Granite sand making machine Granite roller sand making machine is a kind of mechanical equipment specially for crushing and sand making granite and other materials with extremely high hardness. Its working principle is mainly to use two relatively rotating high-hardness wear-resistant rollers to extrude, grind and shear the material, and crush the large granite into excellent sand and gravel products that meet the market demand.
Working principle: The granite material enters the inside of the roller sand making machine from the feed port, and two symmetrically arranged crushing rollers made of high-strength wear-resistant materials (such as high-manganese steel, wear-resistant alloys) rotate synchronously or asynchronously. When the material falls between the two rollers, it is crushed by the action of huge squeezing and shear forces. By adjusting the gap between the two rollers, the particle size of the sand and gravel product can be controlled.
Equipment features: Efficient crushing: Because of its unique crushing principle, the roller sand making machine has a good crushing effect on granite and other hard materials, and the output of sand and gravel has regular grain shape and gradation.
Adjustable particle size: The crushing particle size can be easily adjusted according to customer needs to adapt to different engineering and industrial standards.
Wear-resistant and durable: special wear-resistant materials are used for key parts such as the roller surface, which greatly prolongs the service life of the equipment and reduces maintenance costs.
Energy-saving and low-consumption: Optimized design and drive system with higher crushing efficiency and lower energy consumption than comparable equipment.
Overload protection: Equipped with a perfect overload protection device to avoid damage to the equipment due to excessive hardness or excessive material.
Applications: Granite roller sand making machine is widely used in construction, highways, railways, bridges, water conservancy, airport runways and other infrastructure construction to produce high-quality machine-made sand to meet the sand needs of concrete aggregates, mortars, roadbed filling materials, etc.
Models and specifications: There are a variety of models and specifications of granite roller sand making machine to choose from, and the appropriate model should be selected according to the actual production needs, considering the hardness, particle size, production capacity and other factors of granite.
Operation and maintenance: Correct operation and regular maintenance are the key to ensure the efficient and stable operation of the granite roller sand making machine. This includes adjusting roll clearances in a timely manner, keeping them well lubricated, replacing wear parts regularly, and implementing preventive maintenance measures.
