Industrial crushing, grinding and pulverizing equipment

Industrial Crushing grinding and pulverizing equipment


Techno wings hammer mill offers three series of hammer mills ideally suited for processing a wide variety of spices and dried herbs. Each series will produce the exact desired finished size while preserving aroma and volatile oil qualities.
With more than thirty models to choose from, our expert engineering team will match you with the right mill to suit your material and production goals.


Our clients can avail from us a qualitative range of hammer mills that are used for shredding different material into finer particles. Hammer mills are primarily steel drums that contain a horizontal cross-shaped rotor mounted with pivoting hammers, which can freely swing on either ends of the cross. While the material is fed into the feed hopper, the rotor placed inside the drum is spun at a high speed. Thereafter, the hammers on the ends of the rotating cross thrust the material, thereby, shredding and expelling it through the screens fitted in the drum.
We take great pride in our ability to custom tailor our equipment to the exact specifications of our customer, offering free test grinding to prove our equipment's capabilities and custom engineering services without the custom price tag. Our equipment is renowned for its rugged construction, economical price and day-in day-out dependability. The result has been more than 3500 Techno Wings Hammermill installations, in virtually every industry. Our mills can be found in more than 50 countries worldwide.

Gravity discharge hammer mills


Description of Gravity discharge hammer mills

Techno wings gravity discharge hammer mill are durable utility grinders capable of grinding most dry, free-flowing materials. The techno wings bottom discharge hammer mill comprises of a heavy duty mild steel fabricated body (alternatively stainless steel construction can be provided in hammer mill wherever necessary). Hammer mills operate on the principle that most materials will grind or crush upon impact with the hammers or blades. The material is feed into a hammer mill from the top and gravity falls into the grinding chamber. The grinding chamber of hammer mill is lined with serrated wear plates, which protects the body from wear and tear. The materials are contacted by a series of rotating, swing & dynamically balance blades / hammers. The material is ground by repeated contact with these hammers / blades, contact with the serrated wear plates of the grinding chamber, and particle to particle contact. The material remains in the grinding chamber until it is suitably sized to pass through the perforated screen that covers the bottom half of the grinding chamber. Ground materials are discharge by gravity force.

Operating principle of gravity 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 beater / 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.

Typical application of gravity hammer mill

Hammer mills are exclusively meant for the grinding of sugar, salt, bangle grams, maize, pulses, cow dung, glass, oil cake et cetera
