spiral concentrators are used in most applications, particularly for concentrating low-grade ores. Manufactured from lightweight, corrosion and abrasion-resistant materials, our spirals require minimal maintenance and upkeep. Gives you an effective and low-cost solution for gravity separation. Reduces maintenance with a durable design.

A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore.

2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30～1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.

A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …

Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.

Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the …

Thus, classifiers with a 300 mm spiral diameter revolve at about 8–20 rpm, while the 2000 mm diameter spirals rotate at about 2–5 rpm to give a sand conveying speed of 2–3.5 m/s. The raking capacity of the large classifiers is approximately 200 t/h, while smaller classifiers have raking capacities as low as 1.5 t/h.
