Rongda Biomass Pellet Machine: Flat Die vs Ring Die Types & Technical Features

Rongda Biomass Pellet Machine: Flat Die vs Ring Die Types & Technical Features

Rongda biomass pellet machine types

Biomass pellet machine is a professional equipment that converts biomass raw materials into high-density solid pellet fuel. According to the different mold types, biomass pellet machines are mainly divided into two types: flat die biomass pellet machines and ring die biomass pellet machines. As a professional biomass pellet machine manufacturer, Rongda Machinery provides various models of equipment to meet different customer needs.

Application Range

Rongda biomass pellet machines can process various biomass raw materials:

Agricultural Waste: Straw, rice husk, peanut shell

Wood Raw Materials: Wood chips, furniture factory waste, branches, tree roots, demolition materials, etc.

Other Biomass: Various wood materials

Flat Die Biomass Pellet Machine

Components

Motor, Drive Shaft, Reducer, Vertical Shaft, Flat Die, Pressure Rollers, Feed Hopper, Discharge Hopper

Working Principle

During operation, materials directly fall into the working area between the pressure rollers and the die from the feed port. The large nut on the main shaft is adjusted to achieve the effect of tightening the pressure rollers. Cylindrical solid pellets are continuously formed at the bottom of the flat die template. The pellets continue to elongate until they are cut by the cutter assembled on the main shaft to reach the required length, and then centrifugally thrown out to the discharge port by the rotating disk of the main shaft. This completes the pellet pressing process.

Technical Features

Simple Structure: Small footprint, simple operation, low noise

Flat Die Design: The die is flat, with two or more pressure rollers

Balanced Force: Adopts central direct compression structure, two pressure rollers evenly force on the flat template, ensuring balanced and effective pressing force

Heavy-Duty Design: Equipped with heavy-duty industrial reducer, stronger load resistance, effectively improving equipment service life

Wear-Resistant Components: Roller and flat die template components use high-quality high-wear-resistant alloy steel, through strict heat treatment and carburizing, improving service life

Application Scenarios

Small-scale production below 1 ton per hour

Home or small farm use

Experimental production or small-scale processing

Ring Die Biomass Pellet Machine

Components

Vertical Motor, Ground-Type Gearbox, Bearing Chamber, Die, Pressure Rollers, Slewing Bearing, Oil Filling Machine, Lubrication Pump, Cooling Machine

Working Principle

During operation, materials fall vertically on the main shaft frame plate from the feed port. Through the rotation of the frame plate, materials are evenly distributed around the die. Under the rolling of the pressure rollers, biomass materials pass through the customized round holes of the die. Under the strong extrusion of the pressure rollers, biomass materials produce physical changes, promoting biomass materials to bond, and form continuously elongating cylindrical solid pellets. The pellets continue to elongate until they are cut by the cutter assembled on the independent slewing bearing to reach the required length, and then scraped to the discharge port by the scraper assembled on the slewing bearing. This completes the pellet pressing process.

Technical Features

Vertical Feeding: Materials directly fall into the pressing chamber, one-word feeding method, avoiding material jamming

Uniform Distribution: The die is stationary, the pressure roller rotates, materials fall on the main shaft, separate materials through main shaft rotation, destroy their agglomeration properties, materials evenly enter the working chamber

Die Design: Two-layer die design, increasing service life, after one layer is worn out, reverse use, saving costs

Heat Dissipation Design: Ring die, vertical structure is conducive to heat dissipation and cooling of the pelletizing chamber, accompanied by dust removal fan, driving air flow

Independent Discharge: Independent discharge device, main shaft and discharge system do not interfere, ensuring pellet forming rate

Automatic Lubrication: Automatic oiling system, bearing chamber and gearbox are automatically lubricated by oil pump, for rotating pressure rollers, rotating material dial, and can automatically adjust oiling time

Application Scenarios

Large-scale production above 1 ton per hour

Industrial-grade production needs

Continuous production scenarios
