The strength and fragility of the material introduced

The general performance of the material crushing strength of the degree of difficulty, also known as the fragility of the material. The same crusher crushed under the same

operating conditions of different materials, the production capacity is different, indicating that a variety of materials different friability.

Friability and the material strength, hardness, density, uniformity of the structure, water content, viscosity, cracks, surface condition and the shape factors.

Material strength and hardness are expressed resistance to external force, the strength and hardness of the material is difficult to Grand broken. But the mere hardness of the

material is not necessarily hard to broken, because the material is a block broken split open, so the crusher manufacturer difficulty determining factor is the material strength. The

hardness of the material must be very difficult grinding, crushing process because the grinding process and the different mill grinding process is the body of the material

surface constantly working to generate a large number of fine grinding process, therefore I decided to ease grinding factor is the material hardness.

Uneven nature of the natural material, the same material measured intensity data vary greatly. Therefore, in practical work often measured hardness of the material, the hardness

of the material to some extent reflects the ease of stone screening machine the material, the hardness of the material so that their common friability.

Hammer crusher maintenance and adjustment

Hammer crusher main working parts with a hammer (also known as the hammer) of the rotor. Rotor from the spindle, disk, pin and hammer. Working principle is motor driven rotor

rotating at high speed in the crushing cavity. Material from the upper mouth to feed into the machine, by the high velocity of the hammer blow and grinding. The lower part of

the rotor, with sieve, mesh size is less than crushing the grain discharged through the sieve, sieve size larger than the coarse sieve retention continue to be a hammer blow,

and finally discharged through the sieve machine outside. Only by understanding the hammer Mobile crushing plant works, in order to better safeguard hammer crusher.


One, hammer crusher, such as the coupling of the elastic sleeve damage is found, should be replaced.
Second, the product size can be adjusted by changing the sieve styles or sieve sieve rack mounted on the ends of the tank filler block embedded in order to change the screen of

the gap.
Third, the product adjusting the particle size can be adjusted by rotating the eccentric shaft to the hammer and the gap between the sieve.
Fourth, hammer crusher work, if a sudden strong vibration, should be immediately stopped, identify the cause and eliminate, and then start hammer crusher.
Five, hammer crusher hammer hit some wear and tear on one side, the other side can be reversed using.
VI hammer assembly or replacement, the balance of the rotor must be maintained. Each row of the shaft of the hammer hammer should correspond to the total mass of the hammer axis

equal to the total mass of the hammer, the total deviation must not exceed 1 00g. Quality single hammer little deviation ± 0.5kg.

Hammer crusher is suitable for crushing brittle, medium-hard, surface water does not exceed 2%, not more than 1 50MPa compressive strength of the various materials used in coal,

metallurgy, building materials, chemicals, electricity and other departments breaking or coal crushing plant, coal gangue, limestone, shale, feldspar, gypsum, coke, brick, brown iron

ore, gravel, salt and sulfur, phosphate rock and so on.

Tiger population Crusher

"Tiger mouth" is commonly known as jaw crusher, mining crushing process is the necessary equipment, it means that the tiger's mouth, put all of the ore shipped swallowed whole;

crushed ore beneficiation process in the first beneficiation production process, from underground mine shipped ore, hard as stone, as big as mill

Plate, do not crush them shrink twenty or thirty times, is not normally enter the grinding and flotation operations, which depends on the job crushing the divinity of the tiger

population. Broken someone suitable, crushing and screening plant was adequate, grinding load easily, large capacity, production targets and stability, power consumption, materials consumption are

reduced;

Crushing was inappropriate, grinding load increased, not only increased power consumption, processing indicators, let alone the cost of consumption. So beneficiation indicators

crushing is the premise. This depends on this "tiger mouth" was.
The advantage of a small power consumption, high efficiency, energy saving to the user, reduce costs. It is widely used in metallurgy, building materials, chemicals, coal and

other industrial sectors, for Mohs hardness of 7 or less variety of materials, coarse, medium, fine, when used vibrating screen manufacturers crushing, should use energy-efficient crushing jaw broken

Crusher. Suitable materials are pyrite ore, phosphate rock, heavy mineral crystal, lapis lazuli, calcium carbide, coke, limestone, etc., not for tablets ore crushing.

Scrap crusher line selection

Scrap iron and steel production, consumption generated from renewable raw material resources. Scrap iron and steel production as the necessary resources, is the only alternative

to iron ore raw materials. In addition, a carrier can scrap or raw materials. Recycling one ton of scrap steel, steel can be about 0.8 tons, saving the equivalent of two iron

ore

Tons to 3 tons, saving one ton of coke, waste gas, waste water, waste emissions can be reduced by 86%, 76% and 97% in favor of cleaner production and waste discharge reduction.

