How Stone Crushing Equipment Can Contribute to Mining Efficiency

June 22, 2018

The purpose of this post is to demonstrate the capabilities of stone crushing equipment. In particular, we wish to study the different crusher types and discover how each form factor impacts mining efficiency. Keep in mind, mining complexes can’t carry out their screening duties unless every single featureless stone is neatly broken down. Processed by several lines of stone crushers, the efficiency coefficient is shaped by the following factors.

Gyratory and Jaw Crushing

Initially, the efficiency rating of a primary crushing station is low. The alloy-reinforced jaws break large stones down into manageable chunks. A nearby worker can even hear the operation, which proceeds as a series of explosive cracks. The energetic mechanical motions are plainly releasing losses. Meanwhile, a secondary housing, located further down the line, uses its jaws to smash smaller stones. Further and further away from the primary crushers, the losses are dropping and equipment efficiency is on the rise.

Breaking Down The Numbers

Instead of stone crushing, we’re going to break down the numbers. Think of the flow rate of the stone crushing stages. They should move fast but still efficiently reduce the large rocks so that they can be screened properly. In this engineering formula, tonnage reduction per hour is influenced by a handful of equipment factors. The aperture of the grizzly guards, the lithological characteristics of the rocky stream, the work output-to-energy input ratio, all of these factors are plugged into the equation. Then, as the crushers function as process cascades, the coarse rocks are broken into a fine sand, amongst which lays the non-crushable minerals.

Mining Efficiency: Building a Healthy Profit Margin

The mineral seam has been found. It’s a huge resource, and the mine owners are about to be rich. Except, that profit is being hit by efficiency problems. The primary crushers are overheating. Further down the line, the gyratory crushers are breaking down because the initial cut isn’t properly reduced. If the screening equipment is to process the differently graded particles, the various crushing stations must function like a cascading mechanism. One to the next, primary to secondary, the crushers step-down the tonnage size until only a fine stream remains at the crusher discharge chute.

So how does an equipment supplier assure a broadened efficiency rating, one that’s based on a high-velocity tonnage rate and a multistage stone reduction capability? Well, the primary crushers call in grizzly bars and rock smashing jaws. The jaws are assisted by non-choking plates and the swinging action of a toggle plate. Likewise, gyratory crushers use exceptional mechanisms to assure loss minimization and a healthy end-cycle profit margin.
