Description
Technical field
The invention belongs to building materials processing units field, relate to a kind of particle shaping equipment, be specially a kind of deep processing production unit of aggregate.
Background technology
Coarse aggregate and fine aggregate are the indispensable important component of concrete batching.A large amount of scientific research and engineering practices show that the particle shape of coarse aggregate and fine aggregate is very big to the influence of performance index such as concrete workability, intensity and weather resistance.When thick, when the fine aggregate particle shape is relatively poor, its voidage and specific surface area are big, increase with the slurry contact surface, the water absorbent surface amount increases, friction resistance increases, and being used for concrete batching can increase water consumption, reduces concrete workability, intensity and weather resistance, must increase the slurry consumption if want to guarantee concrete strength, thereby increase concrete folk prescription cost.
One, the particle shape of natural aggregates such as river sand is better, and being directly used in the concrete preparation can meet the demands.But, fast development along with building trade, construction work increases day by day to various demands thick, fine aggregate, raw materials such as river sand are as natural resource, can not regenerate in short period of time, after large scale mining use for the previous period, in the many areas of China relevant natural resources situation in short supply has appearred.In recent years, along with relevant natural resource reduce day by day and people to the improving constantly of conservation of resources attention degree, utilize raw material production regeneration aggregate such as discarded concrete to be used to prepare the effective way that concrete becomes solution resource scarcity problem.But, China mainly prepares regeneration aggregate by simple crushing and sieving technology at present, the regeneration aggregate corner angle that this method obtains are many, surface irregularity, also contain more hardened cement mortar in the component, add concrete blocks and in shattering process, cause a large amount of tiny cracks in inside because of damage accumulation, cause the porosity of regeneration aggregate self big, water-intake rate is big, tap density is little, voidage is big, the crush index height, the regeneration concrete water consumption of this regeneration aggregate preparation is bigger, intensity after the sclerosis is low, Young's modulus is low, and impervious, frost resistance, anti-carbonization ability, shrink, creep and performance such as resistance of chloride ion penetration all is lower than normal concrete; On the other hand, the regeneration aggregate performance difference that the concrete of different intensity grades is prepared by simple crushing and screening is very big, and the high more regeneration aggregate performance that makes of common concrete intensity is good more, otherwise the regeneration aggregate performance is poor more.The used concrete strength grade of different sites of different buildingss or same building thing also is not quite similar, therefore the regeneration aggregate concrete blocks in the building waste is directly broken, that screening prepares is poor performance not only, and the quality discreteness of product is also bigger, be unfavorable for applying of product, can only be used for low intensive concrete and goods thereof.In addition, in order to solve the problem that natural sand materials such as river sand, lake sand reduce day by day, adopted the way of made sand to substitute natural sand at present in the engineering, but machine-processed sand is compared with natural sand, mechanism sand grains shape is coarse, multi-angular, unfavorable to concrete workability, in order to satisfy the construction needs, reach the workability identical with the natural sand concrete, need to strengthen water consumption, the result who does has like this caused the increase of water cement ratio, thereby cause concrete strength and weather resistance to reduce, or the gel material content increase, concrete folk prescription cost increased.
In order to improve the performance of regeneration aggregate, the general practice in the industry is regeneration aggregate to be carried out physical strengthening handle.Existing physical strengthening equipment comprises following two big classes, one class is to remove the particulate corner angle by abrasive method, realization is strengthened the particulate shaping, but these type of physical strengthening equipment ubiquity wearing and tearing are big, power and shortcoming such as energy expenditure is big, production efficiency is low, are difficult to large-scale promotion application; Another kind of is to utilize the principle of high-speed impact that aggregate is carried out shaping, and for example the described abrasive material trimming machine of Chinese patent ZL92216898.9 etc. is compared and ground the class strengthening device, such physical strengthening equipment have power consumption less, advantage such as production efficiency height.But because this kind equipment in the course of the work, the shaping position is subjected to the high-speed impact and the friction of material particles all the time, so the equipment attrition problem is outstanding, and service life of equipment is generally lower.On the other hand, because the device interior working-surface is more level and smooth, the mutual grinding effect between aggregate and the equipment and between aggregate and the aggregate is less, influences shaping effect.In addition, because the speed of a material material is higher in the working process, therefore effectively the shaping cycle is shorter, and the final shaping strengthening effect of material particles is on the weak side.
