Supposing you need to make wood pellets to use for heating, but you have large pieces of wood, which cannot obviously fit into the pellet-making machine. What you need to do is to breakdown these wooden blocks into wooden chips. There are many methods of doing this but the simplest is by use of a machine called a hammer mill. These machines are not only used for breaking down wooden blocks, but may also be used for crushing other materials such as rocks and mineral ores into finer particles. Apart from the pellet making process, these hammer mills are very important pieces of equipment in several industries such as ethanol plants, farm machinery, milling grain and fruit juice production.
Hammer mills are arguably the most efficient grinding machines for most materials. As such, there is a wide range of these machines, varying from size, capacity, power consumption, cost, and purpose. To make the mills user-friendly, they come fitted with automatic controls, which allow anyone to operate them easily, and ensure the safety of the operators and that of others around the area.
The construction of hammer mills consists of a spindle shaft that is mounted on a cast iron body. They also have a grinding chamber, which has numerous revolving beaters, where raw materials are fed for grinding. After grinding, the fine particles are discharged through a series of filter screens located at the bottom of the mill. The speed with which the beaters revolve can be adjusted accordingly, in order to control the quality of the grinding.
Hammer milling machines are very important in most industries since they save time and energy that would otherwise be used in crushing or shredding various ingredients for use in the manufacturing process. The advantages of using a hammer mill include:
- It saves time and energy.
- It is efficient in power consumption
- It requires little or no maintenance
- It is available in an assortment of sizes, capacities and cost
