Different machines to meet all needs
Electrical energy is consumed primarily in the grinding (size reduction) of the finished product before it is shipped to customers. In 1974, CRH Canada invested in a new cement mill that operates at a larger capacity with more efficient separation, significantly reducing the electrical energy requirements.
