Hammer milling parameters such as screen size blade selection and rotor speed can be optimized for each application depending on the equipment used The typical particle sizes that can be achieved with hammer mills is a D 50 between 150 μm and 600 μm Hammer mills tend to yield less than 25% of particles below 150 μm Because the end
Product Co Mill The infeed product is introduced into the conical screen chamber cone mill and the rotating impeller imparts a vortex flow pattern to the incoming material The material is then forced to the screen surface by centrifugal acceleration ensuring continuous delivery of powder / granules into the action zone between the screen and impeller
Figure is multiplied by the sq footage of the screen deck • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen • The vibrating screen capacity is determined • Using a standard sizing formula 9 variables • Basic capacity of each deck opening • Unique factors of that application •
Cylinder screen The cylinder screen is installed in grain receiving section of flour mill plant Its inner cylindrical screen serves to separate coarse impurities from cereals during the pre cleaning phase such as straw particle string paper pieces of wood maize stalk and cobs etc While the outer cylindrical screen can get rid of the small impurities in grains the dedusting part can
· Pulp Washing and Screening Pulping process consumes a high amount of chemicals therefore recovery of chemicals from pulp also known as pulp washing is required because first they are expensive to replace second they interfere with the downstream process and third they are harmful for the environment
