Multi-stage pneumatic municipal solid waste separation and recovery of a plurality of classifications

摘要: Heterogeneous municipal solid waste is pneumatically separated in a first stage into relatively heavy incombustible and lighter weight combustible fractions. The light fraction further second heavier grade fuel In third still separation may be effected of the suitable for other uses such as manufacture certain building materials lightest most air suspension boiler or kiln firing. Primary shredding all to separated, final reshredding are provided attain maximum combustion efficiency. Apparatus effecting large volume continuous process multi-stage pneumatic comprises serially connected tower separators including means controlling velocity meet wide variety conditions being handled.
