Embodiment Construction

[0008] Embodiments of the present invention: when implementing a method of utilizing silt and municipal waste to make ceramsite of the present invention, take 50 parts of silt or sludge, 20 parts of municipal waste, shale water content of 50 to 70% by weight. 100 copies; first remove the metal materials in the municipal waste (if the municipal waste is municipal solid waste or / and construction waste without metal materials, the process of removing metal objects is not required), and then the shale, municipal waste Use conventional crushing equipment to pulverize and then put it in a mixer and mix it with sludge to obtain mixed raw materials. Use conventional granulation equipment to make the mixed raw materials into spherical raw materials, and control the diameter of the spherical raw materials at 1 to 20 mm. This is beneficial to the next step of the processing technology; then the spherical raw material is dried and puffed at a temperature of 380-420°C for 10-30 minutes, and...

Abstract

The invention discloses a method for making ceramsites by utilizing slush and urban garbage, which comprises the following steps: fetching 40-60 parts by weight of slush or sludge with water content of 50-70 percent, 15-25 parts by weight of urban garbage and 90-110 parts by weight of shale; crashing the shale and the urban garbage, mixing and stirring, the shale, the urban garbage and the slush, and then making pelletal material; drying and swelling the pelletal material for 10-30 minutes at the temperature of 380-420 DEG C, then firing for 5-10 minutes at the temperature of 1050-1150 DEG C and discharging, and naturally cooling to obtain the finished ceramsites. The invention not only has the advantages of low production cost, simple process and no need of clay as raw material, but also changes waste materials into valuable matters, and reduces the environmental pollution.

Description

technical field [0001] The invention relates to a method for making ceramsite by utilizing silt and urban garbage, and belongs to the technical field of ceramsite production. Background technique [0002] Ceramsite products are widely used in construction, environmental protection, metallurgy, chemical industry, petroleum, agriculture and other departments, especially because ceramsite has the functions of heat preservation, moisture resistance, sound insulation and vibration resistance, so ceramsite has been widely used in the construction industry Applications. At present, there are many methods for producing ceramsite. Although these methods have certain advantages, they generally have the problems of high production cost, complicated process, and the need to use clay as a raw material for production. Clay has become a country that needs to be protected. resources, therefore, the existing method of producing ceramsite is not ideal enough. Contents of the invention [...
