This unique property is also certified by several international organization like EU commission, regulation no 3862009. 6.Our selective mined material contain very low amount of heavy metals, you can say it very much less than the permitted levels, most important things is the DIOXYGEN which is zero. Applications: 1.It is recommended to use FEEDWELL as binder for all animals.

We are offering earthing grade bentonite. Earthwell the common practice of making a good ground bed for earthing is to use coal, salt (nacl) and water but these formula has some limitation. Our product called earthwell is a bentonite based earthing material. Why this product: normal salt sodium chloride is highly corrosive in nature, it have a negative effect on electroplate, again it hygroscopic and dissolve in water hence easily washed away, require recharge by time to time if not then face fault. The other component is coal which has a tendency to become ash with high heat again the ash canâ��t hold water, result earthing pit fault. Our product has a good water holding capacity which ensure good ion despite by means of ion exchange with electron. advantages: • it can absorb up-to 1000% of water. • can maintain the moisture for long duration no need to recharge. • no need to add extra salt or coal, it’s a readymade product to use. • non corrosive product, no corrosion of electroplates. • reduce soil resistivity. • easily compact. • allows least ohomic value fluctuation. • good capacity to clear the fault current and helps to overcome electrical hazardous. • even can use at desert area. how to use: • it’s recommended to mix with fresh water available at the site. This will holds its shape and adhere to the walls of the electrode to provide a direct contact between the earth and the electrode. With its ability to retain the water the compound always hydrated within the bed irrespective of the surface temperature. • in case of cost effective mix at least 40% of compound with site’s soil and fill the pit then watering the pit for good result use layer formation to watering.
