Jaw crushers are designed for primary crushing of hard rocks without rubbing and with minimum dust. Jaw crushers may be utilized for materials such as coal, granite, basalt, river gravel, bauxite, marble, slag, hard rock, limestone, iron ore, magazine ore, etc., within a pressure resistance strength of 200 MPa.
Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in …
Roll Crushers are built to handle primary, secondary and tertiary stage crushing of friable materials such as coal, salt, clay, bauxite and more. They are used for the crushing or medium-hard rock as well as for sticky and soft materials, such as lignite and mineral coal, clay, marl, limestone and similar raw materials as well as for overburden ...

Double Roll Crushers. Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds.
Used in a wide variety of applications, Double Roll Crushers can process ROM coal, limestone, gypsum, trona, shale, bauxite, oil shale, clean coal, coke, salt, quicklime, burnt lime, glass, kaolin, brick, shale, and wet, sticky feed materials. In Double Roll Crushers, the material is crushed by a combination of compression, shear and
crushers. Open circuit and closed-circuit crushing circuits are operated, as well as multi-step crushing routes which are possibly used more often to maximise tonnage throughput. Crushing initially reduces the bauxite to a size that the mill can handle, and then the mill delivers a product size suitable for the refinery feed.
