There are grates made of cast or sheet metal as screen panel on the top deck where material is fed. The pieces passing through the distance between these grates pass to the lower screen panel. In the lower decks, perforated sheet metal or steel mesh screen is used as a screen panel. This type of screen is generally used to quickly bypass the fine material between two crushing stages. Heavy-duty materials should be used, as they will be involved in the classification of very coarse materials. When coarse-grained material needs to be classified, grizzly screens are the first choice. The fact that the first screening panel that meets the coarse material consists of cast or sheet metal grates is very beneficial in terms of reducing spare parts consumption. It prevents timeless stops and shows high performance in terms of efficiency. In the primary stage, the materials which are placed between the rock feeder and the crusher or between the primary crusher and the secondary crusher are separated and screened. Due to the coarseness of the fed material, the wire mesh screen cannot withstand working at these stages and must be replaced in a short time. Grizzly screens are the most suitable screen type for these stages.
