We bring forth a highly advanced ball mill, specifically engineered for both wet as well as dry cement grinding applications.Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.It is highly acknowledged for effective and quick grinding in several industries such as limestone, cement, coal, iron ore, chrome ore and many others.The major highlight in the mill is its fully automatic function with plc control and instrumentation.
Ftm machinery, as the ceramic ball mill supplier, produced 60t, 40t, 10t, and 0.1-1t ceramic ball mill according to different productivities.
The bond ball mill work index is a measure of the resistance of the material to grinding in a ball mill.It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions.It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
With a view to developing a sound basis for the design and scale-up of ball mills, a large amount of data available in the literature were analyzed for variation of the two key mill performance parameters: power specific values of the absolute breakage rate of the coarsest size fraction, s*, and absolute rate of production of fines, f*, with some of the important operating and design variables such as the mill speed, ball load, particle load, ball diameter and mill diameter.In general, values of both the mill performance parameters were found to vary significantly with the mill operating conditions.The nature and relative magnitude of variation for the two parameters also differed significantly.Moreover, the effect of any particular variable on the s* and f* values was found to be significantly different for different sets of operating conditions.It has been emphasized that, as the purpose of grinding is to produce fine particles, the mill design and scale-up work should be based mainly on the f* parameters.Moreover, it is not correct to regard the s* values to be independent of the mill design and operating variables as a general rule, especially for a fine analysis of the performance of the grinding systems.
2.Edge transmission ball mill: the motor drives the gear on the edge of the barrel through the reducer to drive the barrel.
As a part of direct contact with the material, grinding media is an important factor to improve the ball mill grinding efficiency.The efficiency of the ball mill can be improved mainly from two aspects: the proportion of different sized grinding media and timely media refilling.
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.
As we know, ball mill and grinding mill are mainly as the equipment for making powder.Generally, a grinding mill or ball mill is used in all powder production lines that grinds large pieces of ore into fines for the next production process.For example, phosphate powder is needed in the production of phosphate products.A grinding mill or ball mill is used to grind the phosphate ore into powder.
Ball mill is widely used for milling various kinds of ores or rocks in metal and non-metal mining and building material industry.The main bearing of the ball mill with the shell diameter 900-2100mm is spherical liner bearing; for the shell diameter 2700mm, the main bearing is completely closed self-aligning 120bearing with strong alloy of high lead and low tin with low hardness, underneath laid with cooling copper piping full of water the bearing is of static pressure structure with high and low pressure united oil lubricating system.
12.5 ft x 20 ft hardinge ball mill, this ball mill is complete with 1,000 hp ge synchronous motor, 200 rpm, 4,000 volts, 115 amp arm, amp field 66, exc volts 250, 3 phase, 60 cycle.
Ball mill host , which include cylinder system ,which lined with wear-resistant lining product , a fill cylinder preserve bearing rotation , and generate elements that include.Motors, rolling gears ,belt pulley , cone belt and the like.Within the component with the blade ,which ordinarily is not just a leading element ,in the feed facet with the mouth components have within the feed screw which may be known as inside the helical blade , inside the discharge facet with the mouth components with the within the feed screw which also can be known as a spiral inside the spiral blade.
In china's new nissan more than 5,000 tons of dry cement production line raw material grinding and slag grinding line has an annual output of more than 500,000 tons all the henan red star lm series of vertical roller mill suitable for grinding of cement raw material processing of coal and cement clinker, especially in the grinding of cement and slag, steel slag and other materials, the materials stay in the grinding area than the traditional, vertical mill, henan hongxing li grinding product particle shape and size distribution close to the ball mill product, and thus help to improve the cement (fine slag powder, high fine slag powder) hydration performance, increase strength, cement enterprises with large vertical mill in coal preparation, slag grinding, gypsum grinding calcined and powder grinding non-metallic mineral has good development prospects.As the state strictly controls the cement production can be opened to the big screen, some cement companies to speed up the merger and reorganization, to lose ground at the same time, the cement into the sand and gravel aggregate, new materials and non-metallic mineral has been sounded to expand to new profit space horn, or even extending to the financial industry, real estate, we can see that the cement companies to explore the way new industries has become a trend.Mining equipment to become the "hero" of the cement companies, cement companies the great leap forward.
