There are two types of concrete batching plants, the dry batching plant and wet concrete batching plant. Looking from the name, the difference between dry mix concrete batching plant and wet mix concrete batching plant is about weather there are water in the mixture, but in fact, there are other differences.
 
Dry concrete batching plants, also known as dry mix concrete batching plants, it has sand, gravel, and cement feeding to batching plant that pass the numerical or manual scale. Then all the raw materials are discharged into a chute into the truck. At the same time, the water is weighed or volume metered and discharged into the mixer truck through the same charging tank. At last, all the material mixed for 70 to 100 laps and transported to the site. Wet concrete batch plant for sale use a concrete mixer with mixing all of the above-mentioned components (including water) in a central location, the concrete is stirring on the way to the site to prevent the setting (using agitors or pre-mixed cars).
 
Dry mixing is different from wet mixing equipment. A wet mix containing a central concrete mixer while dry mix can provide a more consistent mixture in a shorter period of time (typically 5 minutes or less). Dry batching plant will usually see more variations in standard deviation of breaking strength and changes from load to load, because while mixing, the cement . stone and other mixture can be mixed more uniform than the wet type. What’s more, the mixture can be stored for a long period. Some concrete batching plants combine dry mix and wet mix characteristics to increase the application or seasonality. Both dry and wet concrete batching plant equipment can be computer-assisted controlled.
