Meanwhile, in Hungary, stone grinding was not adequate to grind the hard wheat varieties that grew well there. New ways of milling were explored and the steam roller mill was invented in 1865. During the next two decades, over 300 of these new mills were built in Hungary to support the growing flour milling industry, which became the country ...
The Ball Mill is used for grinding crystalline materials and for mixing dry, or under certain circumstances, moist materials. The drum is available with 5 l volume. The balls are made of stainless steel with a diameter from 30 to 50 mm. The drum is sealed airtight with a lid and is delivered including a frame for the drive unit.
The grinding media balls in the ball mill are used in cement plant to help grind blocky or granular grindable materials produced in the cement manufacturing process, so as to achieve the effect of grinding. Vertical roller mill(VRM) and clinker grinding mill and other cement grinding mill are also very common in cement plant.

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
Officially, hardness testing loads are expressed in Newton (N). However, historically, loads were expressed in kilogram-force (kgf), gram-force (gf), or pond (p). The correlation between kgf, kp, and N is: 1.0 kgf = 1,000 gf = 1.0 kp = 9.81 N. The term micro hardness testing is usually used when indentation loads are below or equal to 1 kgf.
