• Electronic control of crusher discharge opening and feed rate With adjustment of a crusher s discharge opening as the production continues through an on line coarse size analysis of the crushed product digital image analyses Dance A 2001 • More attention is being paid to the impact on crushing circuit design caused by variations
The selection of the stacked crusher configuration and open circuit crushing thereby reduces the overall footprint of the crushing circuit During the selection process it was noted that due to the hardness of the ore the Abon Sizer is at risk of unplanned stoppages due to breakage of the sizer teeth FLS selected an upgraded four segment
A primary crusher reduces large particles into smaller sizes for further crushing by the secondary crusher Examples of crushers include jaw crusher gyratory crusher and roll The energy consumption for crushing an ore is a function of its hardness feed sizes and product sizes The standard measure of energy demand is Bond work index The
A 1D iLDR H radar sensor under a primary crusher measures the level of a 200 meter long ore pass in an iron ore mine in Norway The system shows the continuous changes in the level allowing the customer to control the crushing and conveying

Primary crushing brings run of mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below Dry crushing includes work on ore as mined which may be somewhat moist when delivered It is succeeded by comminution in water arbitrarily called grinding
The right one for a primary crushing application depends on the material to be crushed the feed size the desired product size and the capacity required Primary crushers reduce large run of mine material such as rocks and ore lumps into smaller sizes for further processing downstream whether that be transport to additional crushers or
The double roller crusher should strengthen the iron removal work of feeding ore Non crushing objects bits etc falling into the pair of rollers will damage the crusher resulting in a parking accident Therefore an iron removal device should be installed before the crusher The viscous material is easy to block the crushing space
Jaw Crusher The jaw crusher is used in primary crushing and is therefore usually installed near the mine Crushing in this type of equipment occurs by compression and friction promoted by metal plates one mobile and one fixed jaws The mobile jaw moves and compresses the fragments against the fixed jaw crushing them
The two primary types of crushers are the primary crusher and the secondary crusher The primary crusher is used to reduce the size of large rocks and stones while the secondary crusher further breaks them down into smaller pieces In this article we will discuss the primary crusher and secondary crusher their definitions functions and
