Feeding device of quartz sand color sorter. The traditional vibration principle is abandoned for feeding. This ore color sorter adopts extended vibration structure, with reasonable vibration angle and effective vibration frequency. Through multiple tests, it is verified that its reasonable feeding method not only greatly improves the output, but also improves the color separation effect. Feeding device. It subverts the traditional methods (waterfall type and crawler type). It does not need to replace the chute and belt, and is more stable and guaranteed.

Color sorter. Long distance high-definition camera can be used to shoot at a large distance, which can make the principle of shooting collection area large dust area, effectively solve the problem of production cleaning time, improve production efficiency, and greatly increase the output. Light source device. The independent light box processing mode enables the lights in the large dust area to clean the dust without stopping, which is suitable for assembly line production. Drive unit. It is the same as the traditional pneumatic type, but the spray valve with larger gas volume is used. The powerful blowing parts can ensure that materials within 100mm can be color selected, which greatly improves the output.

The color sorter can be said to be a "robot", which is mainly composed of four systems: feeding - transmission - detection - sorting. Its performance evaluation indexes mainly include the following points: treatment capacity; Color selection accuracy; Take out ratio and selection rate. If the relationship between the indicators is not well understood, the effect of color selection is inevitably unsatisfactory.

In the actual production process, these indicators are integrated and have mutual influence and restriction, which must be investigated at the same time. The main factors that affect the precision of color separation and the amount of processing per unit time are the motion speed of the servo system, the maximum speed of the conveyor belt and the purity of raw materials; The carry out ratio can be adjusted. If the carry out ratio is set too high, the selection rate and processing capacity will be affected; If the setting is too low, the selected scrap contains too much normal material, which will cause waste.

Different applications have different requirements for raw materials, so we must not only pursue the output. Take the most commonly used quartz sand as an example. If it is used for making quartz plates, we must not be careless. The quartz sand used for quartz plates must be pure white and acid washed. There must be no yellow skin on the surface of quartz sand. The hardness of stone is also better. It is white and transparent quartz sand, The quartz plate made in this way can meet the industry standards.
