What is a ball mill and how does it function?

Ball Mill is widely used in metal and nonmetal mines, building materials and other industrial sectors of various minerals and rock grinding operation.

Principle: The rotation is through the ball mill motor driven pinion gear shift operation,

the pinion installed on the cylinder rotation gear, and slow down, speed gear are

rotating cylinder operation to work, the material in the feed gradually into the hollow

shaft cover cylinder body, in the cylinder spins, centrifugal force and friction generated,

so that medium (steel balls) and the ore up to a certain height with the cylinder wall

when the weight of a parabola with its fall or drip down , grind the ore is mainly

broken by the impact when the media fall when the abrasive force and motion to

achieve, the cylinder with the movement of ore into the ore to rely on constant

pressure to achieve, the final discharge from the discharge cover of the hollow

shaft. Wet grinding, the ore taken away by water, dry mill, the ore is extracted to the

air outside the tube out.(Zoneding Machine)
Henan Zhongke Engineering Technology Co.,Ltd tell you something about Ball Mill:

The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.

To grind the material continuously that, to feed from one end and to collect the discharge in a cyclone from other end with the help of a fan. The classifier may be of mechanical type or for a very precise & fine separation variable speed motor driven classifier is also available.

Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding. At a certain point, controlled by the mill speed, the load nearest the wall of the cylinder breaks free and it is so quickly followed by other sections in the top curves as to form a cascading, sliding stream containing several layers of balls separated by material of varying thickness.

Why is Taiwan so important for Beijing?

Mainland China has always strived for possesion of Taiwan, and there are many tensions between the two countries. If China eventually does gain possesion of Taiwan, it would be considered a "success" for Beijing in the eyes of the Chinese people and demonstrated the might of Beijing. Taiwan is a US look-out base for China. US and China are of course not allies. Who would want their country to be surroundered by their enemies? And Taiwan becoming independent could harm China's one china policy- Tibet and other regions potentially could become independent.

Why does stainless steel pa 304 have a high ppm of Cr and Ni and is it suitable used for lead free soldering process any other grade of stainless steel more suitable for lead free process?

304 is a food grade of stainless. I am also reasearching this subject at present. My research of online sources- see Johnsons solder ac-600- reveals that a specific aggressive soldering flux is req'd. The type of solder is also impotrant in regards to application type. Each type is a different combination designed for different applications. Some have better bridging strength, or higher/lower melting points, better electrical conduction, and some contain cadmium which poisons food in a cooking application. Perhaps search solder manufacturers for more info.

What is meant by three sigma limits?

Three sigma limits refer to a statistical concept where data points outside three standard deviations from the mean are considered unusual or significant. This range covers about 99.7% of the data in a normal distribution, making it a common measure of variability in quality control and process improvement. Identifying points beyond three sigma limits can indicate potential issues or anomalies that may require further investigation or corrective action.

What is the definition of Large Cement Plants and Mini Cement Plants?

The plant capacity to produce cement will determine whether its a large or mini cement plants.Now that construction activity is at a everlasting speed there is a greater demand for cement which is the main constituent for construction works.So cement plants specially a large one have a daily capacity of production of 10000tons to 15000tons per day of clinker the main constituent of cement which grinded finely with 3%of gypsum will finally produce the Cement. A mini cement plant capacity is some 200 -250 t/h capacity plant .
The definition of plants is multicellular organisms which include grass, trees, mosses, shrubs, and herbs.
