INTRODUCTION

MTW series trapezium mills are a perfect grinding machine, which could produce 80-400mesh fine powder with large capacity. The biggest model could give 50tph capacity with less powder consumption.
Due to its stable performance, MTW series mills are widely used for making fine powder, which are mostly used for agriculture, chemical, paint, wall putty, steel plant, water treatment, etc.

PRODUCT ADVANTAGES

Less Occupied Area & Less Investment

MTW series trapezium mill has its own production system from bulk material to finished powder, with less investment in building plant and foundation.

60% Lower on Consumption than Ball Mill

MTW series trapezium mill has an energy consumption of more than 60% lower than that of the same grade of ball mill under ideal working conditions.

Adjustable Output Fineness

MTW series trapezium mill adopts modular impeller adjustment device, which can produce products with different fineness only by changing impellers.

Higher Induced Air Efficiency

MTW series trapezium mill adopts high efficiency impeller fan, which improves the efficiency of air induction from 62% to 85%.

FAQ

Customers find grinding fineness unstable, affecting separation. How is it adjusted?

Fineness depends on grinding time, media load and closed-circuit classification. Adjust media, stabilize grinding and use hydrocyclone classification to stabilize it.
Is a mining ball mill suitable for copper and iron ores?

Yes. It grinds copper, lead, zinc, gold, iron and other metal ores, a common machine in ore-dressing plants.
Customers care how grinding fineness affects separation. How to explain?

Fineness directly affects separation: suitable fineness with good liberation raises recovery in flotation or magnetic separation; insufficient fineness lowers recovery.
A customer needs a grinding machine for an ore-dressing plant. Is a mining ball mill suitable?

Yes. A mining ball mill is designed for beneficiation, grinding crushed ore to suitable fineness, and is the key stage between crushing and separation.
Should mining grinding be dry or wet?

Mineral processing overwhelmingly uses wet grinding, conveying pulp with less dust and suiting subsequent separation; dry grinding is for special processes, so wet is usual.
How does a mining ball mill form a closed grinding circuit?

It is usually paired with hydrocyclones or classifiers: ball-mill discharge goes to classification, qualified pulp enters separation, and coarse particles return to the ball mill, forming a closed loop.
