BALL MILL
A ball mill is a type of grinder or mill used to mill the materials into fine powder. This ball mills are especially useful for grinding hard materials.Stainless steel balls are mostly used as balls or grinding material in the ball mills. Steel has the ability to pulverize almost any material. This ball mills are generally used within a laboratory.
HISTORY
Devices for shaking materials along with hard balls might be old, but it was not until the industrial revolution and the invention of steam power that a machine could be built. It is reported to have been used for grinding flint for pottery in 1870.This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method termed mechanical alloying could successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that could not be made by more conventional powder metallurgy methods.
TYPES
There are four types of ball mills as follows- Pebble ball mill
- Vibrating ball mill
- Drum ball mills
- Jet-mills
- Bead-mills
- Horizontal rotary ball mills
MESIN BALL MILL (Artikel Bahasa Indonesia)
Mesin ball mill adalah mesin yang digunakan untuk menghaluskan, melumat atau menghancurkan sutau material menjadi partikel-partikel yang lebih kecil bahkan bubuk. Mesin ball mill yang berbentuk tabung dengan 2 bagian tempat menyimpan material dengan bentuk dan posisi horizontal ini terdiri dari silinder berrongga yang berputar pada porosnya. Sumbu poros biasa disebut shell yang berdiri secara horizontal. Sementara itu, media penggiling terbuat dari baja, stanless steel, atau karet. Permukaan bagian dalam dari shell silinder biasanya dilapisi dengan material yang tidak mudah terkikis seperti bijih mangan dan karet.
Fungsi mesin Ball Mill
Mesin ini biasanya digunakan dalam proses pembuatan cat, kembang api, porselen, bahan kimia, batu bara, semen, pigmen, keramik, felspar untuk tembikar, dan serbuk laser untuk mesin cetak 3D.
