Which Accumulation Conveyor is Right? Minimum-Pressure vs. Zero-Pressure

Print Friendly, PDF & Email

So, what’s an Accumulation Conveyor?

Accumulation in a conveyor system refers to the process of temporarily holding products on the conveyor to manage flow and prevent bottlenecks. This allows for controlled release of items to downstream processes, ensuring a smooth and continuous operation.

In general, accumulation conveyors are categorized in two types: minimum-pressure and zero-pressure.

Minimum-Pressure Accumulation: How does it work?

Allows Light Touching and Budget Conscious

Minimum-pressure accumulation conveyors allow products to touch each other lightly when they’re stopped on the conveyor. This small amount of pressure helps keep things moving without causing damage to the products.

These conveyors are generally more affordable due to their simpler design. They use space efficiently because the products are closer together, and they are easier and quicker to maintain.

Minimum-pressure conveyors are best suited for sturdy products that can handle a bit of contact, high-volume operations that require moving a lot of products quickly and efficiently, and budget-conscious solutions.

Zero-Pressure Accumulation: How does it work?

No Touching – Damage is Not an Option!

On the other hand, zero-pressure accumulation conveyors use sensors to keep products from touching each other. When one product stops, the next one stays a little behind it, ensuring there’s no contact between items.

This system is perfect for delicate or fragile items that can’t handle any pressure. It’s also versatile, working well with products of different sizes and weights, and offers precise control thanks to advanced sensors.

Zero-pressure conveyors are ideal for delicate items that need extra care, systems handling varied products of different shapes and sizes, and high-end products where damage is not an option.

When choosing between zero and minimum pressure accumulation, consider the following points:

Type of Products:  Fragile items need the gentle handling of zero-pressure conveyors, while sturdy items can usually manage on minimum-pressure conveyors.

Volume:  If you need to move a lot of products quickly, minimum-pressure conveyors are a good choice due to their higher throughput.

Budget Constraints:  Minimum-pressure conveyors are typically more affordable, making them a suitable option unless product protection is paramount.

Maintenance:  Zero-pressure conveyors have more parts and may require more upkeep, but they offer better product protection.

Available Space:  Minimum-pressure conveyors use space more efficiently because the products are closer together, which might be important if you have limited space.

Your Path Forward

Choosing between minimum-pressure conveyor and zero-pressure accumulation conveyors is like picking the perfect tool for the job. Take a good look at your products, consider your throughput needs, check your budget, think about maintenance, and measure your space. With a bit of careful evaluation, you’ll find the conveyor that fits your system like a glove. Make the smart choice and watch your operation run smoother than ever!
