Everyone wants to get the most out of their equipment, and jaw crusher operators are no exception. There are several factors that affect crusher performance and thus the whole circuit. Here are a few things that can help you avoid production losses.
Continuous bridging in the feeding area of jaw crushers is a common problem.
Bridging can cause a significant loss of production that oftentimes goes unnoticed. It is relevant to keep an eye on bridging in the feeding area of a primary crusher as it can take several minutes to resolve the issue (big rock being removed, fragmented or directed to the chamber). If it occurs say ten times in a day, it quickly leads to one hour of lost production.
If that happens, for instance, in one of our crusher models including stone crusher, cone crusher, etc., C130 with 352 short ton per hour (stph) working capacity and assuming a USD 12 /short ton, the daily loss can easily add up to four thousand dollars.
Monitor the condition of jaws
Besides being an important item for the dryer machine’s performance, the jaw crusher’s jaws are responsible for front frame and swing jaw protection. Wear generally causes loss in production due to increased crushing angle, loss of tooth profile, reduction of the CSS to compensate the possible lamellar effect, etc. That is why it needs to be monitored throughout the crusher’s lifecycle.
As excessive wear can cause a 10–20% reduction in production, it is important to find the optimal time for the jaw turn or change in terms of cost and benefit. Again, with the same scenario with C130, we would have approximately a 70 stph reduction in production, in other words, a decrease of USD 4000 to 8000 in revenue for one day.
Is an Impact Crusher right for my business?
To summarise, an Impact Crusher has more versatility than a Jaw and Cone Crusher since it can simultaneously perform primary and secondary duties.
We're big fans of Impact Crushers as wastes recyling because they produce excellent results for our customers and have thus far; been unbeatable as a total machine solution.
