Spiral Classifier for Mineral Processing
In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it … Read more
Rake Classifier
Let me describe a cycle of the Rake Classifier arm to you. The arm, with a series of rakes along its length, drops into the flow of slurry and is pulled upwards. Some of the fine material will flow over, the top of the rake. The rest will be pulled along with the coarser heavier … Read more
Screw Classifiers
To be successful in a obtaining a uniform grind that is necessary to achieve a high percentage of recovery it is necessary to control the degree of fineness that the ore is reduced to. This is done by separating the fine material from the course and regrinding the coarse until it is fine enough for … Read more
Grinding Circuit and Mill Safety
Grinding circuits are made up of large, moving pieces of machinery. When carrying or moving objects in and around this equipment extreme care should be taken. As an example, when operating the crane, never hoist anything directly over the mills. If it is necessary to take long pieces of material, like pipes and lumber … Read more
Ball Mill Circulating Load
The concept and theory to best understand a Ball Mill Circulating Load is shown here as an excerpt from Arthur and Ball mill circulating load PPT Circulating load based on pulp density Circulating load based on screen analysis
Operating and Troubleshooting a Grinding Circuit
In the operation of a grinding circuit you are managing several pieces of equipment as a single unit. If you make a change in the ore in the fine ore bin, that change will be reflected through the entire grinding process and beyond into the rest of the concentration system. The first thing that an … Read more
Hydrocyclone Operation
The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the “OVERFLOW” via a Vortex Finder. The mineral that still requires grinding is named the “UNDERFLOW” via the Apex Finder. These two … Read more
Operating a Grinding Circuit -Understand Your Flowsheet
The next thing that I would like to discuss is the operation of the circuit as a unit. The CIRCUIT is the common name obtained from the path that the ore takes as it progresses through any particular process. In this case grinding. I won’t deal with start-up procedure as it will change from mine … Read more
