Brief History of Crushers

Stone crushers have played a significant role in America since its creation in the 1800’s. The first crusher built relied heavily on steam hammer technology. A decade later, an impact crusher with a wooden drum, box, and an iron hammer fastened to it was issued a US patent. Although both creators never marketed their inventions, it was the start of crushers.

Since then, crushing stone for repurposing and building has been in existence. However, Eli Whitney developed and sold the first crusher in 1858; it was known as Blake Jaw Crusher. Blake came up with this equipment by integrating a critical mechanical principle, the toggle linkage, to put down a rock surface on the roads of Westville town. 

He was inspired while serving on the New Haven town committee and got involved in road construction. Today, this pioneer crusher is the standard for all jaw crushers.

Types Of Crusher Machines

There are various types of stone crushers. Each is different in crushing application depending on the material to be destroyed, the desired product size, the feed size, and the crusher’s capacity. Still, below are some common types of crusher machines.

Primary Crushers

These are the pieces of equipment that carry out the first level of crushing. Materials brought directly from the blasted construction are fed into these crushers. Some common ones include,

  • Gyratory Crushers
  • Feeder-Breakers
  • Jaw crushers
  • Sizer crushers

Secondary Crushers

Materials that have gone through the first crushing stage are fed into the secondary crusher to be reduced further. The second crushing stage is crucial in the quarrying industry. Standard well-utilized secondary crushers are,

  • Impact crushers
  • Hammermills
  • Roll Crushers
  • Cone Crushers

Tertiary Crushers

Tertiary crushing is more utilized in the mineral processing industry, but as the name implies, it involves further crushing after secondary crushing to result in smaller materials. Some tools used during the process include,

  • Conveyors
  • Screening Equipment

Advantages And Disadvantages Of Different Types Of Crusher Machines

  • High productivity.
  • Less vibration.
  • It produces even sized particles.
  • A higher crushing ratio.

Cons

  • Heavy and inconvenient to move around.
  • It has a complex structure and isn’t as easy to configure.
  • Equipment maintenance incurs higher costs.

Impact Crushers

Pros

  • It has a simple structure.
  • A higher crushing ratio.
  • Convenient equipment operation and maintenance.
  • High productivity.

Cons

  • The operation unit is noisy.
  • It is unable to produce particles with completely even sizes.

Hammer Crushers

Pros

  • High productivity.
  • A higher crushing ratio.
  • Low power consumption.
  • It has a simple structure.
  • Its products are even sizes.

Cons

  • Materials may clog equipment screens.
  • It causes excessive wear due to fine grinding of hard and abrasive material.
  • It takes longer to examine and repair.

Final Thoughts

There are different types of crusher plants, but those listed above are common ones used in crushing stones, minerals, and other solid materials.
