Jaw crushers have evolved through proven experience in mine and mineral industries. Our main aim is to process hard and abrasive mineral stones with very low power consumption. The Jaw crushers have a high crushing ratio and a uniform product size. They are very easy on maintenance due to its simple yet highly stable structure.


1. Introduction. One of the main challenges of the mining industry is the processing of low-grade ores. This type of ores obliges high processing plant throughput rates, which would result in increased energy consumption and operational costs (Wills, 1992, McGrath et al., 2018).It has been referred that, on average, 44% of the total electricity consumption is …


The crushing and grinding operations are an important part of the processing of mineral resources, and it is also operation with high investment and high energy consumption. In the case of metal mines, equipment investment in crushing operations accounts for 65% to 70% of the total plant value, power consumption is about 50% to 65%, and steel consumption is as …

Producing such a fine crush generally requires multiple crushing stations of up to 4 being but as a minimum of 2 being oversized. The gape determines the maximum size of material that can be accepted. Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape.


Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

From Wikipedia, the free encyclopedia Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. How is a mineral dissociated from an ore?


When looking at overall crushing circuit design, having the correct number of crushing stages also helps minimize fines production. A typical crushing circuit will generate a reduction ration between 5:1 and 7:1 for maximum efficiency. For example, to generate a 10mm particle, you'll want to feed the crusher particles between 50 and 70mm.

the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments. So the objective crushing is to reduce the large lumps in to smaller sizes.


LIBERATION of the mineral is to reduce the size of the particle till – individual particles are rich, the size obtained responds to subsequent concentration process. 76 71. OBJECTIVES.

grinding (Figure 1). Primary crushing is often done close to the mining area, e.g. underground or in the pit. Depending on the ore and process types there can be several crushing steps and different kind of crushers have been developed for different purposes. The size reduction ration is commonly between 5 and 10 in crushing stages, i.e. if the


Screening and grading are to separate materials of suitable particle size during the crushing process, or divide the materials into different particle size levels for selection.
