Jiaozuo ZJN Customizing Large Pulp Dryer is the first choice for energy conservation. Our company is an energy-saving and environment-friendly enterprise that actively devotes itself to the comprehensive utilization of "three wastes", uses waste to treat waste, and is full of social responsibility. "Rotary Harrow Rolling Fast Pulp Dryer" is a patented product of Jiaozuo ZJN Environmental Protection Equipment Technology co., ltd. It has passed the examination and approval of various national patents. ZJN Customizing Large Pulp Dryer is different from the previous drying process and uses boiler tail gas as its drying heat source. The waste liquid, waste residue and waste materials generated in the production process of the enterprise are put into use, thus breaking the traditional coal-fired drying method and greatly improving the economic benefits of the enterprise. The dried finished products can be used for agriculture or fuel. The traditional coal-fired drying method not only consumes large amount of coal, but also pollutes the environment. In the current drying industry, there are still problems such as large investment, high energy consumption, low efficiency, etc. The true energy-saving pulp dryer is advanced in technology, stable in equipment operation and convenient in installation and debugging. Welcome to our company for inspection and order products. ZJN is looking forward to cooperating with you!

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.
