A sand making equipment and method with controllable stone powder content
This invention relates to the field of sand making technology, specifically to a sand making device with controllable stone powder content. The device includes a return conveyor tailstock, a sand making structure on the side of the tailstock, a primary filtration structure inside the tailstock, and a secondary filtration structure on the side of the tailstock away from the primary filtration structure. The stone powder is initially filtered by the up-and-down vibration of a moving block. When a specific size needs to be filtered out, the pneumatic bar valve moves, driving the inverted V-shaped guide plate to a parallel state. At this time, the first telescopic plate continues to move, changing the parallel guide plate into a regular V-shape, causing the stone powder on the guide plate to contact the interior of the return conveyor tailstock. This reduces the volume and irregularity of the splashed stone powder through collisions, and accelerates the guidance of the stone powder towards the pneumatic bar valve for filtration, thus improving production efficiency and the filtration effect of the pneumatic bar valve.
