Grizzly Screen is also known as a Grizzly feeder. The Grizzly feeder produced by our company is a new type of Grizzly feeder designed for conveying large materials evenly before crushing in a medium-coarse crusher. The Grizzly feeder adopts the structural characteristics of a double eccentric shaft vibrator to ensure that the equipment can bear the impact of large material falling, and the feeding capacity is large. In the production process, the block and granular materials can be evenly, regularly, and continuously given to the receiving device from the storage bin, so as to prevent the receiving device from crashing due to uneven feeding, prolonging the service life of the equipment. The feeder can be divided into a steel plate structure and a grate structure. The feeder of steel plate structure is mostly used in sand and stone production lines, and all the materials are uniformly sent into the crushing equipment. The grate structure of the feeder can perform coarse screening of the material, making the system more economical and reasonable in preparation, and has been used as essential equipment in crushing and screening.
