After the test, the dry grinding and wet grinding condition, different particle size distribution, surface area, crystal structure, properties of the surface amorphous and thermal properties and grinding time is inversely proportional to the. The results showed, dry grinding can lead to crystal structure of disordered, amorphous and surface activity surface enhanced at the same time the particle size decreases with the progress of ground, wet ground permanently reduced in the planetary ball mill quartz powder grinding limit. Powdered quartz is a kind of nature in weathered silicate mineral powder, the powder has been in Guangdong, Jiangxi and other provinces in China were found. Because it has high purity, has been used in rubber, plastic, composite material as a filler materials and coatings. But in the application of small particle size and high surface chemical activity is sometimes necessary. Therefore, naturally weathered quartz powder dry or dry grinding is thought to be important in the processing stage of. As everyone knows, do not cause the destruction of ground particles and mechanical chemical action，In front of the factors with the diversity of particle size distribution and the characteristics of the change of specific surface area. The latter to a variety of crystal structure form, for example, making the lattice distortion and defects of casting, no shape, group free radical, free surface enhancement, electronic radiation, plasma appearance and so on. These changes increased the surface material dynamic degree and its reactivity. But the natural weathered powdered quartz test, namely about it on dry ground under mechanical chemical action, not recorded. Therefore, this experiment on dry ground under mechanical chemical action result of powder quartz processing and using is very necessary. Powdery quartz specimen in a planetary ball mill is grinding. Particle size distribution, specific surface area characteristics, crystal structure, surface of amorphous and changes, in dry grinding and wet grinding was tested with grinding time is inversely proportional to. From these data, dry grinding device and its powder by mechanical chemical interactions are considered with different ground conditions are linked. A lab for rotary speed of 400RPM per minute ( XPW-100X 4) scale planetary ball mill. From 5 to6 mm diameter of the alumina ball was used to fill the cylinder body of the ball mill40% volume as the ball mill grinding medium. As the land of sample XRD is a graphite monochromator is used together with CuKa radiation powder diffractometer executed. Diffraction angle is from 50DEG to 70 DEG. By experimental condition is as follows:0.01 DEG phase width and fixed time0.01 seconds. DTA ( TAS100) was started at 100 degrees C / minute rate of heating. Infrared absorption spectrum at2mg and 200 mg KBr quartz powder specimen role by infrared spectroscopy instrument obtained. Standard light is in the 400 and4000 / cm. In order to test the dry ground surface amorphous layer group solubility, water sample and alkaline solution was used to do the experiment As a study of natural powdery quartz from Guangdong Province of county .It is a kind of natural weathering of silicate , the grain size is as follows: the average particle size of 10.4 microns diameter and maximum for the particle size of 30 microns. The chemical composition of the sample according to the following ( % ): SiO2 99.48; Fe2O3 0.023; A1203 0.062; CaO 0.062; K20 0.020; Na2O 0.031; TiO2 0.025. The sample after repeated cleaning to remove the clay after being put into a 500 ml volume container in the container with a diameter of 5to 6 mm of alumina ball. 30 g starting material in each at the beginning of the experiment were strictly controlled. Grind time by varying from 6 to30 h. Dry surface sample and wet ground sample are marked as D0, D3, D6, D12...And W 0, W1, W3, W6... ... written in the bottom number in hours said grinding time. Then the land by the particle size analyzer sample analysis. BET, XRD, DTA, IR and solubility test. The limit on dry ground,1.28 microns in wet ground is1 micron. And there is evidence, particle size on the wet ground conditions than when they are dry grind down small, of course, wet grinding grinding grinding grinding limit than the dry limit is lower. Therefore, wet grinding to reduce particle size size is more effective, because the particles in wet grinding than in dry grinding conditions better be dispelled and not easily in the grinding of hold together to form a clique. In this article, powder quartz mechanical chemical action is through the planetary ball mill test. After observation, found the average particle size of D50 or D50planets have been reduced to a minimum and then with the grinding time to increase its began to increase. In the ball mill powder quartz" grinding limit" is the1.28and 1 micron O micron respectively correspond to the dry grinding and wet grinding. Wet grinding can improve grinding crushed quartz efficiency compared with the dry grinding. The planetary ball mill provided by the energy can cause disordered structure, the surface of the amorphous and surface activity of enhanced accompanied by the ground and particle size reduction. Apparently, XRD peak reduction, in the IR region spectral absorption wavelength of the endothermic peak peak degradation, in573 degree C after reducing and dry ground sample solubility in sodium hydroxide solution with the fine grinding and increase. 6
