Solution for Intelligent Crushing Control System

According to the actual situation of the crushing system process, combined with the idea of "creating first-class belt management" of the company, the crushing control system takes "simplicity, safety, practicality and reliability" as the principle, and takes eliminating the belt guarding post as the goal, and integrates belts into the centralized-control system. The main control system collects manual and automatic operation signals, overheating signals, current signals, belt off-tracking and under-speed signals, rope-pulling signal and others, realizes interlocking control of the whole process. The system can remotely control the feeding trolley at the control center to exempt workers from exposing in the dusty site. The crusher can realize constant power control.

The system real time monitors production process parameters, real time uploads equipment running status and parameters (such as motor running current, the oil pressure of lubrication system, oil temperature, belt slip, off tracking, existence of iron, etc.), and participate in the system operation interlock, protect the safe operation of the equipment, and avoid emergency shutdown. The safe startup conditions of important equipment, such as cone crushing equipment involves in system start-stop interlock. The emergency stop signal is used as the interlock condition of starting the system, and the system starts in inverse process and stop in forward process. If there is a fault shutdown, stop equipment according to the pre-scheduled shutdown mode, preventing further expansion of the fault.

The core concept of intelligent crushing system control

Monitoring and timely adjusting three - level throats;

Effectively increase the throughput of the crushing grating, which is conducive to reducing the running time of the crushing system, improving the through capacity of the fine crushing system, and effectively reducing the unit consumption of crushing;

Tap the potential of the crusher efficiency, monitor and reasonably control crushing cycle load, optimize the size composition of the final product of crushing, effectively improve crushing fineness, realize the constant power control of the fine crushing machine, which is conducive to improving the size composition. The improvement of the particle size of crushing is conducive to improving the working ability in the next process (the machine-hour capacity of the ball mill), so as to achieve the goal of "more crushing and less grinding".

Equipment interlock protection system, belt system protection, crusher protection and other related equipment protection system can efficiently, orderly, intensively start and stop system.

Solution for Intelligent Grinding And Separation Control System

The intelligent grinding and separation control system stabilizes the grinding process flow, and stabilizes the machine-hour processing capacity of the grinding equipment on the basis of ensuring that the grinding products meet the separation indicators. Automatic interlocking control and state monitoring of the entire process equipment and corresponding water volume and concentration control.

In the grinding system, manually judge the mill load to adjust the feeder operation status. Due to the untimely adjustment and unstable operation, the mill often has the phenomenon of "empty stomach" or "swelling stomach", which affects the quality of the entire grinding process.

Stage1 grinding is the entrance of the grinding process. The machine-hour processing capacity in stage1 grinding station represents the processing capacity of the grinding process. If the product quality is qualified and the subsequent process allows, increasing the process processing capacity will bring more benefits. Therefore, the stability of stage1 grinding control is the most critical factor in the control of the grinding process.

Through the intelligent ball-milling control system to stabilize the grinding process flow, fuzzily control the process water supply and ore feeding ratio adjustment, on the basis of ensuring that the grinding products meet the separation indicators, the machine-our processing capacity of the grinding process can be stabilized and the equipment operation status can be monitored.

Solution Unattended Belt Conveyor Consulting

Background

Belt conveyors are the "big artery" connecting different processes in the beneficiation production, which occupies a very important position in the production. Whether conveyors can operate normally and effectively directly affects the stable and smooth running of the whole plant.

The unattended belt conveyor system removes the custodial posts and realizes the unattended belt conveyor system through effective technical and management means; and establishes a new production organization mode, implements a professional spot inspection and cleaning system, and the belt conveyor system can stably run in long term.

Video surveillance for remote monitoring:

Set up cameras at important locations to realize remote monitoring of key locations.

Automation technology ensures belt conveyors can stably run

Install the detection and protection devices such as belt deviation, slippage and material blocking which are connected to the control system to realize real-time monitoring and controlling the running status of the belt conveyors.

Strengthen belt conveyor management

To realize unattended belt conveyor running, in addition to necessary technical means, it is necessary to strengthen the management to realize the long-term stable running.

The unattended belt system can bring huge economic and management benefits:

Reduce the number of posts and save labor costs;

Reduce the problems of material loss and belt deviation, and reduce the labor intensity of cleaning and on-site processing problems;

The belt operation efficiency is improved, the downtime is reduced, and the production efficiency is improved;

By the control of dust, material loss, and deviation, the custodial posts are cancelled, the occupational diseases probability is reduced, and the accidents caused by belt are eliminated.
