At present, society is developing faster and faster, and the sand making industry is also developing by leaps and bounds. Sand and gravel aggregates have a wide range of sources and are much cheaper than natural sand. They have gradually replaced natural sand and become the main force in the sand and gravel aggregate market. The roller stone crusher is another breakthrough in the field of sand and gravel aggregate production equipment manufacturing. This equipment uses two motors to drive two pairs of rollers to squeeze and grind materials. Fine crushing operations where the roller crushing degree is less than 80mm and the finished product particle size is required to be 50 mesh-20mm.

Why choose Huashengming

1. The roller stone 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. Roller stone 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 roller stone crusher has applied for a national patent.

Applicable materials
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.

working principle

The double-roller crusher performs crushing operations through rollers. The material enters between the rollers from the feed port, and crushes the river pebbles through extrusion. There is a certain gap between the two rollers. The gap between the two rollers becomes larger, and the material discharge granularity becomes larger. Under the action of the compression spring, the two rollers The roller gap becomes smaller, and the discharge particle size becomes smaller. By changing the adjustment gap, the discharging granularity of the material can be controlled.
