The Xizang Gaozheng aggregate production line is invested and constructed by Xizang Gaozheng Building Materials Group, designed and supplied by Hunan Building Materials Design and Research Institute Co., Ltd., and is the general contractor of Tianjin Mining Engineering Co., Ltd. for the construction of the aggregate production line with an annual output of 1 million cubic meters. Our company is responsible for the installation and construction of electromechanical equipment for this project. The installation project is planned to start on March 10, 2017, and the third production line of Gaozheng Cement will be put into operation in the second quarter. In order to increase the original limestone crushing production capacity, it is necessary to renovate the original limestone crusher, plate feeder, belt conveyor and other equipment. In order to successfully complete the renovation project of this project, our company dispatched elite soldiers to overcome unfavorable factors such as altitude sickness, severe weather, and geographical conditions, and actively devoted themselves to the work. The renovation project of this project has been completed in three phases. So far, the first phase of the renovation of the old line limestone belt has been successfully completed and put into operation. The steel structure and non-standard parts production project are in intensive progress, making sufficient preparations for the later renovation project.
