We Can Take Some Means to Solve Failures About Spiral Separator

Spiral separator is widely used in the processing plant in closed circuits with ball dubbed sub-process diversion mineral sands, or in a gravity concentrator in the spiral classifier to grade ore and fine clay, and metal beneficiation process for particles of slurry grading, washing and de-mining operations in the mud, dehydration and other operations. The machine has a simple structure, reliable, easy to operate.

The possoble failures and solutions of spiral separator are as follows: Overload of abnormal vibration and noise, which is maybe caused by the following reasons: The large amount of sand return of loose leaf ; Slot into hard sundries etc.; Each bearing lubrication bad or damage to the machine frame is loose or skewed ; Screw spindle bend or break. You can deal with them by the following methods: 1. Adjust the 2. Tighten or replace 3. Parking clean up 4. Strengthen the lubrication or replace 5. Tighten or adjust the 6. Reinforcing repair or replacement. And Bearing temperature is too high, speed reduction box fever, which is maybe caused by the following reasons: 1. The shortage of oil or oily bad 2. 3. The bearing clearance is wrong or damage to the bearings are skewed 4. Under the belt too tight 5. Gear backlash is too small or too large. You can deal with them by the following methods: (1) gas or oil change (2) adjust or replace 3. Reassemble 4. 5. Adjustment repair or replacement

And classifier is a gravity based concentrating device, that separates light density granular and sandy (10 mesh to 200 mesh (2 mm to 0.075 mm)) consistency material from heavier density material. In order to have a good separation, there should be a difference in SG”s of at least 1.0. One main benefit of spiral concentrators is they have no moving parts. The feed range, in percent solids, to a spiral ranges from 20% solids up to 40% solids. Depending upon the material characteristics, a maximum efficiency will usually be reached somewhere in this range. All that is...
