Hammer mill is one of the most widely used grinding mills and also among the oldest. A hammer mill consists of a series of hammers that are hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact.
The materials that have to be milled are cut by these rectangular pieces of hardened steel that rotate at a very high speed inside the chamber. The hammer mills move at a high angular velocity that causes brittle fracture of the feed material.
1. Producing Intermediate Grades of Powder – Hammer mills have the capability to produce intermediate powder and that too for specific applications in the pharmaceutical industry. The powder that is processed using a hammer mill does not have a nominal diameter.
The most wonderful use of this equipment is that it can produce intermediate powder from nearly any material except for sticky substances or materials. Sticky material cannot be processed into a powder because it can choke the screen.
Hammer mill is handy in the pharmaceutical industry, cosmetic, chemical, and food processing.
2. Grinds Legumes and other Dry Products – Grinding is one of the most widely used manufacturing processes in the pharmaceutical, food processing, and cosmetic industry. These include grinding soya, beans, groundnuts, etc.
Hammer mills are used in food processing industries to grind coffee and soya for making beverages. Hammer mills are used in the cosmetic industry where a number of nuts are grounded to make body lotions and creams.
3. Reduces Material Size – It is important to reduce the size of the products like drugs in order to pack them. For example, capsule-filling machines are used to fill powders, pellets, or tablets. The materials with a larger diameter than the standard capsule types need to be reduced to reasonable sizes using a hammer mill. Hammer mills are very beneficial to resize any solids, dry materials, fibrous materials, etc.
4. Improves Formulation or Dissolution – Pharmaceutical, cosmetic, and food processing industries use hammer bills because these industries require mixing products require a large surface area. This is only possible when the size of the particles is reduced.
Small particles make sure that there is an even distribution of particles in the final formulation. A hammer milling machine ensures consistency in particle distribution and produces a higher-quality mixture.
This is why hammer mills are used in the pharmaceutical industry to give every capsule or tablet the right dose quantity.
5. Mixes Solid and Fibrous Materials After Grinding or Milling – The hammer mill reduces the average size of materials and also mixes them at the same time. This is the reason why we get the final product with smaller particles whose ingredients are evenly distributed. This reduces the laborious process of mixing two different powders after grinding.
6. Reduces Active Ingredients of Substances – One of the most important advantages of using hammer mills is that it reduces the active ingredient which is a very important procedure in the pharmaceutical industry. With the help of grinding and milling the substances become much more useful to the end users.
A hammer mill is an effective piece of equipment that grinds mills and mixes various ingredients in order to form a useful end product. It is a cost-effective way that produces a variety of products mixtures, and wet or dry granulations. It is important that you choose high-quality equipment from a reputable manufacturer only. Another useful piece of equipment is a wood pallet crusher that is used to crush and recycle wood wastes.
