Metallurgical Plant Sampling Techniques
Concentrator Slurry Sampling In milling operations sampling is essential to proper control. This can only be based on the results obtained through sampling the various materials throughout a plant. Sampling of the feed, concentrates, tailings and other products give data indicating the effectiveness of the entire operation. Often these results are desired for comparative purposes for each […]
Portable XRF Analyzer & Price List
See many used XRF Analyzer Models and their prices. Here I list the price of a Portable XRF Analyzer (AKA handheld XRF spectrometer) depends on functionality and Brand. Used models can save you as much as 70% over new ones. REVIEW XRF TECHNICAL SPECIFICATIONS BY BRAND: Olympus/Bruker/Niton/Oxford/Spectro Visit our XRF Discussion Forum Olympus offers a variety of […]

How to Size & Design a Regrind Ball Mill
Regrind Ball Mill F = 210 micrometers. P = 45 micrometers. Wi = 14.0 W = 10 x 14.0/√45 – 10 x 14.0/√210 = 11.21 kwh/s. ton Efficiency Factors: EF1 does not apply. EF2 Many regrind operations are closed circuit, but assume this one is open circuit and 80 percent passing grind will be […]
Pebble Mill Design Calculations – HOW TO
Pebble Mill: Rod Mill Pebble Mill Circuit The calculation for determining grinding power for Pebble milling (secondary autogenous) can be the same as for ball milling from rod mill product size to the desired specified size, neglecting the diameter efficiency factor if less than 1.0. 5.47 x 1.102 x 1.341 x 500 = 4039 […]

Rod Mill Design Calculations
EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of […]
