01Aggregate dosage system
|1.Stable performance sensor: weighing unit is equipped with high sensible stainless steel pressure sensor. Compared with traditional pull sensor, it is more stable and the signal of it is more stable with lower failure rate.|
2.Accurate batching scale: The batching scale is equipped with rear-drive and it is more accurate, compared with front-drive. The working face on the belt is loose selvage, which reduce the influence the belt tension has on the weighing transducer, ensure the weighing signal is more stable.
3.Flexible and accurate compensation way: belt weighing unit consisting of frequency speed adjustment and a dedicated optical encoder tachometer and flexible and accurate measuring compensation way are applied, whose measuring compensation is more timely and flexible, compared with the performance of conventional slipping speed regulating volume measurement. Accurate compensation makes the aggregate batching is more precise. And the trouble diagnosis alarm on ready can maintain the safe and continuous production of the entire equipment.
4.More practical conveying belt: Brush belt is used , avoiding the influence the guard board have on weighing transducer, ensuring the data of transducer is more real and efficient as well as the calculation and measurement is more precise.
5.Professional qualification authentication: belt weighing transducer technology qualification issued by bureau of technical supervision has been gained.
6.More Selectable Configuration: For the material with a large amount of mud, the material batching station with arc breaking device is provided to the customers, to ensure smooth material distribution and meet production requirements, also to ensure the quality of the finished products.
02Cement Measuring System
|Green and stable modified-frequency spiral calculation and measurement system: the cement batching system adopts modified frequency spiral calculation and measurement system with national pattern technology. The whole process is closed without pollution and waste. The environment protection performance is better. Meanwhile, precision error can be controlled within ±1%, ensuring stability and accuracy of the measurement.|
03Water Measuring System
|Electromagnetic flow-meter electric regulating metering model has been used, which can be controlled and operated remotely. That is, the operator do not have to run between the control room and host as well as finish the setting and adjustment of water, providing the users with great convenience. Meanwhile, the electromagnetic flow-meter is accurate, quick to response, better ensuring the quality of mixture.|
|The original mandatory lining-absence technology is used. When the material is boiling, interpenetrates and move forward outlet, reducing faults like blade wearing, stuck material, blade scuffing, and the problem to replace the lining. The design of two -outlet makes it easy to clean. The blade material of high strength and high wear resistance significantly extends the lifetime of host.|
1. Lining-absence technology largely increases the wear resistance of mixing agitator tank and maximizes the lifetime of the host.
2. Mixing-agitator tank is 1/4-1/3 longer than similar products, ensuring the uniformity and quality of the material.
3. Insert mixing arm is more easy to replace. Meanwhile, the mixing section is bigger, rising productivity by 10-20%.
4. reducer is equipped with axle-reducer. Compared with spur-gear reducer, it can reduce vibration, ensuring the mixing engine is more stable and reliable. Meantime, the trouble rate is lowered, ensuring the performance of the equipment.
5.Mixer engine shaft end bearing is outside which is not only easy to inspect and maintain, but also avoid tank mud and protect the bearing effectively and significantly raise its stability and life time.
6.Synchronous gear uses canned lubricating oil, effectively rising lubricating efficiency, reducing noise and largely extending the life time of synchronous gear.
NFLG mixing system uses monocoque structure, with self-equipped outriggers on the mixing host, reducing the installation and making the entire equipment simpler and more flexible, easy for installation and removal. Mixer cover is provided with a safety switch to ensure the personal safety of maintenance staff. At the same time, the good maintenance platform and safety facilities are designed on both sides of the mixing tank, reflecting the humanization of operational requirements.
05Finished Product Conveying Structure
|Flat belt is used to convey material by NFGL. Compared with trough-type belt, it took a larger floor space but avoid leakage and belting, which can keep the space clean and meet the environment protection standard. And it is convenient to inspect and repair with a lower fault rate.|
06Electric Control System
|1.Process on the operating platform is clean and humanized. It is easy to operate.|
2.The international famous brand PLC main controller is used, which is reliable. Human-machine interface is equipped with touch-screen developed by MITSUBISHI and industry-controlled computer. It is both feasible to operate on computer and touch-screen, ensuring the reliability and convenience of the system.
3.The international famous brand frequency is used, ensuring the reliability of the system.
4.The system is equipped with trouble self-diagnosis function. The computer will warm for the corresponding trouble when trouble happens, which is good for trouble shooting.
5. The production process can be simulated on computer, which reflect the real production process and the operation isn’t boring anymore.
6.Production formula can be stored on the computer, which is convenient to add, delete, revise, print and set formula.
7. Production logs can be stored on the computer with production report such as production details and production statistics, providing strong support for management, scheduling and monitoring.
8. Mix proportion and other relevant inform can be seen on the computer, which is beneficial for the operation and usage of equipment as well as trouble shooting.
9. The fully closed control house with air conditioner presents a broader view, provides the operator with comfortable working condition and reduces labor intensity.
