National patent - subtraction measurement, has four advantages:

Accuracy increased by 20 times: The subtractive metering system is adopted. Since the belt is drawn at a constant speed and there is no drop difference when blanking, the weight accuracy of aggregate is improved by 20 times and controlled within ±0.1%.

Ingredients faster: sand under the uniform material at the same time, the impact on the motor is very small, in the aggregate to form a layer of sand on the flat belt a stone layer of mixed state, through the flat belt to oblique dumping belt and belt to the ChuDou ChuDou in dumping, to host three times after feeding sand has been mixed, can shorten the mixing time. It also protects the main engine to extend its life.

Sand does not arch, reduce manual intervention: the sand by the belt strong pull material, even if the humidity is very high will not arch block material, there is no need to send people with iron bars to knock or hopper, there is no need to install a vibrator, which not only for us to improve efficiency, but also reduce the noise.

Small impact rate, more energy saving: subtraction metering blanking uniform, no impact on the flat belt, no sprinkling, no impact power loss.
