Crushing and screening equipment is used for separating and breaking down rocks into usable aggregate materials. Crushers are used to break apart mined rock and recycled concrete so it can be used in construction and agricultural projects. The following are some common terms used to describe crushing and screening equipment and processes.
Aggregate – Aggregates are materials like gravel, crushed rock, recycled concrete, and sand that are used in construction. They are essential for the making of concrete, used in drainage systems, and used in foundations. Aggregates are often mined in quarries.
Crushed Stone – Crushed stone is a type of aggregate that is made from mined rocks, which are broken down into small pieces using a machine called a crusher. It has many uses including being used to make concrete, roads, and pathways.
Mulch – Mulch is used in gardening and agriculture as a protective cover for soil and a nutrient source for plants. Crushed stone, woodchips, bark, and hay are all popular types of mulch. They keep soil warm in cool climates, allow for water retention, prevent soil erosion, and stop weeds from growing near plants.
Rock Screen – Rock screening equipment is used to separate soil and aggregate materials by size. Screening equipment can also be used to remove debris from construction materials. Screens are often used to separate large rocks, which can then be broken down by crushers.
Ore – Rock that contains minerals or metals is called ore. Ore is obtained through mining and then the valuable metals or minerals are extracted. Metal ores include iron, copper, and gold ore.

The average person may not be aware of exactly what crushing and screening equipment is used for. However, most every time that rock or concrete is used for outdoor projects, chances are crushing and screening equipment was at work. This type of equipment, processes the aggregate from mining or other sources, into gravel or concrete for use. The machines are also used for a variety of recycling projects, creating new material that can be used for a wide range of purposes. Crushing and screening is also used in industrial and mining venues, creating all types of construction material that can be used, directly from the conveyor track, in the industrial world. Various equipment that crushes is used for different materials. It is also used with machines big enough to process even the hardest materials into useable form and conveyors to take the aggregate from one area to another.
With a variety of equipment, the crushing and screening process begins with a primary crusher that feeds large boulders through to a machine that vibrates the aggregate for the first crushing. Next, a belt conveyor takes the concrete or rock into a secondary crusher, which is then transferred to a vibrating scalping screen for additional impact. Any gravel that comes out on the track, in a suitable size, will be taken by dump truck to a final point. While the rest of the aggregate is crushed again. Other types of equipment might also be used, such as a ball mill, cone crusher and roller crushing machines. A wide range of industrial equipment, concrete, stone and other materials can be effectively crushed and transformed into entirely new and useful materials.
