Applicable Materials:MTW Trapezium Grinding Mill is applied in mining, construction materials, chemical and metallurgy industries for grinding non-flammable and non-explosive minerals with Mohs hardness below 9.3.
MTW trapezoidal grinding mill is an ideal grinding equipment for mining, building materials, chemical industry, and other industries due to its high efficiency, energy saving, and strong adaptability. Whether it is non-metallic mineral powder processing or industrial solid waste recycling, it can provide stable and reliable solutions!
Core features:
MTW110 is suitable for small and medium-sized production lines, with moderate processing capacity, suitable for occasions where the output requirements are not very high.
MTW138 has improved processing capacity compared to MTW110T, suitable for medium-sized production lines.
MTW175 has further enhanced processing capacity, suitable for large production lines, and can efficiently complete the grinding of a large number of materials.
As an upgraded product of the traditional Raymond mill, it has the advantages of high efficiency, energy saving and environmental protection, durability, and easy maintenance.
Advantages and Features
Efficient grinding - trapezoidal grinding roller and grading system
• The curved trapezoidal grinding roller design increases the contact area, and the rolling efficiency is 30%-50% higher than that of the traditional Raymond mill, and the finished product fineness is uniform (80-400 mesh adjustable).
• The dynamic turbine classifier has a built-in high-precision grading wheel to avoid over-crushing, and the fineness can be flexibly adjusted (such as 325 mesh D97 pass rate ≥95%).
Energy saving and consumption reduction - low energy consumption and long life
• The energy consumption of the main machine is reduced by 20%-30%, and the bevel gear integral transmission and thin oil lubrication system are adopted, which saves electricity significantly.
• Wear-resistant parts (grinding roller/grinding ring) are made of high chromium alloy or ceramic composite materials, with a life of 800-1200 hours and lower maintenance costs.
Intelligent and stable - automatic control
• PLC intelligent control system monitors current, temperature and other parameters in real time, automatically adjusts feed amount and grinding force, and reduces manual intervention.
Environmental compliance - low emissions and low noise
• The pulse dust removal system has dust emissions of <30mg/m³, which complies with EU CE and China GB16297 standards.
• The closed operation noise is <75dB (traditional >85dB), which is suitable for areas with strict environmental protection requirements.
Working Principle
What Is The Working Principle Of The MTW Trapezium Grinding Mill
Material crushing and transportation: Large pieces of material are first crushed to the required particle size by the jaw crusher, and then the materials are sent to the storage hopper by the elevator. Then, the materials are uniformly and quantitatively continuously fed into the main milling chamber through the vibrating feeder for grinding.
Grinding process: In the main grinding chamber, the material is subject to the combined action of the grinding roller and the grinding ring. The grinding roller device not only rotates around the central axis but also revolves around the grinding ring. At the same time, the grinding roller itself rotates due to friction. This movement mode causes the material to be strongly impacted and ground between the grinding roller and the grinding ring, thereby being crushed into fine powder.
