Mine ownership alternated several times between Wismut and the local hard coal mining company. In the early 1950s, when the coal field belonged to the hard coal mining company, two new main shafts in Dresden-Gittersee were sunk to depths of about 700 m and the mine was renamed 'Willi Agatz', after a leader of the East German communist party.
Both types of mill include liners that protect the cylindrical structure of the mill from wear. Thus the main wear parts in these mills are the balls themselves, and the liners. The balls are simply "consumed" by the wear process and must be re-stocked, whereas the liners must be periodically replaced.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

The Division of Geology and Mineral Resources (DGMR) has mapped five major coal-bearing geologic formations within this sequence of rocks including from youngest to oldest the Harlan, Wise, Norton, Lee, and Pocahontas Formations (Nolde, 1994). The coal beds vary in thickness from less than 1 foot to about 11 feet (Brown and others, 1952).

Aug 06, 2016· Today we will learn about bearing and types of bearings. Bearing is a machine element that have constrained relative motions and used to reduces friction between moving parts of machine to obtain desired motion or we can say that the machine elements which are support the rotating parts of a machine and reduce friction are called bearings.
The main mining areas were around Aachen, the Ruhr and Saar area, along with many smaller areas in other parts of Germany. These areas grew and were shaped by coal mining and coal processing, and this is still visible even after the end of the coal mining. Coal mining reached its peak in the first half of the 20th century.
A line shaft is a power driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century. Prior to the widespread use of electric motors small enough to be connected directly to each piece of machinery, line shafting was used to distribute power from a large central power source to machinery throughout a workshop or an ...
