Choosing an In-Plant Conveyor System for Your Production Line: A Comparison Guide by Type and Capacity

Why Conveyor Selection Is a Strategic Decision, Not an Afterthought

A conveyor system is often treated as a simple accessory linking the stations of a production line, when in fact it is one of the decisive factors shaping the line's real throughput, its unplanned downtime rate, and its annual operating cost. Choosing a conveyor type that doesn't match the product's nature, weight, or the manufacturing environment usually creates bottlenecks that only surface after installation and live operation — at which point fixing it becomes costly in both time and money.

Main Types of In-Plant Conveyor Systems

Belt Conveyors

The most common choice for packaging, food, and consumer-product lines. They offer smooth motion and even load distribution, and are available with PVC, PU, or rubber belts depending on the product and required temperature range. They need periodic maintenance of the belt and rollers to avoid slippage or tearing.

Roller Conveyors

Suited for moving boxes, pallets, and products with a rigid base. Available in gravity (free-rolling) or powered versions, they handle significantly higher loads than belt conveyors with relatively lower maintenance cost.

Chain Conveyors

A robust option for heavy loads and harsh industrial environments such as metal, ceramic, and wood processing lines. They tolerate high heat and debris better than belts, but come at a higher supply cost and produce more operating noise.

Screw Conveyors

Designed to move bulk materials — powders, granules, and dry chemicals — horizontally or at a slight incline. They provide enclosed transport that reduces contamination and product loss, and are common in food, feed, and fertilizer industries.

How to Calculate the Required Capacity and Speed

Before requesting a quote from a Chinese supplier, define three core values: the required output rate in pieces or kilograms per hour, the dimensions and weight of the unit being moved, and the actual distance between stations. From these you can calculate the belt or conveyor speed in meters per minute, and the width needed to avoid product buildup or gaps between pieces. It's always advisable to request 15-20% extra capacity margin above current throughput to accommodate future expansion without replacing the entire system.

Common Mistakes When Sourcing a Conveyor System from China

  • Choosing the conveyor type based on price alone without matching it to the product's actual nature and weight.
  • Overlooking temperature, humidity, or dust requirements of the factory environment when selecting belt material.
  • Failing to confirm that the conveyor motors' voltage and frequency match the local power grid.
  • Ignoring the height differences at transfer points between the conveyor and adjacent stations, causing flow bottlenecks.
  • Not ordering essential spare parts (rollers, belts, chains) with the first shipment, which extends downtime during breakdowns.
Golden rule: size your conveyor system around the slowest workstation on the line, not the fastest — the line's real speed is always set by its weakest link.
