Sand Mixing, Foundry Machinery

Foundry sand is used in creating cores and molds used in the casting of iron, steel, copper and aluminum products including girders, copper pipes and aluminum supports. Foundry sand is the second largest industrial use of.

The process of foundry sand mixing is often called mulling. The process involves mixing of sand, water and binding ingredients to form tempered ready-to-use molding or core sand. Foundry sand mixer is rather simple equipment with a cylindrical container and mixing blade. The cylinder is usually vertical type.

It needs an operator to monitor the process all the time even though the process may be fully automated. First the material is weighed and passed on to the machine hopper. Other materials like core oil and water is automatically weighed and let in. The blades churn for the set duration.
