Background technology

Brick mixed building rubbish is the building waste be made up of clay brick and concrete.In China, the building of building before 2000, has two kinds substantially, brick-and-concrete buildings and xoncrete structure building.Usual brick-and-concrete buildings rubbish, based on broken spent clay fired brick, is auxiliary with broken waste concrete; Usual xoncrete structure building, such as xoncrete structure factory building etc., based on broken waste concrete, are auxiliary with clay brick.

Brick mixed building garbage as resource regenerates, and is the particle diameter becoming to meet required for cement based building materials raw material by brick mixed building garbage crushing, i.e. regeneration regenerated coarse aggregate, recycled fine aggregate, the large regrown material of regenerative micro powder three.

Data shows, the most of mineral resources more than 70% of China transfer to ground, transfer to city.The natural sand and stone resources of China is fewer and feweri.Sustainable development is accomplished by China, must make full use of " city mineral products " resource.Urban building waste resource, more and more need fine design, being not only and giving full play to the effect of different building waste wood property, the needs that housing project material greenization especially, fine design manufacture, is also the needs that construction refuse resource process enterprise creates economic benefit.

Number of days is rained mostly more than 120 days in south China area, and rainy season is cloudy and drizzly for days on end, and thus southern brick mixed building msw water content is normality more than 10%.Traditional impeller impact sand production machine, makes below 5mm Machine-made Sand below 50mm stone, usually sand coarse aggregate ratio 25-40% processed, and namely circulation percentage of damage reaches 60-75%, sand energy consumption 8-10 degree electricity/ton processed.The brick mixed building rubbish that moisture content is higher has wet, sticky, light feature, and in small, broken bits is adopt impeller impact sand production machine, and practice shows, sand coarse aggregate ratio processed only has 10-15%, and 85-90% needs circulation broken, and sand energy consumption processed reaches 20 degree of electricity/tons.This be brick mixed building rubbish through moisture in shattering process, the powder of generation is attached on impeller counterpunch board and on crusher chamber interior lining panel, brickbat particle is comparatively light in addition, lacks kinetic energy, and counterattack is clashed into broken and particles collision crushing effect is poor.In fact, moist brickbat particle is larger than stone toughness, brickbat particle High Rotation Speed under the impeller of High Rotation Speed drives, it more acts on is polishing, particle and particle, particle and wallboard temper, shear pulverizing, and mixing particle to brick is " grinding little ", but not " broken little ", thus its crushing effect is poor, and shaping effect is better.
