Vibrating Grizzly Feeder. A vibrating grizzly feeder (VGF) is located at the bottom of the hopper and directly feeds into the jaw crusher. As its name would suggest, the VGF vibrates and this agitation causes the material to separate. This process, known as stratification, moves the small material to the bottom and larger to the top.
Efficiency tip. Pre-screening of the feed to remove the fines, especially in tertiary crushing, is a good practice; it helps to avoid packing of material in the chamber while maintaining an efficient, effective crushing …

1. Cost-Effective. One of the primary benefits of using a limestone crusher is its cost-effectiveness. The machine is designed to reduce the cost of production while still delivering high-quality limestone. Additionally, the machine is designed to be energy-efficient, further reducing the production cost. 2.
Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.
The term "primary crusher," by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant.
