The hammer mill is an essential piece of equipment in many key industries, facilitating production in materials, food processing, chemical and pharmaceutical industries among many others. They are used to crush, shred, grind or pulverize materials to required sizes for production, construction, assembly or distribution.
Hammer mills have fundamental aspects which contribute to any commercial enterprise including substantial benefits in precision, speed and durability.
These are some of the key components in a hammer mill:
Control box - Features depend on the unique design of the milling equipment, which can be adapted to the specific application at hand. 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 - Rotation speed can range from 2,500 up to 60,000 rpm. Mounted on the horizontal shafts and rotate clockwise or counter-clockwise. Can be attached directly to a motor or driven by a belt. Belts are most commonly used as they prevent more shock and provide can be brought into more accurate speed alignment.
Hammer mill screens - The size of the particles to be ground depends on the variation of screens. They come in more than a dozen types, which are arranged within the crushing chamber according to the needs of the enterprise; fine grind processing can produce powder grade materials commonly found in diverse products from coffee to castable refractory materials.
Alternate screens can produce coarse finishes more common in construction and industrial applications. A range of qualities can be produced with the right rotor speed, screen size, and appropriate crushing hammers.
A hammer mill also has a production capacity. The customizable capacity of hammer mills include the materials feed size, the number of rows of crushing hammers or knives, and the type of the crushing hammers employed – these can determine volume, speed and grade.
Hammer Mills require minimal maintenance to ensure optimum efficiency and provide longer service life when serviced with the corresponding component parts.
