Supplier From China
Aug-12-16

In agriculture, vermiculite can be used as soil conditioner. It develops the soil permeability and water content, makes acidic soil change into neutral soil.

Exfoliated vermiculite plays a very good heat insulating effect, making the building warm in winter and cool in summer.
In gardening, vermiculite can be used for flowers, vegetables, fruit cultivation, breeding and other aspects.

Product Details
Vermiculite is a kind of natural, non-toxic, inorganic silicate mineral, whose raw ore looks like mica. Vermiculite is formed by the hydrothermal alteration or weathering of minerals, usually biotite and phlogopite. When heated, it expands like leech. Vermiculite are divided into raw vermiculite and expanded vermiculite by stages, and according to the color, it can be divided into golden vermiculite, silvery white vermiculite, milky white vermiculite.
Exfoliated Vermiculite

Vermiculite, with layer construction and interlaminar water. It begins expend when it is heated over 200??, becoming the worm-like shape and it can be 15-25times bigger than the original volume, maximum 30 time. when it is rapidly heated to 800??. This forms the material with low density (100-300kg/m), excellent insulation property and good hydroscopicity and ion exchange capacity.

We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.

At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.

The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%


From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:

Waste code: 10 02 10

The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.

Chemical analysis of the material is available on request.
