JAW CRUSHER

What is the primary function of a jaw crusher?

• To impart an impact on a rock particle placed between a fixed and a moving plate (jaw).

• To cool down materials and rotate material between the jaws

• To reduce the size of particles to micron and nano size

How does material move through a jaw crusher?

• It is pushed by hydraulic pressure

• It is nipped and released between plates

• It is pulled by a magnetic force

• It is melted and poured out

What are the surfaces of the plates in a jaw crusher typically made of?

• Plastic

• Glass

• Hardened steel

• Aluminum

4. What happens when the ore or rock is fed to the crusher at the maximum opening or gape?
   

• It is immediately ejected out
  

• It is crushed into smaller sizes
  

• It is magnetically separated
  

• It is cooled down

In a single toggle jaw crusher, what impact does the absence of a secondary toggle plate have on its operation?

• Decreased stability

• Increased efficiency

• Reduced crushing capacity

• Enhanced material throughput

How does the design of a double toggle jaw crusher affect its performance compared to a single toggle jaw crusher?

• Double toggle allows for greater crushing force

• Double toggle reduces energy consumption

• Double toggle minimizes wear and tear

• Double toggle enhances material feed control

What is a primary characteristic of jaw crushers

• They are expensive and delicate

• They produce fine products efficiently

• They are heavy duty and relatively cheap

• They are primarily used for secondary crushing

In what specific crushing stage are jaw crushers typically utilized?

• Primary crusher

• Secondary crusher

• Tertiary crusher
