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 […]
Jaw Crusher Liner Plate Design & Profile Shapes
Straight Jaw Plates: A shows a diagram of a standard type of Blake crusher with regular or straight jaw plates. This type of plate has been the standard from the time of its inception, emulating, in this respect, the straight concaves in the gyratory machine. And it will be noted that the theoretical action in this straight-plate […]
Rock Crushing Process in Mining
Let’s follow a rock through a crushing cycle to see what variables will have to be controlled. First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher “breaks it and the fine material produced will drop through the gap between […]
Gyratory Crusher Operation
Crusher are used to reduce the ore in size, the purpose and the responsibility of the crusher operator is to operate that crusher in such a manner as to ensure that every possible ton is processed in the shortest period of time possible. This is accomplished by knowing and understanding all of the Gyratory Crusher Operating […]
Crusher Lubrication System Operation & Maintenance
For easy of Operation & Maintenance, all Rock Crusher Lubrication System include their own monitoring devices, SIGHT GLASSES or VIEW PORTS in the reservoir for oil level, FLOW METERS in the oil lines and/ or VISUAL ACCESS to the discharge point of the oil circuit. This is to allow the operator to gauge the oil […]
Gyratory Crusher Lubrication
The lubrication of Gyratory crushers may be one of the special problems that the Jaw crusher isn’t as readily exposed to. This crusher, because it may be loaded from two sides, often is used in an open pit situation where large ore carriers are dumping directly into the crusher. This means that the machinery is […]
Gyratory Crusher Components
The Gyratory Crusher is made up of six main components, Base, Main frame and concave liners, Drive assembly, Mantle, Spider arm assembly, Oil system. It is this eccentric bushing and bearing that gives the crusher its crushing action. To understand how it works it might help to learn the dictionary meaning of the word eccentric […]
