Application of Screw Sand Washer:Screw Sand Washer are widely used in the distribution of ore in closed-circuit with ball mill in mining processing,in order to get a certain degree fineness of ore particles, meanwhile increasing the efficiency of grinding. Screw Sand Washer can also be used to washed sand classify ore sand and play other functions. Screw Sand Washer Advantages:1. Screw Sand Washer Sealed immersed bearing2. Powerful and independent lifting device.3. Screw Sand Washer Bolt installation ensures long life of liner plate.4. Long and narrow flume makes the material suspend a longer time in the water, which ensure best stirring effect.5. Screw Sand Washer Large submergence area could extent suspension time, which benefits the classification.6. Screw Sand Washer Appropriate drainer tank depth, area and spiral structure can best control the classifying force.7. Screw Sand Washer According to the actual needs to select single spiral and double spiral; meanwhile, there is a wide selection range of flume size.
Screw Sand Washer Working Principle Screw Sand Washer from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. Screw Sand Washer with low speed rotation stirs the slurry, so that the fine particles rice, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center Screw Sand Washer is under screw shaft, and is underneath overflow end.

Spiral Classifier-Product improvement
An automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated bringing more stable operation.
Spiral Classifier-Product Application
The overflow spiral blade is higher than overflow level, and the overflow spiral center is lower than overflow surface. The high wire spiral classifier is applied in the classification of ore with particle size 0.83-0.15mm
Spiral Classifier-Working Principle
The grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center which is under screw shaft, and is underneath overflow end.
Spiral Classifier-Product Structure
High weir spiral classifier as the ancillary equipment of grinding to pre-classifying and check classifying is also applied in de-mudding and dewatering.
Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore- dressing, and de-sliming and dehydrating in washing.
This product features simple structure, reliable working conditions and convenient operation. Because different grains have different specific gravity and sedimentation rates in liquid, this product allows the fine ore to flow in the water, while coarse ore sinks to the bottom.
