Myanmar Ore Rod Mill

A rotating drum causes friction and attrition between steel rods and ore particles rod mills are less common than ball mills for grinding minerals the rods used in the mill usually a highcarbon steel can vary in both the length and the diameter used dominion rod mill 95 ft x 14 ft long 500 hp motor

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded for an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore the rod charge must be maintained in good working condition and broken and worn rods must be removed rod

Rod mill introduction the hongxing rod mill manufacturer adopts advanced controllable feeding and discharging technology combined with the actual grinding material with the appropriate grinding body and the traditional surface contact is changed into line contact so that the discharge granularity is more uniform and the output is higher

Ball mill is widely used in mining smeltingroadbuilding material and chemical it is the key equipment for grinding after the crush mill consists of feeding device driving assembly rotating assembly bearing unitdischarging assembly and foundation is a high technological enterprise that integrated research manufacture sales and service

Ball mill also known as ball grinding machine a wellknown ore grinding machine widely used in the mining construction aggregate start the ball mill business since 1985 supply globally service includes design manufacturing installation and free operation training

Notes the rod charging amount shall be limited up to 38 of the mills internal volume capacities listed in the above table are based on tests with ores of wi15kwhmt and 80 of 15mm undersized particles with wet grinding in closed circuit

Jun 11 2019 the rods and ore were loaded into the mill through a sealed bolton front plate for grinding and the front down tilting stand allowed for easy rod removal and clean up with the mix of rods and the mill running over night we got a dry grind of 200 mesh on about 20 kgs of minus ore thats a 86 times reduction

The steel head rod mill sometimes call a bar mill gives the ore dressing engineer a very wide choice in grinding can easily secure a standard steel head rod mill suited to his particular problem the successful operation of any grinding unit is largely dependent on the method of

Energy required which in this case was to grind the ore represented by the samples from a feed size f80 of 152 mm to 80 passing 17 mm and a simple adjustment procedure in case the sag product size needed to be adjusted bond rod and ball mill work indices are readily converted to pinion energy for rod and ball mills but not for sag mills

Bond rod mill grindability the bond rod mill grindability test is performed similarly to the ball mill test the feed sample is stagecrushed to 125mm and the test is run under a 100 circulating load the test can also be closed with various sieve sizes but for agsag mill analyses the standard 14mesh 118mm sieve is typically used
