Sawdust Briquette Machine | Briquettes Making Machine for Rice Husk & Wood Powder
The industrial sawdust briquette machine is also known as the wood briquettes making machine and pini kay extruder machine. This biomass briquettes machine is mainly used to extrude rice husks, sawdust, and wood powder into solid rods under higher density under high temperature and high-pressure conditions.
The sawdust briquette machine adopts electric heating, which can pyrolyze the lignin in the raw materials so that the raw materials such as rice husk or sawdust can be bonded together. In addition, the screw propeller inside the briquettes extruder machine can extrude the sawdust from the molding die to produce solid biomass rods of various shapes. The produced biomass briquettes can usually be used directly as fuels, or they can be reprocessed to make charcoal products.
Raw materials for processing sawdust briquettes
Sawdust, crop straw powder(corn stalk, soybean stalk, sorghum stalk, cotton stalk, rape stalk, peanut seedling, sunflower stalk), rice husks, grass, shrub branches, bamboo and wood cutting head, material head, bagasse, coconut shell powder, bamboo powder, palm kernel shell powder, etc. Almost all wood waste materials and farmland straws can be used to process sawdust briquettes. But these raw materials need to be pre-processed first, such as crushing and drying, before they can be processed by the sawdust briquettes maker.
Features of the raw materials for briquetting
- Raw materials such as branches and straws need to be crushed by the sawdust crusher machine. The fineness of sawdust cannot exceed 8mm. The size commonly used by users is 5mm.
- The humidity of sawdust or rice husk needs to be controlled at about 8%-12%. If the humidity is too high, we can use a sawdust dryer machine for rapid drying.
Sawdust briquette machine description
The sawdust briquette machine is usually used in the charcoal production line. The biomass materials for briquetting by the sawdust briquette extruder machine should be crushed by the wood crusher first, like bamboo, wood branches, fruit shell, straw (including paddy straw and wheat straw), corn stalk, cotton stem, and so on. These biomass materials' diameter should less than 5mm. And then these biomass materials should be dried by the airflow dryer or rotary dryer to reduce their moisture content below 12%. In the end, the sawdust briquettes making machine can extrude the biomass powder into biomass briquettes(pini kay)without any binder.
Sawdust briquette machine can extrude the loose raw materials into solid biomass bars with central holes (generally 4-angle and hexagonal bars) through a series of processes of the screw propeller, heating ring, forming a cylinder and cone sleeve, and through high temperature and high-pressure process, to prepare for the next step of carbonization. This pini kay making machine has advantages of high quality, small size, and good flammability. Most of the general products are in the shape of four or six angles cylinders with 48, 50, and 80 mm outer diameter. The utility model can also be made into spherical, granular, and honeycomb briquettes so that it can meet different clients’ needs.

How to install and testing the sawdust briquette maker machine?
In the charcoal production line, this biomass briquette machine is an important piece of equipment for making pini-kay(sawdust briquettes) which can also be named as sawdust briquettes or charcoal briquettes. Only the high-quality pini-kay can be further carbonized into charcoal.
Therefore, it is vital to master the knowledge of how to install and debug the sawdust briquette machine. The following is useful guidance to help you.
How to install and debug the sawdust briquettes machine?
It is not difficult for you to do the installation and debugging if you followed these instructions step by step as below. Do as the instructions told in order so you can ensure the safe production of pini-kay and charcoal.

How to determine the motor power of pini kay briquettes extruder machine?
Different types of pini kay briquettes extruder machines have different motor powers, and correspondingly, their output is also different. The motor power of the common sawdust briquette machine is 15kw, 18.5kw, and 22kw.
Customers can choose the corresponding machine model according to their own output requirements. We can also customize suitable motors for customers according to their production needs.
To use a sawdust briquette machine to make high-quality biomass briquettes, it is necessary to master the temperature control method. If the temperature is not well controlled, the color, density, and shape of the finished briquettes may not be ideal.
When using sawdust briquettes extruder machine, we need to start the heating function of the machine in advance and preheat the temperature of its heating ring to about 200℃. Then gradually add sawdust or rice husk to the feed port of the machine.
Observe the color and molding effect of the briquettes made from the discharge port. If there are many cracks on the surface of briquettes, or the color is light brown, the heating temperature is too low, and the heating ring needs to be heated to about 280°C.
If the color of the made briquettes is brown-black, it means that the temperature is too high, and the temperature cannot be continued at this time, but the production of materials should be continued, and the temperature of the belt will naturally decrease to a suitable temperature.
Connection method of heating ring for biomass briquette machine
The heating ring of the biomass briquette machine is the main part of forming materials such as sawdust and rice husk. However, after long-term use, the heating ring and its wires will be damaged.
Therefore, the user needs to replace and rewire the heating ring of the briquette machine. The wiring of the heating coil needs to follow a certain wiring method. If the wrong wire is connected, it will not be used.
What will affect the production efficiency of pini kay briquette maker?
When using a commercial pini kay briquette machine to make briquettes, you must pay attention to the control of the humidity of the raw materials, the control of the heating temperature, and the degree of wear of the machine's accessories.
Only by paying attention to the control of these influencing factors can the production efficiency of the sawdust briquettes extruder machine be improved.
