NN-200 Nylon Conveyor Belt used nylon conveyor belt for sale

Why the NN-200? The Strength Factor

Our primary concern was strength and durability. We're moving tons of ore every day, and the last thing we need is a belt failure causing downtime. The NN-200, with its 200 N/mm per layer tensile strength rating (that's what the "200" stands for), seemed like a good fit. It's a step up from the NN-150, and that extra strength gave us peace of mind.

My Main Concerns (and How They Were Addressed):

• Question 1: Will it really hold up under constant heavy loads?

• Answer: So far, so good. The multi-ply nylon carcass (we opted for a 6-ply configuration) provides excellent tensile strength. It's rated at a minimum of 15 MPa overall, and that's been more than enough for our needs.

• Question 2: How about abrasion resistance? Our material is pretty rough.

• Answer: This was a big one for us. Turns out, the NN-200 has excellent abrasion resistance. They use a testing method under the GB/T7984-2001 standard, and the wear volume is less than 200mm³. In practice, that means it's holding up really well against the sharp, jagged ore we're transporting. We also chose the wear-resistant cover option for added protection.

• Question 3: Is it flexible enough for our conveyor system's setup?

• Answer: Yes. We have some pretty tight turns and inclines in our setup, and the NN-200 handles them without a problem. It's surprisingly flexible for such a strong belt.

• Question 4: What about maintenance? How often will we need to replace it?

• Answer: Obviously, regular inspections are key. But the NN-200 is designed for a long service life. With proper care and maintenance, and by following guidelines like storing it between 18-40°C and 50-80% humidity, we're expecting it to last for a good while. We also make sure the belt doesn't run faster than 2.5 m/s to minimize wear.

• Question 5: Is it suitable for the density of our materials?

• Answer: Our materials fall within the 0.5-2.5 t/m³ density range, which is perfect for the NN-200.

Key Specs That Mattered to Me:

• NN-200: Each layer has a tensile strength of 200 N/mm.

• Width: We went with a 1500mm wide belt, but it's available from 100mm up to 3000mm.

• Plies: 6-ply configuration for extra strength. You can choose from 2 to 10 plies.

• Cover Thickness: We opted for a 6.0mm top cover and a 3.0mm bottom cover, which works well for our needs. You can customize between 1.5-8.0mm for the top and 0-4.5mm for the bottom.

The Verdict:

After months of use, the NN-200 Nylon Conveyor Belt has proven to be a reliable workhorse. It's tough, durable, and handles our demanding conditions with ease. While it's a significant investment, the increased efficiency and reduced downtime have more than made up for the cost. If you're in a similar industry and need a belt that can handle the pressure, I'd definitely recommend considering the NN-200, or even stronger versions like the NN-250 or NN-300, depending on your specific needs. You can choose the right belt based on your needs.
