The literature that the use of laboratory-level disc granulator machine for cold bonded pelletization method, many variables affect the performance of granulation, such as selection of raw materials, additives, additive content, granulating machine sets its own parameters, different powder mix Methods and human error[8].
Bonding mechanism of bentonite, bentonite particles combined with water will begin to swell, and powder have granulation and mix process get a shear direction , so bentonite surface have produce fiber, good with raw materials combined[9].

Key Lab of Modern Metallurgy & Materials Processing, School of Materials Science and Engineering, Shanghai University, Shanghai, 200072, China *qdzhong@shu.edu.cn Keywords: polymer coatings, steel, alkaline, corrosion, semiconducting Abstract：The semiconducting behavior of No.20 carbon steel coated with different polymer coating in 5% sodium hydroxide solution was studied by utilizing potential-capacitance and Mott-Schottky analysis.
Introduction It was well known that organic polymer coatings were typical insulating materials, and electrochemical and corrosion behaviour beneath the coatings have also drawn many concernings [1-4], till now, it is also a hot topic for electrochemical and corrosion studies, especially in some specific area, such as in alkaline solution [5].

(3) Materials procurement analysis Whether the materialpurchased is energy-saving is the main influencing factor.
Within the system boundary of this study, the application of building materials is mainly considered, but the energy consumption in the production processfailed to reflect.
Due to the impact of system boundary and the samplerange,there are limitations on energy consumption of building materials, recycling of construction waste.
