Spiral Classifier |
| |
| Spiral Classifiers Introduction: |
We produce high weir type, single and double spiral, and immersed single and double spiral classifiers. 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. This classifier can filter materials and send coarse materials to the feeding mouth and discharge fine materials from the pipe. The seat of the machine features channel steel material, while the body is armor plated and the spiral axle is made of cast iron for durability. The machine's lifting equipment can be used manually or electronically.
There are four different types of the classifiers: high weir single spiral, high-weir twin spiral. sunken single spiral and sunmen twin spiral. while the single classifier has two versions, traditional and advanced. For the update model, an automatic lifting device is equipped at sand feedback end, which sends the sand discharged to the bottom of the tank to a proper position of the tank wall for discharging, to fit with the ball mill without scoop. Taking away the scoop from the mill feeder. 1-1.5 kwh of energy could be saved, and meanwhile, frequent miantenance of the scoop is avoided and wearing of the big and small gears is reduced. Furthermore, owing to smooth running of the mill, operating efficiency is improved, resulting in power save as well without the scoop facility, the performance of the classifier and milling capacity are not effected. |
