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.
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 ℃).
High pressure grinding mill has high-pressure springs inside, which can improve the grinding powder to 1.2 times higher. If roller ring is worn out, we can adjust the length of springs to keep the grinding pressure.
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.
Charcoal Briquette Machine can press materials like quicklime powder, dolomite dust, bauxite, nonferrous metal powder, oxide iron powder and iron sheet.
The coal ash dryer made by our company, as the Chinese leading raw coal drying machine supplier, is specialized in drying the coal ash and then makes new use of it.
