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 cylinder 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.

Structure of wood sawdust briquette machine
♦ Motor. The motor power of the briquettes making machine varies according to different models, generally between 18.5-22kw. The motors used in our factory are all copper core motors with sufficient power and long service life.
♦ Feeding inlet. The feed port of the machine can be added with an extended funnel, which is convenient for feeding and using. The screw inside the feed inlet can push the material forward.
♦ Belt pulley. When working, the motor will drive the belt pulley to run, so that to push the raw materials forward.
♦ PLC controller. When using large models of machines, we usually equip this electric control cabinet. Especially when the machine is used in the charcoal production line, the electric control cabinet can ensure the safe use of electricity.
♦ Heating part. The heating ring is usually sleeved on the outside of the forming cylinder. These heating coils are vulnerable parts. When customers purchase the equipment, they usually purchase many heating coils for spare use.
♦ Extruding molds. The extrusion molding part of the machine is mainly determined by the molding cylinder. The forming cylinder can be replaced with different shapes and different diameters.

When this machine is working, under the driving of the motor, the inner screw propeller will push the materials into the molding tube smoothly with high temperature and high pressure, and the finished pini-kay can be produced out at a steady speed. The spare parts are made of wear-resistant materials in the sawdust briquette machine so that it has high working efficiency and long service life. The normal size of the wood rod is 50mm or 48mm hollow rod. The product has the advantages of high density, small size, and good flammability, and can replace firewood and coal burning. General product outer diameter is 50-60mm, the aperture is 15-20mm, hollow hexagonal, octagonal, or circular.
Rice husk briquettes making machine features
- Rice husk briquettes making machine with reasonable design, reliable quality, simple structure, comprehensive function and labor-saving, which has strong applicability, all kinds of materials can easily be molded into the bar.
- The machine adopts the automatic electronic temperature control system, which can adjust the molding temperature at random and intuitively understands the working state of the equipment. Improved molding rate and working efficiency.
- The screw propeller of the sawdust briquettes extruder machine is made of 35cr high-quality steel, and after heat treatment, it has high hardness, toughness, and abrasion resistance.
- The forming cylinder of the sawdust briquette machine is made of high wear-resisting steel composite, with high toughness and hardness. Working life is much higher than the products of the same industry.
- It adopts a 15kw motor, which guarantees the stability of the equipment (11kw is the most commonly used motor in the market, and the molding rate is very low, and it is easy to burn out due to overload).

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.
- Keep the sawdust briquette machine steady in the horizontal direction and tighten all the connection bolts, especially the four bolts of the horizontal fixed molding cylinder, connect the electrical appliances and power lines.
- Check whether or not the bearing parts of the machine have been added lubricating oil, if not, we must carry on the appropriate lubrication.
- Check whether the power supply voltage of the sawdust briquette machine is normal. Make sure the fuselage is well-grounded. In addition, it is strictly prohibited that people standing in front of the forming barrel of the machine during the test.
- Make the machine run in the positive and negative directions for 5 minutes respectively under no load, and then observe whether the propeller operates flexibly in the positive and reverse direction and whether there are no obvious abnormal phenomena such as shaft sticking and friction (it is normal if there is slight friction sound). If there is no abnormality, normal production can be carried out. When any abnormality is found in the testing, it shall be stopped immediately to find out the reason, and then the no-load operation shall be carried out after troubleshooting.
- Adjust the temperature control instrument of the sawdust briquette machine to the required temperature (300 ℃ — 380 ℃). When the temperature reaches the preset temperature, then stop heating, and the red indicator on the temperature controller will light up, which indicating the completion of heating.
