Hammer Grinder Mill
More
exceptional particle size can be achieved in as we compared to the
roller mill. With proper filtration, the hammer grinder mill
allows for more efficient use of malt grains by increasing surface
area. It will require fewer grains to make the same amount of beer
when using a hammer mill.
The
hammer mill power consumption per pound generally higher than roller
mill, but highly efficient on Circ-U-Flow model hammer mill due to
300-degree screen and large rotor diameter resulting in high tip
speed.
According
to the shape of the screener, hammer
grinder mill
can be classified into a half-screen hammer mill, full-screen hammer
mill, and the screen less hammer mill. According to the production
capacity and size, it can be classified into the small hammer mill
and large hammer mill.
Small
hammer mill
Small
hammer mill is also known as half-screen hammer mill because their
screen cloth is a semicircle covering the lower part of the rotor.
The toothed plate is installed in the upper body. Raw materials are
to be fed along the tangent line of the crushing chamber.
Small
hammer mill is a general type. It adapts to different working
conditions. It features small size, low cost and smooth operation.
Small hammer mills are often applied in farm, small feed mill, small
pellet production line, and wood processing plant.
Large
hammer mill
Large
hammer mill is also known as drop-shaped hammer mill. The electric
motors and rotor are welded on the same steel plate base. A pin
coupling directly connects them. With a dynamic balance experiment,
the rotor can be rotated in both of the directions. The feed hopper
is at the top of the hammer mill. You can equip it with a rotary
feeder. The hammers are to be arranged symmetrically. The operation
door is fitted with an interlock device to ensure it is closed during
running.
Roller
Grinder Mill
The
traditional method of dates back to the wind and water power reduces
the particles using a compression force.
The
roller grinder mill power consumption as per pound is generally
lower, but throughout the hour also lower.
There
are no grates or screens used to regulate particle size. Instead of,
particle size and consistency are purely based on the miller's skill
in setting the roller mill effectively.
Post
grinding is impractical because ultimate particle sizes are more
irregular and bigger, requiring more attention and care to achieve
consistent and accurate grind.
Available
capacity of grain is a significant consideration because it can take
larger or multiple roller mills to achieve the same position as a
hammer mill.
Pneumatic
systems are not easily integrated for use with a roller mill.
When
roll chills become worn, replacing or corrugating the old chills is
more expensive and time-consuming.
Types
of Roller Grinder Mills
Two-roller
mills: -
Two roller mills are the most straightforward variety, in which the
material is crushed between the two rollers before it continues to
its final destination. The operator can adjust the spacing between
these two rollers. Thinner spacing often leads to that material being
crushed into smaller pieces.
Four-roller
mills Four-roller mills have two sets of rollers. When you are using
a four-roller mill to mill grain, the grain first goes through
rollers with a rather wide gap, which separates the seed from the
husk without much damage to the husk, but leaves large grits. Flour
is sieved out of the cracked grain, and then the coarse grist and
husks are sent through the second set of rollers, which further crush
the grist without damaging the crusts. Similarly, there are
three-roller mills, in which one of the rollers is used twice.
Five-
and six-roller
mills Six-roller mills have three sets of rollers. When using this
type of mill on grain, the first set of rollers crush the whole
kernel, and its output is divided three ways: Flour immediately is
sent out the mill, grits without a husk proceed to the last roller,
and husk, possibly still containing parts of the seed, go to the
second set of rollers. From the second roller, flour is directly
output, as are husks and any possible seed still in them, and the
husk-free grits are channeled into the last roller. Five-roller mills
are six-roller mills in which one of the rollers performs double
duty.
