First, let us introduce the overall layout for you. One of the most important principle of design is to reduce the axial length of the device. In order to achieve this goal, the driving device and the spindle should be arranged in vertical direction and advanced hardened reducer should be used in the reducer. At the same time, the bilateral ratchet device should be replaced by the backstop and installed on the high-speed shaft of the reducer because of the small driving power (55kw), short belt and small angle. In this way, the axial length of the device is minimized to meet the design constraints.

The permanent-magnetic cylindrical type separator is widely used in the magnetite separation, recycling magnetic heavy medium, and the mine pre-selection of the wet type high-intensity magnetic separator and high gradient magnetic separator. This section mainly introduces the permanent-magnetic cylindrical type separator. The CTDG-1220N permanent magnetic chunk of ore separator is added by the driving device that is composed with the reducer and motor besides magnetic system, simplified style, rack, bearing, ore separation equipment, and magnetic system debug device. The main features and design principles are as followings.

At last, let's discuss about the determination of the width and the speed of the belt and the uniformity of the fabric. The processing capacity of the CTDG-1220N bulk ore dry magnetic separator in up to 500t/h which is the permanent dry magnetic separator with he high processing capacity in China. In order to achieve this processing capacity, 2m wide belt should be used if the largest handling block is 75mm and the belt speed is enhanced to 2m/s. In this way, the thickness of the material on the belt is not more than 200mm to ensure the full load. Since the material is transported to the separator from a concave belt conveyor of 1.4m, serious accumulation of the ore will happen which will affect the sorting effect if active measures are not...
