Product IntroductionThe DTL Series General-Purpose Fixed Belt Conveyor, also known as a belt conveyor or rubber belt conveyor (commonly referred to as conveying equipment), is primarily used in coal mines for main or transport roadways to move raw coal. It can also be applied in open-pit coal mines, surface transport, and material handling in other industries. Depending on roadway slope changes, brakes and backstop devices can be added. The conveyor can operate horizontally or on an incline. This series features a simple structure, high versatility, high efficiency, easy operation and maintenance, and supports long-distance continuous transport. The head drive unit can be installed on the left or right side according to roadway conditions. It comes with a complete set of electrical control and protection systems to enable automated operation. For high-capacity transport, high-power motors can be used, with multi-point drive design if necessary. Soft-start functionality is possible using a variable frequency drive (VFD) starter or CST-controlled starting device.
Key Performance Features
1. Stable and Efficient Conveying Capacity
Designed with a fixed structure and precise belt tensioning system to ensure uniform belt tension. Materials are transported smoothly without accumulation, allowing long-term stable conveyance of bulk materials and meeting the needs of continuous production.
2. Robust and Durable Structure
Core components such as the frame and idler supports are made of high-strength steel and treated with anti-corrosion processes like hot-dip galvanizing or plastic spraying. This provides excellent impact resistance and corrosion protection. Idlers use high-quality bearings with wear-resistant rubber layers, offering low running resistance, long service life, and adaptability to heavy loads and complex working conditions.
3. Easy Installation and Maintenance
The fixed structure requires no frequent disassembly. During installation, it can be quickly secured using embedded parts and foundation bolts.Routine maintenance only requires periodic inspection of idlers, lubrication of bearings, and removal of material accumulation on the belt,reducing operational costs significantly.
4. Wide Application Scenarios
Suitable for mining, construction materials, chemical, port, and other industries. It can transport coal, ore, sand, gravel, grain, and other materials, and is adaptable to open-pit, enclosed, or humid environments.
5. Energy-Saving and Environmentally Friendly
The drive system combines a high-efficiency motor with a gearbox, providing high transmission efficiency and low energy consumption. The belt operates smoothly with low noise, meeting industrial requirements for energy-saving and environmentally friendly production.

ApplicationProduct DetailsMain Components
The belt conveyor is divided into four main parts: head unloading device, drive unit, tensioning device, middle section, and tail section.
1.Head Unloading Device: Composed of the head frame, drive drum (serving as the unloading drum), and scraper.
2. Drive Unit: The drive unit powers the entire conveyor and consists of a motor, coupler, gearbox, drive drum, frame, and redirecting drum. The motor drives the drive drum via the coupler. The drive drum uses a welded structure, with a thick, wear-resistant cold-bonded rubber surface. This enhances friction with the conveyor belt to prevent slippage, reduces drum surface wear, and provides a self-cleaning effect.
3. Middle Section: The middle frame uses a channel steel fixed-frame structure. Each channel steel section is 3 meters long. The steel and support legs are bolted together. The idler frame channel steel is also bolted, making the structure simple, easy to assemble/disassemble, reducing labor intensity, and shortening operation time.
4. Tail Section and Tensioning Device: The tail section consists of the tail frame, tail drum, buffer rollers, lower idler rollers, plow-type scraper, and tensioning carriage. The tail drum is mounted on the tail frame with adjustable shaft alignment to correct belt tracking. Tensioning is achieved using a gravity carriage system.
