Ring Die Wood Pellet Machine Introduction
Ring die wood pellet machine is specially designed for pressing combustible materials into solid wood pellets. It conducts large-scale or industrial wood pellet production and the end pellets can be used for fuel in fireplace, boiler, gasifier or biomass power plant. Equipped with a forced feeder, it can produce excellent wood pellets with high density and combustion value. Ring dies with different bore diameters can be customized according to clients’ different demands; here we would like to recommend the wood pellet mill with whole diameters of 8mm, 10mm, 12mm, etc. Solid pellets produced from which are proved incentive and smokeless.

Industrial Wood Pellet Press Features
☆It adopts professional forced feeder and strengthened transmission parts; the ring die, press roll and hoop are specially customized, robust and reliable.
☆Adopts high-precision gear driving so that the output is improved by about 20% compared with belt drive ones.
☆Imported high-quality bearings and oil seal are adopted to ensure efficient, stable and low-noise operation. The granulating room is equipped with air suction temperature-reducing system.

☆The feeder adopts variable frequency and speed-changing motor to prevent blockage and keep smooth feeding.
☆Stainless steel ring dies with multiple bore diameters for options, thus ensures the long service life and good pellet appearance.
☆International advanced compensation type snakelike spring coupling has the properties of novel and compact structure, high safety, low noise and low fault rate.

Ring Die Wood Pellet Mill Advantages
1. Ring die pellet mills generate less wear and tear since both inner and outer edges of the roller traverse the same distance.
2. Ring die pellet machines are more energy efficient than flat die wood pellet mill. Roller slip during the pelletizing process brings extra friction, but this extra friction is a good element in the production of qualified wood pellets due to the additional heat.
3. The ring die pellet mill has wide applicable scope. It can process different materials like wood chips, sawdust, straw, pasture, palm leaf, wood waste, wheat stalk, corn stalk and many other organic waste resources.

Notes on Biomass Pellet Raw Materials
Raw material types and features can exert great influence on biomass pellet production. For example:

wood pellets

--Biomass pellet made from hard wood has smaller productivity than that made from soft wood as hard wood like birch, elm are drier and denser than soft wood like pine, spruce and firs, thus wood pellet capacity is elastic.
--Raw material should not be completely fine powder, although the fiber material in powder is in favor of wood pellet forming, the powder should be 3-5mm,neither too small nor too big.
So for super quality wood pellets production, choosing the proper material type is significant.

How Does Ring Die Wood Pellet Mill Work
Ring die wood pellet press mainly consists of overload protection device, external discharging mechanism and pressurization oil pump lubrication system. The variable frequency and speed-changing motor is equipped for even feeding. The raw materials are delivered into wood pellet machine through a conveyor and then enter into a rotating ring die by a feeder, finally pulverized material will be pressed into ring die through two rotating press rollers. The resulting pressure compresses the material and extrudes it through the holes in the die. Then the pellet will be out directly.
