We are offering informatization rotor weigh feeder for cement industry. features: 1. Be applied for dynamically and continuously feeding and measuring the jet-like material or non jet-like material and powdery material. 2. The feeder integrates feeding with weighing, adjusting and conveying. 3. Feed-forward control, high accuracy and low fluctuation. 4. It can not only eliminate the differential pressure caused by pneumatic transmission and material feeding, but also transmit the coal from coal bunker to bunker. It is a feeding control device integrating quantitative feeding with conveying with high accuracy. 5. Permanent gravimetric weighing operation and reliable operation. Discharge directly from the storage bin without a feeding control device before the rotor weigh feeder. 6. Lower the fluctuation of coal feeding and reduce the excess air so as not to increase co when discharge the gas. 7. Because the rotor weigh feeder and the compress air system are integrated as a whole, so the rotary valve and screw pump are saved. 8. The pressure changes of the compressed air system do not influence the accuracy so the measuring accuracy is high. 9. The rotor weigh feeder structure is compact so as to save space; the building area is small so as to reduce the capital investment. 10. Can bear 1 mpa pressure and is explosion-proof. 11. The whole design is composite structure. It is easy to maintain the rotor. The wear parts can be quickly replaced without special tool and lifting equipment. 12. Adopt special material, service time is extended, maintenance reduced, investment saved and operation rate improved. 13. 32 bit microcomputer is used as the main control device of electronic control part; touch screen is adopted as human-computer interface; frequency converter is mainly used as the control component. All of make our product offer high technology.
We are offering high precision and quality mass flow meter. structure: 1.all bearings inside the feeder are imported and the motor and reducer are the products of sew company; 2.steady flow feeder is mainly used for steady the material flow with structure of three-layer and mixing device to prevent material arching and flushing in the silo and material rocketing out caused by air pressure, the steady flow feeder can make the feeding well-distributed, steady and reliable; 3.the system is inspected by coriolis principle. The instantaneous mass flow of the material is measured. It is the real flow meter different from the chute-type flow meter and impact flow meter and also different from loss-in-weight feeder, rotor weighfeeder and ring-typed balance; 4.steady and accuracy feeding is realized by adopting frequency control of motor speed to ensure high accuracy and quick responses; 5.as a pre-feeding device, steady flow feeder is mainly used in powdery weighing system which requires a certain conveying pressure and higher weighing accuracy (eg. Kiln head and kiln tail of cement plant for coal feeding);6.the pre-feeding instrument can also be rotary vane feeder + electronic flow control valve + air chute in normal pressure. The cost of this system is slightly low and is widely used in fly ash weighing and conveying; working principle: the core part for coriolis powdery flow meter is measuring disc, which is drived by the main axes. The material is flow into the central measuring disc, and then threw out by revolving disc. The material will give a force to the vane of the disc, the force is called coriolis force, the force is proportional to the material of the mass, the material flow rate will be got after measuring the force. In coriolis powdery flow meter, the measured force is torques which caused by the driving axes on measuring disc. Due to the radius of disc is fixed, the coriolis force will be calculated when measuring the torques, at the same time, the material instantaneous flow rate also can be got indirectly. There is no influence on the measurement result for friction between material particles and measuring disc, as well as the friction among the material layer caused by different speed, to ensure the precision of the system. function characteristics: 1. The system adopts the following structure: eb-dac5000 control system, namely plc+touch screen or intelligent instrument. 2. It is a set of system that can realize continuous feeding and weighing. 3. Reasonable structure, convenient maintenance and reliable operation. 4. Automatically measure system zero and calculate calibration factor. 5. Friendly touch screen operating interference makes the operation simple, and the control process and system statue can be displayed on-line. 6. Special parameter table is set to make the system operate in best conditions, and the centralized and local switching can be realized in screen. 7. The system has the display function of shift accumulation, daily accumulation and total accumulation. 8. Torque detection adopts customized dynamic torque sensor 9. The system has the function of self-diagnosis and can be connected to dsc system. 10. The system adopts integrated framework, vertically fix dynamic torque sensor, assemble precision, stable running. parameter: weighing range: 3~160m3 / h weighing accuracy: ±0.5%

We are offering fb screw conveyer for bulk materials handing. Introduction: fb screw feeder is a kind of measuring equipment for feeding control, dynamic measuring and continuous conveying bulk material and powder. It can be widely used in building materials, chemical, coal, ports, ceramics, food, and other industries. The screw feeder has two types:single tube single layer and double tube, double layer. If it is the former, it can realize measurement and conveying at the same time. If it is the latter, the above undertakes steady flow and conveying, and the bottom undertakes measurement and conveying that can have better steady flow effect and save spaces. Besides, the lenghth of the conveyor can be designed according to actual conditions. Working principle: when material is conveyed through screw from inlet to outlet, the material weight can be detected by the lode cell on the electrical weighing device under the conveyor and a signal in proportion to the material weight will be generated and transmitted to the controller. Meanwhile, the speed can be detected by the speed sensor installed on the tail pulley and a signal is also generated and transmitted to the controller. By multiplying the weight signal and the speed signal, the instantaneous flow value and total accumulation can be calculated. The control system compares the actual flow signal with the set flow signal and then regulates the output signal through pid to adjust the feeding speed dynamically and thus to realize the continuous feeding. Product features: 1.fb-dmc-01a intelligent controller is adopted 2.compact structure&steady operation 3.automatically calibrate and measure system zero 4.with the function of self-diagnosis and can be connected to dcs system 5.set all kinds of parameters by hand. 6.gravimetric weighing combined with screw convey to realize continuous dynamic measuring. Parameters: weighing accuracy: ±1% conveying capacity: 1~100t/h
