Hammer Mill and Working Principle
The hammer mill, which is used in different areas of the food industry and farms, especially in feed and flour factories, provides the crushing and grinding of granular products. With the help of rotating rotor, the products in the mill are divided into smaller pieces. After the raw materials are crushed, they pass through screens with suitable holes for the required particle size. The raw material separated into particles is collected in a hopper or silo. Basically, the working principle of the hammer mill is simple, but the efficiency of the machine depends on variables such as beaters, screen, rotation speed, filter quality and etc.
History Of Hammer Mill
The history of the hammer mill, one of the most important machines of the feed industry, is actually very old. Unlike the hammer mills used today, these machines were frequently used in the mining and weapon industry in previous centuries. Although the hammer mill has been developing and gaining new features, there are many sources that it has been used for more than a thousand years. Chinese engineer and inventor Zu Chongzhi invented the water-powered hammer mill in 488 AD. During this period, the hammer mills received the necessary power to crush raw materials by means of hammers from strongly flowing rivers. On the same principle working water mills were used in many countries such as England, Austria and Germany in the Middle Ages. Under the leadership of a German scientist named Georgius Agricola, a more advanced water-powered hammer mill has been used frequently for mining operations.
Although there is no exact source about the date on which the hammer mill became modern, it is estimated to be in the early 1800s. After the Industrial Revolution, the use of steam-powered hammer mills also increased. In the 20th century, hammer mills were used frequently by factories in different sectors. Since 1990, hammer mill models with various features and more affordable prices have emerged that are easily accessible by manufacturers. In the last two decades, hammer mills have gradually developed to provide more efficiency and energy savings. Today, hammer mills are used to provide maximum advantages for both food and work safety.
Usage Areas of Hammer Mill
Hammer mills are one of the main machines used in many industries, especially the food industry. Hammer mills that can be used as feed and flour mills are frequently used for crushing products such as corn, oats, barley and rice. Likewise, powder feed can be made from granular raw materials thank to hammer mills, which have an important place in feed production facilities. Hammer mills are also used for processing certain metals and chemicals.
How to Understand a Quality Hammer Mill?
If you are thinking of buying a hammer mill you should pay attention to a few features. First of all; a hammer mill that can be used in the food industry have to be manufactured with food grade material. Hammer mills’ beaters are usually made of steel. Heat treatment allows the hardening of the beater and the shredding and grinding processes to occur with less impact. Another feature you should pay attention is that the hammer mill has a high grinding capacity. Choosing a machine that allows you to grind raw materials with different moisture capacities and sizes will give you a great advantage. It will also be beneficial to place a magnet at the feed inlet of the hammer mill to protect the screens from hit of metal objects.
Quiet operation of a hammer mill is also very important. Too much vibration of the machine will reduce efficiency and cause an uncomfortable working environment. Likewise, it will be possible to diversify the products you can use with your machine with a hammer mill with sieve options that help reduce raw materials to different sizes. With Yemtar hammer mills, with energy saving feature, you will need as less maintenance as possible and you can use your machine in the most efficient way and make your production safely.
