The mill power draw, throughput and product size distribution are used to compute a specific energy input and the macpherson autogenous work index awi. although the importance to achieve steady-state in a grinding test is widely accepted bond tests, the macpherson test remains the only small-scale agsag mill test that offers this option.The bond rod mill grindability test is a widely used tool to estimate the response of ores to rod milling. however, the mass of ore required to conduct the test, which can typically vary from about 8 to as much as 20 kg, may represent a challenge when sample availability is critical. the present work proposes an alternative procedure, which is based on the size-mass balance model with a specific account for the 2.1 media mills. media mills are the most widely used machines for fine grinding of powders. these machines contain individual loose grinding elements—the grinding media—which can consist of balls, rods, pebbles, beads, etc.Prominer provides ball mill rod mill grinding system which is widely used in various types of ores beneficiation, electricity, cement and chemical industries. it can carry out dry or wet pulverizing and can meet demand for sustainable large-scale production.Apr 09, 2015 different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. because of the name, verb milling is also been used as a synonym for grinding. milling, sometimes also known as fine grinding, pulverizing or comminution, is the process of reducing materials to a powder of fine or very fine size.China high quality alloy steel grinding rod used in rod mill for metal mines, find details about china grinding rod, steel rods from high quality alloy steel grinding rod used in rod mill for metal mines - shandong dahe grinding media co., ltd.Grinding mills are commonly used in mill for rock phosphate grinding - crusher unit phosphate rock crushing equipment for sale. zenith mining ore crushing equipments have good market zenith powder grinding mills has gotten good reputation from Aug 03, 2012 rod consumption varies widely with the characteristics of the mill feed, mill speed, rod length, and product size it is normally in the range 0.1-1.0 kg of steel per tonne of ore for wet grinding, being less for dry grinding. rod mills are normally run at between 50 and 65 of the critical speed, so that the rods cascade rather than cataract Wet grid ball mill . capacity 0.5-500tph feed size ≤25 mm. grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. the size of ore shall not exceed 65mm and the best feed size is under 6mm. the effect in this job is better
