We produce the Grizzly King Jaw Crusher to be more durable and efficient versus similar crushers on the market. A heavy and rigid construction reduces frame flexing which can lead to cracking and costly repairs. The Grizzly King’s long jaws outproduce the competition, reducing recirculation, thereby taking a load off of other equipment in the crushing circuit.

What You Need to Know About Jaw Crushers

Jaw crushers are typically used for hard rock crushing applications including: 

  • Primary crushing at mines 
  • Sand and gravel production 
  • Round rock crushing 
  • limestone crushing
  • Recycling applications

Jaw crushers are used in recycling applications because they’re a “bulletproof” piece of aggregate equipment and are less susceptible to damage compared to impact crushers or cone crushers.

Jaw crushers typically have a 10:1 reduction ratio. This means if there is a 30″ opening, there is typically a 3″ closed side setting.

Sepro crushers have a 1.5″ stroke at both the pitman (top of the jaw) and toggle plate (bottom of the jaw).

While some competitors have upgraded to a 1.5″ stroke, many still use a 1.25″ or 1″ stoke such as Telsmith and Terex Pegson.

A rock crusher with a 1.5″ stroke will have 20% improved production compared to a crusher with a 1.25″ stroke, and an even greater improvement compared to a crusher with a 1″ stroke. Each cycle of the jaw will produce a greater reduction in particle size.

Sepro’s Grizzly King Jaw Crusher has a longer jaw and deeper crushing chamber than most competitors. This makes it more aggressive at grabbing the material and means each rock gets more cycles in the crushing chamber. This creates a better product gradation, resulting in a higher throughput of finished material. 

Sepro’s 42×48 jaw crusher is one of the best jaw crushers in the industry for crushing chamber depth.
