Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Crusher Run: Prices, Uses & Benefits Crushed Stone, Sand

This is probably because the concrete was poured directly onto the dirt below. As the ground shifts and settles, the concrete looses its structural integrity. Applying a layer of crusher run atop the soil will help the concrete to remain in place and last much longer.

Basic steps to compressor unit calculation and selection

Air mass to be transferred by compressor is constant depending directly on compressor design specifics. However, it is common practice to identify capacity with volumetric and not mass values. This often leads to failure in calculations and as a result to errors in manufacturing calculation. This is due to air to be compressed like all gases.

Thermal expansion Wikipedia

Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves.
