The Samap manual grain mill employs grinding stones made of all natural stone NaxosBasalt embedded in stabilized Magnesite. These grinding stones will not need to be sharpened even after years of continuous use. The adjustable feeding speed feature allows the grinding capacity to be set according to the grain to be milled.

If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter 8 foot diameter mill, then the same will be true for a 5.0 meter 15 foot diameter mill.

In case study 2, following the change of the bearings of the grinding rolls, the plant team was looking for a way to reduce the risk of bearing failure. During mill operation roller surfaces wear down, which results in a higher dynamic load, peaks which exceed the nominal torque and, in general, an instable mill operation and lower performance.

Premature failure of a cylindrical roller bearing of a gear box input shaft from a hot strip mill has been investigated. The pins of the cylindrical rollers of the bearing broke from the welded joints at their ends on the cage ring. Investigations were carried out on the failed roller pin and the welded joint.
