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 configuration rolling wheel sand mixer device has a certain weight, when both wheels rolling sand around Mixer spindle revolution, but also around the rolling wheel rotation. Rolling wheel rolling sand sand while rubbing research equipment manufacturers, so that the sand particles covered with a thin film layer of bonding agents. When the noodle mixture of sand and core sand, sand quality is better than the other mixer. By the early 1950s had a spring-loaded roller wheel Mixer. As a result of spring pressure, 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. Sand grind a safe operation, before the work carefully to confirm Nianzishan is intact, if the fault promptly notify the service for repairs. 2. Work Wear good labor protective equipment. 3, before boot sand grind before turning to check the compliance of gear parts, bearing anchor bolts and screws to be tightened to connect the various parts of the reliable, identify problems and timely treatment. 4, electrical switches and power is in compliance with the requirements found in time to find out the gates or open an electrician for replacement and maintenance. 5, in line with the first boot, the principle of the use of clay filler sand mixer equipment suppliers, not too much filler, overloaded. 6, pay attention to the motor, the functioning of each bearing reducer, such as abnormal immediately stop check processing. 7, the size of the gear every day grind sand sand equipment manufacturers, plus the 2nd calcium base oil once. 8, each time you want to run out of clean sand grind, grind sand banned from entering the interior clean and maintain clean equipment and the environment. 9, in the cleaning process must supply the total gate shut clay sand mixer equipment, Qingdao Heng (certified), Shandong Mixer equipment provided by Heng Machinery Co., Ltd.
