The main technical indicators of belt color sorter

Belt color sorter is widely used in food and resource recycling processing.

1.The processing capacity.

The processing capacity is the amount of materials that can be processed per hour. The main factors affecting the processing capacity per unit time are the movement speed of the servo system, the maximum speed of the conveyor belt and the purity of the raw materials. The fast movement speed of the servo system can quickly send the actuator to the position corresponding to the impurity, which can also increase the speed of the conveyor belt and increase the processing capacity, otherwise the speed of the conveyor belt must be reduced. The processing capacity per unit time is directly proportional to the moving speed of the conveyor belt, the faster the conveyor belt speed, the greater the output. The processing capacity per unit time is also related to the proportion of impurities contained in raw materials. If there are few impurities, the larger the interval between two impurities, the longer the reaction time left for the servo system, and the speed of the conveyor belt can be increased. At the same time, the processing capacity per unit time is closely related to the required selection accuracy.

2.Color sorting accuracy.

Color sorting accuracy refers to the percentage of the number of impurities selected from raw materials to the total amount of impurities contained. The color sorting accuracy is mainly related to the moving speed of the conveyor belt and the purity of the raw materials. The slower the moving speed of the conveyor belt, the longer the time between adjacent impurities. The servo system has enough time to remove impurities and improve the color sorting accuracy. Similarly, the higher the initial purity of the raw material, the less the amount of impurities, and the higher the color sorting accuracy. At the same time, the color selection accuracy is also limited by the design of the servo system itself. When there are more than two impurities in the same frame of image, only one impurity can be removed, and the color selection accuracy decreases. The multiple selection structure is better than the single selection structure.

3.The take-out ratio refers to the ratio of the amount of impurities in the waste selected by the color sorter to the amount of normal materials. The level of the take-out ratio can be adjusted, and the adjustment of the take-out ratio is mainly completed by adjusting the energization time of the actuator. If the take-out ratio is set too high, it will affect the two indicators of selection rate and processing capacity; if it is set too low, the selected waste contains too much normal material, which will cause waste; if it is reprocessed, it will need to invest A certain amount of manpower and material resources will cause a lot of trouble and economic loss.

In the actual production process, the three indicators of processing capacity, color sorting accuracy and take-out ratio are integrated, and they are all key indicators, which must be investigated at the same time.
