Jaw Crushers are predominately used in the first stage of any crushing application as they can deal with larger sizes of feed material which reduces the costs for the user. Some applications will require a finer product and to process fine sizes additional crushers such as secondary and tertiary (impactors and cones) will be required. When a number of crushers and screens come together, and the material is fed directly from one to another this term is often referred to as a ‘Crushing Train’ which can be configurated in a number of different ways in an effort to generate the required specifications.
It is very important to first assess the feed material itself to make sure you assemble the train correctly and after this look at the fractions you want to achieve throughout the train as a final product. For example, if a feed material is bulky but also quite high in fines rather than beginning with a Jaw it may be beneficial to implement an Anaconda Scalping screen beforehand. The scalping screen will cut out the fines from entering the jaw and help with the efficiency of the operation by preventing a build up in the chamber. This will reduce blockages and eliminate unnecessary wear increasing the life expectancy of your consumables.
