FACTS

Cement Mill

A cement mill or plant is the facility where cement is produced. This is the fine powdered product that is used in producing concrete. People often confuse cement with concrete, when cement is actually an ingredient in concrete. Cement is produced by taking natural aggregates such as limestone, combining them with other elements at temperatures above 3000 degrees. The cement mill is often located adjacent to a quarry where the raw materials are mined and extracted. After the cement is produced it is usually shipped from the plant in tanker trucks or railroad cars.

Quarry or sand and gravel operation

These facilities mine and extract aggregates (rocks and sand) for use in concrete, asphalt, other construction materials, or simply for use on their own. A quarry is an operation where aggregates must be extracted from the ground via an explosion or other powerful means of breaking the rock loose from the ground. Once large pieces are broken loose, they are crushed into smaller pieces that are sorted by size, and then sold by the ton. Sand and gravel are typically found near riverbeds or water sources. The materials are dredged or excavated from the ground, processed over screens, sorted into various sizes and sold by the ton.

Concrete batch plant

Concrete batch plants combine cement, water, sand and rocks together to create concrete. These plants employ rotating drum trucks where the raw materials are combined and mixed enroute to a delivery address. Ready-mix concrete is typically sold in volume by the cubic yard.
