Rock Breaker BPM is higher than recommended, what could be the most posible reason?
Answers
Answer:
Designed to break large rocks, rock breakers or generally called as hydraulic hammers, as an attachment to backhoe loaders, excavators etc., are generally used in the mining industry where oversized rocks are too large or hard to be reduced in size by a crusher. A hydraulic hammer to break rocks and a boom (arm) are two major components of the rock breaker. There are two major types of rock breakers i.e., mobile and stationary, typically placed on a pedestal or slew frame.
Generally, rock breaks are used to perform various tasks. These include...
1. Rock mining without blasting: Rock breakers are used for primary rock mining to increase productivity and save time. The rock breakers can in fact reduce the load on the primary crusher, thereby, increasing the latter’s output. Rock mining without blasting is also environment-friendly as the blasting emissions are eliminated. Also, this method boosts safety at the site as there are no flying rocks in the air.
2. Secondary reduction: In cases when the blasted rock is too big to be handled by loading equipment or the crusher, the importance of secondary reduction comes into play. Even with the most advance blasting techniques, it is inevitable that there will be oversize boulders and these need to be broken as economically as possible. It is in such cases that rock breakers come handy than the crusher.
3. Demolition: Rock breakers are very much suited for the demolition tasks. They are commonly used to break down concrete structures.
