How to Choose Suitable Ring Die for Wood Pellet Mill

Ring perish lumber pellet mill is concentrated on making the timber pellets from all kinds of sawdust, straw, forestry wastes, wood chips and other farming waste materials. It is recognizable by the round "ring" form of their extrusion. As a fundamental part which determines the high quality of the timber pellet, it is vital to select proper ring die for the lumber pellet mill. These are instructions to select the ring die.

1. Pick the ring pass away based on the raw materials you use. Different raw materials requires various die gaps, porosity and compression ratio, so when deciding on the ring die of wood pellet mill, raw materials need to be taken into account.

2. Look for the materials call die utilized and its processing procedure. Ring perish normally made from carbon architectural steel, alloy structure steel or stainless steel and through machining, drilling, warmth procedure and other process, the raw materials are made into ring die. High quality ring die need to embrace vacuum warmth procedure.

3. Pay interest to the shapes of the die hole. There are different forms of die openings such as straight kind gap, pointered gap, outer cone gap and inner cone hole.

4. The roughness of the die gap likewise affects the high quality of the ring die. If the roughness is expensive, the top quality of the pellets will be poor. The die gaps of ring die drilled by gun-drill will certainly be more smooth. Choose effective compression proportion of ring die. The timber pellets made by ring die with high compression proportion is with higher thickness and additional smooth surface area. Various raw products calls for various die openings, porosity and compression proportion, so when deciding on the ring die of wood pellet mill, raw materials should be taken into factor to consider. Ring die normally made from carbon architectural steel, alloy framework steel or stainless steel and through machining, exploration, warmth treatment and other procedure, the raw materials are made into ring die. The roughness of the die hole also influences the top quality of the ring die. The die openings of ring die drilled by gun-drill will certainly be more smooth.
