The Styles that You Need to Know About Hammer Mills


If you are tasked to have a certain material made into smaller for a particular purpose, what would you do? Well, this might sound simple for you. In most cases, it is. However there is different number of considerations that you need to note in order for you to finish the work in the most economical as well as efficient way. This is where the use of a hammer mill comes in.

What are Hammer Mills?

Hammer mills are one of the types of machineries among a larger category of size reduction tools or equipments. The category also includes jaw crushers, shredders, roll mills, ram fed grinders and ball mills. If you take a look at it a bit closer even with hammer mills, there are different types of styles to choose from. Among the other style to choose from include the following:

–  The material is fed in the grinding chamber.

–  Contact with interior mill components and moving hammers in order to reduce the material’s size.

–  The material remains in the grinding chamber of the hammer mill until it can now pass through the grate or screen which has certain size openings.

Comparison of the five different styles of hammer mills

–  Gravity discharge hammer mills. The industrial hammer mills are considered to be the simplest and most recognizable function of the hammer mill. A rectangular steel chamber keeps the shaft to which the swinging hammers are attached to. When the shaft rotates at a very high speed the hammers will flail out impact on the material. Aside from the hammers, size reduction occurs whenever there is a particle contact and through contact with the breaker plate which is situated inside the grinding chamber. Since they are simple, the industrial hammer can be easily adaptable to various sizes as well as mill designs. It is important to know that replaceable steel liner plates will protect the interior of the mill from any wear and tear caused by grinding different abrasive materials. The ideal application for this is with coal, glass, dry chemicals, coke, porcelain, metals, resin, ceramics, brass and aggregates.

–  Pneumatic discharge hammer mill. The grinding mechanism in this group is very similar to the gravity discharge in the hammer mills. However, the pneumatic mills usually make use of a thinner hammer and the interior wall to the grinding chamber features which are ribbed liner plate. This particular plate has a washboard effect on the material and usually works in unison with the hammers and has a particle impact in order to reduce the material effectively. The biggest difference is the use of air assistance of the material in order to evacuate material coming from the mill. Whether they are attached to the main mill shaft, or have a separate optional component in a very high production model, the fan will pull the material through the mill and then convey it to storage. It is important to know that specially designed hammers are ideal for shredding and tearing.
