Hammer Mills

In our industry there is a saying that if you have a hammer mill, you have a business.
Drotsky says: “If you have a Drotsky hammer mill, you are guaranteed a successful business”
Milling is the process of breaking up or crushing material into smaller pieces to make it more palatable for human and animal consumption. Through the years Drotsky sold more than 60 000 hammer mills in Southern Africa and the advantage of this unconventional designed hammer mill is that the milled product comes out of the machine at a far higher rate than the old conventional designs.

How does a Drotsky hammer mill work?
Material is fed into the milling chamber via a gravity feed hopper having an adjustable slide to control the feed material. In the milling chamber the material is struck by hammers (rectangular pieces of hardened steel) attached to rotor arms that are attached to a shaft. This rotor rotates at a high speed inside the milling chamber and the material is crushed by repeated hammer impacts.

A perforated metal screen covers the full circle of the milling chamber and this allows properly sized material to pass as finished product while the course material remains in the milling chamber for further grinding. The screen size determines the finished size of the product.

Advantages of a hammer mill

For the small farmer or any other user wishing to add value to his operation, the small hammer mill presents a cost effective, sensible and practical option. The benefits are low capital and low running costs, minimal maintenance, faster milling times and more hygienic milling conditions.

The user can immediately start earning an income with the hammer mill. Where an organisation or group uses it, it will have an immediate effect on the quality and speed with which the milled product can be delivered.

These Drotsky machines are designed and built in Africa for African conditions. For a small investment a big return can be obtained in terms of monetary advantages if used as an income producing asset, or in the improvement in the quality of life if supplied to groups or communities to mill for food for their daily needs.
