The compound crusher is used to crush a variety of medium hard ores, such as limestone, clinker,coal and other ores, which can be widely used in mining, metallurgy, refractory, cement, coal,glass, ceramics, electric power and other industries, and is one of the commonly used equipment in the crushing production line and the sand making production line. This series of crusher is a new product based on our company's PEL vertical compound crusher and optimized with domestic and foreign fine crushing technology. Its performance has reached the domestic advanced level. It is mainly for all kinds of ore with compressive strength not exceeding 200MPa and water content less than 15%.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
