The Roller crusher can be classified into double roller crusher and four roller crusher according to the roller quantity. The Roller Crusher bears the features of stable operation, easy maintenance, low cost, output size adjustable. The Roller Crusher can be used in the processing of fragile materials in cement, metallurgy, chemical, power generation, coal industries.

These roll crushers are available with Gundlach's breakthrough 3-D crushing technology that includes intermeshing continuous tooth roll design and positive roll timing that delivers the industry's best dimensional product control, fewer fines and elimination of over-size material. Gundlach's roll crushers deliver higher quality cubical product, minimal fines and consistently repeatable performance for sizing coal, coke, glass, fertilizer, potash, salts, lime, limestone, soft ores, friable materials and industrial minerals.

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 sizebetween 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.

As a professional technology and center-driven enterprise, KMEC over the years has been committed to high-end development and progress of the mineral processing equipments such as roll crusher machine,other beneficiation equipments, transportation machine. Through the continuous introduction and absorption of R & D and innovation, to form a set of development, design, manufacture, installation, service as one of the strong team of professionals.

This series of roll crusher machine consist of roll wheel, supporting bearing, tightening and adjustment device, actuating device. The discharge product particle can be adjusted by the two roll wheels. The drive mechanism is by two electric motors, belt drive sheave drag roller rotation in accordance with the relative direction of movement. When crushing material, the material from the feed inlet is rolled by the roll wheels until crushed. The crushed product is discharged from the chassis of the roll crusher machine.
