Description

technical field

[0001] The invention relates to a water-cooled vacuum kneading machine for ceramic mud, especially honeycomb ceramic mud. Background technique

[0002] Honeycomb ceramics is a kind of porous ceramics. Due to its high specific surface area and high porosity, it is widely used as a three-way catalyst carrier for automobile exhaust purification and as a regenerator for preheating and recovery of metallurgical industrial waste gas. The thermal stability, compressive strength and other physical and chemical properties of honeycomb ceramics affect its use function, and its physical and chemical properties are directly related to raw materials and processing technology. The kneading after kneading of honeycomb ceramic raw materials is an important part of the processing technology, that is, kneading under vacuum conditions can further improve the uniformity and compactness of each component. In order to eliminate the heat generated by mechanical stirring, it is nec...
