Double roller crusher,also known as the double roll sand making machine or double roll crusher, is suitable for crushing medium hardness materials in industrial sectors such as cement, chemical, power, metallurgy, building materials, refractory materials, etc. The double roll crusher is used for medium and fine crushing of materials such as limestone, slag, coke, coal, etc. The roller sand making machine is reliable in operation, easy to maintain, and has low operating costs, with adjustable discharge particle size. The roller crusher is a mechanical device that uses the frictional force of the roller surface to bite the material into the crushing zone, causing it to withstand compression or splitting and be crushed. When used for coarse crushing or to increase the crushing ratio, teeth or grooves are often made on the roller surface to increase the splitting effect.
Product Feature
1.Can be designed and manufactured according to the hardness of the material
It can be designed and manufactured based on the hardness of the material, that is, according to the material provided by the user, the bearing pressure of the material is first measured, and then the various parameters of the roller crusher are designed.
2.Less dust and low noise
The roller sand making machine has less dust and low noise during the production process, making it an environmentally friendly crushing equipment.
3.Protection mechanism to avoid damaging the machine
When encountering hard or unbreakable objects, the roller can automatically retract by the action of the spring, increasing the gap between the rollers and causing the hard or unbreakable objects to fall, thereby protecting the machine from damage.
4.Adjustable Discharge and Output
The double roll crusher can control the discharge particle size by adjusting the gap between the rollers, thereby changing the hourly output.
5.Cheap and Easy to Use, High Cost-Effectiveness
The roller crusher can crush materials with a compressive strength of less than 160MPa, and the output is cubic and fine. It is an inexpensive and easy-to-use crushing and sand making machine.
Product Working Principle
Roller crusher is a mechanical device that uses the frictional force of the roller surface to bite the material into the crushing zone, causing it to withstand compression or splitting and be crushed. When used for coarse crushing or when increasing the crushing ratio, teeth or grooves are often made on the roller surface to increase the splitting effect.
