Problems solved by technology
When the material is squeezed, the material will have a reaction force on the pressure roller, causing the movable roller to retreat, so that the roll gap will become larger. At the same time, when the material enters the pressure roller, the driving side and the non-driving side will produce a gap deviation. These two phenomena will affect the stable operation of the roller press, reduce production efficiency, and shorten the life of the roller press, which is not conducive to the production and utilization of building materials and mining industries. Therefore, the above problems need to be solved

The invention discloses a hydraulic system for a rolling machine (high-pressure roller mill), and belongs to the field of rolling machines and high-pressure roller mills in building material and mine industries. The hydraulic system of the rolling machine (high-pressure roller mill) comprises an energy accumulator, a main hydraulic cylinder and a pressure sensor, wherein the energy accumulator is communicated with a hydraulic station oil supply pipeline through a third electromagnetic exchange valve and is communicated with a hydraulic station oil tank through a second electromagnetic exchange valve; and the main hydraulic cylinder and the pressure sensor are connected between a check valve and the second electromagnetic exchange valve as well as between the energy accumulator and the third electromagnetic exchange valve simultaneously. By the hydraulic system for the rolling machine (high-pressure roller mill), the roller gap between a fixed roller and a movable roller can be relatively stabilized, so that the rolling machine is operated stably, safely and reliably; therefore, the service life of the rolling machine (high-pressure roller mill) is prolonged, and the hydraulic system is extremely easy and convenient to operate.
Description
technical field [0001] The invention relates to a hydraulic system suitable for roller presses and high-pressure roller mills used in building materials and mining industries. Background technique [0002] Roller presses and high-pressure roller mills used in the building materials and mining industries rely on the pressure between the two rollers to crush the material when the material passes between the fixed roller and the movable roller of the roller press (high roller mill). When the material is squeezed, the material will have a reaction force on the pressure roller, causing the movable roller to retreat, so that the roll gap will become larger. At the same time, when the material enters the pressure roller, the driving side and the non-driving side will produce a gap deviation. These two phenomena will affect the stable operation of the roller press, reduce production efficiency, shorten the life of the roller press, and be unfavorable for the production and utilizati...
