primary crusher — the first crusher in a crushing system into which material is fed. succeeding crushers in the system are referred to as secondary or tertiary crushers. product — output from the crusher. reduction ratio — the ratio of the top size of input material to the top size of crusher discharge.

crusher tools e.g. jaw liners are subject to numerous pressure and impact stresses. several other factors affect the wear lifetime of crusher wear parts as listed in below diagram . wear occurs in all crushers , however wear costs can be controlled by selecting the correct crusher type for the abrasive content of the material to be crushed.
wear occurs in all crushers but costs can be controlled by selecting the correct crusher type for the abrasive content of the material to be crushed. the figure below demonstrates how a relatively small increase in abrasive content can result in wear costs increasing. exact wear cost is a function of feed
these impact crushers are capable of producing a high ratio of size reduction in one stage of crushing. however, due to the high velocities of the hammer, the wear rate is very high. impact hammers are, therefore, typically used to crush softer ores such as coal, limestone, and cement plant feed.
types of primary crushers jaw crusher – jaw crushers are used for extremely hard and abrasive materials, with reduction ratios typically as low as 6:1. however, jaw crushers are very durable, have low maintenance requirements, and are effective with almost any type of friable material. they represent a medium investment cost and, generally

a sectional view of the single-toggle type of jaw crusher is shown below. in one respect, the working principle and application of this machine is similar to all type of rock crushers, the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point.the motion is, however, a more complex one than the dodge motion, being the
jaw crushers are used as primary crushers, or the first step in the process of reducing rock. they crush primarily by using compression. the rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
product introduction. jxsc jaw type rock crusher is usually used as a primary crusher and secondary crusher to reduce the size of medium-hard materials to smaller physical size. jaw rock crushers are capable of working with the mobile crushing station, underground crushing because of its related small volume. capacity: 1-1120tph.
the jc series jaw crusher is a new type of jaw crusher with optimized and developed design on structure, material selection, manufacture process and assembly, which is based on absorbing the international advanced technology and applying company's decades design concept and technology of jaw crusher.

a) primary crusher – the raw material from mines is processed first in primary crushers. the input of these crushers is relatively wider and the output products are coarser in size. example - jaw crusher, gyratory crusher, impact crushers, etc. b) secondary crusher- the crushed rocks from primary crusher are sent to these secondary
the crushing process most cement plants these days extract limestone by blasting. this produces many oversize boulders which often contain a lot of clay and sand. the crusher therefore has to handle feed containing fairly large blocks as well as some sticky materials. the proven and reliable flsmidth ev hammer impact crusher is a cost-
