In modern engineering construction, high-quality sand and gravel is an indispensable basic material. As a natural stone with high hardness and good wear resistance, pebbles can be made into machine-made sand with uniform particle size and excellent shape after crushing and shaping, which is widely used in construction, roads, water conservancy and other engineering fields. However, pebbles are often affected by moisture during processing, resulting in reduced production efficiency and even equipment damage. In order to solve this problem, the hydraulic roller sand making machine came into being, and became a fierce leader in the wet sand making production line.
Hydraulic roller sand making machine is a kind of equipment that uses two relatively rotating rollers to extrude and crush materials. Its core strength lies in its unique hydraulic protection system, which automatically adjusts the size of the discharge opening in the event of non-crushable objects, thus avoiding overload damage to the equipment. In addition, the hydraulic roller sand making machine also has a good self-cleaning function, which can maintain stable working efficiency even in pebble raw materials with large water content.
In the process of pebble sand making, the presence of moisture is a problem that cannot be ignored. When the traditional sand making machine is dealing with wet materials, it often reduces the crushing efficiency due to the materials adhered to the rollers, and even causes the rollers to slip, affecting the quality of the finished product. The hydraulic roller sand making machine can effectively control the production effect of wet material by adjusting the pressure between the two rollers, because the hydraulic system has enough pressure to realize the effective refinement of the material when processing the material with large moisture content, and can also effectively prevent the material from sticking, so as to ensure the continuous operation of the equipment and the high quality of the finished product.
The working principle of the hydraulic roller sand making machine is to use the high-pressure hydraulic system to drive the rollers to rotate relatively, and the material falls between the two rollers from the feed port, and falls naturally after being squeezed and crushed or removed by the scraper under the roller. When encountering hard or unbreakable materials, the hydraulic system will react quickly and increase the discharge port to allow the material to pass through smoothly, thus avoiding damage to the equipment. This intelligent protection mechanism greatly extends the service life of the equipment and reduces maintenance costs.
In practical application, the performance of the hydraulic roller sand making machine is remarkable. For example, in the pebble sand making production line of a water conservancy project, the traditional sand making machine cannot work normally due to the large water content of the raw materials. After switching to the hydraulic roller sand making machine, not only the production efficiency has been increased by 30%, but also the particle size uniformity of the finished sand has been significantly improved, which fully meets the engineering quality requirements.
