Customized design: According to the material hardness provided by the user, measure the pressure of the material, and then design the parameters of the roller press to ensure that the machine can effectively crush materials of specific hardness.

Hard connection and universal joint technology: The movable roller and fixed roller and the power system adopt hard connection, that is, coupling connection, and the movable part adopts universal joint technology. This design avoids the problem of belt slippage when handling large materials in older belt-driven models.

Taper welding technology: The roller surface adopts the taper welding technology of a large hydraulic roller press. Repair welding can produce more than 80,000 tons of materials at a time, and the cost is low, about 1,000 yuan. The annual maintenance cost of the whole machine does not exceed 2,000 yuan.

Unpowered powder selection structure: The feeder adopts an unpowered powder selecting structure. Before the material enters the roller press, it first passes through the unpowered powder selection device to screen out materials smaller than 3-8mm and does not enter the roller press. The coarse material is evenly fed into the roller press through the vibrating feeder, which can improve the crushing efficiency.

Energy saving and power consumption: The power consumption of this machine is only half of that of the hammer crusher, which has good energy saving effect.

Automatic protection and adjustment function: When encountering extremely hard or unbreakable objects, the rollers can automatically retreat with the help of springs, increasing the roller gap to allow the extremely hard or unbreakable objects to fall, thus protecting the machine from damage. At the same time, by adjusting the roller gap, the discharge particle size can be controlled, thereby changing the output per unit time.

The hydraulic roller press is an efficient crushing machine that uses the friction of the roller surface to bite the material into the crushing zone and crush the material through extrusion or splitting. The working principle of this machine is based on the hardness and brittleness of the material, by applying sufficient pressure to break the material.
In a hydraulic roller press, the roller surface is an important working part. The roller surface is in contact with the material, and the material is fixed and bitten into the crushing zone through friction. In order to improve the crushing efficiency, especially when used for coarse crushing or when the crushing ratio needs to be increased, teeth or grooves are often made on the roller surface. These teeth or grooves can increase the splitting effect, making the material more easily broken.
The advantage of a hydraulic root press is its high efficiency and energy saving. Since it crushes materials through the friction of the roller surface, no additional power is needed to drive the cutter or hammer, thus saving energy consumption. At the same time, because the structure of the hydraulic roller press is relatively simple, its maintenance and repair work are also relatively easy, reducing operating costs.
In addition, hydraulic roller presses have a wide range of applicability. It can be used to crush materials of various hardness and brittleness, such as ore, coal, limestone, etc. By adjusting the pressure and roller surface design, the hydraulic roller press can achieve different crushing effects and meet different production needs.
In general, the hydraulic roller press is an efficient, energy-saving and adaptable crushing machine. By utilizing the friction and splitting effect of the roller surface, it can crush materials and provide an effective crushing solution for various industrial productions.
