LL Spiral Chute

LL Spiral Chute

Spiral chute is a combination of the spiral separator centrifugal separator, spiral chute and shaking table, the characteristics of the equipment, is the best equipment for mining, mineral processing, especially the beach, river, sand beach, the stream of placer mining is more ideal.

Advantages

Spiral chute has reasonable structure, simple installation, covers an area of less, easy to operate, stable ore dressing, points clear, large quantity and high efficient separation enrichment ratio, high recovery rate, the characteristics of reliable operation. Have weight light, moisture, rust, corrosion, to feed quantity and concentration, particle size, grade of strong adaptability, no noise, etc.

Spiral chute has the domestic advanced level of efficient re-election new equipment. Used for separating particle size 0.3 0.02 mm of fine grained iron, tin, tungsten, tantalum, niobium, gold, coal, monazite, rutile and zircon as well as with sufficient proportion difference of other metals, non-metallic minerals, the metallurgical department organize relevant scientific research, design, colleges and universities, and factories and mines etc through the verification, thinks that the equipment performance is good, indicators advanced, can be used widely to determine the batch production.

Features

  • 1. The main process parameters for influencing spiral groove choose other ore volume flow rate and give the solubility. Supervision by stable feed volume than the feed concentration of stability is more important. Practice has proved that as long as give constant volume flow rate, feed concentration within a certain range workers fluctuation little influence on the sorting result.
  • 2. Spiral chute process stable, easy to control. Feed volume per head for LL - 900-1.2-1.8 cubic meters per hour, LL - 1200 per head of 2.5 to 3.5 cubic meters per hour. Volume size can change the distribution characteristics of mineral along the spiral groove width to main control stability, allowing range should be less than + / - 5%, generally USES the constant pressure to mine.
  • 3. Allows feed concentration range is larger, the general is 30% ~ 60% should be determined through experiments. Roughing feed concentration generally in 30% ~ 50%, selection of feed concentration could be selected within the scope of 40% ~ 60%. Similar effect, high concentrations to choose advisable, in order to improve the capacity of equipment.

Notes:1. The above technical parameters calculated based on max spiral quantity and max pitch. Specific data is subject to actual machine. 2. The feed concentration (percentage) is not absolute amount. 3. Spiral chute is different from screw pitch and the total height of corresponding spiral chute is also different.
