A Universal Mill provides high performing one-pass fine grinding. This type of Kemutec Mill is ideal for when a controlled reduction in particle size is needed, coupled with a high degree of fineness.
Universal Milling Machines are commonly used in the fine-food processing industries, such as those who grind spices, salt and flour. Due to its performance, it is also a popular choice of Mill for those working in the powder sectors, including chemicals and pharmaceuticals.
To allow for maximum process performance and minimal downtime, the KEK Universal Mill is available with a variety of interchangeable grinding media, such as turbine and screen grinding components, as well as pinned disc grinding media.
Specially designed to provide capabilities of unsurpassed performance and controlled fine-milled particle size, this type of Mill processes material to a D50 of 100μ to 20μ.
Another design advantage is that it allows for flexible system integration. As an effect, fitting the mill is easy in both new production lines or existing, while the integration of a hinged and interlocking door enables easy access for simple maintenance and inspection.
To ensure minimal moisture absorption and to maintain material integrity, the Universal features a specialised closed-loop ‘airless’ design.
For heat-sensitive product, optional temperature control and full cryogenic grinding capabilities are available. This also helps grind materials that are difficult to process at ambient temperatures, by first cooling the material to a rate in which it can then be successfully ground.

The KEK Universal Mill is a high performing milling machine, with interchangeable grinding media to maximise processing versatility and capability. Benefiting from a closed-loop Airless milling design, the Universal Mill ensures minimal moisture absorption.
Our KEK Universal Mill can be supplied as machine only or as a complete milling system.
Kemutec’s KEK Universal Mills benefit from varied and versatile system design and capabilities. They can engineered to suit the specific demands of the client’s applications.
The Universal Mill can be sited at elevated levels or at ground level and linked to the milled powder collection. This is by either an integral hopper or a remote filler – receiver (see below).
In addition, KEK Universal Mills benefit from customised process design options, typically these are:
Note: Intert means
Replacing combustible gases and air in a process machine, with an inert gas such as nitrogen, CO2”. Most common application is to remove air, which contains 21% oxygen and therefore makes air a good fuel to burn after ignition. No air helps ensure no flame or explosion.
KEK Universal Mills effectively grind material ranging from soft to medium, to hard and non-abrasive powders and granules.

Temperature Controlled Grinding
Temperature controlled milling involves the use of liquid nitrogen as a cooling agent. This is applied to the mill and collection system. This milling system is often adopted to improve processing properties of heat sensitive materials or, give a specified product output from the mill, where it is essential to eliminate temperature pick up during normal milling. Example being control of mill temperature from ambient mill temperatures to -5°C.
Cryogenic grinding systems also involve the addition of nitrogen, but the temperatures are much lower. Cooling is applied to the mill system and the feed product. The aim 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 very finely.
Cool and cryogenic grinding also provides the added benefit of inert explosion protection.
