The KEK Universal Mill provides high-energy one-pass fine grinding. Available with a variety of interchangeable grinding media, the KEK Universal Mill is capable of unsurpassed, versatile milling performance with a controlled milled particle size range – D50 of 100μ to <20μ. Process customisation includes closed-loop mill design, 10 bar containment systems, temperature controlled grinding, and full cryogenic grinding.
KEK Universal Mills are high-energy mills, with interchangeable grinding media to maximise processing versatility and capability.
Features and Benefits
The KEK Universal Mill is supplied as machine only or complete milling system
KEK Universal Mills benefit from varied and versatile system design capabilities, which can be customised to suit the demands of the individual applications.
The mill can be sited at elevated levels or at ground level and linked to the milled powder collection by either an integral hopper or by a remote filler – receiver (see below).
In addition, KEK Universal Mills benefit from customised process design options, typically including:
KEK Universal Mills are high capacity fine grinders for the size reduction of soft to medium hard and non-abrasive powders and granules. Clean Room KEK Universal Mill
Typical Applications include:
Temperature Controlled Grinding
Temperature controlled milling involves the use of liquid nitrogen as a cooling agent which is applied to the mill and collection system. This system is often employed to either improve processing properties of heat sensitive materials or give a specified milled product output from the mill where it is essential to eliminate temperature pick up during normal milling i.e. control of mill temperature from ambient mill temperature to -5°C.
Cryogenic grinding systems also involve the addition of nitrogen but the temperatures are much lower and cooling is applied to the mill system and the feed product. The object is to embrittle products that are impossible to impact mill at ambient temperatures. By cooling them to temperatures of -150° C, it is possible to grind problem materials finely.
Cool and Cryogenic grinding will also provide the added benefit of inert explosion protection.
