Abstract

The invention discloses an automatic roller gap adjusting system for a four-roller crusher, and belongs to the technical field of four-roller crushers. The automatic roller gap adjusting system comprises a rough crushing control system and a fine crushing control system. Each of the rough crushing control system and the fine crushing control system comprises a fixed roller, a movable roller, a proportional valve, a hydraulic cylinder, a displacement sensor and a pressure sensor, each proportional valve is arranged on a bearing seat of each corresponding movable roller, the hydraulic cylinders are mounted on a rack, and piston rods of the hydraulic cylinders are connected with the proportional valves. The displacement sensors are used for detecting the distances between the fixed rollers and the movable rollers. The automatic roller gap adjusting system further comprises a PLC, the displacement sensors and the pressure sensors feed detection signals back to the PLC, and the PLC controls adjustment of the proportional valves. According to the automatic roller gap adjusting system of the four-roller crusher, the PLC is adopted for achieving accurate control over the proportional valves, and roller gaps are dynamically tracked and adjusted.

Description

technical field [0001] The invention relates to the technical field of four-roll crushers, in particular to an automatic adjustment system for roller gaps of four-roll crushers. Background technique [0002] The four-roller crusher is a secondary and fine crusher with reasonable structure, compact and reliable operation. Its working principle is: relying on the friction force on the surface of the rollers, the materials are brought into the working chamber of the two rollers, and the materials are rolled and broken by extrusion and shearing force. The control of the particle size of the product is realized by driving the bearing seat connected with the roller shaft to move back and forth through the hydraulic protection adjustment system, and then adjusting the gap between the two rollers. [0003] The existing method of adjusting the roll gap of the four-roll crusher usually adopts manual adjustment of the oil cylinder stroke to achieve the roll gap required by the process...
