Production line introduction :

The general production process of wood pellets: Log → Chipping → Drying → Crushing → Pelleting → Cooling and Screening → Packaging Zhengzhou E.P Machinery Co., Ltd. has rich experience in designing large-scale pellet production lines. It is a professional pellet machine manufacturer in design, manufacturing, installation, and after-sales service. E.P Machinery is available to provide you with a complete set of pellet production solutions, including wood chippers, dryers, hammer mill, pellet machines, cooling & screening machines, and packaging machines. E.P Machinery also can provides you customized production, installation, and commissioning services. Besides, we have also established a branch company in Malaysia. All our machines are exported to overseas markets and are welcomed by customers all over the world. The output of our wood pellet production line ranges from 900kg/h-3t/h and can process a variety of different raw materials. The pellets discharged are smooth, and the appearance of the pellets is perfect and beautiful. The following are the suitable raw materials for our wood pellet machine : Hardwood : oak, birch, beech, rubberwood, eucalyptus, pine, and other wood chips; Softwood:Agricultural waste (such as corn stalk, wheat stalk, cotton stalk...), chaff (rice husk, rice bran, peanut husk, bagasse, soybean stalk...); Others : waste paper, coconut shell, grass, palm shell, etc.

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.
