Sand dryer applies to granular materials in general, especially suitable for drying sand, river sand, quartz sand, silica sand, etc.
Cassiterite is usually a yellowish-brown to brownish-black mineral. In order to make full use of cassiterite, it is necessary to make a series of processes such as crushing, beneficiation and purification.
Stone crushing plant is also called rock crushing plant, which is the professional industrial machine to crush sand and stones. It is mainly composed of vibrating feeder, jaw crusher, impact crusher,
Lignite is a kind of mineral coal with minimum coalification degree. Because it is rich in volatile elements, it is easy to be burnt and generate smoke.
For limenite beneficiation, a combined beneficiation method is often better than a single beneficiation method, which can better improve the ore grade and recovery rate.
Rice husk is the outer shell of rice, which can be used to make soy sauce, wine and power. In daily production, rice husk is basically treated as agricultural waste to be discarded or combustion, which has low utilization rate.
Application Area:Building materials, chemicals, fertilizer, metallurgy, mining, refractory, ceramic, steel, thermal power, coal, etc.
