Abstract

The invention provides a coal ash powder material recovery system and method for dry mixed mortar production. During the production and drying process of dry mixed mortar aggregation, the recovery technology of automatic discharge, storage and delivery is realized by utilizing the coal ash powder material generated by a coal burning hot air furnace, the recycle of wastes can be realized, and a new choice is provided for the drying production line of the dry mixed mortar aggregation.

Description

technical field [0001] The invention relates to the field of dry-mixed mortar production, in particular to a coal ash powder recovery system and recovery method for dry-mixed mortar production. Background technique [0002] Ready-mixed dry-mixed mortar products are a new building material product in my country. Since the late 1980s and early 1990s, with the development of the national economy, it has been introduced into the domestic building material market. In the past ten years of development, ready-mixed dry-mixed mortar products have gradually been recognized and accepted by the market. Ready-mixed dry-mixed mortar product is a new type of energy-saving building material, which is widely used in building wall masonry, plastering, indoor and outdoor decoration and indoor and outdoor floor construction materials. In order to prevent the product from agglomerating and being scrapped during the shelf life, dry-mixed mortar products require that the raw materials used for p...
