Rock Processing Plant Roller Crusher Machine Sand Making Plant

Slag is produced during the smelting process in several ways.Firstly, slag represents undesired impurities in the metals being smelted, which float to the top during the smelting process.Secondly, metals start to oxidize as they are smelted, and slag forms a protective crust of oxides on the top of the metal being smelted, protecting the liquid metal underneath.When the metal is smelted to satisfaction, the slag is skimmed from the top and disposed of in a slag heap to age.Aging slag is an important part of the process, as it needs to be exposed to the weather and allowed to break down slightly before it can be used.Roll crushers have the advantage of producing an end-product that is has a fine size distribution and they produce little dust or fines during operation.They are widely used for crushing minerals whose abrasive levels are low and in the small scale production of mine.Roll crushers are mostly used during coal mining.The crushers used may either be single roll or double roll.When used in coal mining, the surface of the rolls will have teeth or raised forms (when used for minerald and metal ores, the rolls have a smooth surface).The oretically speaking, the maximum reduction ratio of roll crushers is 4:1.For example, the smallest size that can be recognized by a particle os 2inches is 1/2 an inch.Using this machine, a material is crushed and reduced to a minimum particle size of 10mesh (2mm).The materials are crushed by compression between two rolls rotating about a shaft.The size between the two rools used for compression can be suitably adjusted according to the desired size of the end-product.It is important to note that the largest particle size of the materilas inserted should not be more than four times the dimension of the gap.Sand making plant consists of vibrating feeder, jaw crusher, vertical shaft impact crusher (sand making machine), vibrating screen, sand washing machine, belt conveyor and centrally electric controlling system, etc.The designed capacity is from 50t/h to 500t/h.After many years' research, our company has developed an internationally advanced vertical shaft impact crusher, which can be used together with other machinery as a complete sand making flow.This design racks a leading role in the same industry.As a professional roll crusher manufacturer in china, shanghai gulin machinery company can produce several kinds of crushing machines, including roll crusher, jaw crusher, hammer crusher, cone crusher, and vertical impact crusher, etc.Aside from crushing machine, we also offer mining equipment, cement equipment, rolling mill, and fertilizer equipment, etc.They have passed iso9001:2000 certification and sgs certification and are well received in vietnam, bengal, myanmar, laos, peru, philippines, iran, india and other countries.
