In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

A diplexer is a passive device that combines two inputs into a common output. The signals on inputs 1 and 2 occupy different frequency bands. Consequently, the signals on inputs 1 and 2 can coexist on the output without interfering with each other. It is also known as a cross band combiner. A duplexer is a passive device that allows bi ...

The Screw Press is built for dewatering of pulp suspensions from inlet consistencies of 3-12% to outlet consistencies up to 30% and even higher. Excellent washing efficiencies in the sense of removing COD and ionic trash can be achieved, thus the machine is found in pulp and recycled fiber applications.

reject orifices, and thus, they are prone to plugging (Franko, 1984). Hence, lower consistencies or higher reject rates are required with smaller cones to avoid plugging (Franko, 1984). Since smaller cleaners have a much lower capacity, many cones must be used to achieve the same throughput of just a few larger cones (Franko, 1984).
