It is the fraction passing through -3 mm size sieve. Basically for control of quality and productivity of sinter plant, the crushing index (-3 mm) should be maximum and at the same time fine fraction (-0.5 mm or below) should be minimum. for detai...
May 02, 2016· In an integrated steel plant coal and coke preparation units demand application of high performance hammers in coal crushing units to maintain high coal crushing index and heavy duty screen decks for maximizing yield of sized coke (25-80 mm fraction). These components work under severe wear due to the combined effects of fatigue and impact loadings.
the finer sizes. If a coal contains a high percentage of middlings material, SGS can perform the crushing studies required to determine if additional yield can be obtained by liberating coal from the middlings through crushing. SGS coal float/sink analysis can be done on samples ranging in size from bulk washability samples (over 1 ton) to core
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
hammer heads and the crushing mill cover, that resulted into the crushing index > 80% for <3.0mm size coal. Uniform coal size improved the bulk density of coal in ovens and finally assists in improving the productivity quality of and coke in the coke ovens.

In a continuous mining process, in-pit crushing and sizing stations play an important role in efficiently reducing material size, while reducing or eliminating the need for traditional truck haulage. We provide decades of experience and expertise in designing and installing the most effective and economical crushing and sizing systems.
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Triple crushing action makes our one-way Hammermills ideally suited for primary and secondary reduction of limestone, chemicals, minerals, coal and many ores. LEARN MORE.
Abstract. Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most expedient.There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.
Jun 05, 2013· Abrasion index is an index that shows the abrasive properties (abrasion) of coal on the part of the equipment used to grind the coal before being used as fuel in certain combustion systems. The higher the index the abrasive coal the higher the maintenance costs of the coal grinding equipment.

Crushing reduces the overall topsize of the ROM coal so that it can be more easily handled and processed within the CPP. Crushing requirements are an important part of CPP design and there are a number of different types. Screening. Screens in screening plant are used to group process particles into ranges by size. These size ranges are also called grades.

The Kuz–Ram model is generally used for prediction of the fragmentation size after blasting. The Kuz–Ram model is an empirical fragmentation model based on the Kuznetsov (1973) and Rosin and Rammler (1933) equations modified by Cunningham, 1983, Cunningham, 1987 which derives the uniformity index in the Rosin–Rammler equation from blasting parameters.
