Auto Suction Hammer Mills
Designed to reduce energy and labor costs, the auto
suction Hammer Mill’s rotary feeder allows for
unattended "drop and go" operation. After receiving
spices like red chili, coriander, Ajowan, Anardana,
Aniseed, Caraway, Celery Seed, Cumin, Black Cumin,
Dill, Fennel, Fenugreek, Mustard, Poppy Seed, Basil
Leaves, Tejpat (Bay Leaf), Curry Leaves, Hyssop,
Marjoram, Thyme Leaves, Mint, Parsley, Sage, Lesser
Cardamom, Greater Cardamom, Juniper, Kokam,
Mace, Star Anise, Tamarind, Vanilla, Black Pepper,
Long Pepper, etc.. Through a large throat and feed
opening, the Batch Feeder automatically unscrambles
and transfers material to the in feed conveyor of a
hammer mill.
Techno Agencies offers our valued customers automatic suction Hammer Mill that comes in
capacity ranging from 5 horsepower to 50 horsepower. 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 / blades 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 / blades and is thereby
shredded and expelled through screens in the drum of a selected size.
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 (Both options are supplied with the
auto suction hammer mills) the carbide's 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 to be continuously sucked by
a centrifugal blower which is driven by separate electric motor 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.

motors does not fluctuate, hence increasing the working capacity of machine.
Less operating cost due to automatic feeding.
The size of cyclone is bigger than economic or standard hammer mills
Automatic operations less production cost
Easy to work & collect ground material without air pressure, due to specialized design
of hammer mill.
Through rotary suction machine red chilli, cummins, coriander, husk of ground nut, rice
bran, seeds of aratic trec (Batool), rice straw, wheat straw, oat straw, soya bean is
automatically sucked.
Due to availability of carbide beater blades in automatic feed pulverizer machines, it is
not necessary to change beater frequently, which also ensures that production is not
effected.

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.
