Which MTW Grinding Mill Fits Your Production Line? Full Model Comparison in One Table

Choosing a grinding mill is not about picking the biggest or the cheapest machine — it is about matching the equipment to your production reality. Oversize a mill and you waste capital; undersize it and you cap your growth. The MTW Trapezium Grinding Mill series from Mascot Heavy Industry covers the full capacity spectrum from 3 t/h to 50 t/h with just four models: MTW110, MTW138, MTW175 and MTW215. This guide compares all four models side by side on the factors that actually decide your choice — capacity, feed size, power economics and application fit — so you can locate the right model in one look.

1. Four Factors That Decide Your Model

Every production line is different, but the model decision always comes down to four questions:

• Target capacity (t/h): How many tons of finished powder do you need per hour? This is the primary selector.
• Raw material feed size (mm): The max feed size grows from ≤30mm to ≤45mm across the series, which decides whether you need an extra pre-crushing or screening stage.
• Required fineness: All four models adjust steplessly between 0.038-0.2mm (80-425 mesh), so fineness is rarely the deciding factor between models.
• Power economics: Larger models cost more to buy and run — but they also deliver more tons per kilowatt. The sweet spot differs by production scale.

2. The Full Model Comparison Table

The table below is the complete picture of the MTW series: roller size, grinding ring dimension, feed size, output size, capacity and the power configuration of main mill, powder classifier and blower for every model.

3. Efficiency Analysis: Which Model Delivers the Most Tons per Kilowatt?

Beyond raw capacity, the smarter question is efficiency — how many tons you get for every kilowatt of main motor power at maximum output. The calculation reveals where the real value sits:

The data shows why MTW138 is the best-selling model worldwide: it delivers 20 t/h with a 90kW main motor, the same 0.22 t/h per kW efficiency as the much larger MTW175, but at a far lower entry investment. For medium-scale producers, it is simply the hardest-working value in the series. At the top end, MTW215 pushes the ratio to 0.23 t/h per kW, making it the most economical choice for bulk production where every ton of output counts.

4. Model by Model: Who Should Choose Which?

4.1 MTW110 (3-10 t/h) - The Compact Starter

With a 55kW main motor and a 1100x210mm grinding ring, the MTW110 fits small-scale plants, pilot projects and startup grinding businesses. If your target output is below 10 t/h, this is the economical answer.

4.2 MTW138 (6-20 t/h) - The Medium-Plant Benchmark

The 1380x260mm grinding ring accepts feed up to 35mm and delivers the best capacity-to-power ratio in the series. It is the default recommendation for regional powder producers processing limestone, calcite, barite, talc or gypsum at 200-325 mesh.

4.3 MTW175 (10-35 t/h) - The Large-Line Workhorse

Its 520x300mm rollers and 1750mm ring accept feed up to 40mm, which matches the discharge size of a standard jaw crusher and saves you an intermediate screening stage. Field data from a Southeast Asian limestone plant shows a stable 31 t/h at 250 mesh — see the case in Section 6.

4.4 MTW215 (20-50 t/h) - The Maximum-Capacity Flagship

With a 640x340mm roller, a 2150x340mm ring and feed up to 45mm, it is built for centralized powder production bases and large mining complexes where single-line throughput determines unit cost.

5. Feed Size: The Detail That Changes Your Whole Line

Capacity gets most of the attention, but feed size often decides the total line design. MTW110 requires feed no larger than 30mm; MTW138 accepts 35mm; MTW175 accepts 40mm; and MTW215 accepts up to 45mm. If your crusher discharges 40mm material, choosing MTW110 or MTW138 means adding a screening or secondary crushing step — an extra cost that can be larger than the price difference between models. Always match the mill's feed limit to your crusher output, not the other way around.

6. Proof Point: MTW175 in Real Production

A building materials enterprise in Southeast Asia replaced its traditional mills with a Mascot MTW175 complete line in August 2025, processing limestone at ≤40mm and ≤5% moisture into 250-mesh powder. After 28 days of on-site installation and commissioning, the line has run stably for over 10 months with confirmed results: average output of 31 t/h (above the 28-32 t/h design target), 99.6% finished powder pass rate, 22% lower energy consumption per ton, and wear parts lasting over 10 months. The customer ordered a second MTW line in April 2026. The same machine that tops the comparison table is delivering these numbers in the field.

7. Five Questions to Ask Before You Order

1. What is your target output in tons per hour? (This is your primary model selector.)
2. What is the maximum feed size coming out of your crusher? (Match it to the model's feed limit.)
3. What fineness does your market require? (80-425 mesh is adjustable on every model.)
4. Is your raw material moisture below 6%? (Above that, pre-drying is required.)
5. Do you plan to expand production in 2-3 years? (Choosing one model higher often saves a second purchase.)
