Bentonite Clay

Bentonite is a clay from the Smectite group that mainly consists of montmorillonite which is a composed and plastic clay by nature. It is obtained as a result of volcanic eruption, the ash that evokes out and alters to form a bentonite clay. The clay got its name from a knight as it was shipped in the name of Taylorite in the year 1888. In the previous years, its use and application was not known much to the people; though the production made was few tons a year. But with the progressing time, bentonite is applicable to many of the industries type and therefore its production has now jumped to some million tons a year. One may either find a sodium or calcium compound in bentonite that can be widely used by industries.

Types of Bentonite

Bentonite can be called as a clay in general as it actually a dirt but with wider applications in industries and useful to common people. The clay is mined and powdered to form a light brown clay which is actually obtained as a result of volcanic eruption. One will mainly find two different kinds of clay: Industrial and food grade. Chemically bentonite is either Sodium Bentonite or Calcium Bentonite. The clay also comes with some other minerals in trace amounts and they are present in the clay in different proportions.

Sodium bentonite has an external use only because of its property of absorption. It has capacity to absorb much more than required and it is accidentally swallowed then it can lead to swelling in the stomach or intestine. The clay sodium bentonite is mainly used for industrial purpose only and in case of application on the body, it is strictly used externally. On the contrary, calcium bentonite does not swell much therefore it can be consumed by people. It is this bentonite that people use for their intake which we call it as food grade.

Role of Bentonite in various Industries

Piling

Piling

In the process of boring, the side bores will have to handle many kinds of pressures. The pressure from earth, the overburdened pressure, hydrostatic pressure exerted by the underground wate, etc, due to which the side bores may lose its stability and begin to collapse. If the ground strata are weak then the soil may loosen begin to fall away leading to shaking platform for bores. Hence to support side bores from the pressure that it takes, bentonite slurry is added as a supporting fluid.

Drilling Grade

Drilling Grade

Nilco Impex is one of the suppliers to oil and petroleum industries and it mainly provides drilling materials to them. As we are one of the leading miners and suppliers of Bentonite, we provide these sectors with drilling grade Bentonite. Raw Perlite is used for expansion whereas Micrasil is used for better cementing is also provided by us.

Bentonite has a property of forming slurry when mixed with water that can be pumped in and out through the drilling system. It helps in not only cooling and lubricating the drill but also in sealing the drill holes. The drilling grade Bentonite manufactured by us has a property of forming colloidal in nature that results into increased viscosity. Increase in viscosity will lead to smooth drilling and better efficiency.

Foundry

Foundry

Almost all of the cast iron, steel and malleable iron foundries make use of bentonite because of its properties and uses. The most sought after Bentonite is way more cost friendly than other materials used in cast iron industries. Our foundry grade Bentonite yield green sand mold that has better flowing ability and thermal stability which is important as the process occurs at really high temperature. Our Bentonite is mainly used in molding sand for iron, steel and non ferrous casting as it has better flowing and molding ability. Sodium Bentonite and Calcium Bentonite both have the ability to bind and mold the casting iron, steel or other non ferrous metals. At the end of the process, Sodium Bentonite is also used as a cleaning agent as it removes all the remaining impurities.

Cat Littars

Cat Littars

Bentonite as a cat litter, Does that surprise you? Well, may be yes but it is true that cat litter contains bentonite clay that clumps together when it is moist. It is found that around 69% of litters for cats is nothing but Bentonite litters and in no time it became a successful one in the market. Bentonite has the property of absorbing moisture therefore it can form clumps that can be easily removed leaving the good ones in the packet. It is also seen that it is good for a cat's health and it avoids the risk associated with the surrounding.

Animal Feed

Animal Feed

Most of the animal feed type has included Sodium Bentonite as one of the ingredients owing to its benefits. It is said to have formed a gel during the process of digestion in animals that leads to having a better digestion capability. It also prevents protein degradation so as to make digestion effective and make all the nutrients available to animals for their growth. Sodium Bentonite forms a coat on the feed particles that prevents fermentation and avoids the risk of acidosis in animals. It has the capacity to neutralise lactic acid formed with the release of cations that prevents ruminal acidosis. Almost all the animal feed can include Bentonite in a given proportion of 2%- 4% in starter rations and about 1%-2% in finisher rations. Bentonite binds with urea and prevents risk of urea poisoning and leads to efficient conversion of proteins into simpler compounds. The flow in saliva in the rumen of animals will lead to considerable benefits in digestion. Sodium Bentonite is an ingredient in the feed of poultry, pigs, dairy industries, and other kinds of animals.

Bentonite Clay

Electric Earthing

Bentonite is a clay that has moisture retaining capacity hence it is used as an earth electrode - back-fill to lower the resistivity of soil. Sodium activated montmorillonite is a conductive bentonite that swells up to several times when mixed with water at dry conditions. The earthing grade Bentonite is non corrosive and stable compound that will retain its shape and property for years. It can absorb moisture from the surrounding soil resulting in reduced contact resistance and increase in size of the copper earth rods installed in earth that contains Bentonite filling. The granular form of bentonite is a prefered choice for filling trenches whereas powdered one is used in filling bore holes to ensure that everything is covered properly.
