Component of charcoal extruder machine


The spiral of the charcoal briquetting machine is composed of three sections, and the front section can be inserted into a stick to control whether the finished product is hollow or solid. When replacing the screw, only the front part is replaced.

There are various shapes of model dies for charcoal briquette machine, which can extrude different shapes of charcoal briquettes.

Reducer of charcoal briquette machine

The charcoal briquette machine uses a hard tooth surface reducer, which is small in size and has a strong bearing capacity.

Working principle of coal press machine

The charcoal briquette machine makes powdered raw coal into different shapes. Its working principle is: the electric motor transmits the power to the transmission through the belt pulley to drive the propulsion shaft to work, and the screw propeller on the propulsion shaft pushes the coal material and pushes it through the forming die to produce an ideal high-pressure coal stick.

Operation precautions of charcoal extruder machine

No matter how superior the performance and quality of the coal briquette machine is, all machines need to be maintained after a period of use. Only in this way can the service life of your charcoal briquette machine be extended. The precaution of charcaol briquette machine is also important.

  • Before starting the charcoal extruder, check whether the rotating parts are flexible and whether there is any abnormal noise. The empty machine can be put into production after 2 to 3 minutes.
  • The raw materials must be processed, the maximum particle size is less than 3mm, add water, add binder, curing agent, stir and then stand for 24 hours before use.
  • If the feed opening is blocked, use wooden or bamboo strips to clear it. Metal rods are forbidden.
  • The bearings of the rotating parts of the charcoal briquette machine should be filled with lubricating oil regularly, and the temperature of the bearing parts should not exceed 60℃.
  • When preparing to stop the charcoal briquette machine, stop unloading first, and stop the machine after the material in the cylinder is emptied, disassemble the machine head, and reinstall it after cleaning.

Charcoal briquette cutting machine

The video shows the three different briquette cutter of the charcoal briquette machine, they can cut the briquette into different shapes.

Automatic cutter

This kind of cutting knife is controlled by an infrared sensor probe, and the cutting length can be adjusted according to actual needs. The commonly used diameter is 10-12cm. The shortest diameter is 5cm.

Multifunctional charcoal cutter machine

This cutter adopts CNC numerical control system, and its length range is very wide, ranging from 3-40cm, the shortest can be 2.5cm. This cutter is not easily affected by the environment, strong light, and dust during the cutting process, and the finished product has a stable effect. Its small size saves space during transportation.

Cubic charcoal briquettes cutting machine

The coal cut by this cutter is a square cube with an edge length of 2.5 cm. It is mainly composed of hob and baffle. The standard configuration is a 1.5-meter conveyor belt, and the length of the conveyor belt can be customized.

Evaluation standard of charcoal briquette quality

In order to ensure that the coal or charcoal rods made by users are of high quality, WOOD machinery will introduce you to the quality measurement standards of coal press machines. Such as charcoal briquette appearance and using effect of the briquette. More than that, we will teach you from which aspects to improve the quality of the products.

How to make high-quality coal briquettes?

The quality of the finished coal briquettes affects the price and durability. As a user of a coal press machine, everyone wants to improve product quality. So is there any methods to improve the quality of coal sticks? Sure there is. One of the most important factors is the size of raw materials. Ensure that the size of the pulverized coal powder is less than 8mm, and the charcoal powder is less than 1mm.

Differences between sawdust briquette machine

Because of the similar outlook and name, some customers are always confused about them. WOOD machinery will introduce the differences between a sawdust briquette machine and a charcoal briquette making machine.

Raw materials

The sawdust briquette machine copes with small wooden or biomass chips, like sawdust, rice husk and bamboo chips, which size is 3mm to 5mm. The raw material can also be logs or large branches, then they will be crushed by a drum wood chipper or wood hammer mill first. However, the raw materials of charcoal briquette should be coal powder, which has been mixed with water and adhesive in advance.

Working principle

The sawdust briquette machine makes biomass stick by high temperature and pressure. At the end of the die head, there are three heating circle devices to heat the biomass stick. The coal pressing machine has no heating device. The density of the pulverized coal is increased by spiral rotation and extrusion, and the pulverized coal is formed through a die.


There are some pictures you can see below. It is very obvious that products made by sawdust briquette machines are yellow wooden sticks, meanwhile, products made by charcoal extruders are black coal sticks.

The sales of WOOD machinery charcoal extruder machine continue to maintain a momentum of growth. Investigating the reasons for this, the industry expert gave us the following analysis, which can explain why charcoal extruder machine are so popular. To begin with, there are many types of raw materials fit to the charcoal briquette machine. Such as charcoal powder, coal powder and grass powder.

Secondly, the price of the charcoal extruder is not high, the small invest can make a big profit. Last but not least, The density of bar charcoal is more than 3 times that of ordinary log charcoal, it burns without smoke, has a calorific value of 5500-7000 kcal/kg, and has low ash content. Because of the above features, the market application range of charcoal rods is very wide.

Common mechanical failures and solutions of charcoal briquette machine

Any machine will have various problems during use, and we also have corresponding measures for them. When it comes to a coal press machine, after using the machine for a period of time, the staff should check the bearings. The bearing of the coal rod machine is damaged or does not operate normally, which will increase the load of the motor, and it is easy to burn out the motor for a long time.

As a solution, the factory should check the bearings of the coal rod machine on time to see if there is any damage, and the old parts should be replaced in time to avoid affecting the normal operation of the machine.

How to prolong the service life of charcoal extruder machine?

All machines need to be maintained after a period of use, no matter how superior the performance and quality of the coal press machine are. Only in this way can the service life of your machines be extended, and the quality of the coal sticks produced can be ensured. There is some advice to prolong the service life of a charcoal extruder. Including maintaining the feeding part of the machine and maintaining the bearings of the various parts of coal briquettes.
