Embodiment

[0035] The roll gap adjustment method of a roll crusher roll gap in this embodiment is applied to such as figure 1 In the crusher shown, the material is thrown into the gap between the fixed roller 1 and the moving roller 2 and passes through, and the material is squeezed and crushed by the fixed roller 1 and the moving roller 2 when passing through; The first regulating valve 6a has two oil pipes connected with the hydraulic station respectively, and the first regulating valve 6a also has two oil pipes connected with the rod chamber and the rodless chamber of the first oil cylinder respectively, and the piston of the first oil cylinder The rod is connected with the first bearing seat of the moving roller 2. When the first oil cylinder acts, it drives the moving first bearing seat to move, causing the material between the moving roller 2 at the end of the first bearing seat and the fixed roller 1 to be squeezed, causing The load F1 of the first oil cylinder changes; the first ...

Abstract

The invention relates to a method for adjusting the roll gap of a roll crusher, belonging to the technical field of automatic control. A method for adjusting the roll gap of a roll crusher, the following steps are performed: 1) The control system of the crusher collects the actual data of the production equipment; 2) The first position sensor and the second position sensor of the crusher transmit position signal, detect the actual position value of the crusher roll gap in real time, and ensure that the actual position value of the roll gap is consistent with the preset position value; 3) record the effective production time T of the crusher / ;4) Calculate the theoretical wear value; 5) Adaptively adjust the wear coefficient K; 6) Store the adjusted wear coefficient K and update it to the current wear coefficient K; 7) Use the adjusted wear coefficient K to calculate the roll gap L, and Return the calculated roll gap L to step 2) to realize the adaptive adjustment of the roll gap L. The method automatically and timely accurately controls the position of the roll gap, and realizes a high degree of automation in production.

Description

technical field [0001] The invention relates to a method for adjusting the roll gap of a roll crusher, belonging to the technical field of automatic control. Background technique [0002] During the use of double-roll and four-roll crushers, the operators are operated one by one at regular intervals, which is time-consuming and labor-intensive. It is difficult to timely and accurately control the roll gap, which seriously affects the production rhythm and wastes human resources. Through this method, the operator only needs to set the parameters, artificial intelligence calculates the target roll gap position, and the PLC system automatically starts the hydraulic system and timely and accurately controls the roll gap position according to the requirements of the target setting and the process start request. This technology realizes a high degree of automation in production, and the hydraulic system realizes automatic roll gap compensation according to the rolling time, averag...
