Empty Fruit Bunch Pellet Mill

Brief Introduction

The empty fruit bunch (EFB) pellet mill is a biomass ring die pelleting equipment specifically developed for palm waste materials such as EFB, which are high in fiber, high in moisture, and have strong toughness. Palm hollow fruit bunch raw materials have long fibers and contain many impurities, making ordinary pellet mills prone to die clogging. The palm hollow fruit bunch pellet mill features a specially optimized ring die and pressure roller structure, which can extrude pre-treated palm hollow fruit bunches into high-density biomass pellets. The mill has a strong load-bearing capacity, supports long-term continuous production, and produces dense palm hollow fruit bunch pellets that are not easily broken, facilitating storage and long-distance transportation. It is a core piece of equipment for the resource-based treatment of EFB waste in palm processing plants and is also compatible with pelleting various agricultural and forestry biomass raw materials.

Working Principle

After being crushed, impurity removed, and pre-treated with moisture, the hollow palm fruit bunches are fed into the pelletizing chamber of the palm hollow fruit bunch pelletizer. The main shaft of the equipment drives the ring die to rotate, and the pressure roller rotates synchronously with the friction of the material, forcefully squeezing the palm hollow fruit bunch material into the die hole of the ring die. The material is compressed and shaped within the die hole; after continuous extrusion, the material is cut by the cavity cutter to form cylindrical pellets of a fixed size. The newly formed pellets are at a high temperature, and after subsequent cooling and screening, the hardness of the pellets is increased, and powder is removed, completing the production of palm hollow fruit bunch pellets.

Parameter

Suitable Raw Materials

Main raw material: Empty fruit bunches of palm (EFB); Compatible raw materials: Palm shells, sawdust, straw, rice husks, sunflower seed shells, corn cobs, and other agricultural and forestry biomass waste. Raw materials must be pre-crushed and their moisture content controlled to a suitable range.

Application Areas

1. Biomass Fuel Industry: Hollow palm fruit clusters serve as clean fuel in heating boilers and biomass power plants, replacing fossil fuels and reducing carbon emissions.

2. Resource Utilization of Palm Oil Factory Waste: Palm oil processing plants process hollow palm fruit clusters on-site, turning waste into treasure and solving the problems of waste accumulation and rotting pollution.

3. Organic Fertilizer Substrate: Hollow palm fruit clusters can be used as a substrate for organic fertilizer fermentation, for soil improvement, and as a horticultural cultivation substrate.

4. Livestock Bedding: After harmless treatment, hollow palm fruit clusters can be used as bedding for livestock and poultry.

Details

1. HUIXIN Gearbox: Heavy-duty HUIXIN gearbox supplies stable high torque to handle the drag resistance of long, interwoven palm EFB fibers.

2. Rotating bracket: Reinforced rotating bracket dampens vibration caused by uneven, low-density palm fiber feeding flow.

3. Reducer: Precision matched reducer maintains reliable power transmission under variable loads from stringy empty fruit bunch feedstock.

4. 304 stainless steel dust cover: 304 stainless steel dust enclosure resists corrosion from acidic palm fiber ash and abrasive palm dust.

5. Internal lifting knife: Built-in internal lifting knife slices tangled palm fiber masses and stops matting and bridging inside the pelletizing cavity.

6. Adjustable blades: Adjustable blades tune feed layer thickness to suit the fluffy, fibrous and stringy physical properties of processed EFB.

Unique Advantages

1. Mill assembly: Tailored ring die and roller clearance designed for long palm fibers, drastically reducing fiber winding and die clogging frequency.

2. HUIXIN gearbox: Purpose-calibrated HUIXIN gearbox with shock-resistant gear structure, performing far better under unstable palm fiber loads than ordinary gearboxes.

3. Stainless dust cover: One-piece 304 stainless dust shield replaces regular painted steel, resisting continuous scouring and acid corrosion from palm ash dust.

4. Bottom feeding reducer: Refined under-feed reducer prevents tangled EFB fibers from wrapping and forming arches that block the feed chute.

5. Cooling system: Multi-channel balanced air cooling setup removes residual heat evenly, reducing pellet splitting caused by uneven thermal shrinkage of palm fiber pellets.
