Glass Ball Manufacturer introduced that the raw material for making glass balls can only be glass. Glass is produced industrially. The raw materials are mainly quartz sand, feldspar, calcite, Glauber's salt, etc. These ores need to be heated to more than a thousand degrees before they can react to produce molten glass.
To make glass balls, firstly, various ores are crushed and added into powder. Then, according to the composition of the glass, a batch is made, which is sent to the glass melting furnace to be melted to form molten glass. Qualified molten glass flows through the feeding tank, And flows out from the feeding port to form a strand. The temperature of the strand is generally 1150~1170°C for the medium-alkali glass ball, and 1200~1220°C for the alkali-free glass. The strand is cut into a ball after nearly 200 times per minute. The embryo passes through the chute, the ball divider, and is moved by the ball dividing plate, rolls into different funnels, and then falls into the ball groove formed by three rollers with the same rotation direction, and the ball embryo rotates on the roller. With its own surface tension, it gradually forms a smooth and round glass ball.
