Sand is a widely used in the foundry industry sand processing equipment, Mixer by sand process characteristics, can be divided into: the rolling action-oriented research ﹑ rubbing rolling wheel Mixer; mixed effect based blade mixer; rub both research ﹑ counterflow mixing or said rotor type mixer and mixing both ﹑ rolling pendulum wheel Mixer. Mixer according to the nature of work can be divided into two kinds of intermittent and continuous mixer. Rolling wheel Mixer appeared in the early 20th century, is still widely used as a bonding agent to the clay type (core) sand mixed system. This mixer configuration rolling wheels rolling wheels with a certain weight Mixer prices, rolling wheel spindle mixer around both male runner grind sand mixer when sand, but also around the rolling wheel rotation. Rolling wheel rolling sand while rubbing research, make sand particles covered with a thin film layer of bonding agents. When the noodle mixture of sand and core sand s11 Series Mixer, Mixer Mixer quality is better than the other. By the early 1950s had a spring-loaded roller wheel Mixer. As a result of the pressure spring mixer, rolling wheels reduce weight, higher spindle speeds available, while rolling pressure can be automatically adjusted to be rolling with the thickness of the sand layer, thus ensuring uniform sand effect, improving the efficiency of sand .
