Preparation of aerated concrete material relationship with aerated concrete feed mill in the most important equipment is the ball, rotating cylinder in the process, the grinding media have dropped the phenomenon, in the fall during the feed material to the abrasive action, in order to effectively utilize abrasive effect, end the material for grinding steel, grinding the material passing discharged from the discharge end of the hollow shaft, small particles of feed material were finely ground when the machine is a horizontal cylinder rotating mechanism, Beijing grader, outer gear, the two positions, lattice-type ball mill. Built with different specifications steel ball, ore grading machine, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive. The material in the first position coarse grinding, the material to further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation. Only material to the required fineness of grinding and only after mixing interaction, in order to make products to strength, grinding production of aerated concrete is an important program, a ball mill is a horizontal simplified, out of the hollow shaft and grinding head parts, simplified for the long cylinder, to be selected according to the particle size of milled material, material from the mill feed end of the hollow shaft into the cylinder body, when the ball is rotated simplified, because of inertia and centrifugal force, the role of friction grinding , making the cylinder liner near the posts were taken away cylinder, ball mill used by the feed device into the compound evenly into the air shaft spiral mill first warehouse, there are ladder liner or corrugated liner warehouse , built with different specifications steel ball, rotating cylinder produces centrifugal force after the ball a certain height After the fall, have severe impact on the material and abrasive. 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, 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 caused by certain specific direction in the sorting process, the underlying heavy mineral slurry flow in the opposite direction by the frictional force, powder classifier to inertial force tangent movement of heavy minerals 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 spiral chute and rotating at a certain speed, forcing heavy minerals, especially in the heavy mineral outer circle turns to the spiral groove distillate the inner edge 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, quartz grader, due spiral chute rotation, 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 .
