Raw Material Preparation & Raw Milling
Raw material preparation establishes the continuous flow of limestone, clay, and corrective materials before raw meal enters the next process stage. VITECH engineers, integrates, and programs control systems from receiving stations, crushers, and preblending storage through weigh feeders, raw mills, and raw meal silos. The solution focuses on equipment sequencing, mechanical protection, level and flow measurement, and coordinated conveying across the material front end.
1. Crushing & Material Receiving
Limestone, Clay & Additive Receiving
Integrating receiving hoppers, apron feeders, grizzlies, and level instruments to regulate limestone, clay, and corrective-material flow from trucks or quarry routes into crushing systems.
Crusher Sequencing & Protection
Programming crusher start permissives, feeding sequences, and shutdown logic while monitoring motor current, vibration, bearing temperature, tramp metal, and blockage conditions.
2. Stacker, Reclaimer & Preblending Storage
Stacker Automation
Controlling stacker travel, slew, and luffing according to the selected stockpiling pattern while coordinating conveyors, trippers, and position measurement.
Reclaimer Sequencing & Stockpile Management
Controlling bridge or scraper reclaimers to the required material rate while monitoring torque, position, and travel limits and linking inventory data to outgoing feed routes.
3. Belt Conveyor Control
Conveyor Sequencing & Route Selection
Implementing reverse-flow startup, material-clearing shutdown, and route selection through diverter gates according to source, destination, and equipment readiness.
Belt Protection & Material-Flow Monitoring
Integrating pull-cord, belt-sway, zero-speed, slip, chute-blockage, and rip detectors with sectional trip handling to limit material accumulation at transfer points.
4. Weigh Feeding & Proportioning
Weigh Feeder Control
Integrating load cells, weighing controllers, and VFDs to regulate each material stream while managing zero calibration, totalizers, and feed-deviation alarms.
Raw Mix Proportioning & Inventory Monitoring
Coordinating limestone, clay, and corrective-material setpoints according to raw-mix recipes while consolidating flow, silo level, and consumption data for material-balance supervision.
5. Raw Mill Automation
Raw Mill Start & Stop Sequences
Coordinating lubrication, hydraulics, main motor, separator, fans, and feeding through permissives, with normal shutdown and trip responses defined by the engineered cause-and-effect matrix.
Grinding Circuit & Mill-Load Monitoring
Acquiring differential pressure, vibration, temperature, motor power, separator speed, and gas flow while coordinating fans, dampers, and feed against process setpoints.
6. Raw Meal Silos & Homogenization
Silo Level, Filling & Discharge Control
Integrating radar level measurement, high-level switches, distribution valves, and discharge equipment while selecting fill and discharge silos according to available capacity and route permissives.
Aeration & Raw Meal Homogenization
Programming aeration cycles, silo-bottom zoning, and extraction sequences for raw meal blending while monitoring air pressure, valves, and blower status at each step.
