B, the above-mentioned weight ratio of foundation, by descending order, respectively three kinds of raw materials are transported in ball mill and are ground and batch mixing, and then select powder by centrifugal selection by winnowing powder separating machine, after selecting powder, particle diameter is: 325 mesh sieve margin≤1%, simultaneously, send particle diameter > 325 objects back to ball mill and continue to grind, qualified mixed raw material is delivered in maintenance storage tank;
C, mixed raw material stop >=24 hours in maintenance storage tank, after the surface electrostatic and stress that discharges fine powder, raw material is delivered in raw material silo, then by high-precision bunker scale weighing system, delivered to facility for granulating and granulate until raw material;
D, select the facility for granulating with dry powder automatic humidification system and introduction automatic weighing system to granulate, material temperature in pelletization is no more than 40 ℃, when raw material mixes after the raw grain of making water content 8～9% for 90～110 minutes in facility for granulating, by life grain by feed belt, tiltedly carry and being transported in the storage bin of centre;
E, according to the particle diameter requirement of the production program, utilize trommel screen to sieve raw grain, and by powder beater by the coarse grain that is greater than particle diameter requirement through carrying out fragmentation, then deliver to facility for granulating upstream, the particulate that is less than particle diameter requirement is directly done to introduction and delivers in introduction storehouse;
F, the qualified raw grain of particle diameter is tiltedly carried to dryer, utilized rotary kiln waste heat to dry raw grain, bake out temperature is no more than 150 ℃, requires the moisture content in raw grain to dry to 1～2%; Dry qualified raw grain through bolting to screen out shedding part, remaining is sent into rotary kiln and prepares finished product; Require rotary kiln temperature≤480 ℃, temperature≤800 ℃, low temperate zone, high low strap and temperature of kiln head≤1400 ℃;
G, that the finished product of preparation is sent into cooler is cooling, so that finished product temperature is down to normal temperature.
Further, the facility for granulating of applying in described method is support roller formula frequency conversion automatic discharging nodulizer.
Further, in the C step of described method, raw material send skewed slot, disk feeder, batching screw rod or pneumatic mode to be sent in high-precision bunker scale weighing system by wind.
Further, each step in described method is all controlled by fully automatic electric sub-control system.
Owing to adopting technical scheme as above, the present invention has following beneficial effect:
Of the present inventionly utilize ceramic tile to grind method that waste material produces ceramsite sand to have substituted the bauxitic clay in ceramsite sand raw material with the grinding waste material of building tile glaze, and utilize and be rich in K
2o and Na
2the ceramic tile of O grinds waste material as fusing assistant, has reached and when lesser temps, has formed 3Al
2o
3.2SiO
2the object of phase and liquid phase, this not only can acceleration of sintering process carrying out, but also can accelerate base substrate to the direction variation of low surface energy, the speed that makes material migration, pore reduction simultaneously and get rid of is accelerated thereupon, last shrinks by cumulative volume again and density increase becomes base substrate to have the dense multicrystalline sintered compact of some strength; Owing to can effectively reducing the sintering temperature of work in-process blank, therefore, described method is energy-conservation but also environmental protection not only, also has good economic and social benefit simultaneously; In addition, utilize ceramsite sand that described method is produced not only can meet every physical and chemical index of ceramsite sand, but also can reduce approximately 20% production cost, meanwhile, described method can also the corresponding effective ceramics factory that solves be ground a processing difficult problem for waste material for ceramic tile.
