Description
Technical field
The present invention relates to sand equipment technical field processed, particularly relate to a kind of dry method sand machine processed.
Background technology
Along with the pulling of domestic demand, the various places highway, the input of capital construction such as railway increases day by day, presses for a large amount of sandstones.In order to protect the ecological balance, country expressly forbids excavating without authorization natural sand (except the cleaning river course).Natural sand does not catch up with demand greatly for amount.Therefore, the exploitation of machine-processed sand has just very placed on the agenda urgently.In view of after machine-processed sand is rock blasting, form through Mechanical Crushing and screening through Mechanical Crushing or cobble, performances such as its intensity are all superior than natural sand.On the other hand, some metal and non-metal mine produce a large amount of mine tailings in mining and process, press for comprehensive utilization.
Sand equipment processed has jaw crusher, impact breaker, centrifugal impact crusher, cone crusher, vibrating screener, multi-functional drum sieve etc. at present; Be divided into two kinds in dry method sand processed and wet method sand processed by production method.The main Quality that present machine-processed sand equipment sand processed exists in producing:
A, the grain type bad, the faller gill shape is too much, and the rock problem is arranged here, but main be that lectotype selection causes, be that jaw crusher or hammer mill cause.
B, grating are not exclusively reasonable, and modulus of fineness is bigger than normal, and most enterprises reduce production costs for reducing mechanical wear, and the machine-processed grain fineness number modulus of production mostly is more than 3.0, and the concrete batching modulus of fineness is preferably in about 2.6.
The stone flour that c, wet method sand processed exist is the problem of washing away all.The mud powder is harmful to for concrete batching, must strictly control its content, to note equally except soil in machinery sand production processed and the use, remove mountain skin soil and interlayer soil, but must not be placed on the operation of washing off at last less than the particle of 75 μ m except soil, because stone flour also is the particle less than 75 μ m, but stone flour is different with the mud composition in the natural sand, the particle diameter distribution is different, role is also different in concrete, stone flour is useful to concrete, the existence of an amount of stone flour is arranged, remedied the shortcoming of machine-processed sand concrete batching workability difference.Adopt the last washing process in the wet production, that washes away is not only earth, simultaneously, has also washed away useful stone flour, has destroyed the grating of sand.
Summary of the invention
The present invention proposes at the problems referred to above, provides a kind of dry method sand machine processed.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of dry method sand machine processed, by charging aperture, upper shell, lower house, milling roller, roll dish, bearing, apparatus for examination and repair, inner sieving mechanism, working cylinder, scraper plate, discharging opening, reductor, shaft coupling, main motor, foundation bolt is formed, charging aperture is arranged on the center on upper shell top, discharging opening is on the base plate of lower house, milling roller is evenly distributed in upper shell and rolls on the dish, inner sieving mechanism is fixed on the upper shell by adjusting device, the bearing support milling roller, the weight of upper shell and lower house, bearing links to each other with the basis by foundation bolt.
The wear-resisting roller shell of described milling roller outer setting, roller shell adopt rich chromium cast iron or steel-casting to add resurfacing welding material.
The described dish that rolls is gone up the preparation abrasion-proof backing block, and liner plate is by many combinations, and liner material quality is that rich chromium cast iron or steel-casting add resurfacing welding material, rolls dish and links to each other with the reductor output flange, and motor drives reductor by shaft coupling and mill rotates together.
Described inner sieving mechanism is made up of screen frame (unit), sieve sheet, stationary ring, and it is fixed on the upper body by adjusting device.
Abrasion-proof backing block is equipped with in described upper shell inside, and liner material quality is 16Mn or casting wear-resistant liner plate.
The abrasionproof liner plate is equipped with in described lower house inside, and liner plate is the casting wear-resistant plate.
Described scraper plate is installed in the below of rolling dish.
Described apparatus for examination and repair is made up of maintenance hinged-support, maintenance cylinder.
Operation principle of the present invention is: the raw material that sand processed is used enters from upper shell central feeding mouth, rolling dish rotates together by the driven by motor reductor, material is under the grinding pressure and shearing force effect of milling roller, material is earlier broken again through the shearing force shaping of milling roller through rolling of milling roller, make material become the discharge gate that fine grained forms from the rotating ring that rolls the dish outside and the stationary ring on the inner sieving mechanism and be discharged into lower case, and the part bulk materials that escape in the milling roller gap without fragmentation is got back to by the inner sieving mechanism retaining and is rolled in the dish, continue grinding and enter lower case to qualified sand material, the sand material that enters lower house draws off at the discharging opening from the lower house under the effect of scraper plate.The grinding pressure of milling roller pressurizes by master cylinder in addition, and this pressure can be adjusted arbitrarily, and grinding of raw materials speed to be the gap length that rotating ring by rolling the dish outside and the stationary ring on the inner sieving mechanism are formed adjust.
Beneficial effect of the present invention: size and rotating ring and the stationary ring gap of the rolling pressure by adjusting milling roller, can adjust sand-grading easily, control rational modulus of fineness, adjusted the content of stone powder in the machine-processed sand, simultaneously under grinding pressure and shearing force effect, the machine-processed sand faller gill shape of producing is less, and particle shape is good.The present invention has controlled content of stone powder suitable in the machine-processed sand by dry production in addition, has optimized the grating of machine-processed sand, has saved water resource simultaneously.
