Kneading with the Big Kneader

Since the cleaning of the big kneader takes about at least two hours the kneading was started early in the morning. Now it is with the same Arg. body and 8mm fibers and same as earlier the test samples had to be taken out at intervals. After 4 hours and 45 minutes, we tried to vacuum the device to make an extrusion of the kneaded material but the vacuuming seemed to be not working. Hence, the extrusion was stopped and cleaning started, it took about 3 hours to be finished.

For another project I had to give hand by doing a test on three samples. Each and every sample had to be placed in hot water of which the temperature had to be between 50⁰ - 60⁰ degrees. The beaker with water was placed on the electronic heater (electronic hotplate) and when the temperature was in equilibrium in between the mentioned temperature a sample (Tablet like) was carefully put into the middle using a tweezers. After five hours the samples had to be taken out and dried and weigh. The intention was to remove the binder which is dissoluble in water.
The weight of the first sample has reduced but it was kept to be dried more in air.
