Crushing & Screening Plant
Methods used in Crushing & Screening Plants on ore range from a simple combination of a grizzly and one crusher to an elaborate arrangement in series of grizzly, jaw crusher, screens, and rolls or cone crushers. Crushing is done underground at a few large mines. In general, the jaw crusher is the most suitable primary machine, yet […]
Sampling Conveyor Belt for Crusher Circuit Survey
Let’s review the steps to collect a sample of coarse rocks such as primary Crusher product. The procedure requires that Process Equipment be shut down and so it is important to organize the work to minimize lost time. First the particular conveyor where the sample is to be collected is identified, next, one to two […]
Circulating Load in a Crushing Circuit
Equipment Sizing: Crusher or Grinding Mill
UNTIL THE THIRD THEORY OF COMMINUTION of “Work Index” method of determining crushing and grinding mill size was introduced, there was no way of accurately figuring the most applicable, most economical size of crushing and grinding mill. Naturally, with little or no factual operating data correlated in useful form, it was easy enough, even for […]
Ore, Rock & Aggregate Screening (Complete Guide)
A-Z Guide to Screening Ore, Rock & Aggregate A simple definition of a “screen” is a machine with surface(s) used to classify materials by size. Screening is defined as “The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface”. Knowledge of screening comes […]
See-saw Crusher
The See-Saw Crusher is made of a very heavy stone or steel ‘see-saw’ crushers are rolled over the material which is to be crushed with the aid of a lever arm. The material is placed on a flat stone or steel surface and the product is similar to that from a roller crusher.
Screening 101
Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of […]
Small Jaw Crushers
We offer two types of forced feed and yet small jaw crushers: The Type “H” has cast steel or alloy iron frame, steel bumper with over-size roller eccentric bearings, bronze side bearings and manganese steel jaw and cheek plates. The Type “J” is made in two styles, one with bronze bearings and the other with anti-friction […]
Vibrating Screens in Mineral Processing: Types and Advantages
Vibrating Screen SPECIFICATIONS The driven sheave and balance wheels are on the center line of the shaft. The shaft supports no other load and is subjected to no flexing or bending, and rotates freely on its central axis. The driven sheave can be mounted on either end of the shaft depending on whether a right […]
Laboratory Magnetic Separators
Some type of Magnetic Separator is always advisable and should be a standard piece of equipment in every mill. When one (Suspended Type) Magnet is located just ahead of the primary jaw crusher, and another is placed before the intermediate crusher, all danger of damage to the crushers from tramp iron is eliminated. The tramp iron […]
