SELECTION AND LINE INTEGRATION
The right questions.
Clear answers.
Bag weight, dimensions and hourly throughput are the starting points for conveyor selection.
If the correct vibration level is selected, the objective is "distribution/balanced placement"; settings are adjusted according to the product and the bag.
Pneumatic or mechanical pushing/diverting principles are applied based on the line scenario.
Bag weight + line capacity (bags/hour). Layout and automation requirements follow.
In bag filling and palletizing lines, the conveyor does more than just transport; it corrects the bag's shape, levels the material, verifies the weight, and automatically rejects faulty bags. Metkan belt conveyor solutions... line synchronization, low maintenance requirements, and stable bag flow ...are offered in 5 different types specifically designed for bag lines.
When the following conveyor types are positioned at the right point in the filling–weighing–palletizing chain, downtime decreases, pallet quality improves, and shipping standards are raised.
Bag Conveyors

Vibrating Conveyors
Vibrating conveyors are specialized conveying systems that ensure the material inside the bag is distributed evenly after filling and that the product takes on a uniform shape. METKAN The vibration conveyors generate a vibrating motion via square rollers, ensuring the material is evenly distributed within the bag. This improves product appearance and enhances palletizing stability.
Widely used in the construction chemicals, cement, food, and agricultural sectors, these systems boost filling line efficiency and facilitate more organized, balanced packaging processes.
Applications
- Post-filling bag material leveling stations
- Construction chemicals, cement, and gypsum filling lines
- Food, agriculture, and chemical industries
- Systems preceding automatic weighing and palletizing lines
Key Features of Vibration Conveyors

- Durable Design: Long-lasting bearing system and heavy-duty steel body.
- Increased Efficiency: Accelerates the palletizing process by optimizing the bag's shape.
Weighing Conveyors
Weighing conveyors are systems that enable the automatic measurement of product weights while the products are in motion. METKAN Weighing conveyors offer accuracy, speed, and efficiency on production lines through high-precision load cell systems and digital control panels.

THE NEXT STEP
Let’s plan your line together.
Five conveyor functions for bagging lines
Belt conveyors and bag handling conveyors are selected by their role in the line. This family covers filled bag transport, bag flattening, vibration-assisted settling, weight checks and rejected bag removal. Belt width, speed and transfer heights must match the filling and palletizing equipment.
A bag flattener shapes the filled package before palletizing. A settling conveyor helps distribute the material inside the bag through motion. Their mechanisms and positions in the line differ, even though both help prepare a more consistent package.
The weighing conveyor measures the filled bag; the reject conveyor removes bags outside the agreed acceptance criteria. Checkweigher accuracy, line speed, calibration and the rejection mechanism must be specified together for the application.

How Is Belt Conveyor Capacity Calculated?
Knowing a belt conveyor’s width is not enough to state how many tonnes per hour it will carry. For bulk materials such as limestone or aggregate, the real question is: what mass flow results from the safe load cross-section on the belt, the selected speed and the material’s bulk density? This guide explains the theoretical calculation, a worked assumption and a practical check.

How Is Motor Power Selected for Belt Conveyors?
Belt conveyors transport materials systematically within production facilities. The system ensures a continuous flow of products between the equipment on the production line. However, the conveyor's performance is determined by several technical factors. Foremost among these is the selection of the belt conveyor motor power. If the motor power is insufficient, the conveyor struggles under load. The motor draws higher current, and the belt struggles to reach the target speed. This directly reduces production capacity. Prolonged strain also shortens the service life of the motor and gearbox.

How Are Belt Conveyor Length and Width Determined?
Determining the length and width of a belt conveyor is one of the most critical technical decisions for businesses establishing production lines. This is because a belt conveyor does more than just transport products; it dictates the line's rhythm, the product flow pattern, and the operating pace of downstream equipment. An incorrectly sized belt conveyor results in capacity loss, leads to product accumulation, and creates imbalances along the line. Conversely, a correctly sized system balances the flow, ensures safe product transfer, and boosts operational efficiency. Therefore, belt conveyor dimensions are not determined solely by the available space; factors such as the type of product to be transported, capacity targets, line direction, speed, load distribution, and site layout are all evaluated together.
Read the technical articleLine Efficiency in Belt Conveyors
Belt conveyor line efficiency directly impacts material flow along the production line. Conveyors facilitate the transfer of materials between crushing, screening, mixing, packaging, and palletizing stages. Consequently, even a minor conveying issue can lead to capacity loss across the entire line. Belt misalignment, incorrect speed, irregular loading, or a lack of maintenance quickly disrupts the production flow. Moreover, these issues do not merely reduce tonnage; they also increase energy consumption, cleaning time, and maintenance costs. If the source of the problem is not identified early, unplanned downtime occurs more frequently. Therefore, belt conveyor performance directly influences the overall efficiency of the production facility.
