The invention belongs to the technical field of industrial three waste treatment, and particularly provides a method for reutilizing waste of a calcium silicate board or fiber cement board productionline. In the production process of a calcium silicate board or a fiber cement board, dust generated in the working sections of sanding, edging and chamfering, ground leftover materials and waste boards are transported to a waste stock bin to be mixed to form reclaimed materials, the reclaimed materials replace the using amount of quartz sand raw materials with the preset percentage and are mixed into a tube ball mill for powder grinding, and thus mortar used for the calcium silicate board or the fiber cement board is obtained. According to the scheme, the waste of the calcium silicate board orfiber cement board production line is treated and then reutilized, the treating cost of the waste can be lowered, resources are effectively utilized, the environment is protected, and social economiceffects are created.
Description
technical field [0001] The invention belongs to the technical field of industrial waste treatment, and in particular relates to a method for recycling waste from a calcium silicate board or fiber cement board production line. Background technique [0002] As of the first half of 2019, there are about 100 enterprises producing calcium silicate board or fiber cement board in my country, namely calcium silicate / fiber cement board, with about 200 production lines and an annual production capacity of about 800 million square meters. With the acceleration of construction industrialization and housing industrialization, according to the national energy-saving emission reduction and green environmental protection policy requirements, the large-scale application of calcium silicate / fiber cement board as a new wall material will become a trend. Calcium silicate / fiber cement board has superior fireproof and waterproof properties, excellent heat insulation performance, good sound insula...
