Products Description
MTW Series European Trapezium Grinding Mill is a new-generation grinding equipment independently developed by our factory. We introduced advanced European powder grinding technology and combined decades of machinery manufacturing experience to launch this model. Its core components adopt trapezoidal grinding rollers and trapezoidal grinding rings, which effectively solve the pain points of traditional Raymond mills, such as low grinding efficiency and short service life of wear-resistant spare parts.
Compared with conventional old-style Raymond mills, this machine achieves a 30%-40% higher production capacity while cutting comprehensive energy consumption by 20%-30%. It has become the mainstream upgraded alternative for non-metallic mineral powder processing. The whole unit is equipped with multiple mature structures including integrated bevel gear transmission, built-in thin oil lubrication system, curved low-resistance air duct and variable-frequency cage classifier, delivering stable operation and easy maintenance.
It is widely applied in building materials, chemical industry, metallurgy and mining sectors, processing all kinds of ores with Mohs hardness ≤9 and moisture content below 6%. The fineness of finished powder can be adjusted from 80 mesh to 425 mesh, making it perfectly matched with complete large-scale heavy calcium carbonate production lines.
Working Principle
The basic grinding principle of the MTW European Trapezium Grinding Mill is similar to that of the traditional Raymond Mill, yet its overall structure is comprehensively upgraded and optimized. The unique trapezoidal grinding rollers expand the contact area with the grinding rings, boosting grinding efficiency and enabling even wear to extend the service life of wear-resistant parts. Equipped with pressurized spring assemblies, the machine can process materials with higher hardness. Its classifier adopts variable-frequency speed regulation to realize precise and convenient adjustment of finished product fineness. The whole machine operates under negative pressure and airtight conditions, paired with shock absorption and noise reduction components, resulting in low dust emission and low operation noise, fully complying with environmental protection standards.
Performance Features
Adopts trapezoidal grinding rollers and rings for larger contact area, higher grinding efficiency and longer service life of vulnerable components.
Integrated bevel gear transmission with built-in thin oil lubrication reduces transmission loss, ensures long-lasting bearing performance and eliminates the need for an independent lubrication station.
Curved low-resistance air duct delivers smooth airflow to avoid material blockage; matched with high-efficiency centrifugal fans with high air pressure for stable long-distance powder conveying.
Variable-frequency cage classifier supports adjustable fineness ranging from 80 mesh to 425 mesh with high classification accuracy and no coarse powder leakage.
Equipped with integral shock-absorbing base and noise reduction cover, cutting operating noise by 20-30 dB compared with traditional Raymond Mills.
The whole system runs in a fully closed negative-pressure environment with supporting dust removal devices to prevent dust leakage and meet environmental protection requirements.
Modular integrated design facilitates disassembly, assembly and maintenance, greatly shortening equipment downtime.

Application Scenarios
It is widely applied in industries including building materials, chemical engineering, metallurgy, mining and power plant desulfurization. It is suitable for grinding non-metallic minerals with Mohs hardness ≤9 and moisture content below 6%, such as limestone, calcite, heavy calcium carbonate, talc, gypsum, barite, feldspar, marble, dolomite, kaolin and bentonite. It is especially ideal for large-scale production lines of heavy calcium powder and desulfurization limestone powder.
FAQ
What are the differences between the MTW European Trapezium Grinding Mill and the traditional Raymond Mill?
The MTW European Trapezium Grinding Mill features a full set of upgraded configurations including trapezoidal grinding rollers and rings, bevel gear transmission, built-in thin oil lubrication, variable-frequency classification and noise & vibration reduction. Its output increases by 30%-40% while energy consumption drops by 20%-30%. It runs quieter with more durable spare parts, serving as an ideal upgraded replacement for traditional Raymond Mills.
Can the MTW European Trapezium Grinding Mill process materials with high moisture content directly?
This machine is designed for raw materials with moisture content ≤6%. If the feedstock contains higher moisture, it is recommended to pre-dry the materials with a rotary dryer, or select a vertical roller mill with integrated drying function.
What is the finest powder that the MTW European Trapezium Grinding Mill can produce?
The standard model can produce finished powder with adjustable fineness from 80 mesh to 425 mesh. If ultra-fine powder up to 2500 mesh is required, our ultra-fine ring roller grinding mill is recommended.
Do you provide on-site installation and commissioning services?
We can arrange professional engineers to guide on-site installation, commissioning and operator training. The equipment comes with a 12-month full machine warranty and lifelong technical support.
