The Hammer Mill’s Industrial Advantages

The hammer mill is an essential piece of equipment in the food processing, chemical, and pharmaceutical industries. They are used to crush, shred, grind or pulverize to reduce material to required sizes.


Though they come in different types, the working principle of a hammer mill is just the same. Its fundamental aspects include the following:




  •  Feeding mechanism - this is the process through which the particles enter the crushing chamber of the machine. The mechanism can use either metered or gravity feeding system, depending on the design of the hammer mill machine. When the application calls for product uniformity, the metered feeding system is commonly used since they prevent inconsistencies from possible variables to occur.
  • Control box - this is where the user can turn on or off the machine. Its features depend on the unique design of the milling equipment. This is used to control the motor speed or the feeding system. Some hammer mill machines come with a display panel where processes can be monitored.
  • Hammers or crushing knives - they are the most fundamental tools that grind materials. Their rotation speed can range from 2,500 up to 60,000 rpm. They are usually mounted on the horizontal shafts and rotate clockwise or counter-clockwise. These tools can be attached directly to a motor or driven by a belt. The belts are most used since they can protect the motor from shock and provide accurate speed alignment.
  • Hammer mill screens - typically, the size of the particles to be grinded depends on the variation of screens. They come in more than a dozen types, which are nicely arranged within the crushing chamber.


In several cases, the process of reducing large particles into smaller sizes can result in a fine or coarse finish. When you need a fine finish, the key aspects that your business should consider include a fast rotating rotor speed, small screen size, and large or more crushing hammers. When you need a coarse finish, you can employ the opposite conditions.


Another important consideration in using a hammer mill is its production capacity. The factors that determine the capacity of hammer mills include the materials to be crushed or ground, the feed size, the number of rows of crushing hammers or knives, and the type of the crushing hammers.


To achieve the best results with a hammer mill, your business needs to determine the right motor, crushing hammers or knives and the particle size intended. Being rugged and durable, Classifier Milling System’s hammer mill grinders are preferred by many manufacturing and chemical plants globally. They require minimal maintenance to ensure optimum efficiency and longer service life of component parts. Each of our machines deliver reduced downtime, giving you lower operating costs.

very impressed with the service we received, really went above and beyond
