Models and Specifications of Large Hydraulic Double-Roll Sand Making Machines
The hydraulic double-roll sand making machine, also known as the hydraulic double-roll crusher, is a piece of equipment designed with a variety of cutting-edge technologies. This large-scale machine offers high output without requiring excessive investment. It is used in industries such as mineral processing, chemicals, refractory materials, stone, and construction materials to finely crush materials of various hardness levels. It can produce both crushed stone and sand. Below, we will provide a detailed introduction to its models, specifications, working principles, and pricing.
The output of large hydraulic double-roll sand makers can reach 390 tons per hour. Additionally, models with capacities of 100 tons and 200 tons are available. They typically come in three discharge sizes—5mm, 10mm, and 20mm—with corresponding variations in output. There are five models in total, with the P1810 and P2012 being the larger variants. The appropriate model can be selected based on the raw material, required output, and finished product specifications. The specific models and parameters of the large hydraulic double-roll sand-making machine are listed in the table below.
The large hydraulic double-roll sand-making machine features a mechatronic design that ensures continuous, stable, and reliable operation. In sand and gravel aggregate and grinding systems, it generally increases output by 30%–40% while reducing total energy consumption by 20%–30%. It boasts a rational structure and comprehensive functionality.
Working Principle: The mechanism consists of a pair of parallel, horizontally mounted cylindrical rollers. When these rollers rotate toward each other, material fed into the inlet falls onto the rollers. Under the combined action of surface friction and its own weight, the material is drawn between the two rotating rollers, where it undergoes compression, impact, shearing, and crushing forces from the rollers. When these forces exceed the cohesive forces between the material’s crystal lattice, the material fractures into small pieces, achieving the crushing objective. The crushed material is then pushed out by the rotating rollers and discharged downward.
Equipped with an automatic control system, it operates smoothly and efficiently, offering cost savings compared to other crushing systems with equivalent performance.
Hydraulic adjustment maintains a stable operating gap between the roller shells within the range of 1–40 mm.
It features overload protection; when non-crushable objects enter between the rollers, the rollers automatically retract and then return to the preset gap.
Heavy-duty, thickened roller liners are used, made from rigorously selected materials that are wear- and impact-resistant. Combined with an automatic lubrication system, this significantly extends the service life of components.
The crushed product is cuboid in shape, with low content of needle- and flake-shaped particles, no internal cracks, and a fine particle size.
