Cone Crusher Oil System, Dust Seal & Thrust Bearing

The second group of crusher components consists of the Cone Crusher’s oil system, the Cone Crusher’s dust seal and the thrust-bearing. The oil system, like the one used with the primary crusher, is one that requires a large EXTERNAL RESERVOIR. It has the same features that was described earlier in the chapter that dealt with […]
Tramp Steel & Cone Crusher Hydroset

As you can imagine the forces that are put onto the main frame and body of a cone crusher are fairly great. So what happens if something that can’t be crushed, like a steel bolt, gets into the crusher? Instead of damaging itself the crusher has a built in safety device. The tramp steel release. […]
Cone Crusher Distributor Plate

As the ore enters the crusher it lands on top of the cone crusher’s distributor plate and is evenly spread over the entire crushing surface by that gyrating action. We will come back to the crushing action in a few moments but first let’s finish discussing the components of the crusher. The remaining five parts […]
Secondary & Tertiary Crushing Circuits

In this sector on Secondary and Tertiary crushing, we will continue the practice of talking about different equipment, the work it does, and the effects of what I call operating variables. These variables are anything that affect the performance of the equipment. Lets begin with an over view of these two crushing stages. Then describe various […]

Jaw Crusher Safety

The operating skills that are needed to be developed are almost identical to the ones that we just finished discussing with the gyratory. The same operating variables and job perimeters are in effect here as well so I won’t go into them. Before getting into the next chapter there are a few Jaw Crusher Safety […]
Jaw Crusher Components & Parts

Although the jaws do the work, the real heart of the jaw crusher and its components are the toggle plates, the pitman, and the ply wheel. These are the parts and components that generate the crushing action and provide the energy needed to break the ore. Let’s follow the chain of events within a crushing cycle […]
Crusher Circuit Capacity and Feed Quality

The fourth operating variable is the capacity of the crushing circuit. We have talked about the size of the ore, the hardness, and the condition of the equipment, the RPM, and the speed in which the crusher will crush the ore. The sum of these things add up […]
Crusher Concave Liners and Mantle Wear

As the Crusher Concave Liners and Mantle Wear out there is a period when the crusher won’t be as efficient as it could be. This can be a very frustrating period for the operators. Since the throughput drops and operators have to work harder, usually doing the same thing over and over again. Unfortunately to get the […]
Low Sulphidation Epithermal Gold Deposits

Although they are a product of the same igneous system, low sulfidation epithermals gold deposits are very different from high sulfidation. In low sulfidation the main control for Gold deposition, is fluid boiling – caused by a drop in the confining pressures the fluid approaches the surface. This below is an image of a simple […]
