DTⅡ belt conveyor is a general-purpose fixed belt conveying equipment widely used for bulk material transportation. Its code contains a clear technical positioning: "D" stands for fixed belt conveyor, "T" represents general-purpose, and "Ⅱ" is a serial number, marking its standardized and serialized characteristics formed in the process of technical iteration. As a key equipment for continuous material transportation in industrial production, the DTⅡ belt conveyor realizes efficient material transfer through the circular movement of the Conveyor Belt. With stable structure and strong adaptability, it has become a core conveying equipment in industries such as metallurgy, mining, coal, ports, power stations, building materials, chemicals, light industry, and petroleum.

Although Zoomry Heavy Industry, as a professional belt conveyor manufacturer, does not directly name specific products with "DTⅡ", the general-purpose fixed belt conveyors we produce are highly consistent with DTⅡ belt conveyors in terms of design concept, technical standards, and application scenarios, especially in long-distance and complex working conditions, fully reflecting the core advantages of this type of equipment.

Core Features of DTⅡ Belt Conveyor

The design of DTⅡ belt conveyor follows the principle of "component serialization", meeting different terrain and working condition requirements through modular combination:

Wide Material Adaptability

DTⅡ belt conveyor can transport various bulk materials (such as ores, coal, sand, etc.) and finished products with a bulk density of 500~2500kg/m³. It can form a conveying system through single or multiple combinations, flexibly adapting to different production capacity requirements. The conveyor belt and idler components produced by Zoomry Heavy Industry are specially designed to reduce material segregation, degradation, and contamination, and are particularly suitable for transporting high-hardness and highly abrasive materials.

Environmental Adaptability and Customized Protection

The conventional working environment temperature of DTⅡ belt conveyor is -25°C to +40°C. For special scenarios (such as high temperature, severe cold, humidity, corrosive or flammable and explosive environments), functions such as heat resistance, cold resistance, waterproofing, corrosion resistance, explosion protection, and flame retardancy can be achieved by adding protective devices. The conveyor components (such as idlers and pulleys) produced by Zoomry Heavy Industry adopt high-grade materials and sealing technology. For example, the sealing performance of idlers far exceeds the national standard - China's GB standard requires that water intake does not exceed 150g after 72 hours of immersion, while Zoomry's standard controls it within 100g, effectively improving the stability of the equipment in harsh environments.

Efficient and Energy-Saving Operation Characteristics

DTⅡ belt conveyor reduces energy consumption through optimized structural design, and the performance of its core components directly affects the operation efficiency. Taking idlers as an example, the rotational resistance of idlers produced by Zoomry Heavy Industry is ≤2N, and the rotational speed can reach 600r/min under a radial pressure of 250N, significantly reducing power loss; at the same time, the service life of idlers exceeds 50,000 hours, greatly reducing maintenance frequency and costs. In addition, the operating noise of the whole machine is controlled at 40-45dB, meeting environmental protection requirements and suitable for noise-sensitive scenarios such as around residential areas.

Core Components and Technical Standards of DTⅡ Belt Conveyor

Idlers

Idlers are key components that support the conveyor belt and materials, and their precision directly affects the stable operation of the equipment. The idlers of Zoomry Heavy Industry strictly control radial runout and axial displacement: the radial runout of idlers with length <550mm is ≤0.4mm, and the axial displacement under 500N pressure is <0.4mm, ensuring stable operation of the conveyor belt and reducing deviation and wear.

According to different functions, idlers can be divided into trough-shaped carrying idler groups, transition idler groups, buffer idler groups, etc., adapting to different conveying angles and material impact scenarios. For example, buffer idler groups can absorb the impact force when materials fall, protecting the conveyor belt; friction aligning idler groups can automatically correct conveyor belt deviation, improving operation safety.

Pulleys

Pulleys are responsible for driving, redirecting, tensioning and other functions. The pulleys of Zoomry Heavy Industry adopt high-strength materials and precision processing technology: 40Cr rolled materials are used when the shaft diameter is ≤190mm, and 40Cr forgings are used when the shaft diameter is ≥200mm to ensure torque resistance; the pulley shell is processed by a CNC four-roll rounding machine, with a plate thickness of 30*2700mm, ovality <1.5mm, and after welding, it undergoes ultrasonic flaw detection and tempering to eliminate stress, with a service life also exceeding 50,000 hours.

Other Key Components

• Conveyor belt: Made of wear-resistant and tear-resistant materials, and special materials such as flame-retardant and anti-static can be customized according to material characteristics;
• Tensioning device: Adjust the conveyor belt tension through hydraulic or mechanical methods to ensure stable conveying;
• Safety protection devices: Including belt deviation switches, pull rope switches, etc., which can stop the machine in time when the equipment is abnormal to ensure production safety.

Application Scenarios of DTⅡ Belt Conveyor

Industry Adaptation Cases

• Mining and metallurgy: Transporting bulk materials such as iron ore and copper ore, which need to cope with large inclination angles (up to 18°) and high production capacity requirements. Zoomry Heavy Industry improves material stability by designing trough-shaped idler groups, and cooperates with buffer idlers to reduce the damage of ore impact to the equipment;
• Coal and electric power: In coal mines and thermal power plants, explosion-proof and flame-retardant requirements must be met. Equipment components are made of anti-static materials, and the conveyor belt is added with flame retardants, meeting industry safety standards;
• Ports and building materials: Used for transferring bulk materials (such as sand, cement), forming long-distance conveying systems through multiple series connections. Zoomry Heavy Industry's experience in long-distance belt conveyor EPC projects (such as cross-sea and cross-highway scenarios) can ensure efficient linkage of the system.

System Design Principles

The design of DTⅡ belt conveyor must follow the principle of "terrain adaptation + process requirements":

• Terrain adaptation: Convex arc segments and concave arc segments can be designed for undulating terrain; when passing through tunnels or residential areas, low-noise components and closed structures are used to reduce environmental impact;
• Process integration: Supporting with feeders, screening equipment, etc., to form an integrated "receiving-conveying-unloading" process. The customized services provided by Zoomry Heavy Industry can optimize the conveying angle, speed and unloading method according to the specific needs of customers, such as realizing full automatic operation through PLC control systems to reduce manual intervention.
