简体中文 "Smashing millions to buy a conveyor line that cracks and deforms in less than half a year? Brother, you are afraid that this money is a waste of money!"Do this line for twenty years, seen too many newbies planted in the selection pit. Today we will nag some real - how to choose a long conveyor line in order not to step on the mine? Remember the five iron laws.Save enough money on repairs to replace your BMW!
First, the distance to determine the life and death: short in the long term selection of the world's different
Short range within 50 metres(e.g. intra-plant transfer):
- Closed-eye selection of fabric core tapes(EP/nylon material), the price is cheaper than wire rope core 30%!
- But watch out.If you are transporting high-temperature slag (>60°C), you have to go up to the top! If you are transporting high-temperature slag (>60°C), you must get on theHeat-resistant rubber layerOrdinary tape cracks in minutes when exposed to heat.
Medium range at 500 metre level(mine to processing area):
- Steel cord conveyor belts are a life saver! Tensile strength must be ≥2000N/mm
- lesson learnt through blood and tears: A factory used ordinary belts to save money, resulting in large chunks of ore crashing down.Three tears in six months.The cost of repairs is enough to buy two new belts!
Long distances over kilometres(cross plant/river crossing works):
- Tube Belt Machine Direct Seal of Approval! The enclosed design is not afraid of the elements and30° incline angle climbing(Ordinary belt limit is only 20°)
- Shenhua Indonesia project actual measurement.30km pipe belt machine saves land over conventional belt machine 40%We've saved ten million dollars in demolition costs alone.
The White Mantra: Short distance for wallet, medium distance for strength, and long distance for terrain!
Second, material characteristics are invisible killers! These parameters must shoot dead
| Material Properties | mortal risk | crack programme |
|---|---|---|
| Ore | Scratch through tape, jam rollers | Thickness of covering rubber ≥ 8mm + ceramic liner plate |
| High temperature coke | Tape distortion, release of toxic fumes | 160°C resistant silicone tape |
| sticky-wet coal sludge | Sticky belts run off and don't unload cleanly | Three alloy scrapers + high pressure blowing |
| fly ash | Pollution of the environment, complaints from residents | Closed Eye Selection Tube Belt Machines! Dust to zero. |
lit. tread the pits oneself: The cement factory transported lime powder without sealing it, resulting in the neighbouring farmland being covered with white ash.Payouts are more expensive than conveyor lines--Environmental red lines should never be touched!
Three, pipe banders really smell good? Read these three giveaways first!
Q: They say tube and belt machines save space, how good can they really be?
A: Look at the data set and see 👇
- Footprint Comparison: Equally transport 1000 tonnes/hour of pulverised coal
- Conventional belt conveyor: trestle width 6 metres
- Tube strip machine: the corridor is only 3 metres wide.Save half the land
- Turning God's work.: Minimum horizontal turning radius of 45 metres.Snaking around residential buildings(Conventional machines can only be dismantled.)
Q: How long does it take to pay back the cost of the expensive build?
A: Crane 30km case speak:
- High initial investment 15%
- butSave $14 million a year in electricity costs + maintenance-free transit stations2-year payback
Q: I heard it's easy to twist into a twist?
A: The key is in the transition paragraph!
- Wire Rope Core Belt: Length of transition section > 50 times pipe diameter (e.g. 25 metres of transition for φ500 pipe)
- anti-twisting measures: Add 1 set for every 10 sets of rollers.Self-aligning rollersAuto-correct for deviations exceeding 5cm
A teacher's advice.: Don't touch the pipe banding machine without professional operation and maintenance for mountain projects! There are less than 500 technicians in the country who know how to regulate.
Fourth, the list of cost black holes: these money saved must be overturned!
1. Cutting corners in the drive system
- Long distance mustMulti-motor split drive! Single motor strong? It's like a lorry burning up a hill--A steel mill in Hebei shut down production for three days as a result
2. Roller sets blindly assembled
- The waterproof rating of the rollers of the pipe belt machine must be IP65.! Ordinary rollers are rusted to death in case of rain, replace them once and stop the machine for 8 hours.
- a spacing trapMaterial density > 2.2 tonnes/m³, the distance between the rollers should be reduced to 1.2 metres (default 1.4 metres can not be carried).
3. Cold zone frost protection
- -25°C area must be usedCold Resistant Tape! Ordinary belts become brittle at low temperatures.It's like a biscuit that crumbles at the touch of a button.
A hard bargain.: Cheap to save $2 million on generic tape, only to spend $3 million more on annual repairs-That's a score a schoolboy could settle!
V. Future king bomb configuration: no five-year phase-out now
1. Intelligent sensing armed to the teeth
- Runaway detection + temperature and vibration monitoring: Failure rate reduced by 70% (refer to Indonesia project with 1200 days zero accident)
- variable frequency drive: Automatic speed adjustment according to material flow rate.Energy consumption cut 25%
2. Lightweight True Fragrance Warning
- New alloy bracket allows equipment to reduce weight by 10%.Save $300,000 on installation
3. Anti-corrosion buffs stacked
- Pickling plant conveyor line?Fluoroelastomer coverArrange on! Lasts 3 times longer than regular tape
A final pat on the shoulder and a heartfelt message.::
Extra-long conveyor lines are not FMCG.It's been 20 years.! Better to spend an extra three months researching than to bet on luck and buy blindly. Remember these eight words of truth."Distance sets the tone, material sets the material, terrain sets the machine, and cost sets the fate.". Dump this one on Purchasing next time you make a selection - they'll have to give you a bonus!
