Pin mill for fine grinding of sticky materials
Achieve ultra-fine grinding of challenging materials with high speed and precision, ensuring seamless integration into continuous production lines for processing powders and granules.
Processes and Grinds Complex Materials Efficiently
The Contraplex CW II from Hosokawa Alpine is a versatile fine impact mill designed to tackle the challenges of grinding and mixing complex materials, including sticky, heat-sensitive, and greasy substances. This dual-driven pin disc mill operates with counter-rotating discs, achieving relative speeds of up to 240 m/s for exceptional fineness. Ideal for applications across chemicals, pharmaceuticals, and food industries, it handles an array of end-products like lithium-ion battery anodes, spice blends, and synthetic rubber.
With a robust belt drive system, the Contraplex CW II ensures optimal energy efficiency and performance, while the wide-chamber housing prevents material build-up and blockages. The equipment offers easy integration into continuous production lines, supported by PLC controls for automation and seamless operation.
Constructed from mild or stainless steel, the machine is suitable for various processing environments, offering special options for pharma and coating applications. The design facilitates easy cleaning and maintenance, featuring a hinged mill door for swift access. Additionally, it supports customization in disc speeds and rotational direction to meet specific grinding conditions.
Ideal for manufacturers seeking high precision and adaptability, the Contraplex CW II meets rigorous industry standards, with optional configurations available for enhanced performance and specific requirements.
