Roll sand making machine

The main modification of the hydraulic roller sand making machine is to replace the old spring with a hydraulic device. After a period of use, the old spring roller sand making machine requires manual adjustment of the spring pressure to meet the requirements of the finished product. The fully hydraulic roller sand making machine is automatically adjusted and will automatically supplement the pressure, and the pressure is also more accurate. The structure and working principle of the hydraulic roller sand making machine are the same except for the pressure structure

[Applicable materials] Sand crushing work for materials such as river pebbles, calcite, quartz, glass, marble, pebbles, bentonite, iron ore, bluestone, mountain stones, limestone, weathered sand, diabase, granite, basalt, etc.

[Performance Characteristics]:

1. Compact structure and energy saving 2. Low crushing force and good crushing effect 3. Newly upgraded fully automatic hydraulic system 4. Thickened roller skin and long service life 5. Integrated hydraulic spring, balanced flash protection, no vulnerable parts

【 Working Principle 】

The hydraulic roller sand making machine performs crushing operation through the rollers. The material enters between the rollers through the feeding port and crushes river pebbles through extrusion. There is a gap between the two rollers, and the gap between the two rollers becomes larger, resulting in a larger particle size of the material. Under the action of the compression spring, the gap between the two rollers becomes smaller, resulting in a smaller particle size of the material. By changing and adjusting the gap, the particle size of the material can be controlled,
