Project Overview
This project delivers a full-process PLC automatic control system for a large modern coal washing plant in Mongolia, covering the whole production chain from raw coal receiving, crushing, separation to dewatering. The integrated digital control solution drastically cuts manual operation, stabilizes production continuity and upgrades overall beneficiation efficiency.System Solution & Core Functions
Core Control Hardware & Software
We adopt Siemens S7-1500 PLC as the core control unit, with TIA Portal and STEP 7 Professional software for full programming, graphic configuration and program debugging. Through PROFINET industrial bus, the system achieves seamless communication with all field sensors, actuators and variable frequency drives. It undertakes full-process data collection, logical operation, automatic instruction issuance and real-time fault diagnosis to ensure coordinated, precise operation of every working procedure.
Automatic Coal Washing Process Control
Upper Computer Central Monitoring Platform
WINCC Professional is deployed as the HMI supervision platform to build a visualized graphical operation interface. It displays real-time equipment operating status and full-process parameter trend curves, supports remote online parameter modification, audible & visual fault alarms, and long-term historical production data archiving. Only two operators on duty in the central control room are capable of completing full-plant production management.
On-site Delivery & Customer FeedbackOur professional technical team traveled to the customer’s site to complete full equipment installation, wiring, program commissioning and system joint debugging. The entire automation system passed one-time acceptance and achieved successful startup without repeated adjustments.
Project Values & Benefits
The stable running performance and our responsive, efficient on-site technical service have won extremely high recognition and favorable comments from the Mongolian client. This project fully demonstrates our outstanding, high-efficiency technical service capacity for overseas industrial projects, and serves as a powerful benchmark case to support our continuous market expansion across global mining and mineral processing industries.Project AdvantagesThis fully automatic control system reduces on-site manual labor and safety hazards in harsh mining environments, stabilizes clean coal output and product quality, and delivers prominent energy-saving and cost-cutting benefits for coal washing enterprises.
