Hydraulic roller sand making machine Fully automatic hydraulic roller sand making machine is mainly used in the crushing and sand making operations of various ores, rocks and construction wastes, especially good at processing medium to hard materials, such as limestone, pebbles, river pebbles, granite, basalt, dolomite, sandstone, etc. It is widely used in mining, construction, highways, railways, water conservancy and hydropower, chemical industry, environmental protection and other industries, and is used to produce excellent machine-made sand to meet the aggregate needs of concrete mixing plants, mortar production lines, dry mortars, ready-mixed mortars and other fields.
Introduction to the advantages of automatic hydraulic roller sand making machine:
High degree of automation: integrated advanced PLC control system to achieve remote control and automated production, can automatically adjust crushing parameters, reduce manual intervention, and improve production efficiency.
Precise particle size control: The spacing between the two pairs of rollers can be accurately adjusted through the hydraulic system, which can effectively control the discharge particle size and ensure that the sand and gravel have a good particle shape and a reasonable gradation.
Overload protection: With hydraulic overload protection device, when there are unbreakable objects entering or the equipment is overloaded, the roller distance can be automatically adjusted to avoid equipment damage.
High efficiency and energy saving: Hydraulic drive, low energy consumption, high crushing efficiency, and relatively low operating costs.
Strong adaptability: It is suitable for all kinds of hardness materials, and can flexibly adjust the crushing strength and discharge particle size according to the characteristics of the material, and has a wide range of applications.
Convenient maintenance: The equipment structure is reasonably designed, and the parts are replaced and maintained simply, which greatly reduces the downtime and maintenance costs.
The working principle of the fully automatic hydraulic roller sand making machine is to use two crushing rollers installed in parallel and rotate in opposite directions to continuously extrude and shear the materials entering the machine. The material is subjected to intense pressure between the two rollers and is forced to break into sand grains that meet the requirements. The hydraulic system is responsible for adjusting the distance between the two crushing rollers to control the particle size of the crushed sand and gravel. At the same time, when encountering too hard or unbreakable objects, the hydraulic system can automatically increase the distance between the two rollers, let foreign objects pass through or release the overload state, and effectively protect the equipment from damage. The entire crushing process achieves efficient, precise and safe crushing and sand making.
