RD-420MX Biomass pellet mill 0.8-1.2T/h

RD420MX parameter specifications：

• This machine is suitable for small biomass pellet processing plants. The capacity is 0.8-1.2 ton per hour. This model of pellet mill is equipped with automatic lubrication system and die-hoisting device. This machine doesn’t need worker to add grease and operation and maintenance are very convenient.

• According to the characteristics of biomass raw materials, we have made a special design for the main gear & pinion shaft, and handed to a professional gear factory to complete the processing which makes the main gear & pinion shaft with high precision and long service life.

• 5 sets bearings in gearbox are FAG bearings imported from Germany; the main shaft and the combined quill shaft in gearbox are forged with 42CRMO materials whose strength and wear resistance are better than ordinary materials and is more durable; the main components and the gearbox are processed by high-precision CNC machine to ensure the high-precision cooperation of the components, greatly improve the service life of the machine.

• In response to the poor fluidity of various agricultural and forestry wastes, we have installed a force-feeding system in front of the pelletizing chamber, so that raw materials can easily enter the pelletizing chamber and be pressed. The feeding conveyor is also equipped with the arch breaking device and a variable frequency motor that can adjust the material flow speed, so that the material can enter the pelletizing chamber very smoothly.

• At the same time, in view of the characteristics of light gravity of biomass raw materials and more ash, we add a sealing device between the door cover and the pelletizing chamber, so that the dust is not easy to leak. The door cover and forced feeder are made of stainless steel to avoid the corrosion of hot steam during pelletizing. The door cover also adds a collection inlet device for hot steam in the pelletizing process, which can be extracted from the hot steam in the pelleting chamber by increasing the dehumidification device, greatly reducing the heat of the pelleting chamber. Thus prolong the service life of the roller bearing.

• All our pellet mills are equipped with safety devices. If there are small iron nails or too dry and wet raw materials in the pelletizing process, which makes pelleting very difficult, the machine will break the shear pin by itself and force the main motor to stop running to protect the

Working principle of wood pellet machine:

Sawdust pellet machine is a special equipment used to process sawdust into wood pellet fuel. Here's how it works:

• The sawdust granulator is mainly composed of a feeding system, a pressing system, a cooling system, a discharging system, a lubrication system, and a control system.

• Feeding system: The wood chips are conveyed to the inside of the pellet machine through the feeding port, and the wood chips are usually fed into the pellet machine with a conveyor or screw feeder.

• Pressing system: Wood chips are compressed into pellets through a mold or drum inside a pelletizing machine, and the wood chips are usually pressed into pellets by high pressure.

• Cooling system: Newly made wood chips are usually in a softened state due to high temperatures, so pellet machines are usually equipped with cooling systems to reduce the temperature of the pellets and prevent them from clumping again at high temperatures

• Discharge system: The cooled wood chips are discharged from the discharge port of the pelletizer and conveyed to the storage or packaging equipment.

• Lubrication system: The pellet machine may have certain wear and tear during operation, so a lubrication system is needed to ensure the normal operation of the pellet machine.

To set up a complete wood pellet plant to produce wood pellets, several key steps and equipment are involved:

• 1. Crushing equipment: The process starts with a wood chipper or crusher to break down raw materials such as logs, branches, or wood blocks into small wood chips.

• 2. Mixing equipment: The mixer is used to mix various raw materials to improve the calorific value of the fuel. Vertical and horizontal mixers can be used for this purpose.

• 3. Feeding equipment: The screw conveyor is essential to convey the material to the pelletizing equipment at a consistent speed, ensuring the smooth operation of the pelletizer.

• 4. Pellet Machine: Wood pellet machine is the core equipment of small wood pellet plant. It compresses the material into particles. Depending on the power and capacity requirements, a variety of models are available.

• 5. Cooling: After granulation, the pellets need to be cooled to room temperature. This can be achieved by free cooling in the storage bin or by using a counter-flow cooler to speed up the cooling.

• 6. Packing: After the pellets are cooled, they can be packed. Packaging can be done in small bags (20-50kg) or bulk bags for large batch packaging.

  By following these steps and utilizing the appropriate equipment, such as crushers, mixers, pellet mills, coolers, and packaging machines, a complete wood pellet plant can efficiently produce wood pellets for various applications.

Which is better, ring die granulator or die pelletizer?

Ring die granulator and flat die pelletizer are commonly used equipment in the manufacturing process of biomass pellets such as sawdust pellets. Each of them has different characteristics and scope of application, and it is impossible to generalize which one is better, but to choose according to the specific situation. Due to its structure and working principle, the ring die granulator can produce higher quality pellets with a wider range of applications, making it more suitable for various raw materials. It has a higher pressure and temperature in the production process, which can better compress the raw materials into pellets. This equipment is suitable for commercial production of large biomass pellet manufacturers. Comparatively speaking, flat die granulators are more suitable for small-scale production or home use. It has a small production capacity and relatively low requirements for raw materials, making it suitable for small-scale household biomass pellet processing and manufacturing. Therefore, which one is better to choose needs to be comprehensively considered according to the production scale, raw material characteristics, cost and production requirements.

Types of wood pellet machine molds:

The types of sawdust pellet machine molds are mainly classified according to hole depth, hole spacing, hole width, and mold material:

• Classification according to hole depth: The hole depth of the mold generally has two types: shallow hole mold and deep hole mold, which is suitable for the production of different particle requirements.

• Classification according to hole spacing: the hole spacing of the mold will affect the density and shape of the particles, and there are generally two kinds of fixed hole spacing molds and adjustable hole spacing molds.

• Classification by hole width: The hole width of the mold also affects the size and shape of the particles, including coarse and fine molds.

• Classification according to mold material: mold material can be divided into alloy steel mold, stainless steel mold, carbon steel mold, etc. Different materials have different wear and corrosion resistance, which are suitable for different production environments and needs.

Rongda granule products:

A good biomass pellet should have the following characteristics:

• High calorific value: The calorific value of biomass pellets is an important indicator of their quality, and high calorific value means that more heat energy can be released per unit mass of pellets and improve combustion efficiency.

• Low ash content: The lower the ash content, the less impurities contained in the particles, and the amount of ash produced after combustion will also be reduced, which is conducive to clean combustion.

• Low moisture content: The water content of biomass pellets has a significant impact on their combustion performance, and low water content pellets are easier to burn and release heat energy.

• Proper particle density: Moderate particle density can guarantee the stability and convenience of particles during storage and transportation.

• After proper compression: Compressing biomass pellets with a suitable pelletizer can improve their density, strength, and water resistance.

The following are the general requirements for some common biomass pellet parameter indicators:

• Ash content: generally less than 1%-3%.

• Moisture content: generally less than 10%-12%.

• Calorific value: generally required to be greater than 4000-4500 kcal/kg.
