The invention discloses a
production line and technology for preparing
calcium aluminate powder through white mud. The technology includes the steps that 0.4-0.5 part by weight of white mud
slag /
carbide slag, 0.9-1.1 parts by weight of an aluminous
raw material and 0.04-0.05 part by weight of
crystal nuclein are sequentially conveyed in a stirring
machine and mixed and stirred to be even; the mixture is conveyed into a
rotary kiln and calcined for 20 min to 40 min till the temperature of the mixture is 900 DEG C to 1,100 DEG C; after calcining is ended, the temperature of the mixture is cooledto 300 DEG C to 400 DEG C through a cooling
machine; after cooling is ended, the mixture is powdered through a first
ball mill, and
calcium aluminate powder is prepared. By means of the
production line and technology, white mud can be eliminated, the local graceful natural-
ecology human settlement environment is powerfully protected, the recycling speed of renewable resources is increased, the effects of turning waste into wealth and turning harm into good are achieved,
pollution is governed, the environment is improved, occupied
land resources are released, the beautiful environment can be created for persons, and the harmony and unity
ecological environment between man and nature is promoted.
