Filling search collection gangue material crushing process of entry and practice




Blanking process tape transport → → → charging big shaker screening → ballast blocks into the feed hopper → → by small vibrating screen into the crusher → Transport →

blanking tape Description: raw materials are first screened by the large vibrating screen, part of the material falling into the belt transported to the stockpile, and the

remaining bulk material into the hopper

The feeder to the small shaker by small vibrating screen into the crusher machine, the crusher fall belt stockpile.

660V and 380V power distribution using two voltage which crusher 660V, all other uses 380V, total system power is 141KW. (Power supply system diagram) 2, the device starts

running the program equipment: two belt → → small vibration crusher Screen → → large feeder vibrating screen equipment

Stop: boosted sieve → → small vibrating feeder crusher sieve → → two belt 3, the major technical problems with the pure material handling gangue stone are very different,

the main difference between the first gangue in iron, easy destruction crusher, and iron can not enter the filling material; Second gangue often by

In the rain, underground sprinkler and other reasons to become wet, causing the machine not function properly broken; Third gangue in wood, wire mesh and other production waste,

will affect the crushing and waste rock aggregate quality. Therefore gangue crusher need to solve the following three technical issues: a deal with gangue of iron

Pieces; 2, wet conditions for complete crushing plant; 3, various types of debris sorting.

Solve these three issues in order to ensure normal production and waste rock aggregate technical requirements.

For the first question, we took three measures: 1, loading links have someone to pick up early, to prevent large iron pieces such as beams, columns, rails, etc. into the system;

2, in the shaker fixed magnet, prevent large iron pieces such as iron shoes, said splint, snap ring, etc. into the break

Crusher; 3, a magnet mounted on the transport belt, such as the small pieces of iron wire, screws, etc. from the shaker magnet drain fled after the absorption of iron from the

transport belt will net; For the second question, we took two measures: 1, charging will dry material and wet material to match, ensuring broken material

Not too wet; 2, with vibrating screen primaries, the fine material directly into the belt, feed the massive coal gangue crusher; against the third question, we took two

measures: 1, in the loading, warehousing, transportation, warehousing and other sectors arrange sorting; 2, vibrating screen choose a reasonable slope

Degrees, so that the speed gangue material appropriate for staff sorting; 4, to deal with the security problems in system operation, we found that some of the factors that

affect the safety of production, we passed by taking reliable measures to prevent security incidents.

Electric shock our main measures are: 1) to do a special grounding, grounding of all equipment systems; 2) All operating voltage becomes 36V; 3) switch must be "big four"

(leakage, grounding, overcurrent, missing items) complete protection; 4) maintenance equipment must be open

Off blackout atresia; material stone splashing wounding a) All wheels must have a guard; 2) Crusher port security fortification fly belts and anti-fly chain; 3) key parts of the

staff to wear helmets and protective eyewear; electric welding time prevent fire accidents a) welding work around 15m strictly prohibited flammable

Explosives; 2) welding supply line to ensure integrity; 3) oxygen, acetylene bottles spacing maintained over 5m safe distance; 4) torch, pressure gauges, back firearms to ensure

intact; 5) to comply with the relevant safety technical operation; 3.4 Other incidents 1) do a good job in the trenches around the barricade to prevent personnel

Falls; 2) prohibited from height to throw the material; 3) into the equipment maintenance must blackouts; 4) from the magnet to take iron pieces must be parked equipment; 5) man

and forklifts to protect more than 2m safe distance; 6) Waste Dump turn When someone below the non-material; 7) forklift in reclaiming waste dump to have someone care when

; 5 Conclusion In filling aggregate production practice there are a number of issues need to be further refined and improved, such as dust and reliable measures taken to reduce

or eliminate the dust; study of high strength hammer, hammer to reduce the frequency to change or replace other forms of crusher; non-iron materials by hand sorting

And difficult to pick up to do, should be done to fill the entrance shaker screening and other problems.
