Product Name: Slag Ball Content Analyzer

Product Manual:

First, the use of slag ball content analyzer:

In accordance with GB/T 5480.5-2008, this device is designed for testing the slag ball content in mineral wool and its products. It can analyze glass wool, slag wool, rock wool, aluminum silicate cotton, and related materials. With a compact design and practical functionality, it is an essential tool in laboratories.

Second, usage steps of the slag ball content analyzer:

Step 1: Sample Preparation

Follow GB/T 5480.5-2004 to select the sample, cut the full thickness of the material to about 11g. For glass wool, burn at (500±20)°C for 30 minutes. For silicate cotton, burn at (700±20)°C for 30 minutes. Remove the binder and weigh accurately to 0.01g. The number of samples should be as per the product standard, but not less than 3 samples.

Step 2: Pressing the Sample

Place the weighed sample into the corresponding sample cylinder and press manually using the press machine.

Step 3: Wetting the Sample

Take out the pressed sample and place it in a 250mL measuring cup. Add 50mL of surfactant solution and stir well to ensure the fibers are wetted and dispersed in the solution.

Step 4: Separation Test

Transfer all the sample into the separation barrel. Turn on the water flow and adjust the rotameter to 60mL/min until the fibers are fully suspended. Then increase the flow to (120–180)mL/min and continue for about 10 minutes. Once the water is clear, open the discharge valve and let the slag balls fall into the standard sieve according to the product specifications.

Step 5: Drying

Place the sieve containing the slag balls into an electric drying oven and dry at 105–110°C for at least 20 minutes.

Step 6: Sieving

Transfer the dried slag balls into the standard sieve specified by the product standard. Add 3 ceramic balls with a diameter of (20±1)mm, cover, and run the sieve machine for 15 minutes.

Step 7: Weighing

Weigh the sieved slag balls on a balance with an accuracy of 0.01g.
