These devices are suitable for breaking and crushing mountain and river rocks whose hardness and abrasion are balanced.

In the two-turn type, due to the ability to adjust the distance between the hammer and the anvil, it is possible to control the size and grain size of the output, and due to high production and also easy replacement of parts and accessories are very efficient. Also, low depreciation of parts is an important advantage of this device (used in mines with non-silica materials)

Sand makers (MS800) or rabbits due to their simplicity as well as uniform production and abundance of spare parts and simplicity of replacement parts as well as high fracture rate of output materials are favored by sand producers and contractors in mines that are of the so-called type. Are used.
