TDG belt weigh feeder for Coal/Limestone/clinker/Mining

Based on the belt conveyor, the belt weigh feeder is an electronic measuring device which assembles the weighing bridge (referred to as the weighing frame) in the belt conveyor to continuously weigh and measure bulk materials. Widely used in metallurgy, building materials, electric power, mining, chemical industry and other industrial production departments.

Series belt weigh feeder,the scale frame structure is simple, compact, large stiffness, good stability, trunnion support, easy installation, high sensitivity, good linearity, can adapt to the harsher working environment, long-term stability and reliability. The high precision and high sensitivity S-type tension weighing sensor is installed in the sealed square beam, which is safe and stable, dustproof, waterproof, and resistant to external corrosion interference, and the force measurement state is good. Using inductance or photoelectric coding speed measurement sensor, the speed measurement accuracy is high, the signal is stable, not disturbed, can be transmitted over a long distance, high reliability. Using our HL-820 type or imported weighing controller, it has perfect function, simple and convenient adjustment operation, high reliability, small maintenance, and fully meets the requirements of different users and different grades.

Measurement control system
The metering control system of this machine is equipped with a LX series instrument featuring a 32-bit ARMCPU and a 24-bit ADC sampling module, with a sampling speed of up to 240 times per second. It has both Chinese and English menu displays, 6 analog inputs, 2 analog inputs, and 2 analog outputs. It is equipped with a standard RS485 interface (modbus protocol), which can be fully connected to the central control system to form a DCS system.

Native performance characteristics
The cantilever beam type bellows sealed load cell is adopted, featuring high accuracy of force/electricity conversion. The installation bracket of the sensor can ensure that it is not subjected to lateral force impact and has strong overload protection capacity, making the sensor less likely to be damaged.
2. The weighing body is equipped with an automatic belt tensioning and automatic deviation correction device to maintain a constant belt tension, and there is an alarm signal output for belt deviation exceeding the limit.
3. The weighing body is equipped with internal and external cleaning devices and unloading for the belt, effectively overcoming the problem of material adhesion and dust raising on the belt.
The weighing body exclusively adopts two cantilever beam high-precision sensors, which greatly improves the measurement accuracy.

Feeding device
A feeding hopper for free-flowing materials
2. Vibrating feeding hopper for materials that are not easy to flow
3. Star feeder for pouring materials
4. Fluid bulk material feeder: Pneumatic pre-feeder
Components of this machine:
The main components of the system include the feeding hopper, the body of the feeder, the transmission device, the load sensor, the speed sensor, the frequency converter and the weighing calculation instrument. It can be connected to the upper-level DCS system through RS485 serial or fieldbus communication interfaces to achieve DCS control
