(3) Regardless of Crusher Size, Material Prep is Key
No matter if you operate a small rock crusher, or a massive aggregate system you will plug your cruhser. The only thing that changes, is the size of the piece that gets stuck. While it is true that bigger rock crushers take bigger pieces this typically doesn't necessarly translate into doubling or tripling the ideal feed size.
There is a difference between the inlet opening of a crusher, the resulting theoretical maximum feed size, and the ideal feed size. The biggest problem is when 2 large rocks come together and bridge up causing a blockage at the inlet. Without material prep it is one big gamble until this happens. The ideal feed size reflects the restraints of your small rock crusher and the mix of materials in your shovel.
Preparing and downsizing the material to the ideal feed size for your small rock crusher is critical to achieve a high production and low operating costs.
"Your small rock crusher is the most likely your most expensive piece of equipment and you want to run it as efficiently as possible and as short as possible".
(4) The Excavator Reach Matters to be Effective
While the size shovel defines the overall feeding pace the reach can affect consistencey. When it comes to rock crushing feeding slow and steady wins the race. Consistency can be achieved through material prep and access to enough material in the close vecinity of the crusher. Typically, the excavator is placed on top of a flat pile and feeds material into the crusher. RUBBLE MASTER small rock crushers can track & crush simultaneously so that you can bring the crusher closer to the pile as you keep feeding the material.
The overall positioning affects also operator safety. With impact crushers you want to place the machine off to the side so that rickocheting stones don't damage your excavator cab.
