Cement Mill is one of the important cement making equipment and key equipment for grinding crushed materials, and plays a vital role in the cement manufacturing process.
Jaw crusher machine, also named jaw crusher for short, is the earliest crusher.
Roller crusher is used for coarse crushing or tertiary crushing. Smooth roll crusher is widely used for industries of ore separating, chemical engineering, cement, refractory material, grinding material and building material, etc.
Spiral classifier, as one of the important machines for ore separating, consists of transmission, spiral, groove, elevator, bearing bush and ore discharging valve.
The multi-cylinder hydraulic cone crusher is a special equipment for hard rock crushing.
The Single-Cylinder Cone Crusher is widely used for medium, fine and superfine crushing operation of mine, aggregate, metal ores, limestone, granite, basalt, river gravel, construction waste, steel slag, cement raw material, ceramic raw materials.
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.
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.
The treatment effectively converted coal to benzene-soluble products with an optimum yield of 57 wt, somewhat less than that obtained in a Znbutyl iodide system. There was no correlation between the rank of coal used and the benzene solubility. Reactions of model compounds were also carried out under similar conditions.

Sep 22, 2012018332This review focuses on ligninolytic fungi, soil bacteria, plants and root exudates in the degradation and solubilisation of low grade and waste coal and the interaction between these mutualistic biocatalysts. Coal represents a considerable portion of the total global fossil fuel reserve and continued demand for, and supply of this resource generates vast quantities of spoil and low grade waste.
