简体中文 Hey there, newbie friend! Are you confused with a bunch of PVC conveyor belt parameters? Especially when you see the word ”thickness”, you will have a big headache - choose thin for fear of cracking, choose thick for fear of expensive? Don't panic, today we will break open the crumbs to talk about this matter!To put it bluntly, choosing thickness is the same as picking shoes: whether it fits or not depends on how you use it!
🔍First, understand: thickness in the end affect what?
(I'm sure you've muttered: what difference does a 1mm difference make?)
Honestly.Thickness directly determines the “life” of the belt.Thin belts are flexible and save money but are afraid of heavy work! Thin belts are flexible and save money but are afraid of heavy work, thick belts carry the build but are bulky and costly. To give you a chestnut 🌰:
- 2mm thin tape: like sneakers, lightweight and power-saving, suitable for passing cell phone cases in electronics factories and transporting cookies in food factories (web page 1 mentions light-duty scenarios)
- 8mm thick tapeLike work boots, wear-resistant and smashing-resistant, it is indispensable for ore transportation in mines and ingot delivery in steel mills (webpage 2 says that it must be thickened for heavy loads).
🧩Second, the 3 key factors: the right number can be selected!
Key 1: Are you shipping cotton or iron? --Material Characteristicsset the tone
(Don't laugh! Someone really used a thin belt to transport iron sand, and it was scrapped in three days!)
- light and airy type(<10kg/㎡): e.g. cardboard boxes, foam boards →1-3mm is sufficientThe cost savings also reduce energy consumption (web page 4 emphasizes the selection of thin strips for light materials).
- heavy(>50kg/m2): e.g., ore, metal parts →At least 5mm to startOtherwise, it will be deformed in minutes (page 6 directly states that the load determines the thickness)
- sarcastic(sharp edges): e.g., gravel, scrap steel →Thickened + wear-resistant layer! Otherwise there are more scratches and direct leaks (page 1 mentions the need for impact resistance)
💡personal recommendation: Don't just look at the weight! Material humidity and corrosiveness also have to be figured out - chemical plant transporting acid? Remember to choose a thickened anti-corrosion coating!
Key 2: Is the conveyor belt a sprint or a marathon? -Conveyor distance determines endurance
(Think about it: can you run 100 meters in the same shoes as you run a marathon?)
- <10 m short range: Thin tape is sufficient, e.g. for packing table turnover →The king of 2-3mm price/performance ratio(Example of thin tape for short distances on page 2)
- >50 meters long distance: It must be thickened! Otherwise the belt is like a rubber band that gets looser and looser.Choose 5mm or more with a fabric coreThe tensile resistance does not run away (webpage 5 says that high tensile resistance is needed for long distances)
📢The truth about the industryMany factories run long lines with thin belts in order to save money, and as a result, the motor pulls desperately, doubling the cost of electricity and always stopping! This account can not scratch ah!
Key 3: Is the work environment a greenhouse or a battlefield? --The working environment determines life expectancy
(Warm and dusty? Thickness needs to be “buffed”!)
- High-temperature workshop(>60°C): e.g., ceramic kiln →Thickness + temperature resistant layer! Ordinary PVC goes limp when it gets hot (webpage 7 requires a heat-resistant overlay)
- Wet environment: e.g. aquatic lines, washing machines →Thickened non-slip pattern3mm glossy tape turns into a slide when exposed to water (webpage 9 recommended herringbone pattern thickened tape)
- chemical corrosion zone: e.g. electroplating plants →Special thickened rubber surfaceThinness is easily “chewed” by acids and alkalis (page 4 emphasizes chemical resistance)! Thinness is easily "eaten through" by acids and alkalis (page 4 emphasizes chemical resistance).
🛠️Three,Guide to avoiding the pit: The 3 most common mines stepped on by newbies
- The superstition of “the thicker, the better.”→ Result: The motor is overloaded and the meter is spinning like crazy!
correct posture: Food factory choose 2mm green belt, than use 5mm power saving 30% (web page 1 actual test data) - Neglect joint strength→ Result: The belt didn't break, the joints crumbled first!
remedial action: Thick straps (>6mm) must be fitted with mechanical buckles, don't glue them! (Page 8 clarifies the standard of mechanical joints) - Not looking at the support structure→ Result: Thick belt on a small pulley? Straight up jammed!
Golden RuleRoller diameter ≥ belt thickness × 100 times! 1cm thick belt has to be equipped with 1 meter large roller (hidden formula on page 3)
💎I'll end with something heartfelt.
I have been working on conveyor belts for more than ten years, and I have seen too many people fall on “almost”!Remember this mnemonic: “Light cargo short distance thin with fast, heavy cargo long distance thick with handsome, the environment is bad plus buff, save a small amount of money will be a big loss!”The next time you choose the thickness, the bill of materials, wiring diagrams, environmental photos dumped to the supplier - professional things to professional people, we do not smell?
(If you are still not sure? (If you're not sure, take a look at the real-life examples of Addis on page 1, and the 2mm green band with non-slip design on page 9.)
