With allexternal parts made of steel or ductile iron with suitable seals for abrasive dust environment. These partswill include hardware, module carrier plate, detent pocket plate, gear coupling and safety element modules.Release torque must be adjustable with provisions to make the adjustment tamperproof.

29. Grinding Machines Grinding Machines are also regarded as machine tools. A distinguishing feature of grinding machines is the rotating abrasive tool. Grinding machine is employed to obtain high accuracy along with very high class of surface finish on the workpiece. However, advent of new generation of grinding wheels and grinding machines,

mills using slide shoe bearings. Since this time, the design has been perfected based on the experience of more than 180 units operating all over the world in various industries. Today Polysius grinding mills are exclusively built as shell-supported units. Ball mill in iron ore bene-fication plant. Ball mill with COMBIFLEX drive for lead zinc .

mill and drive involved. In modern grinding, ball mills and SAG mills are two types of mill commonly found. Grinding mills Ball mills Ball mills vary in their details and size but the basic design consists of a horizontal hollow cylinder, with an abrasion-resistant interior, that rotates about its central axis.

different operations like turning, threading, tapper grinding, end drilling etc. The plant has the capacity to do most of operation except taper grinding. Presently the plant has to outsource the shaft to outside plant for the taper grinding. presently the plant have a grinding machine of G 17-22U, which means it is a universal grinding machine that can machine a job up to 220mm diameter shaft .
