Auto Suction Hammer Mills

We offer customers automatic suction hammer mill that comes in capacity ranging from 6 H.P. To 85 H.P. Available under the brand name 'Techno Wings' these automatic machines maintain due to continuity flow through automatic suction through motor. Further, the ampere of motor does not fluctuate, hence increasing the working capacity of machine. The basic principle is straight forward. A hammer mill is essentially a steel drum containing a horizontal rotating shaft or drum on which hammers / blade are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper. The material is impacted by the hammer bars / blade and is thereby shredded and expelled through screens in the drum of a selected size.

Key features of auto suction hammer mill

• Less operating cost due to automatic feeding.
• The size of cyclone body tank is bigger in these hammer mills.
• Automatic operations less production cost Easy to work & collect ground material without air pressure, due to dust collector.
• Through rotary suction machine red chili, cumin, coriander, husk of ground nut, rice bran, seeds of aratictrec (batool) soya bean are automatically sucked.
• Due to availability of beater carbides in automatic machines, it is not necessary to change beater frequently, which also ensures that production is not effected.
• Separate motor for hammer mill, blower, and rotary feeder, thus ampere of motors does not fluctuate, hence increasing the working capacity of machine.

Operating principle of auto suction hammer mill

The materials to be ground into the crushing chamber of auto suction hammer mill from feed hopper by gravity or through an automatic rotary feeder the carbides 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 pulverises the material. The ground materials are continuously sucked by a centrifugal blower through screens placed at the bottom periphery of the crushing chamber and conveyed through a pipe into the cyclone dust collector for bagging. Excess air filtered through an air classifier. Particle size varied using screens with different size holes.

Application of auto suction hammer mill

Hammer mills are exclusively meant for the grinding of turmeric, red chili, cumin, coriander, mango powder, sugar, wheat for ladu, salt, coffee, ayurvedic / homeopathic medicines herbs, roots, leaves, bark, dry fish, cattle and poultry feeds, food colors and so on so forth at large scale basis.

Construction of auto suction hammer mill

Rotary feeder is supplied with gear box. 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. Blower is driven on a separate shaft with the help of a 'v' belts & separate motor.
