preparation example Construction

[0022] The invention provides a method for preparing dry-mixed mortar based on construction waste treatment, which can process construction waste and use construction waste to prepare dry-mixed mortar, which reduces processing costs, concentrates dust removal, effectively controls dust pollution, and does not require encapsulation of equipment , can achieve full environmental protection and green production, please refer to figure 1 ,

[0023] The dry-mixed mortar preparation method based on construction waste treatment comprises the following steps:

[0024] S1: Stone breaking: the construction waste is crushed by a crusher, so that the whole piece of construction waste is split into fragments of different sizes, and the metal materials in the construction waste are taken out;

[0025] S2: Crushing and screening: Put the pieces of different sizes in the pulverizer for crushing, and use the electromagnet to screen out the metal powder in the pieces of the same size, and the d...

Abstract

The invention discloses a dry-mixed mortar preparation method based on construction waste treatment, and relates to the technical field of construction materials. The dry-mixed mortar preparation method based on construction waste treatment comprises the following steps that construction waste is crushed through a crusher, so that the whole construction waste is split into fragments with different sizes, and metal materials in the construction waste are taken out; the fragments with different sizes are crushed in the crusher, and metal powder in the fragments is screening out through an electromagnet; raw materials are conveyed into a bucket elevator through a bin bottom belt; crushed aggregate enters a linear vibrating screening machine through a vibrating feeder to be screened, and screened over-limit materials are conveyed to the bucket elevator through a return hopper to be circularly crushed. The construction waste can be treated, the dry-mixed mortar is prepared from the construction waste, the processing cost is reduced, centralized dust removal is achieved, dust pollution is effectively controlled, equipment is not required to be packaged, and full-environment-friendly green production can be achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing dry-mixed mortar based on construction waste treatment. Background technique [0002] Building materials are various materials used in construction engineering. There are many kinds of building materials, which can be roughly divided into: (1) Inorganic materials, which include metal materials (including ferrous metal materials and non-ferrous metal materials) and non-metal materials (such as natural stone, burnt earth products, cement, concrete and silicate products) Wait). (2) Organic materials, which include plant materials, synthetic polymer materials (including plastics, paints, adhesives) and asphalt materials. (3) Composite materials, including asphalt concrete, polymer concrete, etc., are generally composed of inorganic non-metallic materials and organic materials. [0003] Dry-mixed mortar refers to a granular or physical mixture of a...
