Engineering
Fine grinding (milling), micronizing and particle size classification (fractionation). We offer plants from laboratory size through to high capacity production units. Units may be purchased as turnkey projects.
Exfoliation
For the expansion or exfoliation of vermiculite or perlite, we offer vertical kilns. These kilns boast an energy efficient design and labour efficient operation. Exfoliation units may be purchased as turnkey projects.
Micronized Milling & Manufacturing (Pty) Ltd
The Kenwatt range has continuously evolved over two decades of experience in the field of size reduction of solid substances (crushing, milling and micronizing). From attapulgite to zirconium, foodstuffs, polymers, chemicals and fibrous materials, the Kenwatt range has demonstrated consistently efficient results.
THE KENWATT MICRONISER
(Refer to Above Drawing - Kenwatt Milling/Micronising System)
- Custom designed affordability! Efficient one-step milling and micronizing of minerals, foodstuffs and chemicals. Environmentally friendly! Dust-free operation through maintaining system under negative pressure. Exceptional ease of use.
- Available in Laboratory Unit size up to 75 kW main motor drive configurations.
Micronising and Coupled Classification - A World Beater!
The Kenwatt range of micronizers have built-in particle size classifiers. This provides efficient one-step particle size classification and reduction and results in less maintenance and lower operating costs per ton of output. Kenwatt Micronizers are also constructed from state of the art materials. Whether you require a stand alone micronizer, or a complete turnkey installation be sure to contact us and gain a competitive edge!

Particle Fractionators
THE KENWATT FRACTIONATOR
(Refer to Above Drawing – Kenwatt Fractionator System)
- Due to our unique rotor design no short-circuiting of oversized particles is possible! Precise particle sizing cut-off points. Custom designed affordability for fractionation and powder classification. Excellent split efficiencies of materials. Environmentally friendly! Dust free - through maintaining system under negative pressure. Ease of operation.
- Available in three models, including a laboratory sized unit.
Precise Dry Particle Sizing!
The Kenwatt range of fractionators has been developed to offer precise particle sizing cut-off points, combined with exceptional production efficiency. Ease of operation and robust design ensure low maintenance, trouble-free operation, even in the harshest conditions.
Kenwatt fractionators can be coupled to an existing milling or grinding circuit, or can operate as stand alone systems with a fine particle feed. Kenwatt fractionators are suited to a wide range of applications including chemicals, foodstuffs and minerals. Oversized separated particles can be optionally returned to the feed or milling circuit, or bagged-off as a separate secondary product. Kenwatt fractionators are also particularly suited to fines removal and reducing dust concentrations on powdered materials.
