The Advantages And Disadvantages Of Spiral Classifier - China

price: contact company for price

Spiral classifier is a common material grading equipment, mainly it is

suitable for the sand, we know that in the process of making sand need

spiral classifier, it is based on the material and water mixture to

grinding, finally through the classification, in the fine particle

materials above will overflow, materials and large particles will be

deposited, the particles of the material will be screw up to the inlet

regrinding, following a brief introduction of the advantages and

disadvantages of spiral classifier, and how to improve the

classification efficiency of spiral classifier.

Advantage: the spiral classifier can be used as a paint powder separation, can be very well control the concentration of material in sand, to meet customer demand; Spiral classifier is suitable for various large and medium- sized system of sand production line, the stone powder content can be adjusted through the equipment; Easy to control, the quality of the powder fineness adjustment is also very convenient, more flexible and reliable, equipment service life is long, don’t need how to maintenance, high efficiency; Equipment is controlled by frequency conversion control technology, the operation is very simple.

The disadvantage of spiral classifier , such as classification efficiency is low, fine grained material overflow concentration is low, for junior job is difficult, this is a big shortcoming; Spiral classifier is generally suitable for coarse classification, namely the overflow particle size greater than 0.15 mm, the overflow out easily. Relative to faults is less, it is a kind of equipment is good.

How to improve the classification efficiency of spiral classifier? 1, change the traditional way of line of mine, we can use the double side ore manner, bilateral row ore words shorten the classifier of ore grain movement in the road, so that will be fine grained materials in time, greatly shorten the time of the settlement; 2, it has been on the subsidence in the bottom of the fine ores, a stirring device should be installed under the equipment, so that you can restore the fine material float, and overflow, so you can improve efficiency. 3, we can consider to change the gravity sedimentation classification in staging area, so you can add new fields, for example, on the top of classifier can increase a cylinder screen, so that it can be secondary classification, so as to improve the working efficiency of the classifier improve the classification efficiency of spiral classifier, it is to better the materials are better separation of different particles.
