Continuous vs. Batch Mixers

When it comes to industrial mixers, there are many viable options depending on application. Mixers can be classified into two categories; batch mixers and continuous mixers. Both have their advantages and can be used to mix concrete. Batch mixers are typically used to produce construction materials for interior and exterior projects whereas continuous mixers are applied in the food, chemical, pharmaceutical and manufacturing industries.

Batch mixers are industrial mixers used to produce precise mixtures in single batches. These are very high capacity mixers and can mix batches up to one thousand gallons. The typical batch mixer consists of a cylindrical tank with two opens. To mix raw materials, they are inserted into one end as the tank rotates. Once the materials are thoroughly mixed the mixture leaves through the opposite end into molds or troughs. Normal batch mixers are very large but they can be mounted on a wheeled frame to be more easily moved to strategic positions.

Continuous mixers mix as their name implies; continuously. They offer less flexibility than match mixers and have a chance of producing small variations to batches. However, they do require less staff to operate and are utilized when speed and efficiency is priority. To mix materials, a continuous flow of raw ingredients is fed into the machine and a flow of finished mixtures flows out the other end. This system is usually automated so there is no need to refill the mixer. Finished products out of continuous mixers are measure in grams per hour as opposed to the grams per batch measurements batch mixers utilize. Once again, both mixers have their advantages, it depends on what you priorities to determine which mixer is best suited for a particular project.
