Embodiment Construction

[0030] A method for controlling the discharge opening of a multi-hydraulic-cylinder cone crusher, the implementation steps of which are as follows:

[0031] 1. Analyze the control object, combine the working principle of multi-hydraulic cylinder cone crushing and the measurement principle of the discharge port, and propose a control plan.

[0032] 2. The implementation of the plan, using the multi-turn absolute encoder to detect the number of rotating teeth of the drive pinion, recording the position information of the fixed cone, using PLC for data calculation and logic control, and converting the size of the discharge port by measuring the pitch value.

[0033] 3. Program implementation, completed in three steps

[0034] (1) Read the output value of the encoder and convert the Gray code into a double integer value.

[0035] (2) New liner calibration: When the cone crusher is replaced with a new liner, this position is calibrated as the absolute zero point of the new liner, ...

Abstract

The invention discloses a control method used for a discharge opening of a cone crusher with multiple hydraulic cylinders. The method includes the steps of initial value setting, new lining plate calibration, discharge opening calibration and lining plate replacement. The discharge opening of the cone crusher with the multiple hydraulic cylinders can be accurately measured through an absolute value encoder, and the problems existing in a proximity switch pulse counting method are solved.

Description

technical field [0001] The invention belongs to the technical field of automatic control of mining machinery and equipment, and is specially used for the calibration of the liner of the multi-hydraulic-cylinder cone crusher, and the measurement and adjustment of the discharge port. Background technique [0002] The multi-hydraulic cylinder cone crusher is mainly used in the medium and fine crushing system of ore. It has a good crushing effect on ore, especially for high hardness ore, and its crushing effect is more obvious. In the production process of the crusher, the size of the discharge port determines the particle size of the discharge. How to accurately measure and adjust the discharge opening affects the production efficiency of the crusher to a certain extent. [0003] The commonly used method is the proximity switch pulse counting method. Two proximity switches are installed at the same end of the gear. During the rotation process, there is a certain phase differen...
