How to calculate conveyor system design

Cách tính toán thiết kế hệ thống băng tải

To automate the production process, you need to know the rules for designing a complete, efficient conveyor system. In the article below, Sukavina will guide you on how to calculate the design of a conveyor system.

1/ Choose the right type of conveyor design

Conveyor belts are designed for the purpose of transporting products from one location to another. When there is a need to transfer a fixed, boxy product, etc. then it is necessary to design a flat conveyor. Conveyor belts are used to prevent product from spilling on both sides while transporting bulk, crumbs and small items directly onto the conveyor belt.

2/ Choose a trough conveyor with 2 or 3 supporting rollers

With trough conveyors with a width of 600mm to 800mm, you can design a cluster of 2 passive supporting rollers.

Conveyor belts with 3 supporting rollers are applied in cases where the conveyor belt is 800mm wide or more and has a large conveyor belt deflection.

3/ Calculate the width of the conveyor

The width of the conveyor system is designed depending on the load capacity required by the customer, i.e. the total mass and dimensions of the product on the conveyor.

Typically, the larger the product being loaded onto the belt, the larger the width required by the conveyor will also be.

4/ Calculate the design of the lifting angle of the conveyor belt

When calculating the design of a conveyor system, calculating the angle of inclination can be quite difficult. Each different load product, including the nature of the product loaded at the time of shipment (e.g. moisture, size, width of the loaded product) will significantly determine the maximum allowable tilt angle of the product. design.

If the tilt angle calculation exceeds the allowable limit, the product on the conveyor belt will drift backwards when the load is uphill or slide down inertia and may fall out when the load is downhill.

In case the workshop space is limited and it is necessary to calculate the maximum angle of inclination when designing the conveyor belt, it is recommended to test with the sample product to be loaded and conduct a factory test with the type of belt you intend to use. The higher the tilt angle, the shorter the conveyor belt, saving workshop space.

There are a number of features to keep in mind when choosing a conveyor, including the ability to slide back products while using PVC conveyor belts and the ability to increase the anti-drift effect for heavy loads, complex structures, granular, etc. Ribbed PVC conveyor belts are an option that increases backwash resistance for boxy products.

In general, if your product is not too heavy or too slippery, the conveyor has an inclination angle of less than 30 degrees, then you do not have to worry about this problem. When the tilt angle is over 30 degrees, the same design can still be used, just choose the conveyor design more carefully.

5/ How to calculate the power and transmission ratio of the conveyor motor

Two important factors when choosing a conveyor motor are power and gear ratio. Motor productivity is often related to the size of the conveyor belt and the load of the product moving on the conveyor.

The gear ratio in the reducer is usually related to the required conveyor speed required. This problem is quite complicated, so Sukavina’s engineers will support you wholeheartedly so that the conveyor belt works most effectively.

6/ How to choose the right conveyor belt

In conveyor design, there are many different types of conveyor belts, including PVC conveyors, PU conveyors… It is possible to design conveyor systems without using conveyor belts such as roller conveyors, divided into two types: free roller conveyor and drive roller conveyor.

PVC Conveyor: The most common usage, low cost, easy to fabricate, and easy to replace the conveyor belt.

PU Conveyor: Similar to PVC conveyor belt, but mainly used in the food industry and for the production of electronic components.

7/ What type of belt is used for 2-way transportation?

PVC and PU conveyor belts are suitable for use when 2-way movement is required. The structure of the gear in contact with the conveyor or the drive mechanism is important when the conveyor is driven by a pulley or a gear chain.

Chain drive mesh conveyors, such as chain conveyors and chain driven mesh chain conveyors, can be transported in two ways.

With mesh chain conveyor designed with direct gear drive, 2-way running is not possible.

8/ How to calculate the speed of the conveyor?

Conveyor speed is usually calculated according to customer requirements and usually includes a number of specifications as follows: Motor rotation, gear ratio and drive pulley shaft diameter.

9/ When is it necessary to design more rollers to support the conveyor surface?

During the PVC conveyor belt design calculation, if the conveyor width is 500mm or more and the conveyor length is more than 15m, there will be a lot of friction between the belt and the bearing face. Due to friction, the drive pulley will be forced and the load will increase, making it unable to pull the load.

The roller supports the conveyor, which reduces the friction between the belt and the idler. Depending on the weight of the load bearing product, the length and width of the PVC belt, you can arrange the distance from 700mm to 1000mm.

Above is how to calculate conveyor system design. At Sukavina, our team of experts will advise, design and install your conveyor to ensure maximum efficiency in the production process.
