Grinding complexes
Description
Open joint-stock company "NPO Center" was established in 1981.[br][/br][br][/br]The company constantly improves and expands its the range of products and now offers grinding complexes for sale.[br][/br][br][/br]Grinding complexes are a modularized system of optionally assembled integrated units which provide high performance, easy operation and servicing, low energy consumption and small occupied space.[br][/br][br][/br]Grinding complexes make it possible to obtain up to 15 t/h of several narrow fractions of the final product in the required particle size range (0,02..0,5 mm).[br][/br][br][/br]Customized production schemes make it possible to improve essentially the economic performances of grinding and quality factors of the obtained material. The size of the final product can be regulated during the operation without the equipment shutdown.[br][/br][br][/br]The challenge grinding complexes face is fine and ultra fine dry grinding as well as disintegration of different ore and non-metallic materials which vary in strength, hardness and abrasiveness.[br][/br][br][/br]Grinding complexes are successively applied in manufacture of mineral powder, cement, micropowder of microcalcite, etc.[br][/br][br][/br]The centrifugal-impact milling method which is realized in "NPO Center" grinding complexes makes it possible to obtain material showing quality factors which are unattainable with the help of other types of milling. [br][/br][br][/br]The crushed product exhibits a high specific surface area and physicochemical activity of the particles. It has the ordered narrow grain size composition.[br][/br][br][/br]The reduction of energy intensity and the absence of over-ground classes are available by the iteration (uninterrupted) operation cycle of complex, i.e.: "grinding – separation – continuous withdrawal of finished product from the process of grinding". Compared to other milling methods, the energy cost saving runs between 12 and 56%[br][/br] [br][/br]Technical specification and principle of operation of grinding complexes can be found at [url]http://www.npo-center.com/en/products/55/170/[/url]

Technology Benefits
The material produced by "NPO Center" mills is distinguished by a narrow granulometric composition (low content of both coarse and fine fractions).[br][/br][br][/br]The particles are homogeneous and isometric in form and they have a well-developed surface. This facilitates the obtaining of durable and quality products and reduces material and energy costs.[br][/br][br][/br]Consistency in grinding properties: product quality does not depend on the state and wear rate of quick-wear elements and equipment.[br][/br][br][/br]- Narrow specified granulometric composition within all possible milling size range (from -0,02 to -0,5 mm).[br][/br]- Possibility to obtain simultaneously several fractions of finished product.[br][/br]- Obtaining of products having isometric form and increased activity of particles. [br][/br]- Low power consumption.[br][/br]- Equipped with modern ACS and online control panel, job analysis system, logging and statistics collection system which consider different options and the required parameters of final product.[br][/br]- Control of grinding fineness and product size distribution without a stop in operation of the complex. [br][/br]- Individual configuration depending on the properties of the materials, the size of products, the requirements for weight and size characteristics.[br][/br]- Possibility to integrate into the operating production lines.

Range of Applications
Grinding complexes are applied in the production branches which are involved in the manufacture of high quality fine powders:[br][/br]- mineral raw materials[br][/br]- dry building mixes ingredients[br][/br]- weighting agents[br][/br]- refractory and abrasive mixtures[br][/br]- pharmaceutical and chemical components.[br][/br][br][/br]They are applied to grind the following materials: electrocorundum, limestone, gypsum, graphite, brucite, ferrous slag, clinker, slag, marble, talc, coal, schungite, periclase, calcite, bentonite, quartz, dolomite, barite, mica, wollastonite, glass, ammonium polyphosphate,...[br][/br][br][/br]Grinding complexes are applied for fine and ultra fine dry grinding of the materials for which of great importance are such attributes as product quality, its homogeneity, the absence of impurity elements.[br][/br][br][/br]It possible to obtain simultaneously several classes of powders.
