The mobile jaw crushers are described as powerful and highly efficient machines which are used for crushing different materials that are needed for further use. Designed to meet the toughest crushing applications, these machines provide reliability, powerful performance, and superior results.
However, dealing with these machines involve some responsibilities, such as safe operation. This simple guide is for all those who are responsible for the operation of the mobile jaw crushers, including operators, managers and supervisory staff.
Different types of layouts
The jaw crushers are normally fed from loading shovels, backhoe excavators or other machinery. In a standard crushing procedure, they are fed directly with the material to be crushed which is then discharged to a stockpile. If the machine is going to be fed directly by an excavator or a loading shovel, certain factors need to be considered, such as:
The causes for crusher blockages can be divided in two main headings: stalling and bridging.
– Stalling can be caused by:
– Bridging can be caused by:
In order to avoid some unwanted accidents or machine failures, make sure to avoid using oversized materials or tramp metal. These materials can easily block the jaw crushers.
What to do if a jaw crusher becomes blocked?
Another major cause for accidents is inadequate guarding. A safe procedure should involve regular machine checks at specified intervals, particularly after cleaning and maintenance work.
In order to minimize the transport risks on your work site, a risk assessment should address:
