From a big piece of block to a fine grain of very low granularity, the ores must be through various processes. Here, SBM provides solutions satisfying all types of ore processing For general projects, we create standardization and forge profession by standards; for customized projects, we actively cooperate with institutes and build standards by professions.
Iraq 60000tpy gypsum powder production line
This line was purchased in 2012 and was a project of local government.
The milling system has two MTW 138 with fineness of 100 mesh. The output of each unit is 13tph. One is used for routine production while the other is used as back-up.
The crusher smashes the natural large gypsum ore into small pieces of less than 30mm which shall be then stored and conveyed to the grinder for grinding into powder with feed rates under controlled by electro-vibrating feeder. The powder shall be screened with powder separator to get the required fineness. The qualified raw milled powder shall be conveyed to the fluidized bed combustion boiler for calcinations. The qualified gypsum powder after calcinations shall be delivered to the clinker warehouse or to the manufacturing workshop for using.
The system structure features
A. Advanced technology, mature and stable process, broadly used in gypsum board production line domestically and overseas;
B. The selected equipment is reliable in quality and capable of development and over production with little and easy maintenance;
C. Good sealing property, high efficient dust-removal and free of dust pollution;
D. Compact equipment occupying little land areas;
E. Full integration and automatic control system, reducing the on-site labor numbers and work intensity.
The Iraqi governmental projects are mostly cooperated with European and American companies. It is the first try to use Chinese equipment by establishing business relations with SBM. All the fineness, initial setting time, final setting time and rupture strength of the finished gypsum powder meet with national standards and have won good feedback in domestic gypsum building material industry.
