Product Description
Roller crushers, also known as double-roll sand making machines or double-roll crushers, are suitable for crushing medium-hard materials in industries such as cement, chemicals, electricity, metallurgy, building materials, and refractory materials. They provide secondary and fine crushing of materials such as limestone, slag, coke, and coal. Roller crushers are reliable, easy to maintain, and cost-effective to operate. They also feature adjustable discharge size. Roller crushers utilize the friction of the rollers to force material into the crushing zone, where it undergoes compression or splitting. For coarse crushing or to increase the crushing ratio, teeth or grooves are often incorporated into the rollers to enhance the splitting effect.
How to choose suitable Double Roller Crusher machine?
1.Designed and manufactured according to the material's hardness.
Designed and manufactured according to the material's hardness, the double-roll crusher's parameters are designed based on the material provided by the user.
2.Low dust and low noise.
The double-roll crusher produces low dust and noise during production, making it an environmentally friendly crushing device.
3.Protection mechanism prevents damage to the machine.
When encountering hard or uncrushable materials, the rollers automatically retract due to spring action, increasing the gap between the rollers and allowing the hard or uncrushable materials to fall through, thus protecting the machine from damage.
4.Double-roll crusher sand making machine structure diagram
Adjustable output and capacity.Double-roll crushers can control the output particle size by adjusting the roller gap, thereby varying the hourly output.
5.Affordable, user-friendly, and cost-effective.
The double-roll crusher can crush materials with a compressive strength of up to 160 MPa. The output is cubic and fine, making it an affordable and user-friendly crusher.
How is works
Roller crushers use the friction of the roller surface to bite the material into the crushing zone, causing it to be squeezed or split and crushed. When used for coarse crushing or when a higher crushing ratio is required, teeth grooves are often made on the roller surface to enhance the splitting effect.
