Belt conveyors are categorized into various specifications and models based on different usage environments and requirements:
-
Customizable Width: The conveyor belt can be cut to any width according to customer requirements. This flexibility allows conveyor belts to be tailored for specific applications, such as narrow belts for small-scale operations or wide belts for heavy-duty industrial tasks, ensuring optimal performance and space utilization.
-
Classification by Usage Environment: Based on different environmental conditions, conveyor belts are divided into ordinary conveyor belts, which include subtypes such as standard type, heat-resistant type, flame-retardant type, burn-resistant type, acid-alkali resistant type, and oil-resistant type. Additionally, there are specialized belts like heat-resistant conveyor belts, cold-resistant conveyor belts, acid-alkali resistant conveyor belts, oil-resistant conveyor belts, and food-grade conveyor belts. These specialized belts are engineered with unique material compositions to withstand extreme conditions—for example, food-grade belts are made with FDA-approved materials to ensure safety in food processing, while flame-retardant belts are critical in industries like mining to prevent fire hazards.
- For ordinary conveyor belts and food-grade conveyor belts, the minimum thickness of the top cover rubber is 3.0mm, and the bottom cover rubber is 1.5mm. For heat-resistant, cold-resistant, acid-alkali resistant, and oil-resistant conveyor belts, the minimum thickness of the top cover rubber is 4.5mm, and the bottom cover rubber is 2.0mm. Depending on the specific usage environment, the thickness of the top and bottom cover rubber can be increased by 1.5mm. The thicker rubber covers enhance durability and resistance to wear, particularly in harsh environments like chemical plants or cold storage facilities, where belts are exposed to corrosive substances or extreme temperatures.
-
Classification by Tensile Strength: According to the tensile strength of the fabric layers, conveyor belts are divided into ordinary conveyor belts and high-strength conveyor belts. High-strength fabric conveyor belts are further categorized into nylon conveyor belts (NN conveyor belts) and polyester conveyor belts (EP conveyor belts). Nylon (NN) belts offer excellent flexibility and impact resistance, making them ideal for long-distance conveying, while polyester (EP) belts provide superior dimensional stability and low elongation, suitable for high-tension applications like cement or steel industries.
