We specialised in manufacturing and supplying of perforated metal and perforated screen products. Perforated metal & sheet can be used in a range of applications, including filtration in oil & gas, petrochemical industry; separation and filtration for waste water & sewage treatment and drainage systems; perforated ceiling panels, perforated facades, perforated balustrades for architecture and building industry; perforated sieve & screen for cleaning, sorting, grading, drying of seed, grain, cereal, coffee, corn, maize, rice and legumes; hammer mill screen, grinder screen for grain milling, flour milling, animal feed milling and other grinding milling industry; cookware for food service application; and many other general industry use. We aim to offer reliable perforation solutions and excellent customer service.

Bentonite as is a particular kind of clay derived from volcanic ash and consists mainly of montmorillonite with minor amount of illite, kaolinite, cristobalite and other minerals. Bentonite has strong colloidal properties and, when in contact with water, increases its volume several fold by swelling, forming a tixotropic, gelatinous substance. Main uses of Bentonite take advantage of these colloidal properties. The main characteristics of Bentonite is its decolorizing power, that is the property of the earth to absorb selectively certain pigments rather than others according to the characteristics of the product to be decolourized(acidity, oxidation degree, origin and biological state etc.)

APPLICATIONS

For Drilling Fluids
Pilling
Binder (e.g. foundry-sand bond, iron ore pelletizer)
Purifier
Electrical Earthing
Agriculture
Cosmetics, Paper, Paints and Ceramics
Absorbent (e.g. pet litter), and
As a Groundwater Barrier.
We CEMENTATION acquire own mines for Bentonite in India. We supply Bentonite for industrial, manufacturing, construction and drilling applications. Our production or supply capacity is more than 250,000 TPA.

At CEMENTATION a special attention is given while mining Bentonite as the materials physical and chemical properties are depended upon the interference of the other metal ions present in the soil.

Once the material sourced from mines are transferred to our factory and are left for drying in an open land to reduce moisture up to the desired level. After the drying process and other checks are done our skilled manpower will do a sorting of the material and then after the material goes to pulverizes for grinding to desired mesh size and are packed according to customers requirement. Our laboratories are well equipped to meet the needs of the diverse markets we serve.
