Coal Ash Ceramsite Production Equipment - Chinaprice: contact company for price
chemically to release gas, resulting in pores and expansion , after
cooling into the light porous and a certain intensity of sphere or
spherical silicates , particle size of which vary from 1mm to 10mm.
Ceramsite according to raw materials are divided into: ceramic clay,
shale ceramic, fly ash ceramic . Now also began to use the solid waste
incineration residue as raw material Ceramisite. Ceramic clay raw
materials can be clay sediments of rivers and all sorts of cleared
sludge in wastewater treatment plant. Shale ceramsite raw materials
contain coal gangue, limestone and other tail ore. Fly ash ceramic
materials is mainly powdery dust of thermal power plant.
Fly Ash Ceramsite application:
Fly Ash Ceramsite is used in the production of fly ash ceramic hollow concrete block. Using ceramsite for aggregate, pottery sand or volcanic ash slag for the accessories, cement and additives for adhesives, can be made into the mixed non-weight bearing or load-bearing hollow block products. Not only light weight, good insulation, Fly Ash Aggregate concrete shrinkage and frost resistance can meet the national standards system. The pulverized ceramisite instead of ordinary stones preparation of lightweight aggregate concrete, has been widely used in high-rise buildings, bridge beams, underground construction and other projects, both to reduce the epidermal density of the concrete, and improve the thermal insulation of concrete, fire-resistant, frost resisting, anti-doped , seismic and other properties. Fly Ash Aggregate strength of concrete are usually larger, more applicable to the preparation of high-strength lightweight aggregate concrete, the production of Fly Ash Aggregate concrete composite roof and wall pull. Fly Ash Aggregate concrete composite roof has advantages of good heat insulation performance, simple structure, easy construction, and is an excellent internal wall materials.
Coal Fly Ash Ceramsite preparation process:
1. raw material processing
Should be carried out wet ash dewatering in order to control the moisture content of the raw materials and clay should be dried and broken , during the process should adjust the carbon content of ash , clear about the other impurities in the raw materials.
2. raw material measurement
A variety of raw materials used in the base quality measurement, the measurement accuracy of ± 5%, otherwise it will affect the expansion of the lightweight aggregates performance and quality.
Fly ash, binder are put into the mixer for stirring , uniformly adding amount of water to make material moisture up to 20 % so as to make materials achieve required granulation plasticity.
4. granulation into a ball
Sintering technology adopts oncefiring, sintering time of 1 hour, the firing temperature of 1200-1300 degrees Celsius.
Coal ash ceramsite production line equipment:
1.The main machines used in ceramsite production line are primary crusher, secondary crusher, fine crusher, computer control raw material batching system, ball mill, bag type dust collector, high efficiency combined type powder separator, pelletizer, screening machine, rotary kiln, colling machine and final product screening machine. The process flow and machine collocation of ceramsite production can be adjusted in a small range according to different kinds of ceramsite. Especially for the construction ceramsite production, the quantity of machine needed can be reduced.
2.The production of fly ash ceramisite should use binoculars rotary kiln. It can alone control their speed of the kiln preheat section and drying section so as to control of their warm-up time depending on the state of the raw materials.
