Roller type sand mixer is mainly used for mixing sand and core sand in foundry. And widely used in ceramics, refractories, cement, brick making and other industries to mix various materials.
Appeared at the beginning of the 20th century, it is still widely used in the mixing of core sand with clay as the binder. This sand mixer is equipped with a roller with a certain weight. When the sand is mixed, the roller can both revolve around the main shaft of the sand mixer and can rotate around the axis of the roller. The roller grinds the molding sand while rolling, so that the molding sand particles are covered with a layer of adhesive film. When mixing surface sand and core sand, the quality of sand mixing is better than other sand mixing machines. In the early 1950s, there were roller-type sand mixers with spring pressure. Due to the use of spring pressure, the weight of the roller is reduced, and a higher spindle speed can be used. At the same time, the roller pressure can be automatically adjusted with the thickness of the sand layer being rolled, thereby ensuring a uniform sand mixing effect and improving the sand mixing efficiency.
The specific models can be divided into:
S1110 double-roller sand mixer; S111A single-roller sand mixer;
S112 double-roller sand mixer; S114C double-roller sand mixer; S118 double-roller sand mixer
