Summary:

Ready-mix concrete is concrete that is manufactured in a batch plant, according to a set engineered mix design. Ready-mix concrete is often used over other materials due to the cost and wide range of uses in building, particularly in large projects like high rise buildings and bridges. It has a long-life span when compared to other products of a similar use, like road ways.

Solution:

In the Ready-Mix Plant Automation, a concrete mixture is prepared by using the raw materials as per the customers required set weights. Initially the valves will be open and then the required amounts of the raw materials will be dumped into the respective bins. From there the material is dumped into the Skip Bucket, the weight of the Skip bucket is weighed and the data is sent to the Controller.

Simultaneously water, Ad-mixer and Cement are also weighed and the data is sent to the PLC. From there the whole materials are dumped to the mixer. Whenever the weights of the materials are matched with the set value automatically the valves will be closed and the mixing operation starts. To sense the material weight Load Cell has been used.

PLC and SCADA used to make different recipes, thus Operator can select required recipes and run the system. The system mixed all materials automatically based on recipe loaded. Ex.: Cement, Ad-mixer, sand and aggregate. Automatically valves open and close after filling required amount.
