Abstract: PURPOSE: To make an entire apparatus compact and to improve sorting accuracy by a method in which a refuse bag is broken by a bag breaker while the bag is transported by an oscillation conveyer, and refuse removed from the bag is sorted into light combustibles and heavy non-combustibles by a pneumatic separator. CONSTITUTION: A refuse bag fed into a hopper is sent to an oscillation conveyer and transported by the oscillation to a refuse discharge opening. During the transportation, the upper blade 22 of a bag breaker is turned downward from above to stab the bag, and the upper blade 22 is moved in the transportation direction to collaborate with a lower blade 21 to break the bag. As a result, refuse removed from the bag is disintegrated in front of a refuse discharge opening by an air current jetted from a through hole 51 above a transportation passage 12. The discharged refuse is sorted by an air current jetted from the jet part 42 of a pneumatic separator 4, and light combustibles are blown off into a combustible storage part 49, while heavy non-combustibles are received in a non combustible storage part 47 which is located nearer.

Title: Calcium aluminate hydrate and production thereof
Inventor: WATANABE SUSUMU
IPC: C01F7/16
Filed: 1989-12-18
Abstract: PURPOSE:To obtain calcium aluminate hydrate having improved surface characteristics by a simple method by subjecting lime and aluminum hydroxide to hydrothermal reaction in a specific ratio. CONSTITUTION:In producing calcium aluminate consisting essentially of 3CaO.Al2O3.6H2O by hydrothermal reaction of lime and aluminum hydroxide, lime and aluminum hydroxide are used in a ratio of CaO/Al2O3 (molar ratio) of 0.1/1-2.5/1 to give calcium aluminate hydrate having a beohmite coated layer. In the production, hydrothermal reaction is carried out by using excess aluminum hydroxide based on lime in comparison with existing method. When the molar ratio is <0.1/1, content of water of crystallization is reduced and unfavorably flame retardance is reduced. On the other hand, when the molar ratio >2.5/1, the beohmite coated layer is lessened and unfavorably improving effects of surface characteristics is diminished.
