Ball mill appeared in the early 19th century;

Ball mill is the material being broken, and then smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ore dressing, and black glass ceramic and other non-ferrous metal production industries, and other various ore grindability of materials for the dry and wet grinding. Ball mill is a horizontal rotating device, outer gear, the two positions, lattice-type ball mill. Material from the feed device into the compound by air evenly into the mill screw shaft first warehouse, the warehouse there are ladder liner or corrugated liner, built in different specification steel balls, cylinder to convey ball into the action must generate centrifugal force After the fall height, produce severe impact on the material and abrasive. To coarse grinding of materials in the first position after the board by the single compartment into the second warehouse, the warehouse lined with flat lining, steel ball inside, the material to further grinding. Powder discharged through the discharge grate plate to complete the grinding operation. Structural characteristics of ball mill from the feeding part, discharging Department, Rotary Department, Transmission Division (reducer, small transmission gear, motors, electrical control) and other major components. Hollow shaft with steel casting, lining Replaceable, slewing gear hobbing by casting process, the body inlaid cylinder liner wear, has good wear resistance. Ball mill energy consumption in the course of work accounted for the majority of the whole process of cement production, including power consumption, integrated power consumption of cement accounts for about 60% -70%, so how big the energy consumption of 'downsizing' is a cement technology workers unremitting goal. Grinding equipment selection, based on cement and concrete properties (performance,mechanical properties, durability) as the core, not just the pursuit of the production process of reducing power consumption, but also to meet the needs of building energy saving. 'Standard density is low, a good additive compatibility, well age, high strength, help to improve the durability of concrete is the quality of cement concrete.' At the same time, also ensures the development of admixtures industry view, 'admixture of cement industry can reduce the required particle bound to improve the performance of cement plays an important role.'
Carbon Molecular Sieve for Food Preservation
Food Preservation Nitrogen Generator is a high-purity nitrogen generator specially designed for the food packaging and preservation industry according to the advanced PSA pressure swing adsorption principle, using carbon molecular sieve to separate nitrogen and oxygen from the compressed air. Provide dry and continuous pure nitrogen for food packaging, beverage stirring, fruit and vegetable storage, cereal fumigation, food nitrogen puffing and other purposes , energy saving and so on.
More Information on Molecular Sieves.
Molecular Sieves are sorts of desiccants that have varying properties from those of silica gel. These materials are artificially created of exceptionally permeable translucent substance made of metal-aluminosilicates. The appearance is of minuscule obscure pinkish globules made of a few inside holes interconnected by window openings of exact distances across.
Activated Alumina for Fluoride & Arsenic Removal
Activated alumina fluorine removal agent is white spherical, with high fluoride capacity, good physical properties, high strength, non -toxic, tasteless, soaked in water without weakness, not swelling, no rupture, completely reliable use, easy regeneration, long service life.
New automatic production line for molecular sieves with an annual output of 5,000 tons
In order to improve the influence and competitiveness of molecular sieve products in the industry, our company has built a new set of zeolite molecular sieve automatic production line with an annual output of 5,000 tons, which has solved the long delivery cycle and instability of product quality for customers.
Carbon Molecular Sieve for Nitrogen Tyre Inflator
Xintao's carbon molecular sieve is widely used in nitrogen generator , with high hardness, less ash, uniform particles, and high cost performance. The models selected by customers are usually CMS-240, CMS-260. The nitrogen concentration is 99.5-99.99% and above, which has won a series of praises from customers.
Paint resin industry
Activated molecular sieve power is dehydrated synthetic powerdery molecular sieve. With the character of highdispensability and rapid adsorb ability; it is used in some special adsorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc.
