Diesel Engine Flat Die Biomass Pellet Machine

An ideal solution for small-scale and mobile biomass pellet production, especially in areas without a stable electricity supply

The diesel engine flat die biomass pellet machine is a compact, portable pelletizing unit powered by a diesel engine. It’s designed for converting biomass materials like sawdust, crop straw, and wood shavings into biomass pellets for burning or animal bedding. We supply several models of diesel engine biomass pellet machines with capacities ranging from 50 kg/h to 500 kg/h. With its off-grid capability and simple structure, it’s especially suited for farms, rural areas, and field operations. We also supply electric flat die biomass pellet machines for use in areas with sufficient electricity.

Start to Make Your Biopellets
This small pellet machine with a diesel engine is an entry-level pellet machine that helps you start making biomass pellets for your home use or to sell to your neighborhood. Help yourself to be free from your backyard: leaves, hay, grasses, and sawdust are just the beginning. Whatever type of biopellets you want to make, this portable diesel flat die wood pellet mill is a suitable solution. You can also use this pellet machine to make feed pellets for horses, rabbits, goats, and fish. Make bedding pellets for animal stalls from cardboard

Versatile, mobile, and off-grid pellet production solution

1. Biomass Fuel Production
Purpose: Produces eco-friendly fuel pellets for heating or cooking
Pellet types: Wood pellets, straw pellets, rice husk pellets, peanut shell pellets, and other agricultural waste pellets
2. Animal Feed Pellet Production
Purpose: Converts raw feed materials into compact, nutritious feed pellets. Most used in small-scale poultry, fish, and livestock farms.
Feed materials: Corn, wheat bran, soybean meal, grass, alfalfa, etc.
3. Agricultural Waste Recycling
Purpose: Turns waste biomass into usable products to add value to agricultural by-products and support the circular economy in farming communities.
Raw materials: Crop stalks, cotton stalks, corn cobs, bagasse, rice husks
4. Off-Grid Pellet Production
Best suited for: Remote areas without stable electricity. Forest regions. On-site field work and mobile biomass processing
5. Small-Scale Commercial Pellet Production
Users: Entrepreneurs, cooperatives, local pellet sellers
Advantage: Start a pellet business with low investment and no need for electric infrastructure
6. Experimental and Training Use
Used in: Agricultural institutes for biomass energy training. Demonstration projects for renewable energy education. Pilot-scale testing of new biomass material formulations

• Portable and Mobile – Equipped with wheels (optional) for easy transportation.
• Various Output Models – Production capacities range from 50 kg/h to 500 kg/h.
• Adjustable Die and Roller – Can produce pellets of different diameters (from 2-12 mm, usually 6mm, 8mm) by changing the die mould.

1. Raw Material Feeding: Sawdust or biomass powder is fed into the hopper.
2. Compression: The material is pressed between a rotating roller and a flat die by the diesel engine’s power.
3. Pellet Formation: Under high pressure and temperature, the material is extruded through die holes and forms cylindrical pellets.
4. Pellet Cutting and Discharge: A cutter trims the pellets to the desired length before they are discharged.
