Introduce Of Nepheline powder mill equipment;Nepheline micro powder mill:

Firist ,talk about the industrial use of  nepheline.Nepheline, also called nephelite, is a feldspathoid: a silica- undersaturated aluminosilicate that occurs in intrusiveand volcanicrocks with low silica, and in their associated pegmatites. It is often found in micaschistand gneiss.Nepheline mainly used for glass and ceramics industry, or as raw material of the refined aluminum.Crushed Nepheline powder is important raw materials of glass and ceramics industry, or as raw material of the refined aluminum. Before processing Nepheline powderfor glass and ceramics industry, you need firstly Nephelinestone to be 265mesh~ 2500mesh. Clirik offers Nepheline powder mill equipment;Nepheline micro powder mill and high pressure grinding mill to grind Nepheline stone. And you can choose open circuit or closed circuit powder grinding system according to your real situation.

Nepheline powder mill equipment;Nepheline micro powder mill is for super-fine grinding materials with hardness less than 6 in Moh‘s scale and humidity less than 6 percent such as kaolin, limestone, basalt, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds. The granularity (or final size) of the finished products can be freely adjusted between 325-3000meshes (0.045-0.0057mm), and the capacity (ton/hour) ranges from 0.4T/H to 7.5T/H.


Nepheline crystals are rare and belong to the hexagonal system, usually having the form of a short, six-sided prism terminated by the basal plane. It is found in compact, granular aggregates, and can be white, yellow, gray, green, or even reddish. The hardness is 5.5 - 6, and the specific gravity 2.56 - 2.66. It is often translucent with a greasy luster.The low index of refraction and the feeble double refraction in nepheline are nearly the same as in quartz; but since in nepheline the sign of the double refraction is negative, while in quartz it is positive, the two minerals are readily distinguished under the microscope. An important determinative character of nepheline is the ease with which it is decomposed by hydrochloric acid, with separation of gelatinous silica (which may be readily stained by coloring matters) and cubes of salt. For this reason, a clear crystal of nepheline becomes cloudy when immersed in acid.


The mineral is one especially liable to alteration, and in the laboratory various substitution products of nepheline have been prepared. In nature it is frequently altered to zeolites(especially natrolite), sodalite, kaolin, or compact muscovite. Gieseckite and liebenerite are pseudomorphs.Two varieties of nepheline are distinguished, differing in their external appearance and in their mode of occurrence, being analogous in these respects to sanidineand common orthoclaserespectively. Glassy nepheline has the form of small, colorless, transparent crystals and grains with a vitreous luster. It is characteristic of the later volcanic rocks rich in alkalis, such as phonolite, nepheline-basalt, leucite basalt, etc., and also of certain dike-rocks, such as tinguaite. The best crystals occur with mica, sanidine, garnet, etc., in the crystal-lined cavities of the ejected blocks of Monte Somma, Vesuvius. The other variety, known as elaeolite, occurs as large, rough crystals, or more often as irregular masses, which have a greasy luster and are opaque, or at most translucent, with a reddish, greenish, brownish or grey color. It forms an essential constituent of certain alkaline plutonicrocks of the nepheline syeniteseries, which are typically developed in southern Norway.


Features of Nepheline powder mill equipment;Nepheline micro powder mill:

l、 High efficiency
Under the same finished final size and the same motor power, the capacity of Nepheline powder mill equipment;Nepheline micro powder mill is twice as much as jet mill, mixing grinder and ball mill.
2、Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
3、High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
4、 High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.
5、Environment-friendly
The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
