Roller press hydraulic system and automatic pressure stabilizing device thereof

Abstract

The invention discloses a roller press hydraulic system and an automatic pressure stabilizing device thereof, and belongs to the roller press hydraulic system and a matched device. The automatic pressure stabilizing device comprises a hydraulic oil station (1), a left pressure stabilizing device (2) and a right pressure stabilizing device (3), wherein energy storage devices (4) and combined valve bodies are arranged in both the left pressure stabilizing device (2) and the right pressure stabilizing device (3); the energy storage devices (4) in the left pressure stabilizing device (2) and the right pressure stabilizing device (3) are communicated with oil cylinder working chambers (5) on the two sides of the roller press hydraulic system through pipelines respectively; and the combined valve bodies in the left pressure stabilizing device (2) and the right pressure stabilizing device (3) are arranged closely to oil cylinders on the two sides of a roller press respectively. The automatic pressure stabilizing device of the roller press hydraulic system provided by the invention has a simple overall structure, the problem of pressure fluctuation of the conventional hydraulic system of the roller press is solved well, an extrusion effect of a material is enhanced, and the yield of a roller press system is improved.

Description

technical field [0001] The present invention relates to a hydraulic system of a roller press and its matching devices. More specifically, the present invention mainly relates to a hydraulic system of a roller press and an automatic pressure stabilizing device thereof. Background technique [0002] Roller press, also known as extrusion mill and roller press mill, is a new type of cement energy-saving grinding equipment developed in the mid-1980s in the world. It can replace the ball mill pre-grinding system with high energy consumption and low efficiency, and can reduce steel consumption and noise. Function, suitable for the construction of new plants, and can also be used for technical transformation of old plants, so that the output of the ball mill system can be increased by 30-50%. After extrusion, the 0.08mm fine material accounts for 20-35%, and the smaller than 2mm accounts for 65-65%. 85%, the internal structure of small particles is filled with many tiny cracks due t...

AI Technical Summary

Problems solved by technology

The hydraulic system is an extremely important key component of the roller press. In the past, due to its many faults and poor reliability, the popularization and application of the roller press has been restricted for a long time. Stable, large fluctuations, poor pressure holding effect, resulting in large changes in the force of the roller press on the material, poor extrusion effect, affecting the output of the system, and can not give full play to the effect of increasing production and energy saving of the roller press
