Biomass straw/rice husk/peanut shell/sawdust wood powder wood shavings pellet machine/pelletizer/granulator/vertical ring die pellet mill

I. Main Performance and Features:

1. Adopts the latest design with a specialized square high-efficiency motor for pellet mills, saving approximately 10% energy consumption under the same power.

2. Utilizes a dedicated gearbox more suitable for the pellet-making industry, featuring parallel hard-toothed surfaces, stronger impact resistance, and more powerful horsepower.

3. The oil lubrication system is meticulously designed with two optional solutions: Solution 1: Grease-free, pure thin oil lubrication with circulating oil flow, excellent cooling effect, and more conducive to extending bearing life. Solution 2: Grease lubrication for pressure wheels, special structure without oil seals, eliminating easily damaged fluoroelastomer oil seals. The pressure wheel lining can be used until natural wear without damaging the bearings.

4. Feeding uses a current control system, automatically regulating feeding speed based on current size, ensuring reliable feeding without clogging, saving labor, and significantly reducing costs.

5. The feed inlet and material distribution system adopt a quick-disassembly structure, making mold and roller replacement more convenient and time-saving.

II. PK Flat Die Pellet Mill, Several Advantages

1. Vertical Ring Die Pellet Mill: The mold is stationary, pressure wheels rotate, vertical feeding ensures more direct and smoother material intake.

Old Flat Die Pellet Mill: The mold rotates, pressure wheels are stationary, vertical feeding is direct, but due to mold rotation, formed pellets undergo secondary beating, resulting in poor pellet formation.

New Flat Die Wood Pellet Mill: The mold is stationary, pressure wheels rotate, vertical feeding is equally direct and smooth, making it suitable for soft and fluffy biomass materials. However, due to flat die structure limitations, mold diameter cannot be large, so it only appears in small models to meet small customer needs.

2. Vertical Ring Die Pellet Mill: Vertical structure, ring-shaped mold, more conducive to heat dissipation and cooling.

Flat Die Pellet Mill: Material covers the flat mold above, with hot finished pellets below, making the compression chamber relatively enclosed. Heat dissipation is poor,不利于轴承的使用寿命以及易损件的磨损周期。

3. Vertical Ring Die Pellet Mill: Double-layer mold design allows one mold for multiple uses or dual purposes, reducing costs and increasing efficiency.

Flat Die Pellet Mill: Only single-piece design is possible.

4. Vertical Ring Die Pellet Mill: Independent discharge system does not affect pellet production.

Flat Die Pellet Mill: Uses main power to discharge, rotation speed is too fast, pellets are拨动 at high speed while still hot, easily damaging finished pellets.

III. PK Horizontal Ring Die Pellet Mill, Several Advantages

1. Vertical Ring Die Pellet Mill: The mold is stationary, pressure wheels rotate, vertical feeding ensures more direct and smoother material intake.

Horizontal Ring Die Pellet Mill: Pressure wheels are stationary, mold rotates. This forces side feeding only, and stationary pressure wheels hinder smooth feeding of fluffy biomass materials,容易在压轮架板处堆积蓬料，造成进料不通畅。

2. Vertical Ring Die Pellet Mill: Feeding is smooth and direct, discharge is stable.

Horizontal Ring Die Pellet Mill: Feeding requires assisted pushing, discharge involves mold throwing, pellets are unstable and easily broken.

3. Vertical Ring Die Pellet Mill: Gearbox is specifically designed for difficult-to-press and bond biomass materials, with excellent shock and fatigue resistance.

Horizontal Ring Die Pellet Mill: Gearbox structure is similar to automotive rear axle differentials, not heavy-duty,不太适合物料嘈杂的颗粒制作行业。

4. Vertical Ring Die Pellet Mill: High and stable output, better pellet quality.

Horizontal Ring Die Pellet Mill: Low and unstable output, poorer pellet quality.

IV. Scope of Application

This product is suitable for pressing materials that are difficult to bond and form. Such as: rice husks, sunflower seed shells, peanut shells, various fruit shells; branches, logs, bark, various wood scraps; various crop straws, such as wheat straw, corn straw, reed straw, rice straw, cotton stalks, etc.; rubber, cement, ash, various chemical raw materials. Applied in feed mills, wood processing plants, fuel plants, fertilizer plants, chemical plants, etc., it is an ideal biomass compression forming equipment with small investment, quick results, and no risk.
