Cone crusher is the machine that is made up of two cones. Cone crusher is suitable to crush medium-hardness or harder ores and rocks.
Hammer crusher, also called hammer mill crusher, is one of the major tertiary crushers for brittle materials in metallurgy, building material, chemical engineering and hydropower like limestone or coal, etc.
Single cylinder rotary cooler is suitable for cooling clinker out from rotary kiln. Rotary drum cooler can rapidly cool clinker out from rotary kiln from 1000-1300 ℃ to 200 ℃).
Sponge iron briquetting machine is also called sponge iron briquette machine. It can be classified into vertical type and horizontal type.
VSI sand maker, also called VSI crusher, is the major machine for sand making plant. During the crushing process of sand making machine, raw materials hit each other and not hit any metal parts.
The high pressure briquetting machine or the high pressure ball press machine is used to press many kinds of materials such as gypsum, coal powder, mineral powder, scale cinder, slag, fine iron powder and aluminum ash etc.
Dust collector is a kind of dedusting devices with wide application range. It includes the bag type dust collector, impulse bag precipitator, electrostatic precipitator, wet scrubber and electric-bag filter, etc.
Shaking table is a kind of ore separating machines, mainly for separating ores like tin, tungsten, gold, silver, lead, zinc, tantalum, niobium, iron, manganese, titanium and coal, etc.
