Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an intermittent concrete mixer. Background Art

[0002] Intermittent concrete mixer is a widely used mixing equipment, mainly used in the production of concrete. Intermittent concrete mixer is a mixer that mixes in a specific period of time. When the mixing is completed, it needs to stop operating for the next step. This mixer is more suitable for small batch, high-precision mixing production processes.

The utility model can make the mixing barrel and the mixing mechanism rotate simultaneously in opposite directions. Compared with the existing method of mixing materials with a single mixing mechanism, this method has higher mixing efficiency, can further reduce the time required for mixing, and save production costs.
