Cold roll briquette machine is a roll type briquetter used for room temperture briquetting work. It can work under a very high pressure and make briquette under a low moisture with shapes like oval, pillow, square, etc. Widely used in industries like metugally, mining, chemical, etc.

Served Industries: Fuel, Mining, Metallugry, Chemical, Building, Foods, etc.
Common material: Coal, steel mill by-product, ores, charcoal, metal, salt, etc.

MAXTON supplies spare parts for roller briquette machines, including rollers, screws, and more, ensuring comprehensive support for your maintenance needs.

Working Principles

The material passes through the buffer bin, and then goes past the feeder, quantitatively and evenly enters the feed port of the roll briquette machine. After that, it reaches the pre-compression feeding device of the machine.

To maintain a stable material level in the pre-compression feeding device, the screw in the pre-compression feeding device will force the material into the middle of the rolls. The screw will pre-compress the material and remove the gas as much as possible from particles, and moves the material to be transported to the middle of two rolls.

At the arc-shaped notch of the rollers, the pockets of the same shape are evenly distributed on the surface of the two rolls. Through the meshing transmission of the synchronous gear reducer, the two rollers run at the same speed and opposite to each other, thus the material will be transported to the arc-shaped notch. The material is bitten into the groove and forced to compress. As the rolls continue to rotate, when they exceed the center line, the finished briquette will fall out of the pocket under the action of its own elasticity and gravity, thereby completing the process of briquette making.

Features

  1. Roll raw material comes from high-quality suppliers, supplemented by Maxton’s excellent processing capabilities and quality control, the life of the roll is very high.
  2. Different roll assembly forms to meet the needs of different customers. Common assembling: tire roll, segment, etc.
  3. Driven by hard-tooth surface output double-shaft reducer, the pressure on the rollers is evenly distributed, the life of the roll is greatly extended.
  4. Reducer comes from top suppliers or Maxton shall produce and manufactures itself to ensure the continuous operation of the equipment under harsh working conditions and provide a strong guarantee for the customer’s operation.
  5. Different feeding forms and feeding structures meet the different requirements of customers. The materials used for the feeding screw are exquisite, and the working life of the screw is improved by using wear-resistant materials and wear-resistant technology.
  6. Sealing structure is improved, no material leakage at low levels after long-term operation, helping customers improve the briquette quality and save running costs.

  • Metal (aluminum chip, copper chip, electrolytic manganese, etc.)

Systems

Briquette with binder

The role of the binder is to reduce the friction between the material particles and between the particles and the pocket. The binder is generally a liquid or a soft and easily deformable substance, which has two functions:

1. A layer of binder which is evenly wrapped on the surface of the material particles can greatly reduce the roughness of the particle surface, facilitates the sliding between materials;

2. When the material particles move relative to the pocket, the binder lubricates the ball socket, which greatly reduces the friction between the material and the ball socket, which is beneficial to briquetting and increases the service life of the roll.

Special binder can also help to improve the performance of the finished briquette like water proof, high high-temperature strength, etc.typical briquetting making process with binder from Maxton

Examples:

  • Chrome ore with molasses/hydrated lime
  • Coal with bitumen
  • Coke fines with starch
  • Copper-nickel concentrate with lignosulfonate
  • DRI fines with molasses/ hydrated lime or sodium silicate / hydrated lime
  • Steel plant residues with molasses / hydrated lime

Briquette without binder

So many advantages of following a binder free briquetting way, raw materials are saved, a simple process, purer briquette, no harmful substances from binders, etc.

Binder-free briquette making, normally when the size of the raw material is suitable, the material is added to the briquetter at a constant speed and then make the briquette. In some cases, it is necessary to use the plasticity of the raw material under certain special conditions before briquetting.
