MTW Series European Trapezium Grinding Mill: Evolution of Traditional Technology
The MTW Series European Trapezium Grinding Mill represents a significant advancement over conventional grinding mills, incorporating international advanced technologies based on extensive research and customer feedback from more than 9,500 installations. This mill features several proprietary innovations that distinguish it from traditional equipment, including cone gear whole transmission, inner oil absorption lubrication system, and arc air flue design.
The unique wear-proof perching knife design incorporates combined-type shovel blades that significantly reduce wearing parts costs. During maintenance, only the blade requires replacement rather than the entire assembly. The curved shovel blades are engineered to optimize feeding angle and extend the service life of rollers and rings, ultimately reducing long-term operating expenses. The arc air duct design prevents air energy loss while ensuring efficient material transportation, with high-strength guard plates protecting the working surfaces from premature wear.
With an input size capacity of 0-50mm and output fineness ranging from 30-400 mesh at throughput rates of 3-40tph, the MTW mill demonstrates remarkable versatility across various mineral processing applications. The cone gear transmission system achieves higher mechanical efficiency while saving valuable floor space, contributing to lower initial investment costs. The unobstructed wear-resistant volute design further enhances wind-driven transmission efficiency within the mill while minimizing maintenance requirements for material handling components.
LM Vertical Roller Mill: Integrated Processing Solution
SBM's LM Vertical Roller Mill addresses critical industry challenges of low output and high energy consumption through an integrated design that combines crushing, drying, grinding, powder separation, and transportation functions within a single unit. This comprehensive approach results in a system that occupies approximately 50% of the space required by conventional ball-milling systems while offering superior operational efficiency.
The vertical configuration enables direct grinding action where rollers contact materials on the grinding plate without direct metal-to-metal contact between components. This design principle, combined with high-quality materials for rollers and grinding plates, results in significantly reduced wear and extended service life. The energy consumption is notably lower than traditional ball-milling systems, with documented reductions of 30-40% under comparable operating conditions.
Operating with input sizes up to 50mm and producing powders ranging from 30-400 mesh at capacities from 3-400tph, the LM Vertical Roller Mill accommodates both small-scale and large-scale production requirements. The integrated expert automatic control system enables seamless switching between remote and local control modes, simplifying operation and reducing labor costs. Environmental performance is enhanced through stable operation with minimal vibration, low noise emission, and completely sealed negative-pressure operation that prevents dust spillage.
SCM Ultrafine Mill: Precision in Fine Grinding
As market demands for finer powder specifications continue to increase, conventional grinding equipment often proves inadequate. SBM's SCM series ultrafine grinding mill specifically addresses this gap with capability to produce powders adjustable from 325 to 2500 meshes, with single-pass fineness reaching D97≤5μm. Through rigorous testing at geological research institutes, the mill has demonstrated capability to achieve fineness levels up to 2500 meshes in specific applications.
The technical advantages of the SCM ultrafine mill include remarkably high output with low energy consumption, achieving more than double the capacity of jet mills while reducing energy usage by approximately 30%. The intelligent control system incorporates automatic feedback mechanisms that ensure fast and stable conversion to finished products while minimizing manual intervention. Frequency-conversion control enables precise adjustment of product specifications, while the efficient vertical turbine powder classifier ensures accurate particle size distribution without coarse powder spillover.
Durability is enhanced through heavy rotor design and specialized materials for rollers and rings, providing several times the service life of conventional components. The grinding chamber employs a bearing-free screw design that maintains stability through balanced treatment, eliminating vibration during operation. Environmental considerations are addressed through efficient dual powder collection combining cyclones and pulse dust collectors, achieving dust collection efficiency significantly exceeding international standards.
