Industrial shredders for production of alternative fuel
Satrind has recently supplied a solution suitable to handle industrial waste (such as drums, bins, contaminated rags, oil filters) to produce alternative fuel for a cement kiln. The customer is a large Turkish company, specialised in waste collection and treatment, that has entered in a joint-venture agreement with a Turkish cement company, which produces alternative fuel from waste.
To satisfy the final customer’s requirements the plant must guarantee the required output material size to be burned into the kiln.
The plant has a capacity of 6tph and is composed by a primary shredding stage with 2R20/220, Satrind’s two-shaft shredder, and by a secondary shredding stage with 3R15/320, Satrind’s three-shaft shredder with selection screen.
The material to be treated is loaded by a crane into the feeding hopper of the first shredder fitted with an hydraulic ram to press the material on the blades. The output material falls into a screw conveyor designed to separate the liquid from the solid.
Solid material is then discharged onto a conveyor belt with a magnetic separator to extract the metal parts. Next, the waste is processed by the 3R15/320 three-shaft shredder with selection screen to obtain uniform output material size (40mm x 40mm).
Another screw conveyor and conveyor belt with magnetic separator are positioned after the second shredder and can discharge directly into a pit. The shredded material is transported from the pit to a storage centre by a conveyor belt where the material, is stocked ready to be burned as alternative fuel into the kilns.
