he client mainly manufactures comprehensive electric furnace zinc powder zinc powders, blown zinc powders and other metal powders. This project was charged by SKE. And our jobs are to upgrade and transform the old conveyor system for the harmless treatment of zinc smelting tailing and the comprehensive recovery of valuable metals.
1. Project in the area of high altitude : the rated parameters of all electrical equipment must be guaranteed to meet the requirements for application.
2. High equipment reliability requirements: 24 hours of continuous operation must be guaranteed, annual working day: 330 days.
3. Equipment diversification: There are three types of bulk material conveying equipment used in this project: fixed belt conveyors, mobile reversible conveyors, and corrugated flange (large inclined) belt conveyors.
4. Strict belt cleaning requirements: There are a variety of materials involved in the production and processing of non-ferrous metals, and the same belt conveyor needs to transport different materials, which has strict requirements for belt cleaning.
1. Temperature: The average annual temperature is 4.9 ℃, the extreme maximum temperature (annual maximum temperature) is 38.7 ℃, and the extreme minimum temperature (annual minimum temperature)-31.7 ℃.
2. Earthquake intensity: 7 degrees
3. Altitude height: 2600 meters
4. Annual average relative humidity: 35%
