Crushing Plant Flowsheet & Design-Layout 911 Metallurgist
Crushing Plant Flowsheet & Design-Layout. In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2-in. size, but they work much more efficiently if their feed is ½ in. or less. Before the advent of the Symons cone Ore blending is an essential part of daily work in the concentrator. Qualified ore dressing products can make the ore dressing more smoothly. The existing ore blending modeling usually only considers the quality of ore blending products and ignores the effect of ore blending on ore dressing.

Self-tuning control of an ore crusher ScienceDirect
An industrial application is described where a self-tuning regulator is used for control of an ore crusher. There are difficult control problems associated with this process due to significant variations in operating conditions and long time delays in the system. The design of a self-tuning regulator for the crusher is discussed in detail.The paper shows the preparation of the numerical models necessary for the simulation mapping of industrial-scale crushers of problematic material, such as copper ore with complex lithology. The crushers investigated in this work are located in the KGHM Polska Miedz S.A. copper ore processing plant.
