  • GENERAL CONCLUSIONS OF THE PREVIOUS ANALYSIS
    • Static or stationary Cutters do not take the actual complete granulometric profile. 
    • This leads to differences up to 15% in the actual mass distribution taken from the stream.
    • Non Standard designed cross cutters lose a significant portion of the sample.
    • This leads to differences of up to 12% (or more) in calculated mass balance vs. real fine in concentrates. 
    • The only equipment that guarantees a representative sample, is a cross cutter and/or rotary cutter, well designed. 
    • For a sampling system to work properly, it should also include a good design of: cross and rotatory equipment, pipelines, ducts, slurry boxes, chutes, handling of rejects, among others.
    • It is important that the client has proper equipment maintenance procedure.
