3. Detailed Overseas Customer Application Case Of MTW Trapezium Grinding Mill Plant

A large limestone deep processing enterprise located in Peru (South America) specializes in producing desulfurization powder for local thermal power plants and construction stone powder. Before cooperating with Mascot, the factory deployed two sets of old 6R Raymond mill production lines, facing multiple severe production troubles: single line stable output only 8t/h, power consumption up to 35kW·h per ton limestone, frequent coarse powder overflow leading to failed power plant procurement inspection, serious workshop dust triggering environmental fines every quarter, and wear parts replacement every 4 months with high spare parts expenditure.

In early 2025, the customer contacted Mascot overseas sales and technical team, sent raw limestone samples for free test grinding, and invited our engineers to survey factory layout. Combined with customer target 25t/h hourly output demand, we customized one complete set of MTW175 Trapezium Grinding Mill Plant full production line, including feeding, lifting, drying, trapezoidal grinding, classification, dust collection, powder conveying and IoT intelligent PLC control system. After equipment finished production and container shipment, two professional Mascot engineers flew to Peru within 5 working days, completed equipment assembly, pipeline layout, electrical debugging and local worker operation training, the whole project finished commissioning in 28 days, ahead of the 38-day agreed construction cycle.

After 10 months continuous 24-hour operation, the customer fed back detailed operation data of MTW Trapezium Grinding Mill Plant: 1. Stable hourly output maintains 26-30t/h when producing 250-mesh limestone desulfurization powder, total single line output exceeds the sum of two old Raymond mills; 2. Single ton power consumption drops to 24kW·h, monthly electricity cost saved about 2,800 US dollars, annual power expenditure cut over 33,000 US dollars; 3. Uniform finished powder fineness, zero coarse powder leakage, successfully signed long-term annual supply contract with three local thermal power groups; 4. Workshop dust concentration meets Peru national environmental standard, all environmental penalties eliminated, workshop working environment greatly improved; 5. Wear parts replacement cycle extended to 7 months, annual spare parts maintenance cost reduced 22%; 6. Operators decreased from 6 to 2 per shift, annual labor expense saved nearly 20,000 US dollars.

In mid-2026, this Peruvian enterprise signed a secondary cooperation order with Mascot, planning to purchase another MTW175 Trapezium Grinding Mill Plant to expand limestone powder production capacity, which fully proves the stable performance and long-term cost-saving advantage of Mascot MTW series grinding equipment in large-scale mineral powder projects.
