The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Cement rotary kiln is the main equipment of calcining the cement clinker. The characteristics of a rotary kiln are simple structure, convenient and reliable control of the producing process.
In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace.
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%.
