These hammer mill known for the different features of hammer mill include:
- Unique and reliable design
- The bottom discharge hammer mill series pulverizers are highly effective as well as nonstop continuous pulverizing process.
- Compact size
- Dust free operation
- Ideal for dry crushing
- Increased production leading to faster return on the investments
- Hardened & fully machined shelving type blades thus less wear & tear
- All rotating parts are balanced for reducing friction losses and noise
Operating principle of bottom discharge hammer mill
The materials to be ground into the crushing chamber of hammer mill from feed hopper by gravity or through an auto feeder (optional) the beaters / blades inside the crushing chamber accelerate the material to a very high speed to the toothed liner placed at the upper half of the crushing chamber. Shearing pulverizes the material. The ground materials continuously discharge through screens placed at the bottom periphery of the crushing chamber and excess air filtered through a cotton balloon. Particle size varied using screens with different size holes.

Application of bottom discharge hammer mill
Hammer mills are exclusively meant for the grinding of sugar, bangle grams, maize, pulses, and a large scale basis.
Construction of bottom discharge hammer mill
Hammer mill made from heavy duty mild steel fabricated body. Grinding chamber lined with serrated wear plates, which protects the body from wear and tear. Grinding is done by a set of swinging blades or hammers on a balanced rotor. A screen classifier forms the lower half of the grinding chamber.
