Installation method

XJK mining flotation machines, BS-K type aeration flotation machines, and CTB series magnetic separators must all be installed on a sturdy concrete foundation that can support the equipment's own weight and dynamic loads during operation. During installation, ensure the foundation's level meets requirements, and anchor bolts are tightened according to torque specifications. After positioning the equipment, adjust the level to ensure the impeller or magnetic drum is parallel with the motor shaft. The motor and gearbox are connected via belt or direct coupling, and belt tension or alignment accuracy should be adjusted to ensure smooth transmission. Flotation machines must ensure that the slurry and reagent inlet and outlet pipelines are securely sealed; aeration flotation machines should connect to the blower pipeline, allowing adjustable air volume. Magnetic separators must ensure feeding and discharge pipelines are securely sealed to prevent slurry leakage. After installation, a no-load test run should be performed to check whether the impeller or drum rotates smoothly and for any abnormal vibration or noise. During the load trial run, gradually increase the feed volume while observing the separation efficiency and motor current to ensure it does not exceed the rated current. Dust removal systems should be equipped to reduce dust pollution. A central control system can be installed for online monitoring and automatic control.
