The grinding ceramic ball mill uses different ball mill ceramic liner types according to production needs to meet different needs.The finess of ceramic ball mills depend on the grinding time.The electro-hydraulic machine is auto-coupled and decompressed to reduce the starting current.Its structure is divided into integral and independent.
There are so many differences between ball mills, rod mills and sag mills.How should we choose in specific applications?.
An example of a four station planetary mill available through the gilson company is shown below.To grind a sample in this device, you should already have reduced the particle size to less than 10 mm, using a mortar and pestle if necessary.Place your material in one of the bowls (shown in the lower right) and then add several balls (shown in a tray at the bottom).Samples can be run wet or dry.A cover is placed on the bowl and then the bowl is mounted in the machine.In the picture below, one bowl has been fastened down and the other has not yet been secured.Once the bowls are mounted and secured, the cover is lowered and the machine can be operated.Each bowl sits on an independent rotatable platform, and the entire assembly of four bowls is also rotated in a direction opposite to the direction of the bowl platform rotation.This action is a lot like the "teacup and saucer" rides commonly found in amusement parks.In planetary action, centrifugal forces alternately add and subtract.The grinding balls roll halfway around the bowls and then are thrown across the bowls, impacting on the opposite walls at high speed.Grinding is further intensified by interaction of the balls and sample.Planetary action gives up to 20 g acceleration and reduces the grinding time to about 2/3 of a simple centrifugal mill (one that simply spins around).Grinding media are available in agate, sintered corundum, tungsten carbide, tempered chrome steel, stainless steel, zirconium oxide, and polyamide plastic.The exact type of bowl and balls that are used depend on the type of material being ground.For example, very hard samples might require tungsten carbide balls in steel bowls.For typical use, agate is a good choice.As with any method of grinding, cross contamination of the sample with the grinding unit material can be a complication.While ball mills save considerable time and effort over hand grinding with a mortar and pestle, this is not without cost.List prices for the simplest jar mills are in the ballpark of $3,000 usd, and 4-station mills like the one shown above can cost $10,000 or more.Grinding bowls with lids can be $1,000 to $2,000 each depending on the size and the material required.Balls can add from $25 to $400 per bowl depending on your material needs.
(4) if the conditions permit, centralize the ball mill in a special ball mill room, and transform the ball mill room into a special sound insulation room, the effect will be better than the sound insulation cover, but must pay attention to solving the ball mill operation monitoring, indoor heat dissipation and maintenance problem.

The production of lead and zinc ore at 7.10 million tonnes in 2009-10 increased by about 6% as compared to that in the previous year.The metal content of lead and zinc in the ore produced in 2009-10 worked out to 129,752 tonnes and 745,969 tonnes, respectively as against 128,732 tonnes and 919,139 tonnes, respectively, in the previous year,ball mill is used widely in lead & zinc ores and concentrates(used ball mills for sale in india).
The ball mill is a horizontal structure.When ball mill works, the rotation of grinding body drives the steel balls inside.The grinding media, steel balls, reach a high point and fall down.The compaction against each other grinds materials into powder.The product is discharged through the discharge grates.
Hongxing is the manufacturer and supplier of ball mills used in cement industry in china.Hongxing has manufactured and supplied ball mills for grinding raw material, ore and cement clinker.Cement ball mill is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).The quill shaft adopts cast steel part and the liner is detachable.The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance.The machine is with stable and reliable working condition.Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
A ball mill is a sort of mining equipment used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It takes a shot at the rule of impact and attrition, size decrease is finished by impact as the balls drop from close to the highest point of the shell.
Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks and artificial sand-making.There are many types of rod mills that customers can choose from, including dry rod mill, limestone rod mill and mineral rod mill.The main feature of the rod grinder lies in that during the ore grinding process, the grinding media and the rocks touch in a linear manner, so that the grinding and crushing is selective.The granularity of the final products is relatively even and the over crushing particles are few.When applied to coarse grinding, the processing capacity of the ore rod mill is higher than that of the ball mill with the same specifications.
Miningball mill feed, pebble crushingaggregatesroad, concrete, asphalt, mining haul roadssecondary or tertiary crushing applications.
The rod mill adopts overflow type and open type discharge, does not use grate type discharge.The diameter of the rod mill discharge end is larger than that of the same size ball mill.When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state.For the ball mill, depending on the specific requirements, you can choose the overflow type and grate type of discharge method.
