Universal Mill | high performance fine grinding

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.

Features and Benefits

• Interchangeable grinding media for maximum process performance and minimal downtime
• High performance, for superior fine grinding
• Milled particle size range down to a  D50 – 100μ to 20μ
• Can be custom integrated into an existing system, for maximum design flexibility
• Closed-loop “airless” milling, for minimal moisture absorption
• Temperature controlled and cryogenic grinding available

Our KEK Universal Mill can be supplied as machine only or as a complete milling system.

Range Details

• Large range available from lab all the way through to production
• 3 hp to 125 hp
• Interchangeable grinding media options include turbine and screen, pinned disc, and rib track

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.

Design Options

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:

• Temperature controlled grinding
• Cryogenic milling
• Inert milling
• Explosion protection relief through bursting panels
• Explosion suppression with a quench or suppression system
• Explosion containment with 10 bar PSR design
• System inerting by replacing combustible gases and air with inert gas such as nitrogen.
• Closed loop milling, fine grinding without the need for filtration
• Compact design changes
• Minimal moisture uptake in milled powder
• 10 bar PSR capability

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.

Typical Applications Include:

Food Industry

• 6X and 10X Grade powdered sugar
• Microfine salt
• Rice flour
• Wheat flour
• Casein and whey powder
• Spices

Pet Food Industry

• Size reduction of ingredients prior to mixing and extrusion. Especially important for the small fish food applications. For a finer grind however, we would recommend the PPS Air Classifier Mill

Pharmaceutical Industry

• Fine powder grinding
• Fine powder de-agglomeration
• Dry granulation

Chemical Industry

• Sodium bicarbonate
• Trona
• Sulphur
• Nitrates
• General fine powder grinding

Special Applications

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

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.
