The Working Principle of Sand Making Equipments

The chute feeder can be installed on the ground or onto discharge port of ore bin.The chute bottom plates do the reciprocating movement, the movement frequency is 20-60 times/min and the stroke is 20-200mm. Stroke can be adjusted by the eccentric wheel; the eccentric throw is half of the stroke. According to experience of some mine sites, the eccentric throw should no less than 30mm for cohesive ore. The chute width is 2-2.5 times of maximum feeding granularity. The biggest chute feeder can supply ore with granularity less than 500mm. The most common specification is 980*1240 chute feeder, with feeding granularity between 350-0mm, which is the best partner of 400*600 Jaw crusher .Chute feeder, also known as reciprocating or oscillating feeder machine , it is the storage mine shafts nesting feeding equipment that applicated in the earlier times . Its types are various,the common features of these types are the material layer height adjustment ram; an input chute feeding plate is equipped at the underpart of the feeding chute . Its different point is the feed plate angle, the general type is the certain inclined angle (less than the static angle of repose of the material) . The feed board action is pided into Reciprocating, jitter and swing and the other types ,the transmission mechanism are crank rotary.It differs from the conventional screens with breaking of the surface tension of slurry and small granularity’s high speed vibration on sieve cover and accelerates the separating of large-density useful mines and increase the contacting probability of the materials smaller than output granularity and the sieve pore. Therefore produce good condition and make the materials smaller than the output granularity, especially the big-density materials and slurry get through the sieve pore together.Application of high frequency screen:The High frequency screen is widely used in mineral processing, coal, chemical industry, brick making, food, pharmaceutical, alkali,...
