As the core equipment of the firing system of cement production line, the length of rotary kiln after transformation in Saudi Arabia project87.3m, with a maximum weight of 178tThe hoisting section is the longest21.5 m; according to the on-site construction environment and mechanical personnel configuration, after many calculations, our project department finally decided to use 400 tons of crawler crane and adopt the hoisting scheme of 60 meters main arm + 200 tons overlift.. The project department overcomes the narrow site, cross construction,There are many unfavorable factors in the unloading of the new wheel belt of the rotary kiln and the ground group, among which the biggest difficulty in this hoisting is the hoisting of the middle wheel belt (inner circle diameter).7870mm, outer circle diameter 9180mm, weight up to 150T,), before hoisting, the wheel belt needs to be hoisted to the standing state in the flat state and find a good tilt angle, and the gap between the wheel belt cushion plate is small, so it is impossible to use thick wire rope. After many calculations, it is decided to use diameter 37mm wire rope to hoist at a rate of 16 times under 6 times safety factor. Based on insisting on respecting the technical hoisting scheme，In kiln squad and hoisting squadThe closeness of personnelWith the support of the180 hours of struggleSuccessfully completedRotary kiln hoisting operation.
Because the supporting equipment of the rotary kiln is all obsolete, and the idler after removal/ tugboat bearing, etc. have varying degrees of wear, the supporting wheel and the supporting wheel bearing all need to be repaired on site. The successful completion of the hoisting of the rotary kiln with the combination of the new and the old not only demonstrates the technical ability of the installation and transformation of large-scale equipment in the company's cement system.?At the same time, it also gotYAMAMA cement CEO?Mr.Jehad and Senior Vice President Abdullah?.AlnwaserA high degree of praise and evaluation, for the company to open up the Middle East market to set up a new brand.
