Crushing Plants

Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.

Crushing Plants

Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.

Volume of grout| Concrete Construction Magazine

There's no sand or gravel in the grout. What will the volume be? You can calculate the volume if you know the specific gravity of the cement. Specific gravity is the weight of the cement divided by the weight of an equal volume of water. If you're using portland cement, 1 cubic foot loose volume weights 94 pounds and has a specific gravity of 3.15.

Concrete mixer

A concrete mixer (often colloquially called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete.A typical concrete mixer uses a revolving drum to mix the components.
