The importance of ring die in biomass pellet machine

Ring die is one of the main components in biomass pellet machine. It affects the production capacity and product quality of biomass pellet machine to a great extent. Therefore, the choice of ring die is very important for the use of biomass pellet machine.



1. The key of choosing ring die is to choose appropriate die hole and the roughness of the die. When new ring die is used in operation, check the production capacity of biomass pellet machine and the quality of pellets. If it can not reach the standard, and the operation indicators are abnormal, it indicates that the selected ring die doesn't match the products produced. Once this happens, you should reevaluate the specifications of the ring die or product formulation. Only one ring die can not apply to all products and make it both achieve the highest production capacity and the best quality products.

2. The design of the ring die affects the production capacity and product quality of biomass pellet machine to a great extent. Besides the thickness of the ring die, the specification of extruding hole should also be considered, such as the cone hole, taper hole depth, the length of the taper hole, angle and depth of the exit cone hole, etc.

Ring die in biomass pellet machine is the most important and the most easily damaged parts. Fracture of ring die often appear in the production of many users. Then, what is the reason that lead to the damage of ring die in biomass pellet machine?

1. Biomass pellet machine manufacturers may reduce the thickness of ring die in order to save raw materials. Due to the too thin thickness of ring die, its strength decreases, which would lead to the damage of ring die in biomass pellet machine after using for a period of time due to the stress. While common users probably won't pay attention to this problem, because it would not be fond by the customer in commissioning at the scene. Thus, when choosing the biomass pellet machine, the customer had better ask the specific materials and thickness of ring die.

2. Hard object is mixed when feeding in the biomass pellet machine in the process of running, the most common material is bearing ball or other metal objects. If these materials are dropping into the granulating chamber of biomass pellet machine, the ring die may get damaged at best. At worst, it is likely to hurt the pellet machine operators, so the inspection of raw materials must be strengthened.

3. The clearance between the roller and ring die is improper. If the clearance is too large, the forming degree of pellet is poor and the hardness is lower. While if the clearance is too small, the ring die may get damaged because of the too large pressure for a long time. So the user should adjust the clearance strictly in accordance with the manufacturer's instructions.

Thus it can be seen that to achieve the normal use of ring die in biomass pellet machine, the ring die should not only be selected properly, the operator should also operate in accordance with the rules of standardized operation in the later use, so that ring die in biomass pellet machine can play its normal level and create the highest economic benefit! Our company is specialized in design, production, installation, debugging and sales of complete sets of biomass pellet production equipment, sincerely welcome customers come to visit, we will serve you wholeheartedly!
