Process:
Milling & GrindingThe Hamex® Fast Screen Exchange Hammer Mill grinds soft to medium-hard products with a fineness from 150 microns to about 3 mm. With a maximum speed of 1800 rpm, the Hamex® Fast Screen Exchange Hammer Mill is an energy-efficient and quiet solution. The RPM is lower than the Hamex® Hammer Mill, but because the tip speed of the hammers is not reduced, you can achieve a similar grind at lower energy consumption.
The Hamex® Fast Screen Exchange Hammer Mill allows sifter changes to be made while the rotor is still spinning. This results in ten minutes saved sifter change. In addition, the Hamex® Fast Screen Exchange Hammer Mill is equipped with large inspection hatches that provide quick and easy access for inspection, cleaning, and maintenance.
Hamex® Hammer Mills are the result of years of innovation and continuous development to make them even more efficient, productive, reliable, energy-efficient, safe and quiet. All Hamex® Hammer mills are designed as follows:
Depending on the characteristics of the product to be sifted, single hammers, double hammers or T-hammers are used. Normally the rotor in the hammer mill must come to a standstill before the sifter can be changed. It takes an average of ten minutes to do so. To save this time, Dinnissen has developed a semi-automatic sifting system. In the Hamex® Fast Screen Exchange Hammer Mill, the sifter in its sifter holder is automatically driven out of the machine, after which the operator can quickly exchange or inspect the sifter manually. During this operation, the rotor can keep rotating as usual. With regular product changes, this system provides significant time savings.
In the hammer mill, freely suspended hammers swing around at high speed. This creates centrifugal force which crushes the grinding material against the crushing plates inside the grinding chamber. These shredders have been specially developed to crush the material as efficiently as possible. The crushed product then leaves the hammer mill through the replaceable sifter. Depending on the properties of the product to be ground, single hammers, double hammers or T-hammers are used.
