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.

Hot Air Dryer

The hot air dryer is to mix the wet raw materials with the high-temperature airflow, and finally separate the water from the raw materials through the separator. It is widely used for drying wood chips, rice husks, corn stalks, etc. It is mainly composed of air blast stove, spiral feeder, buffer bin, air duct, cyclone dust collector, etc. The wet material and the heated air enter the dryer through the conveyor at the same time. The loose powder or granular materials are dispersed and suspended in the hot air. They are fully mixed, and the moisture is instantly removed during the entrainment process of the airflow. Our airflow dryer can reduce moisture from 40-45% to 8-12%. After passing through the drying pipe, the air and the solid mixture is firstly recovered by the cyclone separator, and then the light powder is separated by the bag filter, and the exhaust gas is evacuated by the induced draft fan.


1. Low cost and good drying performance;

2. Low energy consumption, low noise, easy to install and maintain;

3. Simple structure, small area, easy to build and maintain;

4. High drying strength, high drying efficiency, and large processing capacity;

5. Various heating source options. Users can choose electric heating, coal heating, gas heating, etc. according to their own conditions.
