Description
Technical field
The present invention relates to Machine-made Sands to manufacture field, and in particular to a kind of high performance concrete is produced with Machine-made Sand and filled
It puts.
Background technology
With the raising of people's environmental consciousness and to reduce the destruction to natural resources, the use of natural sand has been subjected to
Stringent limitation will gradually exit building materials market, and be replaced by Machine-made Sand.Machine-made Sand belongs to the fine aggregate in concrete, is
Refer to by Mechanical Crushing, grain size is less than the rock particles of 4.75mm.Due to the popularization and application of high performance concrete, production meets high property
The Machine-made Sand that energy concrete needs is the trend of domestic sandstone industry development, and Machine-made Sand traditional at present is using crushing and screening
The mode of production, it is unreasonable there are grain composition, the problem of content of stone powder excessive (being higher than national standard permissible value).
Traditional selects powder mode to carry out selecting powder using sand washer or powder concentrator, needs to consume a large amount of water moneys using sand washer
Source, and sewage forms secondary pollution, and using powder concentrator, then energy consumption is big, uneconomical.
There is producer to select powder using the method for pneumatic separating at present, individually increasing a batcher in pneumatic separation device front end carries out
Material is spread out.Since pneumatic separating is added in vibrating screen front end, larger inventory to be treated (is 30%- generally into sand coarse aggregate ratio
50%), and in order to promote selection by winnowing effect, need blower air quantity big, deduster air inducing fan delivery is thus caused also to increase,
Dedusting area increases so that energy consumption and investment greatly increase.
The Chinese patent application of 104876463 A of Publication No. CN discloses a kind of dry type Machine-made Sand production system, including
Sequentially connected crusher, feeding machanism, selection by winnowing screening plant.The dust removal port connection primary dust removing equipment of selection by winnowing screening plant
Import, the import of the air outlet connection wind turbine of primary dust removing equipment, the outlet of wind turbine connects the air inlet of selection by winnowing screening plant respectively
The import of mouth and two-stage dust removal equipment, the crude product of selection by winnowing screening plant flow back into crusher, the top setting of selection by winnowing screening plant
There are dust removal port and feeding mouth, be provided with side air admission mouth below feeding mouth, sieve, selection by winnowing are provided in the middle part of selection by winnowing screening plant
The lower part of screening plant is provided with the product outlet below the sieve and the crude product positioned at sieve lower end outlet lower section
Outlet, feeding mouth are connected with the discharge port of the feeding machanism.The technical solution can effectively remove the mountain flour in Machine-made Sand,
But selection by winnowing screening plant is after being connected to crusher, vibrating screen front end, be for it is entire it is broken after in coarse granule and fine grained
Mountain flour is handled, and energy consumption is big.
The Chinese patent application of 104384004 A of Publication No. CN discloses a kind of Machine-made Sand production system and method, breaks
Broken machine is equipped with feed-crushing mouth and broken discharge port, and for being crushed to raw material, vibrating screen is connect with broken discharge port, receives
Particles of aggregates after crusher in crushing, and the particles of aggregates of reception is sieved, vibrating screen is provided with coarse granule discharging
Mouth and fine grained discharge port, wind-force powder selection device are connect with fine grained discharge port, and winnowing powder, winnowing powder are carried out to fine grained
Device setting mechanism sand discharge port and mountain flour discharge port.In the technical solution, since vibrating screen has spread material out in itself
Effect, there is no need to individually increase oscillating feeder to spread material out, reduces Machine-made Sand production difficulty and environmental pollution, also reduces
Energy consumption, but its it is unified to mountain flour extract out, without after-treatment, air blower wind control is too strong or insufficient, can all cause mechanism
The grain composition of sand can not ensure.
Therefore, the problems such as Machine-made Sand production process is complicated, big, seriously polluted, Machine-made Sand the grain composition of energy consumption is unreasonable,
It is the technical issues of those skilled in the art are urgently to be resolved hurrily.
