2results about How to "High iron removal efficiency" patented technology

The utility model discloses white corundum iron removal screening device, and the device is constituted by magnetic separator body, magnetic screening conveyer and material flat laying mechanism. The magnetic separator body is equipped with the rack for supporting, and the inside is provided with the iron impurity conveyer for receiving the iron impurity, and the front end places the white corundum hopper. The magnetic screening conveyer is fixed in the rack through the hanger, and the magnetic roller is driven to rotate by the driving motor, and then drives the conveyer belt to run, realizes the conveying of material, and the magnetic roller can adsorb the iron impurity. The material flat laying mechanism is installed at the top of the magnetic separator body, and the cylinder can adjust the telescopic shaft position according to the feedback of infrared distance sensor, makes the comb material grate comb the white corundum material on the conveyer belt and lay flat, improves the iron removal effect. The iron impurity falls into the iron impurity conveyer and is carried away after separating from the magnetic adsorption, and the pure white corundum material falls into the white corundum hopper, and the screening and iron removal operation is completed.

This invention discloses a combined device for removing trace amounts of iron from ceramic raw materials. It includes a primary iron removal system and a secondary iron removal system. The secondary iron removal system includes an outer cylinder with a support cylinder that can rotate counterclockwise. A raw material distributor (4) is fixed on the inner wall of the outer cylinder between the support cylinder and the raw material feed pipe. Electromagnetic blocks are fixedly arranged at intervals on the surface of the support cylinder. The electromagnetic blocks are divided into abcd region and ad region on the cross section of the support cylinder. A wedge-shaped pressure block is arranged on the support cylinder at point a in the ad region. An arc-shaped contact plate is arranged on the end plate of the outer cylinder. The primary iron removal system includes two crushing and iron removal rollers that rotate vertically relative to each other. Each crushing and iron removal roller includes a rotating cylinder with comb teeth. A strong magnetic plate is fixedly arranged on the rotating cylinder between the comb teeth. This invention saves cleaning materials and labor time, reduces iron removal costs, and has a good iron removal effect, which can reduce iron content in raw materials by 60-70%.
