what is magnetic separation in Feldspar?

The particle size accuracy of silica sand is important. So what are the chemical treatment and inspection methods for silicon carbide micropowder? Let me introduce you to Xiaobian for details!

Chemical treatment of silicon carbide micropowder: The equipment is basically the same as the chemical treatment of 4#--240# silicon carbide abrasive. However, due to the finer particle size, the washing with water to neutral after alkali washing or pickling treatment does not allow continuous washing. Usually, after standing and clarifying, the clear liquid is drained, diluted with water, stirred evenly, and allowed to stand for clarification. This is repeated until neutral. The time to rest is 4-5 hours each time, and the water change must be 5-6 times. The purity of the silicon carbide powder thus produced is higher and the use value is further improved.

   Magnetic separation of silicon carbide micropowder: 

Silicon carbide enters the electric arc furnace---hopper---feeder---ring roller mill---rotator---cyclone---dust collector---centrifugal fan---mixing tank-- - Vibrator - Turn valve.

Silicone abrasive inspection method:

1. Pour 100g of silicon carbide abrasive sample into the top screen of the selected set of screens.

2. The screen with a large aperture is placed on the top layer, nested in turn, and must not be misplaced. The lowest layer should be a box bottom.

3. After the silicon carbide sand is poured into the stacked sieve, and then the sieve cover is covered, the stacked sieve can be sieved into the sieve machine for screening. The screening time is 5 minutes.

4. The silicon carbide is sieved and the material distribution on each inspection screen is weighed. Write down the data, and after a simple calculation, you can get the percentage of silicon carbide sand in each grade.
