The introduction of sludge ceramsite equipment

Sludge ceramsite is using sludge as main raw material, adding the amount of materials, into a ball, roasting. Start soon the sludge Ceramisite at home and abroad, the current applications are mainly concentrated in the sludge as organic additives in a ceramsite firing, use less, only about 10%, process conditions and ingredients than the urgent need optimization.

The main equipment of the production of lightweight aggregates include: raw material storage bins, dust chamber, induced draft fan, the main kiln, coal injection system, control cabinet and so on. Which raw materials position in the lower part of the feeders, the kiln speed and amount of arch coal are variable speed, in order to adjust the process parameters to get the maximum yield under the premise of ensuring product quality.

Ceramsite is a building material. Most of its exterior features are round or oval sphere, there are a number of imitation gravel ceramsite irregular gravel like. The ceramsite shape due to different processes and different. Its surface is a layer of a hard shell, and ceramic or enamel layer shell is impermeable, the security role of gas and must be given to the high strength of ceramsite. Ceramsite particle size is generally between 5 and 25mm. Ceramic, generally is used as instead of concrete, gravel and pebbles. It makes the concrete under the premise of diminished strength, greatly reducing the weight of the concrete. Ceramsite with low density, light weight, insulation, thermal insulation characteristics, and good physical properties , can also be a filter as the water treatment.

Ceramsite has the characters of small density, lightweight, heat insulation, thermal insulation, superior fire resistance, good anti-seismic performance, low water absorption, frost resistance and good durability, impermeability performance, strong adaptability, good ornamental effect. It is widely used in many fields such as oil fracturing support agent, building materials, refractories, insulation materials, water purification, horticulture, food and beverage, chemical industry and other departments, whose extensive application continues to expand.

Requirements on raw materials of ceramsite production is not high and materials are almost everywhere, for example: clay, slate, mudstone, shale, coal gangue, fly ash, mud and industrial solid waste can be done for ceramsite sand raw materials. No matter what the raw material used for the production of ceramic sand, basically can be divided into material homogenizing, granulating, baking, cooling process. According to material types and characteristics, the granulation processing technique :

1.plasticity process technique

2.the mud into ball technique

3.grinding into ball process technique

4.crushing process technique

The main equipments of ceramsite production line:

Including raw material storage bin, a dust settling chamber, a draught fan, the main kiln, pulverized coal injection system, control cabinet, etc. The feeder at the bottom of raw materials warehouse, kiln speed and arch coal quantity are all stepless speed regulation, in order to adjust its parameters and in the premise of ensuring product quality to obtain the maximum yield.

The ceramsite production line distinguishing features:

1, reasonable layout, process flow, high degree of automation;

2, mechanical joint control operation, low labor intensity;

3, the calcination parameters of real-time monitoring, firing good quality products;

4, output to energy consumption rato is high , low running costs.

This ceramic sand can reduce the secondary pollution. Ceramsite calcined at high temperature environment can be completely biodegradable organic matter, pathogens, heavy metals and other harmful substances are decomposed and curing, with a certain degree of economic and environmental benefits. Sludge fired ceramsite can not only save clay, but also protect farmland, playing a certain role in environmental protection.
