Vibratory feeder in the production line can transport the material with the shape of massive and particles smoothly to the feeding device in a stable time.
Ceramic sand kiln is one kind of calcining kilns which is a rotary cylinder machine used for calcining all types of materials.
Linear vibrating screen is widely used for screening any dry materials whose diameter is 0.074-15mm and the biggest feeding granularity is less than 20mm.
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.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
The purpose ofintermediatecrushing is to produce several coarse-grade products – for example, road base aggregates – or to prepare material for final recrushing. Generally the goal ofsecondary, tertiary, and quaternary crushing is to obtain the best possible size reduction at the lowest cost.

Mining-Mining- Undergroundmining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surfaceminingbecomes prohibitive, and underground techniques must be considered. Counting against undergroundminingare the costs, which, for each ton of material mined, are much higher underground than on the ...
