The arrangement of rollers can guide the running direction of the conveyor belt. By setting the angle and position of the rollers reasonably at the turning point of the conveyor belt or where the direction of operation needs to be changed, the conveyor belt can smoothly turn or run along the predetermined route. For example, in the assembly line of an automated production workshop, the conveyor belt needs to shuttle between different workstations and change direction. The correct guidance of the rollers can ensure that the conveyor belt accurately delivers materials to various processing workstations, improving the degree of automation and efficiency of production.

Dimensional parameters
diameter
The common diameters of mining rollers include 89mm, 108mm, 133mm, 159mm, etc. Smaller diameter rollers are suitable for conveyor systems with smaller conveying volumes and lower belt speeds; Larger diameter rollers are better suited for working conditions with high belt speeds and large capacities. For example, in underground transportation tunnels of small coal mines, where the conveying distance is short and the conveying capacity is limited, 89mm diameter rollers may be used; In the main transportation system of large open-pit coal mines, 159mm diameter rollers may be used to ensure efficient and stable transportation.
length
The length of the roller is determined based on the width of the conveyor belt. Generally speaking, the length of the roller should be about 100-200mm smaller than the width of the conveyor belt. For example, for a conveyor belt with a bandwidth of 800mm, the roller length may be 600-700mm. This is to ensure that the rollers can effectively support the conveyor belt while avoiding interference with other components during operation.
Material and structural parameters
Cylinder material
The common materials for mining roller bodies include carbon steel, stainless steel, and plastic. Carbon steel rollers have high strength and low cost, making them the most commonly used material. Stainless steel rollers are suitable for environments with high requirements for corrosion resistance, such as use in mines containing corrosive minerals. Plastic rollers (such as polyethylene rollers) are lightweight, corrosion-resistant, and have a low coefficient of friction, but their load-bearing capacity is relatively low. They are commonly used in lightweight conveyor belt systems or places with high electrostatic requirements.
Axis material
The roller shaft is generally made of high-quality carbon steel or alloy steel. The diameter and material of the shaft determine the load-bearing capacity and service life of the rollers. For example, the roller shaft made of 45 carbon steel can provide good strength and toughness after appropriate heat treatment, meeting the requirements of most mining rollers.
