Crushing Machine

Why Need Wood/Feed Crushing machines
The biomass crushing process plays an important role in crushing raw materials for a complete pellet line. But there is one thing to point out is that before starting the operation you should have a clear understanding of the material size. Then you can choose the most suitable machine for your processing. According to different material sizes, we offer you two kinds of wood crushing machines, that is a wood crusher and a hammer mill. Hammer mills can also be classified as feed hammer mills and wood hammer mills.

Wood Crusher Highlights
Wood crusher is an ideal equipment for pellet mill production line which is used to process logs, square blocks, wood staff, etc with sizes less than 200mm (diameter). After the material is crushed by the wood crusher, the output size can be a diameter 3-5 mm which is suitable for further processing.

Tips: The maximum feed-inlet diameter of each model is AMS-400—50mm, AMS-600—100mm, AMS-800—150mm, AMS-1000—150mm

Wood Crusher Features and Application
1. Our wood crusher is composed of a machine body, knife chipping part, crushing part, and sieving part, etc. The advanced wood crusher combines both chipping and crushing in one machine, so there is no need to use a wood chipper for pre-processing of wood logs. The output of this machine is sawdust which can be further made as wood pellets.
2. Adopt Japan’s “NSK” bearing which can guarantee a long working life.
3. Wood crusher is safe, endurable, and efficient. Besides, it is highly eco-friendly and energy-saving.
4. Widely used in paper plants, particle board plants, fiber broad plants, etc.

Wood/Feed Hammer Mills
The hammer mill is another crushing machine for a complete pellet line. It is used to crush materials by the collision between the high-speed hammers and materials. The hammer mill is suitable for crushing raw material with sizes of less than 50mm (diameter). The output size can reach a diameter of 3-5 mm, both coarse and fine grinding is realized by adjusting the gap between hammers and screen then it is suitable for further processing. Simple construction, convenient operation, high efficiency, and low power consumption.
Wood/Feed Hammer mill Working principle
A hammer mill consists of delivery device, hammers, screen, rod, and rotor on which hammers are mounted. The hammers swing on the central rotor freely. The rotor spins at a high speed while the material is sent into a feed hopper. The material is impacted by the hammers and is thereby ground and then discharged through screens in a selected size.

Wood Hammer mill
Wood hammer mill is widely used for grinding biomass material like straw, grain stalks, wood chips, and tree branches to be powder of less than 3-5mm, which is the suitable size for making wood pellets.

Feed hammer mill
A hammer mill is also an ideal machine for grinding grains like husks, maize, wheat, beans, peanut, etc which can be made into feedstuff. The feed hammer mill is of tear circle design which ensures a larger space for the grinding chamber and improves working efficiency by 40%.
