3. Detailed Overseas Customer Application Case of MTW Trapezium Grinding Mill
In early 2025, one large building material group from Uzbekistan (Central Asia) planned to build a new limestone fine powder production line for local cement additive and dry mortar raw material production, after comparing 6 domestic and Chinese grinding equipment suppliers for 3 months, the customer finally signed full-set procurement contract with Mascot Heavy Industry for one complete MTW175 type MTW Trapezium Grinding Mill production line.
Basic Project Information: Raw material: Limestone (raw feeding moisture 7.2%, Moh hardness 3.2); Required finished product: 250mesh uniform limestone powder for dry mortar; Target stable hourly output:18t/h; Project construction cycle requirement: finish installation & commission within 40 working days after equipment arrival at Tashkent port.
Complete Line Equipment Composition: Main host: MTW175 MTW Trapezium Grinding Mill; Auxiliary devices include B500×7m belt weighing feeder, TH400 bucket elevator, LQM72-6 pulse dust collector, LSY273 screw conveyor and full-set PLC centralized control cabinet, all auxiliary equipment parameters as shown in below table:
| Auxiliary Equipment Name | Model Spec | Matching Power(kw) | Core Function |
|---|---|---|---|
| Belt Scale Feeder | B500×7m | 3.0 | Variable frequency quantitative feeding, weighing accuracy ±0.8% |
| Chain Bucket Elevator | TH400×11m | 5.5 | Vertical raw material lifting to buffer silo |
| Pulse Dust Collector | LQM72-6 | -- | Full-line dust collection, exhaust compliance emission |
| Screw Conveyor | LSY273×4m | 3.0 | Finished powder sealed conveying to stock bin |
Project Implementation & Post-operation Effect: Mascot arranged two senior mechanical engineers to fly to Uzbekistan to guide on-site installation, equipment debugging and local worker operation training after all MTW Trapezium Grinding Mill and matched auxiliary machines arrived at destination; the whole line passed formal production acceptance within 36 days, ahead of customer required schedule. After over 12 months continuous stable running till now, actual average hourly output reaches 19.2t/h (surpass designed 18t/h index), finished powder pass rate of 250mesh reaches 97.5%. Compared with customer’s previous old Raymond production line, the MTW Trapezium Grinding Mill system cuts power consumption per ton finished powder by 32%, on-site labor reduces from 5 workers to 2 operators, annual maintenance expense drops about 17%. The Uzbekistan client has placed repeat order for one set of MTW138 MTW Trapezium Grinding Mill line in April 2026 for its branch factory expansion project.
4. Related Grinding Equipment Recommendation Matched with MTW Trapezium Grinding Mill
According to different raw material feeding size and pre-crushing requirement of clients’ MTW Trapezium Grinding Mill production line, Mascot recommends three matched upstream crushing & grinding machines to form complete closed-loop processing system:
1. Jaw Crusher: Small & medium PE series jaw crusher for primary coarse crushing of raw ore above 50mm, crush bulk raw material down to ≤45mm to fit maximum feeding limit of large-size MTW Trapezium Grinding Mill (MTW215).
2. Raymond Mill: 3R/4R small Raymond Mill is suitable for low-output small-scale powder project below 5t/h, acting as cost-effective alternative of mini-type MTW Trapezium Grinding Mill.
3. Ultrafine Vertical Mill: When clients need finished powder finer than 400mesh, vertical ultrafine grinder can be configured after MTW Trapezium Grinding Mill for secondary superfine deep processing.
5. Frequently Asked Three FAQs about Mascot MTW Trapezium Grinding Mill
FAQ1: Why finished powder of MTW Trapezium Grinding Mill becomes thicker suddenly during normal production?
Main causes: High-speed classifier impeller wears leading to coarse powder leakage or internal spring preload of grinding roller is insufficient. Troubleshooting steps: First inspect classifier impeller, replace worn parts if damaged; if impeller is intact, adjust internal spring pressure via PLC control panel to improve grinding tightness of MTW Trapezium Grinding Mill roller and ring to recover finished fineness standard.
FAQ2: What affects actual hourly output below rated capacity of MTW Trapezium Grinding Mill?
Three core influencing factors: Unstable feeding quantity caused by feeder blockage, serious abrasion of grinding roller/ring reducing effective grinding space, insufficient air volume from matched high-pressure blower. Solutions: Clean feeding chute regularly to guarantee uniform continuous feeding, replace severely worn roller and ring accessories, overhaul blower fan and clear blocked air pipeline of MTW Trapezium Grinding Mill circulating air channel.
FAQ3: What’s service cycle of core wear parts for different raw materials on MTW Trapezium Grinding Mill?
For low-abrasion raw material like limestone and calcite: Grinding roller & ring service life of MTW Trapezium Grinding Mill reaches 2200-3200 working hours; For high-abrasion mineral like quartz sand and emery: Core wear parts lifespan shortens to 900-1400 working hours; Regularly control feeding grain size within equipment specified range and keep stable feeding speed can extend spare part service life by 15%-20% effectively.
