Franklin Miller's size reduction processors play a vital role in the processing of food, food ingredients, food waste, food disposal,de-packaging, recycling and more. Chances are if you have a product or material that needs crushing, grinding, shredding or separating, we have a machine or system that will meet or exceed your expectations.

By using a roller mill, or adopting roller grinding principles as part of the feed mechanism on entry to the hammermill, the raw material is partially ground at that point, which then allows the hammers and screens in the grinding chamber of the hammermill to be fully effective, with often excellent grinding efficiency results.

A roller mill is a grinding machine used to accomplish size reduction of different types of grains and other materials. Different types of roller mills for sale in Kenya, perform different functions and therefore you need to know what you will be using the roller mill most for before purchasing one.

Size Reduction. Size reduction is a process of reducing large solid unit masses into small unit masses, coarse particle or fine particles. Size reduction process is also referred to as commination and grinding. When the particle size of solid reduced by mechanical means it is known as milling. Size reduction operation divided into two category –.
