Established in 1991, Jiaozuo Zhenjieneng Environmental Protection Equipment Technology Co., Ltd. Specializes in technology research, equipment manufacturing and project engineering for all kinds of high humid and viscous materials drying. 

Pickling sludge is a general term of a kind of sludge produced by waste water which is produced by metal surface treatment process and neutralized by lime. Pickling sludge generally contains heavy metals such as iron, nickel and chromium. According to the principles of recycling, innocuity, reduction and low carbonization of sludge disposal, it is necessary to dry the pickling sludge before recovering precious metal resources. Jiaozuo ZJN Environmental Protection Equipment Technology Co., Ltd. is specialized in the research and development and manufacture of sludge drying equipment. The "Rotary Harrow Rolling Triple-level Multi-loop" and "Automatic Rake-turning Segmental Combined" series of high humidity and high viscosity pickling sludge dryers produced by our company can be tailored for pickling sludge with different compositions and manufactured elaborately. After extracting precious metals, the dried sludge can be put into a combustion furnace for incineration treatment, and can also be used as raw materials for building material production, etc. Suitable is the best, ZJN Pickling Sludge Dryer, a well-known brand! Welcome to choose!

The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs.
It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
