Rotating spiral chute infos rotating spiral chute is a combination of spiral concentrator, features shaker, centrifugal concentrator, is a high-efficiency "overlay" style performance of re-election equipment. In addition to having a spiral chute general characteristics, but also with a reasonable structure, processing stability, sub-ore clear, large capacity, crusher manufacturers, high efficiency beneficiation enrichment ratio, high recovery rate, running and reliable. The difference between the rotating spiral chute and general spiral chute is a spiral groove around the vertical axis of rotation, the particles subject to greater centrifugal force and shorten the process of sorting the necessary distance, increase productivity. Mineral particles in the slot surface by hydrodynamic centrifugal force, friction, gravity, and other composite force field difference being sorted. Its sorting action from three aspects: first, because the speed of the rotating spiral chute by a certain cause in the process of sorting, the underlying heavy mineral slurry flow in the opposite direction by the frictional force along a particular direction, to heavy minerals inertial force tangent motion increases, while the normal direction of the force is small, resulting in conditions of heavy minerals along special grooves to concentrate strip or band (inner edge) movement. In the process of sorting the light minerals located on the upper surface of the spiral chute, by friction is small, because the spiral chute rotation velocity is large. While the strong role of the high-speed flow, light mineral was quickly pushed outward into the tailings zone. Second, the groove surface of a particular section or groove, and with screw diameter angled Shanghai crusher, spiral chute and rotating at a certain speed, forcing heavy minerals, especially heavy minerals make cylindrical stop toward the inner edge of the spiral groove distillate movement. So that the recovery has been greatly improved. Light mineral in constant motion while the outer edge of the spiral belt into the tailings. Third, since the rotation of the spiral chute, in addition to increasing the inertia of heavy minerals, increased light mineral centrifugal force, but also to make the bottom groove surface against heavy minerals along with a special motion to strip or groove concentrate. A simple understanding of the two with the ball mill method called two with the ball method, it is to use the size of the two different specifications, and both the diameter difference between the larger ball for grading. On the theory that a large gap between the ball from small balls to fill in order to fully enhance the bulk density of the ball. Thus, one can improve the impact strength and impact of the number of the first positions, in line with features that bin grinding media, on the other hand, higher bulk density can be able to get some material abrasive. In two match balls, big balls main function is the material for impact crusher. First, the role of small ball filling the gap between the big ball, increasing the bulk density of the grinding media to control the flow of materials, increase grinding capacity; the second is the role of energy transfer from the large ball impact energy transfer to the material; the third is the gap The coarse particulate material squeezed out and placed in a large ball of the impact zone. In the multi-stage with the ball in for the ball impact, impact times, the ability to control material flow requirements are based primarily on average ball diameter, that is subject to a variety of specifications ball in. In the two-stage with the ball, the ball's impact, impact of the number determined by the large diameter of the ball, and the ability to control the flow of materials is mainly determined by the diameter, filled with a small amount of the ball, and the influence of the big ball diameter is small, and therefore easing the impact, frequency and control the impact of conflict between material flow capability. In contrast, the two-stage method is relatively simple with the ball, drying crusher, when determining grading parameters considered easy to do. From production changes, along with the material hardness and grain size increases, conflicts with the ball in the performance of multi-level impact and material flow control ball between the more prominent, crusher specification, so production is more pronounced decline . In the two with the ball in this conflict does not exist, because it can be big, small balls to satisfy the material to impact and flow control capability requirements, and therefore production did not change significantly, reflecting the superiority of two with the ball .
