The kinds and test run of concrete mixer

Double-horizontal-shafts forced type concrete mixer. Virtues: high mixing performance, high efficiency, good adaptability, high reliability. This one is especially applicable for concrete batching plant.
Disadvantages: The price offered is little high. the devices are mainly good for medium- and large-scale commercial cement batching plant. This may not be appropriate for small concrete mixing plant.
Single horizontal-axis forced concrete mixer. Virtues: mixing performance is nice. The production efficiency can meet the small cement batching plant needs. Such as mobile cement plant, it is featured by compact structure, small floor coverage, simple installation and high degree of automation. Lower price. Disadvantage: weaker adaptability. That is typically not suitable for use in medium- and large-scale commercial concrete mixing plant.

The no-load test run of concrete mixer:
1. Start up the concrete mixer, the rotating direction of belt pulley should be consistent with the label direction. If direction is wrong, timely change the power supply wiring;
2. Boot volume field motor to lift hopper to see whether the hopper is reliable during the lifting process.
3. Operate the discharging door and make sure the opening and closing of discharging door are correct;
4. Move the pump motor to check whether the rotating direction is right.
