Hammer Mill→Airflow Dryer→Sawdust Pellet Machine→Cooling & Screening Machine→Packaging Machine
Zhengzhou E.P Machinery Co., Ltd. is a machinery manufacturing company in the production and trading business and has rich experience in designing and manufacturing pellet production lines. Our factory can produce all the equipment related to the wood pellet production line, which includes hammer mills, airflow dryers, flat die wood pellet machines, cooling & screening machine, and packaging machine. Our company not only provides evaluation, customization, installation, and commissioning services but also a very complete after-sales service to ensure that the wood pellet production line achieves the highest production efficiency and customers can get the best economic benefits.

Applicable raw materials:

Our company's pellet production line can process a variety of biomass materials. You can choose the most economical raw materials according to the application and price. The following are suitable feeding raw materials.
Wood:Wood (such as rubber trees, pine, eucalyptus, willow, acacia), sawdust, wood shavings, and wood chips;
Agricultural waste : husk (such as rice husk, rice bran, wheat husk, etc.), straw (such as corn stalk, wheat stalk, canola stalk, cotton stalk, etc.), bagasse, peanut husk, pineapple peel, reed, soybean stalk, etc.
Others : coconut shell, palm fiber, palm kernel shell (PKS), waste paper, grass (such as alfalfa, king grass, elephant grass), moso bamboo, and other biomass waste.

Cooling & Screening Machine

The cooling & screening machine uses the method of countercurrent cooling to cool high-temperature and high-humidity wood pellets. The cold air passes through the material directly, and touches with the cold pellets at first, and is gradually heated and touches with the hot pellets again. The direction of the air flow is opposite to the direction of the pellets flow, so that the pellets are gradually cooled in the forward direction, which can avoid the pellet surface cracking caused by the direct touch of the cold air and the high-temperature pellets in other coolers, thereby causing the pellets to be cracked. This cooling & screening machine has large production, good cooling performance, high automatic, low noise, and less maintenance, making it the preferred model for many customers.


1. The temperature of the cooled pellets won’t be higher than +3-+5 of the room temperature; precipitation = 3.5%;

2. It has the special function of automatic pellet discharging when the machine stops working, and the discharge is smooth and the operation is stable;

3. Special pellet discharge method to achieve smooth discharge;

4. Uniform cooling performance and low proportion of breaking;

5. Simple structure, low operating cost, and small space occupation.
