PERANCANGAN MESIN PEMECAH BATU JENIS HAMMER MILL KAPASITAS 6m^3/HARI

Infrastructure development in this developing countries lately is still very massive, a large amount of gravel resources are needed but people still using conventional methods such as manual methods so some device are needed to boosting the rate of gravel production. In this design, writer developing a stone crushing machine with type Hammer Mill which is a form of centrifugal force come from a flail that rotated on a drum to accelerate the production rate. From the results of designing and calculations, the dimensions of this machine are 0.786m, 0.786m long, and 750rpm rotational spee
