humidity, moisture content, granularity of powder change, the adjustment of the formula and equipment wear and the special requirements of customers, production of qualified particle material. To produce high quality products, the staff must have a comprehensive knowledge, rich experience and strong sense of responsibility, overcome difficulties, to produce high quality products. Our company is specialized in research and development production of biomass pellet mill, mature technology, leading product is complete, it is one of the country's top biomass energy Manufacturers, in this sincere welcome to our customers to visit the company!
