double roll crusher sand making machine with two roller

The feed size of the double roll crusher sand making machine is generally not more than 30mm, and the processing capacity can reach 28 to 40 cubic meters per hour, which is suitable for medium-sized continuous operation requirements, and suitable for the preparation of high-quality sand and gravel aggregates for a variety of rock-based raw materials.

The structural characteristics of the double roll crusher sand making machine:

1. wear-resistant roller ring: the surface of the roller ring is made of high hardness alloy material, which has strong anti-wear ability, prolongs the service life, and adapts to the high-intensity sand making environment.
2. compact structure: the overall design is compact, small footprint, easy to install and site layout.
3. spring protection device: with automatic overload protection function, can effectively prevent the damage caused by non-crushable materials into the equipment.
4. Flexible adjustment: the granularity of the discharged material can be precisely controlled by adjusting the gap between the two rolls to meet the fineness requirements of different projects.
5. stable transmission system: the use of dual motor drive with deceleration mechanism, stable transmission, low noise, reliable operation.

Double roll crusher sand making machine performance advantages:

1. Excellent effect of fine crushing: the material is subjected to high-intensity extrusion and shear effect between the rollers, and the sand grains made are uniform in shape and reasonable in grading.
2. lower energy consumption: compared with the impact type, hammer type sand making machine, double roll crusher sand making machine in the same output lower energy consumption.
3. low operating costs: equipment with fewer wear parts, simple maintenance, almost no dust leakage during operation, good environmental protection.
4. strong adaptability: both dry and wet operating environment can be stable operation, low moisture requirements for materials.
5. fast return on investment: equipment costs moderate, fast production, quick results, is a cost-effective choice for small and medium-sized sand and gravel plant.

The working principle of double roll crusher sand making machine:

Mainly through a pair of relatively rotating rollers, the material fed between the two rollers is extruded and crushed. The dual motors transfer the power to the reducer through the triangle belt, and then the coupling drives the two rollers to rotate in the opposite direction. The material will fall into between the two rollers evenly from the inlet, and will be cracked or crushed into small particles after being strongly extruded, and then discharged from the outlet.

Among them, one side of the roller is fixed, and the other side is supported by a spring mechanism with a certain floating range. By adjusting the spring pressure and the distance between the two rollers, the discharged particle size can be flexibly controlled to improve the quality and efficiency of the finished sand.

Application fields of double roll crusher sand making machine:

1. Mechanism sand production: reprocessing of natural river pebbles, lapis lazuli, basalt, etc. to meet the standard of construction sand.
2. mine fine crushing section: fine crushing processing in metal and non-metal ore crushing link, improve the efficiency of mineral processing.
3. Cement and refractory industry: It is used for pre-crushing of cement raw materials or clinker, refractory bricks raw materials to improve the activity of materials.
4. Infrastructure projects: provide high quality fine aggregate for highway, high-speed railway, municipal engineering, water conservancy project, etc.
5. quartz sand, glass raw material processing: good adaptability for fine grain preparation of silica, quartzite and other hard materials.
