Applications Details Jaw crushers are always at the very front of the sample preparation chain, pre-crushing all hard and brittle materials. They are primarily used in laboratories and pilot plants under rough conditions but are also suitable for on-line quality control of raw materials.
The PIPELINE DELUMPER In-line Processor converts a solids-laden stream into a fully suspended homogeneous flow — instantly. It stops settling out, clustering and over pressure. The reduced particles are entrained in the stream, away from the pipe walls. Scale is dislodged from reactors, silos and tanks and is crushed before it can impede the flow.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, 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.
Stowage Factor of bulk cargoes Stowage factor (SF) indicates how many cubic metres (or cubic feet) of space one metric tonne of a particular type of cargo occupies in a hold of a cargo ship.
