How to improve jaw crusher performance and productivity 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. Avoid bridging Continuous bridging in the feeding area of jaw crushers is a common problem. WHAT IS IT? Bridging means stones blocking the flow from entering or moving down in the crushing chamber. It can be caused by just one stone that is larger than the feed opening, or then many average-sized stones of crossing against each other and blocking the crusher’s feed. WHY IT IS A 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. HOW TO PREVENT BRIDGING? Bridging can be avoided by implementing a tight control of the blasting grid to avoid generating oversize material, training the truck loader operator to separate the oversize material at the pit and the primary crushing plant operator visualizing the flow of material to the crusher and controlling the stones’ speed and direction by varying feeder speed and using the hydraulic hammer installed in the area. Apply the proper jaw die profile There are many kinds of rocks, differing in crushability, abrasiveness, flakiness, etc. Choosing the best combination of fixed and movable jaw dies profiles will help to optimize production when crushing difficult material. A Rock of low crushability requires a closer nip angle to keep the capacity as designed. A highly abrasive rock requires thicker and heavier jaw dies that last longer, thus avoiding loss of production due to frequent stops to replace them. Flaky rock requires toothed jaw dies to crush it into more cubical pieces, avoiding stops due to bridging and belt cutting along the crushing circuit. Having the appropriate jaw die profile saves more than 20% of production capacity that would otherwise be a loss. Let’s use the same example scenario as in the first one with the C130 model. 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. 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.  Want more information on Crushing Solutions or a Consultative approach to choosing your next machine? We can help by providing a profitability calculator, production forecast and a full costing run down.
