The double-roller crusher for sand and gravel plants is a common crushing equipment, which is mainly composed of two rollers arranged in parallel. Its working principle is to use the rotation of the roller to clamp the material between two rollers for crushing and grinding. The double-roller crusher for sand and gravel plants is usually used to crush medium-hard materials, such as limestone, quartz stone, etc., and plays the role of coarse crushing and medium crushing in the sand and gravel production line. This equipment has the characteristics of simple structure, convenient operation and low energy consumption. It is widely used in the crushing process of mining, building materials, metallurgy and other industries.
1. The double-roller crusher is better than the hammer sand making machine and does not need to replace wearing parts.
2. The sand has full grain shape, reasonable gradation, low over-grinding rate and high output.
3. Double-roller crusher has huge advantages over hammer crusher and impact crusher. The average service life of the roller sleeve is more than 2 years.
4. Huashengming’s high-chromium manganese steel wear-resistant material containing rare metal roller skin has applied for a national patent. The discharge particle size can be accurately adjusted and has applied for a national patent. The roller of the double-roller crusher has applied for a national patent.
Crushing and sand making work of river pebbles, calcite, quartz, glass, marble, pebbles, bentonite, iron ore, bluestone, mountain stone, limestone, weathered sand, diabase, granite, basalt and other materials.
1. The finished product has good grain shape and less over-powder.
2. The particle size of the finished product is simple and controllable
3. Reasonable structure, no clogging, no stickiness
4. Dual motors, full of power
5. The roller skin is made of highly wear-resistant manganese steel, which is more durable.
6. Low investment cost, economical and easy to use

Double-roller crusher for sand and gravel plants uses two sets of independently driven rollers to crush materials by squeezing and grinding shear forces generated by relative rotation. The material falls between the two rollers through the feeding port. After being squeezed and crushed by the pair of rollers, the finished product falls naturally. When encountering extremely hard or unbreakable materials, the rollers can automatically retreat by the action of the hydraulic cylinder or spring, making the gap between the two rollers The gap between the two rollers increases, and the hard or unbreakable materials fall naturally to ensure that the machine is not damaged. The two oppositely rotating rollers can adjust the pressure of the hydraulic cylinder or spring to control the discharging granularity of the product.
