Briquetting machine is a pelletizing machine that can feed various kinds of dry and wet powder through the initial pressure unit into the roll press area and transform it into high bulk density ball.
Mainly applied in the coal, mining, metallurgy, fire-resistant materials, construction materials and other light metal industries.
General Features
With roller diameters of 520 to 1200 mm can be provided.
Specific pressure of 11 t/cm is forced to design on pre-pressing.
The material has a good extrusion effect with high pelletizing ratio and high-density briquettes.
Super wear-resistant roller surface is made with special bearing steel; this kind of roller surface has a good wear effect and a long working life.
Incorporating dual-output shaft reducer structure to improve the accuracy of the double rollers.
Completely-sealed gearbox is used with low noise and without oil leakage.
Uses ball groove alignment unit of high-pressure briquetting machine.
Incorporating hard-tooth-surface gears to greatly improve performance and life.
Adjustable-speed motor is used for preforming press; all wear parts are overlaid with wear-resistant alloy to improve service life.
A stand-alone hydraulic station can adjust pressure and have the special function of overpressure protection.
Item 001 – Super High-Pressure Briquetting Machine
Special equipment designed and produced for fine-grained (300 mesh or more) and light-weight powder based on the high-pressure briquetting machine.
Has many advantages like high pressure, good sealing effect, high efficiency and so on.
With a line pressure of 11 t/cm, it is an ultra high pressure machine suitable for forming briquettes of calcium carbide, ultrafine powder, etc.
The pre-pressing transmission works with the structure of a direct connection with the hard-tooth reducer motor; compared with the traditional open-belt drive, it is more stable, reliable, compact and sealed, which can avoid dust from entering the transmission system.
The motor incorporates a hard-tooth surface reducer with a direct connection structure; compared with the traditional briquetting machine motor that works by the pulley or coupling and the worm gear reducer connection structure, its power transmission efficiency and accuracy are greatly improved, and the feedback on the pre-pressing motor on the electronic control system is more direct and accurate.
The sealing device around the roller shells uses a scraper and arc baffle on the guide nozzle of the pre-presser made of special wear-resistant composite material, which forms multiple contact seals together with the roller shell to replace the old-style steel structure labyrinth seal; this greatly increases the tightness of the triangular compression zone to avoid large amounts of leakage raw and spray material, and can effectively protect the roller shell from damage because of the elasticity of the material itself, thereby greatly increasing the briquette formation rate and reducing useless energy consumption.
The hopper and spiral of the pre-presser can adjust the fine powder material with high gas content and strong fluidity; the silo and the feed inlet are enlarged to ensure sufficient material in the silo, and the material pressure of the pressing zone is greatly improved, which performs a better briquette forming effect.
The whole silo incorporates a closed structure, except for the air outlet, to ensure that the materials cannot overflow.
The lead, angle, length, and precision of the spiral have been improved so that the push material is more sufficient to facilitate the formation of the final briquettes.
Order Description
The equipment is supplied as right hand-installed generally; please specify in the contract if it needs to be installed as a left hand unit.
The capacity and energy consumption of the briquette machine are related to the material characteristics, final briquette size, etc.

Item 002 – High Pressure Briquetting Machine
Pelletizing machine that can feed various kinds of dry and wet powder through the preliminary pressure device into the roll press area and make into high bulk density ball.
Mainly applied in the coal, mining, metallurgy, fire-resistant materials, construction materials and other light metal industries.
Mainly used for ball forming of colored and ferrous metal ore powder, and feeding into the furnace for smelting to increase the added value.
Any metallurgical industry waste or auxiliary materials that need to be on the furnace all need high pressure briquetting machine; for example: quicklime, dust ash, sewage, oxide scale, steel slag, iron fine powder, aluminum ash powder, silico-manganese ore powder, and so on.
The main structure is that the original feed is basically converted into a three-way feed; the main roller and the secondary roller are pressed to compact the hemisphere, and the two hemispheres compacted with the rotation of the main roller are fed in the middle, and a second press is performed, thereby multiplying the pressure.
Has obvious effects on loose materials such as coke powder, oxide scale, dust ash, sludge, etc.
Product Principle – High Pressure Briquetting Machine
The main body is powered by an electromagnetic speed regulating motor, which is transmitted to the drive shaft through a pin and pin coupling through a pulley and a cylindrical gear reducer.
The drive shaft and the passive shaft ensure synchronized operation through open gears; the passive bearing housing is equipped with hydraulics at the rear.
The screw feeding device is driven by the electromagnetic speed regulating motor, and is rotated by the pulley and the worm reducer to force the pressed material into the main feeding port.
Due to the constant moment characteristic of the electromagnetic speed regulating motor, when the amount of material of the screw feeder is equal to the amount of material required by the main machine, a constant supply pressure can be maintained to stabilize the pellet mass.
If the feeding amount is too large, the feeding device is overloaded; if the feeding amount is too small, the pellet mass is unstable.
