Comprehensive utilization production line for solid waste tailings and tailing building garbage

Abstract

The invention discloses a comprehensive utilization production line for solid waste tailings and tailing building garbage, belongs to the field of building mechanical equipment, and particularly relates to a concrete aggregate production line. The comprehensive utilization production line for solid waste tailings and tailing building garbage can produce and machine building garbage and industrialtailings, and meanwhile, traditional raw materials can be treated, such as cobblestone machining treatment; according to the technical scheme, the comprehensive utilization production line for solid waste tailings and tailing building garbage comprises a tailing production line, a building stone production line and a comprehensive production line; discharge outlets of the tailing production line and the building stone production line are in butt joint with the comprehensive production line through a conveyor belt; according to the client requirement, different raw materials are treated, materials of different granule sizes can be produced, various combination modes are obtained, the production requirement can be met, meanwhile, the investment cost is lowered, and the product competitiveness is greatly improved.

Description

technical field [0001] The invention relates to a production line for comprehensive utilization of solid waste tailings and tailings construction waste, which belongs to the field of construction machinery and equipment, and specifically relates to a concrete aggregate production line. Background technique [0002] As one of the pillar industries of the national economy, the construction industry has developed rapidly in the past two decades. With the vigorous progress of urban construction, demolition has become the main theme of every city. Demolition will generate a lot of construction waste. [0003] These rubbish are mainly red bricks, reinforced concrete and their mixtures. At present, the amount of construction waste in my country has accounted for 30% to 40% of the total urban waste. The annual discharge of construction waste has exceeded 400 million tons, of which Beijing, Shanghai and other big cities have an annual discharge of more than 30 million tons. Most o...

Problems solved by technology

But so far, the relevant work of recycling construction waste in my country is relatively lagging behind, which has brought various adverse effects on society, environment and resources.

[0004] The use of construction waste and industrial tailings to produce concrete aggregates and other industrial products is the main trend in recent years, but the general production line cannot take into account the production and processing of traditional raw materials (pebbles, etc.) and construction waste and industrial tailings, and setting up two production lines significantly increases investment cost, reduce production efficiency
