subject: Analyzing The Characteristics Of The Classifier [print this page] The spiral classifier is composed of a U trough, spiral, transmission, elevator machine, support bearing etc. The downflow weir of the high weir type is higher than the lower bearing, but lower than the upper edge of the lower spiral. There is a horizontal long axis with helical blades in the U trough, and a downflow weir designed in the lower place. The transmission is installed in the upper chute, the upper main spiral shaft supports the bearing on the drive frame, while the lower bearing is fixed at the level of the elevator. The elevator is able to make the lower part of the spiral ascend and descend to regulate the distance between the spiral and the bottom of the chute as well as the confirming size of the spiral. Meanwhile, the spiral should be raised up at the time of a stop in order to avoid the desilting burying the spiral that will impinge on starting. The bearings of the main spiral shaft are quite vital parts, due to relatively harsh working conditions, the requirements for the sealing of the bearings are high. At the same time, the operator must strengthen the maintenance.
The spiral separator is one of the numerous water conservancy classification equipments, a kind of mechanical classifier with the structure of elevating and conveying desilting. According to the spiral numbers, it can be divided into two types, one is single-spiral classifier, and the other is double spiral classifier. According to the height of the downflow weir, it can be further sorted into high weir type, low weir type as well as immersed weir type. As for the specification of the spiral separator, it can be presented by its spiral number and the spiral.
The biggest advantage of duplex flow classifier is unparalleled economic indicators. Combination of high grade efficiency, large capacity, low footprint and advanced technology of multiple hierarchical, reduces construction investment and running costs to a large extent. Since above statement of low wear, low power consumption, it leads to compound fluidized classifiers lower investment. And the running cost is significantly far lower than other devices, which is also one of the biggest advantages.
Henan Hongxing is a professional magnetic separator manufacturer. It has produced a set of Allflux dual fluidized classifiers began to put into use in the world famous Zhengzhou Hongxing Company at main mineral processing plant in July 2002. It replaced the original 2 series of grading equipment, and selected fine magnetite ore, which was a great success. The device model is AFX-1 500. Ore handling capacity is 280 Uh, ore density is 4 500 kg/m ', and slurry density is l370 kg/m3. The pulp concentration is 35%. The largest feeding ore particle size is 850 um, P is 140 F.cm,-44 UM takes account 20%--35%. The magnetic system of dry type magnetic separator adopts high quality ferrite or using the composite material by rare earth and magnetic steel. The average magnetic induction strength of tube surface is 100-600mT. According to the requirements of users, we can offer downstream, semi-countercurrent and countercurrent and other types of magnetic separators.
