Advanced Technology Fly Ash LECA Production Line Plant Equipment For Sale
Fly Ash LECA Production Line Description:
Capacity:10000-30000(t/a)
Main Materials:Clay, Sludge, Shale, Fly Ash
Main Equipment:Ball Mill,Oil fracturing proppant Kiln,Granulator
Fly Ash LECA Production Line Plant Production Process:
1.Crushing.The size of bauxite from mine is around 300~500mm, low
moisture, After two-stage crushing which is composed by Jaw crusher
and hammer crusher, the size of bauxite will be around 25mm.
2. Dosing. Bauxite, manganese powder, and other additional material
will be transferred to belt conveyor through belt weigher to make
sure the suitable proportion .If the moisture of bauxite or other
material is more than 6% need to be drying at first .
3. Grinding. In grinding process ,the main equipment is ball mill
and separator to make a close-circuit grinding system .The
granulator required the material size will be lower than 300mesh .
4. Granulator. Raw material powder after grinding stored in hoppers
.generally there have 2-3 hoppers, it can be discharged separately,
also can be discharged with many hoppers collocation. Raw material
powder will be transfer into a small silo, the silo has screw
metering device or belt weigher .The material will be conveying to
granulator, meanwhile the water will be spraying to granulator by
pipeline pump. When granulator rotating, the raw material can be
made into various particle size Raw ceramic sand will be
transported to rotary sceen by belt conveyor, qualified sand will
be calcined in rotary kiln, and the oversize will returns to raw
material grinding process. The granulator system is totally
automatic, continuously, matching with bag-type dust collector, can
purification the exhaust air.
5.Calcining. Raw ceramic sand be calcined in rotary kiln , with the revolution and slope of rotary kiln, calcined ceramic sand move toward to the kiln head, meanwhile, pulverized coal spray into the kiln burner from kiln head, raw ceramic sand will be calcined into ceramic sand with high intensity in the rotary kiln.
6. Pulverized coal preparation. Pulverized coal preparation use ball mill or vertical mill, which can drying the coal with hot wind from kiln hoodsl. Use separator can adjust the fineness of pulverized coal at will; it provides sufficient conditions for full burning of pulverized coal.

7.Fineshed product cooling.The cooling of ceramic sand genergally
use rotary cooler, it is simple and reliable when working,
secondary air of cooler absolutely enter to the kiln, multi-channel
burner, can save a lot of energy. The temperature of ceramic sand
after cooler is very low, can be touched by hand.
8.Screening. Ceramin sand after the cooler can be directly
transported to multistage vibrating screen, it can be divided into
many particle grade according to requirements.
9.Packing. Ceramic sand after screening will be transported to
different silos , the silos connected with packing machine ,
finished products will be transferred to storage house to prepare
for delivery. All dust points in the process need match with dust
collector to purification the exhaust air .
