Conical Screen Mills
The Uni-Mill conical screen mill draws upon Hanningfield’s wealth of experience in size reduction for the process industries.
Conical screen or 'cone-milling' is ideal for achieving a fine, uniform particle size. By combining high throughput and high efficiency, the low energy Uni-Mill is perfect for the pharmaceutical, food, chemical and consumer goods industries.
The Uni-Mill is designed and manufactured by Hanningfield Process Systems at our UK Headquarters.

Profile
The Uni-Mill conical screen mill balances performance with simplicity, to provide a solution that guarantees a high throughput but is easy to operate, clean and maintain. This durable design makes the Uni-Mill extremely reliable, perfect for even the most demanding of processing requirements.
The Uni-Mill is suited to dry, wet or fine milling in the pharmaceutical, food, chemical and consumer goods industries. The mill can easily be adapted for use on different products, simply by changing the granulating screen, presenting a cost-effective solution to your size reduction requirement.
The Uni-Mill is available in various sizes to ensure all equipment is tailored to a customer’s specific requirements.

Method of Operation
Unprocessed material is loaded into the product inlet of the Uni-Mill by hand, gravity feed or vacuum transfer. The material then passes into the milling chamber where a rotating impeller forces the unprocessed material through a stationery cone-shaped screen by a vortex action. The material is instantly reduced in size as it passes through the holes in the screen.
By changing a combination of screen, impeller shape and speed, the finished milled particle size can be carefully controlled. Most important for hygienic requirements, such as those in pharmaceutical and food production, there is no metal-to-metal contact between the impeller and screen.
