Is MTW Trapezium Grinding Mill the Best Choice for Mineral Grinding?

1. Overview of MTW Trapezium Grinding Mill

The MTW Trapezium Grinding Mill, also known as the European-type trapezium mill, is developed by Mascot’s R&D team based on traditional grinding mill optimization and global market demands. It features a compact structure, modular design, and intelligent control, addressing pain points of old mills such as high energy consumption, low efficiency, and poor environmental performance.

1.1 Core Technical Parameters

• Capacity: 3-45 t/h
• Max. Input Size: 50 mm
• Finished Fineness: 0.038-0.4 mm (30-325 mesh)
• Applicable Materials: Limestone, calcite, marble, talcum, dolomite, bauxite, barite, etc.
• Motor Power: 55-160 kW

1.2 Working Principle

Raw materials are fed into the grinding chamber via a vibrating feeder. Under centrifugal force, grinding rollers press tightly against the grinding ring. The curved shovel blades lift materials into the gap between rollers and rings for grinding. Qualified powder is carried by airflow to the classifier, while coarse powder re-enters the grinding zone. Finally, fine powder is collected by the dust remover, meeting environmental standards.

2. Key Advantages of MTW Trapezium Grinding Mill

Compared with traditional Raymond mills, the MTW model integrates 6 patented technologies, delivering unmatched performance in efficiency, cost, and sustainability.

2.1 High Grinding Efficiency & Output

• Trapezoidal Working Surface: Increases grinding area by 30% vs. Raymond mills, boosting output by 20% under the same power.
• Curved Shovel Blade Design: Enlarges material grinding area, avoids dead angles, and improves powder yield.

2.2 Low Energy Consumption & Operation Cost

• Integral Bevel Gear Drive: Reduces transmission chain, minimizes energy loss by 15-20%, and ensures stable operation.
• Internal Thin Oil Lubrication System: Eliminates the need for an external lubrication station; extends bearing life and reduces maintenance frequency.

2.3 Eco-Friendly & Safe Operation

• Closed Negative Pressure System: Prevents dust leakage; equipped with a pulse dust remover, dust emission ≤30 mg/m³, meeting strict environmental standards.
• Wear-Resistant Alloy Components: Grinding rollers/rings made of high-chromium alloy (HRC ≥60), service life 1.7-2.5 times longer than traditional parts.

2.4 Compact Structure & Easy Maintenance

• Space-Saving Design: 20% smaller floor area than Raymond mills, reducing infrastructure investment.
• Modular Components: Split-type shovel blades allow only blade replacement, cutting maintenance costs by 40%.

3. Real-World Application Cases

Mascot’s MTW Trapezium Grinding Mill has been deployed in over 50 countries, serving diverse mineral processing projects.

Case 1: Limestone Grinding Plant in Indonesia

A local building materials company needed 20-25 t/h limestone powder (200 mesh) for cement production.

• Solution: MTW145 Trapezium Grinding Mill + pulse dust remover.
• Result: Output reached 28 t/h (exceeded target), energy consumption reduced by 22%, and dust emission complied with Indonesia’s environmental regulations.

Case 2: Gypsum Powder Production Line in Vietnam

A chemical plant required 15-20 t/h gypsum powder (325 mesh) for fertilizer additives.

• Solution: MTW115 Trapezium Grinding Mill + intelligent control system.
• Result: Stable operation for 2 years, finished powder fineness uniformity ≥98%, and maintenance costs reduced by 35%.

4. Related Recommended Equipment

To form a complete grinding production line, Mascot recommends the following supporting equipment:

1. Vibrating Feeder: Uniformly feeds raw materials into the mill, avoiding overload.
2. Bucket Elevator: Conveys materials to the silo, improving automation.
3. Pulse Dust Remover: Captures fine dust, ensuring eco-friendly production.
4. Powder Silo: Stores finished powder, facilitating packaging and transportation.

5. Frequently Asked Questions (FAQs)

Q1: What materials can the MTW Trapezium Grinding Mill process?

A1: It grinds non-inflammable and non-explosive minerals with Moh’s hardness below 9 and humidity <6%, including limestone, calcite, marble, talcum, dolomite, bauxite, barite, petroleum coke, quartz, iron ore, phosphate rock, gypsum, and graphite.

Q2: How to adjust the finished powder fineness?

A2: The fineness (80-425 mesh) is adjusted via the frequency converter of the classifier. Increasing the classifier speed produces finer powder; reducing speed yields coarser powder.

Q3: What’s the maintenance cycle of the MTW mill?

A3:

• Daily: Check lubrication oil level and dust remover pressure.
• Monthly: Inspect grinding rollers, rings, and shovel blades for wear.
• Quarterly: Replace lubrication oil and fasten loose bolts.
