QUARRYING, CRUSHING & SCREENING

Sick and tired of frequent or heavy breaker repair bills? – talk to us…

Whether you are downsizing rock too large to go through the crusher (secondary breaking) or breaking out virgin rock (primary breaking); it’s time to ‘get it right’ for a sustainable operation. There are 4 elementary factors that can affect your hydraulic breaker sustainability:

Compatibility
1. Mount Machinery is acutely knowledgeable about the use of breakers in quarrying & crushing applications with specifications and information about various breaker sizes to help gauge what model is best. Too big a breaker for your machine could result in unsafe working conditions, less production and cause excessive wear. Too small a breaker inflicts excessive stress on the attachment causing structural/mechanical failure resulting in sudden unviable repair costs!
Condition of the hydraulic breaker.
1. A hydraulic breaker is high maintenance and requires regular servicing to keep within the wear limits and avoid a heavy repair bill. Running beyond wear limits can cause major component failure. Regular breaker maintenance is necessary for sustainability, yet it is largely overlooked in the quarrying industry. It not only extends the life of the breaker, but also can keep minor inconveniences from turning into expensive problems sometimes deeming the breaker viably beyond repair.
2. Special purpose grease to keep the tool bushing area adequately lubricated is absolutely necessary to preserve maximum life of the wear parts. The lack of grease can contribute to the snapping of the tool. Some breakers have automatic lube systems to provide a feed of grease to the breaker, but those systems still need a daily inspection to ensure they are still working and there is adequate grease in their vessels. Shiny marks on the tool are a good indication the breaker is not properly lubricated. A good lubrication KPI; you should see an unbroken band of grease around the bush contact area of the tool.
Commissioning of the excavator’s auxiliary circuit for the given attachment.
1. A very important but often neglected part of the process. It’s important that you know the oil flow and pressure parameters of the breaker and make sure the excavator is set up correctly. Never assume the excavator’s computer’s readings are accurate; they rarely are! Always use a calibrated inline flow and pressure meter complete with loading valve. Mount Machinery’s experience in this area is second to none. A hydraulic flow and pressure check is regarded as mandatory at Mount Machinery when pairing a breaker to a hydraulic system to keep within the parameters of the attachment. If the excavator cannot provide enough flow at the right pressure, the breaker won’t perform with maximum output, which lowers productivity and can occasionally cause excessive heat build-up within the excavator. Additionally, a breaker receiving too much flow or pressure can severely damage the breaker sometimes beyond repair! Mount Machinery will conduct flow tests on your machine for optimum performance.
How the hydraulic breaker is operated.
1. Operator training is so crucial to your secondary breaking operation being a success story. Where possible select joystick button control for the breaker as the operator’s thumb will most likely be faster at reacting than the operator’s foot. The operator must develop the art of minimising blank firing to reduce stress on the tool retaining system. Some blank firing is inevitable but anticipating when the rock is about to break goes a long way to keeping blank firing to a minimum. Do not be rough whilst manipulating rocks into position.
