A remotely controlled rock breaker is by far the quickest way to deal with blockages and get the material flow running smoothly again. A rock breaker also allows operators to proactively address potentially problematic oversized or awkwardly shaped boulders before they even reach the primary crushing equipment.
The primary crushing stage is a vital part of the aggregate production process. It is here where maintaining a smooth flow of materials helps to keep the rest of the production process on track. Breakdowns or other stoppages can be extremely costly in terms of both time and money, and have a knock-on effect on the later stages of the process like secondary and fine crushing. Blockages caused by single oversized rocks or coarse or uneven materials becoming jammed are the most frequent cause of stoppages.
Dealing with a blockage involves far more than just removing the problematic rocks and then carrying on; equipment may have to be locked and powered down, and personnel may have to take time out to perform visual inspections – put simply, the entire production process can grind to a halt. To put this into perspective, in a plant processing 500 tons of material per hour, a single period of downtime a day lasting between five and 10 minutes each time can translate into annual revenue losses of as much as €150,000, based on an end-product price of €7 per ton.
With a rock breaker installed in the primary crushing station, blockages and build-ups caused by oversized rocks getting stuck or coarse materials becoming jammed together can be resolved quickly, accurately, and safely. Importantly, the primary crushing process can continue with no break in production. A rock breaker also improves efficiency further along in the process because when the material flow from the primary station remains consistent, the following crushing stages produce better quality aggregates with a higher throughput.
Metso rock breaker solutions are complete functional packages for rock breaking in the primary crushing stage of aggregate production, with every component engineered to meet the tough requirements of this demanding application area. They are optimized to work with Nordberg© C Series jaw crushers to maximize the productivity of the whole primary crushing station.
We recently launched a campaign to promote the Metso Rock Breaker. To find out how it can support the safety and productivity of your operation, visit the rock breaker campaign page on our website.