With the Chinese steel industry development and further implementation of sustainable development policies, scrap consumption will increase year by year, the market will scrap

Growing.

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.

Broken strange situation in the control operations integration and disposal

Successful experiences (1) after taking into account the expansion transformation may cause the actual coal warehouse cone pressure than the original increase, resulting in

pulverized coal flow variation. In order to increase the pulverized coal flow and a reduction of the compressed air into the water, in December 2006 at the end of the compressed

air into the coal

Flow system to help increase the pipeline before the dryer, and strictly control the coal moisture content does not exceed 1.0%. Also in the take-off artificial beat kiln coal   Semi-mobile crushing plant

silo cone and lower pulverized coal pipeline approaches to increase the mobility of .

(2) In order to prevent coal dust "knot arch", in January 2007 in the kiln silo cone adds air guns and vibration motor. After taking these measures, the phenomenon of broken

coal significantly improved, each class usually appear 1 to 2 times, each time 3 ~ 5min.

(3) In order to solve our broken coal kiln Pfister scale problems, in late June 2007 inspect the site and analyze that frequent the real reason for breaking coal flow aid

warehouse cone gas flow aid pipeline exports blocked, while gas shortage led to a flow aid, so that poor pulverized coal under aggregation  crushing equipment

. As production heavier tasks, not emptying the silo kiln handle this, the temporary transformation of the warehouse cone gas flow aid system, to be emptied after the planned

overhaul this thoroughly kiln coal warehouse processing. Temporary modification of specific measures are: to control the air flow past the solenoid valve

Instead straight into the style of the past after a plurality of solenoid valves removed, leaving only a total, annular flow aid directly from the main channel - on the next - a

few inflatable cone hose right positions.

Use effect after a period of use, the tail scales off coal phenomenon has been basically eliminated. Thereby stabilizing the kiln thermal system, avoiding the tail scales

frequently broken coal for clinker production quality. After transformation, the tail rotor load factor trend scales.

After transformation, the tail rotor load factor trend scales preheater system 2 partial pressure, temperature suddenly showing zero earlier in the kiln system during normal

operation, C1 ~ C4 cylinder and cone shaft preheater outlet temperature, pressure, all of a sudden by the normal becomes 0, the tertiary air temperature and pressure by the same

Normal value becomes 0, many a red alarm, the control operation screen. In this case, the control operator rapidly beating the air gun and notify local pressure field inspection

personnel check flap valve abnormalities hammer lever operation is flexible.

Preheater system pressure suddenly showing zero based on past experience, (a) when the preheater system clogging phenomenon are: ① gas pressure instability: clogging over many

parts of sharply negative, blocking parts (generally in the cyclone cone part) the following will soon decline even

To positive pressure; ② rapid temperature changes: clogged suspended in the air stream greatly reduced quantity of raw, raw materials and hot air can not be effectively heat

exchange, resulting in congestion levels over part of the temperature drop cyclone, blocking part of the following various parts of the abnormal temperature rise, especially in

blocking

Plug at the next level cyclone or calciner, because there is no raw material enters the gas temperature will surge; ③ often increased: (a) coal storage space; (2) coal and coal

storage warehouse within cones appear "knot arch", "scaffolding" phenomenon that can not be normal coal out of the warehouse; (3) raw coal silo and mill

The transfer device between failure or blockage. At this point, you must promptly find the mill feed interruption and fast processing; should also be closely monitored and out

into the grinding mill air temperature, because the temperature is too high to prevent spontaneous combustion or explosion of coal dust causes the mill feeding interruption time

More than 10min

Must stop grinding. February 2011 Henan a cement plant using bituminous coal mill coal feeding occur due to interrupt a long time, the control operator is not in a timely manner

into the mill hot air valve is closed, there is no cold air into the mill will be fully open valve, the results of wind temperature up to 150 ℃, coal mill bag filter dust bag

full within

Fire department, a considerable economic loss.

Coal mill electric ear vibration tendency anomaly coal mill electric ear vibration (grinding sound) meter installed in the field through the special structure of the probe, the

mill received the noise, the shielded cable to the instrument and converted to digital decibel instructions, while the output proportional with the decibel value 4 ~ 20mA

electric

Flow signal decibel value of the fill material is inversely proportional to the mill, the grinding media and the material is proportional to the weight ratio, so it can

quantitatively measure the size of the mill load. The operator can control the level of sound under ground coal flow into the mill, mill load in order to achieve the control of

the mill output

Highest and lowest power consumption. Coal mill normal production, electric ear vibration in a small range of fluctuation (), indicating incoming uniform mill load stable, then

mill the highest yield, lowest power consumption.
