Introduction to CF420C Electric Hammer Mill
This CF420 hammer mill is newly developed machine which is endowed
with many advantages compared to other kind of crushers such as
simple construction, convenient operation, high efficiency, saving
power consumption, and safe condition. It is suitable to crush raw
materials with small size such as tree branches, bamboo, wood scrap, old cardboard and newspaper,
straw, crop stalks and corn cobs and so on. After crushing, raw materials are uniform and with
proper moisture content to meet further processing. With capacity
200-700kg/h, it is can surely meet the production requirement in
the farms, middle sized feeding factory or family.
Key Features of CF420C Electric Hammer Mill
1. With capacity 200kg—700kg/h, this hammer mill can satisfy a
large production demand on a daily basis.
2. The ability to change screen size, and the option of a variable
speed frequency drive control, enable processing a variety of
materials using the same hammer mill.
3. Both coarse and fine grinding can be realized through adjusting
the gap between hammers and screen
4. The core part —the hammer flake is scientifically designed to
have two concussion parts, thus when one part is worn out, you can
turn over to use the other part.
5. The angle of the screen can be 180° which allows for high
throughput at lower power consumption.
6. Equipped with air blower, the crushed material can be directly
collected and transported to next machine for further processing.
7. The rotor of hammer mill operates at 3,500 RPM to produce high
hammer tip speed, thus the finished powder can be uniform with a
Wood Hammer Mill Cutter & Sieve
A main factor in determining finished particle size is the speed of
the hammer mill. When the rotor spins, the hammers flail out and
impact the material with great severity causing it to break down.
As a result, the higher the rotor speed, the greater the number of
hammer mill blows, and thus a finer end product.
Typical Applications of Electric Hammer Mill
★ Wood Pellet production
★ Feed Pellet production
★ Biomass Briquette production
How Hammer Mill Affects Pellets Quality
Hammer mill can be used to reduce the particle size of the raw
material for pellets production. And the size of particle, which is
dictated by the size of screen used, has a huge impact on the
quality of pellet produced and the productivity of the pellet mill.
Particle size, along with moisture content, is one of the most
significant factors affecting overall pellet quality. Finer
particle sizes generally correspond with greater pellet strength
and durability as larger particles serve as fissure points. Several
researchers observed that optimal pellet quality is achieved with a
mixture of particle sizes due to increased inter-particle bonding
and the elimination of inter-particle spaces. Material grinding is
the most common form of particle size reduction for biomass
feedstock before entering the pelleting process. The survey shows
that hammer mill screen sizes of either 3.2 mm or 3.2 to 4.0 mm
produced the highest quality pellets.
