Environmental Benefits of Slag Cement. Slag cement is used in nearly all types of concrete construction: pavements; structures and foundations; mass concrete (i.e., dams and retaining walls); and prestressed, dry cast and precast concrete products such as pipes, pavers, and blocks. Today, slag cement is the best option for a concrete producer to use …

Wilczek: The mill accepts a maximum particle size of about 0.5 mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 10-20 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.
