Automatic adjustment device for roll gap of roll crusher, and working method

Abstract

The invention discloses an automatic adjustment device for the roll gap of a roll crusher, and a control method. A vibrating screen carries out screening separation on the materials crushed by the crusher according to particle sizes; a belt weigher A1 and a belt weigher A2 weigh the undersize materials and the oversize materials of the vibrating screen separately; a movable manipulator grabs the undersize materials of the vibrating screen and places the undersize materials in a particle size detector; the particle size detector detects the material particle sizes of the undersize materials ofthe vibrating screen; a computer control system acquires the weighing data of the belt weighers and the particle size data of the particle size detector and obtains the roll gap adjustment parameter of the crusher through a corresponding control algorithm; and an electrohydraulic control system of a valve-controlled hydraulic cylinder controls the movement of the hydraulic cylinder according to the roll gap adjustment parameter of the computer control system, thereby realizing automatic adjustment for the roll gap. Through the abovementioned automatic adjustment device and control method, automatic adjustment for the roll gap of the crusher can be realized, so that the particle sizes of the crushed materials are ensured, the product quality is improved, and the production efficiency is increased.

Description

technical field [0001] The invention relates to an automatic adjustment device and a working method of a crusher, in particular to an automatic adjustment device and a working method for the roll gap of a roller crusher. Background technique [0002] The roller crusher is suitable for crushing medium-hard materials in industries such as cement, chemical industry, electric power, metallurgy, building materials, and refractory materials, such as limestone, slag, coke, coal, and other materials. Due to the close relationship between the gap between the roll gap of the crusher and the crushing particle size of the material, the counting method, sieving method, electromagnetic wave method and other methods are often used to detect the particle size, and then rely on manual adjustment of the roll gap according to the particle size detection results. Manual adjustment of the roll gap often requires Multiple adjustments can make the particle size of the crushed material meet the qua...
