Salmo River Valley Historical Mining Exhibit JAW CRUSHER site #6 A jaw crusher essentially crushes large rocks to a more usable size. They’re typically the first-line machinery used in the material reduction for several applications. This includes rock quarries, sand and gravel, construction aggregates, metallurgy, and chemical industries. In industrial and mining production ,jaw crusher is the most commonly used primary crushing equipment. Jaw crusher is mainly composed of a fixed jaw plate, movable jaw plate, frame, upper and lower guard plates, adjusting the seat, movable jaw rod, etc. Knowledge of the internal structure helps to understand how it works.

Salmo River Valley Historical Mining Exhibit BLOWER site #4 Blowers operate like a large vacuum cleaner, using airflow through pipes to move dirt from the face of the drive to the surface. Blowers were a radically new technology in mining. They performed many functions – moving dirt along drives to the shaft, lifting dirt to the surface, separating fine clay particles from the dirt, and ventilating the drives – which had previously been done by other machines. Blowers could be set up more quickly and move much greater quantities of dirt compared with other mining machinery. Unlike many previous inventions, blowers were not adopted by all miners. They used huge amounts of fuel and demanded considerable mechanical skill to operate them efficiently. NEXT
