What is the baryte and what is the price of a specialized ultrafine grinding machine

2018-01-06

Baryte or barite (BaSO4) is a mineral consisting of barium sulfate. The baryte group consists of baryte, celestine, anglesite and anhydrite. Baryte is generally white or colorless, and is the main source of barium. Baryte and celestine form a solid solution (Ba,Sr)SO4. 77% of baryte worldwide is used as a weighting agent for drilling fluids in oil and gas exploration to suppress high formation pressures and prevent blowouts. As a well is drilled, the bit passes through various formations, each with different characteristics. The deeper the hole, the more baryte is needed as a percentage of the total mud mix. An additional benefit of baryte is that it is non-magnetic and thus does not interfere with magnetic measurements taken in the borehole, either during logging-while-drilling or in separate drill hole logging. Baryte used for drilling petroleum wells can be black, blue, brown or gray depending on the ore body. The baryte is finely ground so that at least 97% of the material, by weight, can pass through a 200-mesh (75-μm) screen, and no more than 30%, by weight, can be less than 6 μm diameter. The ground baryte also must be dense enough so that its specific gravity is 4.2 or greater, soft enough to not damage the bearings of a tricone drill bit, chemically inert, and containing no more than 250 milligrams per kilogram of soluble alkaline salts. In August 2010 API (American Petroleum Institute) published specifications to modify the 4.2 drilling grade standards for baryte to include 4.1 SG materials.


Other uses are in added-value applications which include filler in paint and plastics, sound reduction in engine compartments, coat of automobile finishes for smoothness and corrosion resistance, friction products for automobiles and trucks, radiation-shielding cement, glass ceramics and medical applications (for example, a barium meal before a contrast CAT scan). Baryte is supplied in a variety of forms and the price depends on the amount of processing; filler applications commanding higher prices following intense physical processing by grinding and micronising, and there are further premiums for whiteness and brightness and color. It is also used to produce other barium chemicals, notably barium carbonate which is used for the manufacture of LED glass for television and computer screens ( historically in cathode ray tubes); and for dielectrics. Historically baryte was used for the production of barium hydroxide for sugar refining, and as a white pigment for textiles, paper, and paint. Although baryte contains a "heavy" metal (barium), it is not a toxic chemical because of its extreme insolubility.It is also sometimes used as gemstone.


Baryte superfine grinding machine with special rolling, milling, grinding and other mechanical impact performance, has high applicability and practicability for a variety of material with hardness below level 7, humidity less than 6%, as the new development ultrafine grinding equipment has withstood the test in the market practice and user authentication for long term, be economical and practical mainstream equipment of energy saving, is an ideal equipment for processing, 325-2500 mesh powder. Main mill equipped with built-in classifying mechanism, classification wheel is unique structure with good classification effect, good particle size of the product, no large particles pollution. The product quality is stable, grinding wheel, grinding ring are casted with special wear-resistant steel, small abrasion, long service life, can greatly reduce replacement frequency, keep convenient maintenance. It is ideal equipment for producing fine powder of non-metallic ore at present.


Fujian Fengli baryte ultrafine grinding mill: MT ultrafine grinding mill
