How to determine the most appropriate Sand Mixer time? It can be used in the production process, in accordance with the provisions of a sand mill, mixed sand, sand to finish mixed sample to measure its wet compressive strength. And then extend the time DRUM sand mixer of 0.5 ~ 1 min (rotor type sand mill to extend from 10 to 20 seconds). When you add a small amount of water sand to keep the sand compaction rate unchanged, again measured sand wet compressive strength, intensity values ??will have different degrees of increase. So each time and continue to extend the sand strength is measured. Intensity rise gradually towards detente, sand equipment manufacturers, until intensity no longer rising, which reached the "peak intensity" so far. Due to the proximity of the increased strength of the plateau region is extremely slow, usually considered sand strength reaches a peak about 80 to 90% of the production is the most suitable strength. To achieve the most suitable time should be the strength of the sand, mixed sand right time this type of plant can process accordingly corrected time requirements sand clay sand clay binder is configurable (core) sand. Sand realization process of mechanization is an important part of casting production. The quality of the core sand preparation directly affects the raise and lower the cost of casting production quality and yield; the sand complex process, clay sand handling and transportation of the workload is very large, and the environment is very harsh, sand equipment, so that Sand the process of mechanization is an important part of casting production. The main task of sand and Industry is to provide qualified and Industry for molding and core sand and core sand rolling wheel mixer in the early 20th century, is still widely used as a binder in clay type (core) sand mixed system. This configuration Mixer rolling wheel has a certain weight, rolling wheel around both spindle revolution mixer when sand, but also around the roller shaft rotation. Rolling wheel rolling sand while rubbing research, making sand particles covered with a thin film bonding agents. When the noodle mixture of sand and core sand, sand quality is better than the other mixer. In the early 1950s there were spring-loaded roller wheel Mixer. As a result of the spring pressure, sand production equipment business, rolling wheel to reduce weight, sand equipment production, higher spindle speeds available, while rolling pressure can be automatically adjusted with the rolling sand thickness to ensure uniform sand effect , and increases the efficiency of sand.
