Zero Pressure vs Minimum Pressure Accumulation Conveyors

November 11, 2021
Accumulation Conveyor

Accumulation conveyors have many benefits in distribution facilities, shipping centers, or to queue up goods for sorting just to name a few. These types of conveyors temporarily slow down or holds items until they are released without back pressure buildup. There are two types of accumulation conveyors: zero back pressure and minimum back pressure. The main difference between these two accumulation conveyors is that zero pressure will keep items from touching, and minimum pressure has a continuous flow of packages so that they are allocated evenly.

In-order to choose the best accumulation conveyor style for you, it’s important to take the items being transported into consideration. Are they fragile where product cannot have a build-up of line pressure? Or does your business convey light to medium sized cartons, boxes, and bins.

Zero Pressure

Zero pressure accumulation conveyor are one of the most widely used conveyors when buffering and regulating product flow. Zero pressure systems create a buffer for items while being conveyed. This buffering helps to keep products from touching each other while getting transported. Zero pressure conveyors help to decrease the risk of items being damaged during accumulation and are often used in distribution facilities, shipping centers, or to queue up goods for sorting. Zero pressure accumulation conveyors use photo-eyes and electronic controls without any use of pneumatic logic. Ideally this type of conveyor is often used for sorting, wrapping, palletizing, strapping or many other processes within a facility. This type of conveyor offers higher reliability, increased product output, low maintenance, and quiet operations. These can be used on declines, inclines, and spirals.

Minimum Pressure

Minimum pressure accumulation conveyors are much different from zero pressure accumulation conveyors. Accumulation conveyors with minimum pressure create a constant flow of packages so that they are allocated evenly or held back when the conveyor line isn’t ready for additional products. This helps to eliminate the build-up product flow when there is conveyor line congestion, product backups, or blockages. When packages are stopped, pressure is kept to a minimum to eliminate package and product damage. The amount of back pressure can be set and is usually around only 2% of the total load being carried on the conveyor. This is made possible through use of a spring adjusted carrier, which can sense the driving friction required to maintain movement without accumulating pressure.

Accumulation conveyors allows operators to time production flow at times in-between work areas. For over 30-years American Surplus Inc. has been designing and installing conveyor systems in warehouses across the country. Here at ASI, we specialized in used, and each unit is hand inspected, tested, and clean prior to shipment. We guarantee our conveyors will work upon arrival (excluding freight damage).
