Double roll crusher has a simple structure and less pulverization, and the tooth shape, size and arrangement on the roller surface can be changed depending on the nature of the material. Medium and fine crushing of medium hard and soft ore. For example, in the sulfuric acid plant, the pyrite ore is crushed once by a roller crusher to make the diameter reach 20~30mm, and then enter the double roll crusher for secondary Broken, the ore diameter is less than 5mm, to meet the requirements of the boiling furnace.

The roller crusher can be used for fine ore crushing various high and medium hardness ores and rocks in the industrial sectors such as mineral processing, chemical, cement, refractory materials, abrasives, building materials, etc., especially in the construction materials industry to produce melon stone and mung bean sand. The product has more excellent effects than the general crushing machine.

Working principle of roller crusher
The crushed material falls between the two rolls through the feeding port, and is crushed and crushed, and the finished material naturally falls. When there is a hard or unbreakable object, the roller can be automatically retracted by the action of the hydraulic cylinder or the spring, so that the roller gap is increased, and the hard or unbreakable material falls, thereby protecting the machine from damage. The two rollers that rotate in opposite directions have a certain gap, and the gap can be changed to control the particle size of the product.
