A Gravity Or Cyclonic Hammer Mill?

Before you can even consider the process with regards to the pellet mill, size reduction needs to be the focus of the pellet plant. The pellet press needs a material that is smaller in diameter than the holes in the pellet die.So say wood pellets are typically 6mm, you need to provide the pellet machine with particles below 6mm. This usually means you will use a 5mm screen in the hammer mill. The process of how the hammer mill works is very simple. You have a perforated screen (5mm holes), there is a collection of flailing hammers that spin at a very high speed, several thousand RPM. As material comes into contact with these hammers due to the speed of impact the material shatters. This process is continued unit the particles are small enough to leave through the 5mm screen holes. There are two main types of hammer mill, there are either based on a gravity system or a cyclonic system. This difference does not relate to the actual process of size reduction but the removal of particles post size reduction. In our small scale pellet plants we use a gravity hammer mill as you can see from the image above. This basically means that the material flows through the machine only by gravity and we then use a screw auger in the base to collect the material and move it onto the pellet mill. The advantages of this system is there is less dust which is better for operators and in keeping dust our of the finished pellets. What is also means is we can use a second small auger to feed in a powered binder such as modified corn starch if necessary in precise quantities. The other version of a hammer mill uses a fan and a cyclone separator to collect the material from the based of the material and deposit it into the pellet press. The problem with this is that cyclones are not 100% efficient at separating material from the air flow. Therefore fine dust will leave the top of the cyclone.

The Hammer Mill Crusher is a type of impact mill or crusher in which materials are reduced in size by hammers revolving rapidly in a vertical plane within a steel casing. Also known as beater mill. A grinding

This Hammer Mill Crusher is using for supporting Pelletizer and this Hammer Mill can reduce the size of raw wood from Diammeter 700 MM into 2-5 MM, so it is the ideal Wood Working Machine for supporting Pelletizer. Therefore, if you want to make Wood Pellets with big raw wood, please try this Hammer Mill to make proper size of Sawdust, then you can make good quality of Pellets.
