The production is mainly to adjust the magnetic separator to blow off the water and unload the flushing water. The blown water is too large, the tailings grade is increased, the blown water is too small, the tailings grade is low, and the concentrate grade is also low. The appropriate amount of blown water should be determined according to the nature of the ore, the amount of ore and the operation requirements. Do not block or run during operation. Over 1% reward production class 30 yuan / time. In the production, because the magnetic separator enters the obstacle, the production class is 100 yuan/time when parking or scratching the barrel.

11, high gradient magnetic separator station

High-gradient magnetic separation is the main equipment in the plant, and the operation must be carried out in the order of opening and stopping. After stopping the magnetic disconnection, it must be idling for more than 2 minutes, and the magnetic material accumulated in the magnetic separator is flushed out before the water shut-off is allowed. Because of the misoperation, the magnetic circuit is blocked and the production class is 50 yuan/time. The cooling water outlet temperature shall not exceed 70 °C. If the water temperature exceeds the specified level during the inspection, the production class shall be 50 yuan/time. The grade of TiO2 concentrate of high gradient magnetic separator is controlled at 27±1%, lower than 26%, and every 1% drop, the production class is 40 yuan. The concentrate grade is higher than 28%, and each increase is 1%, and the production class is 40 yuan. The tailings grade is controlled at 4±0.5%, the tailings grade is greater than 4.5%, and each increase is 1%, and the production class is 40 yuan. For every 0.5% drop, the reward production class is 50 yuan.
