Solutions with weighing technology and control systems for concrete plant design
19 July 2019
In a concrete manufacturing plant, instrumentation integration is ideal. In Ontario, Canada, J. McCoy Equipment and Oshawa Bearing Service know this for a fact.
For more than 30 years, J. McCoy Equipment has built concrete batch plants and ready mix concrete facilities.
Oshawa Bearing provides the plant automation component, joining both electri- cal and mechanical components.
Add Siemens weighing and automation technology to the mix and the result is an ideal partnership with innovative solutions.
Concrete across the continent
Cement, water, and aggregate are the primary components for making concrete for storm drainage/retention structures, gravity pipes, precast bridges, and many other concrete items at one of J. McCoy and Oshawa Bearing’s customers.
One of their customers is on of the largest manufacturers of concrete products in North America. This company manufactures concrete pressure pipe and pre- stressed bridge girders. Their products form the backbone of roadways, high- ways, and drinking water systems.
In the concrete manufacturing process, the precision of the recipe dictates the quality of the nished product and full reporting of every batch for CSA and MTO are an absolute requirement.
Materials that are stored in multiple bins are monitored using weighing systems to accurately control each ingredient in the right amounts. Using microwave moisture sensing the Siemens PLC adjusts the target weights to compensate for the water content within the aggregates and in turn adjusts the water target in the mixture.
