There are several types of briquette machines with different working principles, they work on different pressures and suitable for different materials. So how they workdifferently? What are there advantage and disadvantages? Lets follow the article.
A briquette machine is used to turn the waste powder to a regular shape block, which can help to improve the conditions for those powder, make them easy for transportation, storage, and more useful for further usage.
Briquetting work always work with the binder as it needs the binding effect to get enough strength for the finished briquette. Biomass and industrialwaste are different from each other due to their binder sources.
The heating system is a special design for those briquettersdeal with materials contain lignin, lignin alway can be found on biomass. So theheating system is usually used for biomass briquetting. Other materials like coal, charcoal, etc. Binders are always needed when briquetting with the screw type briquette machine.
The suitablematerial is fed to the hopper and then conveyed by the screw inside the briquette machine.the rotating screw takes the material from the feed port, and compacts it against a die which assists the build-up of a pressure gradient along the screw.
As the screw briquette machine works with a pressure not that high, binders are always needed forming the briquette. Equip with a heating system will help the biomass material melt the internal lignin and turn it to a high-performance binder. Besides, other materials also work with this briquetterlike coal, charcoal, etc. These materials should be well mixed with the binder to get the briquette forms.
The briquette working process is in a chamber where materials are fed into, there materials are briquetting under a very high pressure. It causes theirplasticity and makes them binding stably together as a block.
Hydraulic type takes a long pressure keeping time on the briquette, this prevents theshort-time material deformation rebound and will cause a special heating for those materials like sawdust for melting its internal lignin, make the briquette with higher strength.
The piston type uses the rotary power of the mechanical device or the thrust of the hydraulic cylinder to reciprocate the piston (or the plunger), and the piston (or plunger) drives the ram to reciprocate in the forming sleeve to generate a pressing force to form the material to briquette.
A big pressure will be generated as the movement of the flywheel and punch the briquette time after time in a short time, it raises the temperature of the raw material. As the raw material moves, it fractionates with the inside, another kind of heat friction heat generates. With the action of these two kinds of heat, material raises its own temperature to a high level and melt the lignin. Particle materials then bind together and become strong enough.
Roller press works with two close rotating rollers at the same speed butwith opposite direction. The two rollers, with the same width and diameter, have holes on the surface. When they move, the same two holes on the different roller will coincide at the intersection of the midline and the briquette will be pressed there.
A normal roller press will use a wedge iron to fix the movable roller as it works on a low pressure. The hydraulic pump station is also can be used to fix the roller and supplies a much bigger but flexible support to the roller to work stable on big pressure.
Hydraulic biomass briquette machine is also called wood briquette machine or biomass brick machine. Hydraulic biomass briquette machine is the newest model briquette machine made by GEMCO. It is mainly used to produce wood or sawdust briquettes, and also can process other biomass materials like rice husk, straw, paperboard and sugarcane bagasseor.
After pulverized by hammer mill, the powder wood or sawdust with moisture content of 12% will be put into the material bin. Then they are conveyed to the briquetting cavity through a screw conveyor. After that, the materials are pressed by hydraulic pressure into briquettes and pushed out.
As our star biomass briquetting product, GC-HBP125 hydraulic briquette making machine from AGICO can significantly reduce the size of all kinds of biomass material that you have as much as 90%, turning them into biomass briquettes with smaller volume, higher heating value concentration and easy for transporting. This new generation hydraulic briquette machine bring hydraulic system and its features into biomass fuel industry. By integrating Siemens intelligent PLC module, this briquetting machine realizes a better environment where making biomass briquettes is smarter, safer and quieter. This hydraulic briquette machine makes briquettes from kinds of biomass material, including hard and soft wood, chipboard, paper, wood shavings, saw dust, crop straw, etc.
If you are from furniture industry, or saw mills and so forth, GEMCO hydraulic briquette machine is the very right machine for you as it can help you dealing with the tons of wasted material by pressing them into compact high value biofuel briquettes, whose combustion performance is much better than the regular firewood or coal. This is definitely a one-stone-two-birds business.
It is mainly composed of oil tank, motor, oil pump, a number of solenoid valve, pressure gauge, heating and cooling system, etc. Hydraulic briquetting system has the advantages of low noise, simple operation, saving space, and light weight. It is designed with perfect overload protection system. The oil pump is driven by motor. Then through the electromagnetic directional valve, the action of each hydraulic cylinder can be controlled precisely and achieve the best briquetting result. Our hydraulic system is equipped with a pressure gauge, making it possible to display the pressure values under the current working status, so that the operator can easily control the briquetting process.
This biomass briquette making machine is also equipped with cooling and heating system to control the temperature of oil tank. The system will automatically start cooling or heating when it is higher or lower than set temperature. There is an oil filter in the oil tank. Cooling oil return adopts two-circuit. Once blocking, the one-way valve oil return can be open, to eliminate the safety trouble.
The electrical part is automatically controlled by PLC system through sensors and application. The parameter is set by the touch screen. There is position sensors mounted on the prepressing cylinder and master cylinder, in order to better control the oil tank and make briquettes with different specifications.
