  • The professional Bucket Wheel Excavator manufacturerThe professional Bucket Wheel Excavator...

      Bucket wheel excavator is an important mining equipment for large project of great amount of mining and long service, especially suitable for open pit, large earthworks and other applications. The equipment is important during continuous mining process of mining, transportation and casting. Bucket wheel excavator can run continuously with high efficiency and low consumption. Stripping rock by bucket wheel excavator does not need drilling, blasting and other processes, meanwhile, effectively reduces the emission of harmful substances. Bucket wheel excavators can also be used for the mine of good occurrence condition and softer structure.
      According to the equipment structure and rated productivity, bucket wheel excavator can be divided into unloading bridges / large mining; unloading cantilever / compact mining; unloading bridges / giant mining.
      Our company provides all series of bucket wheel excavators in standard or long type, powered by diesel engine or electricity. Non- standard design is also available based on user's requirements.

    • Screw conveyoScrew conveyo

        Screw conveyor is a kind of machinery with motor to drive screw rotation and to push the material in order to achieve the delivery. It can complete horizontal, inclined or vertical transportation, with the advantages of simple structure, small cross-sectional area, good sealing, easy operation and maintenance, convenient to seal and transport and so on. According to the transportation form, Screw conveyor is divided into shaft screw conveyor and shaftless screw conveyor, meanwhile, according to the appearance is divided into U-screw conveyor and tubular screw conveyor. Screw conveyor is widely used in food industry, building materials industry, chemical industry, machinery manufacturing, transportation and other sectors of the national economy.
        Shenyang Juli Mechanical Design Co., Ltd. adopts advanced technology, such as non-equal-pitch helix axis blades and the gradual transition from the beginning to the end of the blade. The blade is made from high wear-resistant, corrosion-resistant materials, with features of smooth feeding, high strength, good anti-abrasion, etc. The thickness of the spiral blade can be increased to enhance blade strength and extend the service life. Adding knockout angle steel in the center of the outlet makes the material flowing more fluid and improves the stress state of the blade to prevent the blade from open welding or bending on the tip, to avoid the opposite blade’s breakage due to fatigue failure and make sure the coal column level is basically uniform decline without blocking.
        Shenyang Juli Mechanical Design Co., Ltd. has the supply of 6m coke oven supporting spiral feeder, 7m coke oven supporting spiral feeder and 7.63 m coke oven supporting spiral feeder, as well as offering customized services.

      • Intelligent system for detecting tooth decay using piezo vibration and 100 accuracyIntelligent system for detecting tooth decay...

          Always Special attention has been paid to the accurate diagnosis of dental caries in dentistry.
          To detect dental caries At the occlusal levels via The perfect mirror And at interdental levels The use of radiographs of Bytewing .
          addition to the cost of Preparing radiographs , It expands the patient to x-rays, which itself has multiple complications.
          Different radiographic systems are one of the main diagnostic tools in dentistry.
          As a result of an increase in the number of illnesses resulting from laser imaging that is the result of this radiation , And the increase in radiation damage to humans.
          The best way to detect with 100% accuracy And without zero percentages, To improve the quality of decay detection and Renounce all the problems listed , Decided to design got this device.

          The complications and problems of radiographic systems:

          **Diseases of the skin and cancer caused by x-rays for dentists and patients
          **Physical complications for pregnant women in embryos
          **High cost in the preparation and maintenance of radiographic equipment
          **Lack of accurate diagnosis of decay (detection of up to 60%) Or the separation of amalgam from the tooth (detecting up to 25%) in the restorative tooth By radiography devices
          **Detection of decay (detection 0%) or separation of amalgam substance from the tooth in restorative tooth by oral sensors

          ** Specific objectives of the project

          1. Record the waves from healthy teeth
          2. Record the waves from the teeth with 0.5 mm cavities
          3. Record waves from teeth with 1 mm cavities
          4. Record waves from 1.5 mm cavities
          5. Record waves from teeth with 2 mm cavities
          6. Compare the two primitive groups together
          7. Record radiographs of sample teeth
          8. Review the synchronization of radiographic images with the designed model

          ** Applied Schemes

          • Possibility of examining tooth decay in pregnant women and the elderly
          • Facilitating the examination of dental caries and studying the separation of amalgam from the tooth in restored teeth ,dont need to go to radiographic centers And exposure to laser radiation (Notably, the most advanced X-ray devices are not able to do it)
          • High accuracy of detection than radiography devices up to 100% accuracy of detection
          • Cheaper prices, so all dentists will be able to buy this device
          • Because of its low cost of service, it does not cost much, and it's a welfare for patients
          • Avoiding time to go to the radiography clinic and returning to the dentist's office.

          Teeth are randomly divided into 5 groups of 20 teeth. In groups 1-4, cavities at 0.5, 1, 1.5 and 2 depths in the teeth will be created as a decay model. In the fifth group, no cavity will be created. By contacting the ultrasonic probe with the teeth, the waves received by the detector will be recorded.

          The next steps are as follows:
          1- 3D modeling of the device in Solidworkes 2016 Software
          2. Load dynamic forces and dynamic analysis with MC Adams software
          3. The loading forces of motion and vibration analysis software ANSYS 17.1
          4. Vibration testing of teeth with ME Scope software for comparison with modeling analysis
          Next step The teeth are parallel radiographs and the result will be compared with the model. Statistical analysis of data By one-agent variance analysis and The appropriate follow-up is used to compare two-dimensional groups in groups.

          At this point, our data will be ready for the device library And the device becomes the program.

          The cost of the Intelligent system for detecting tooth decay using piezo vibration and 100% accuracy:

          **Making the original model Body with a beautiful look:2500$
          **Modal and harmonic vibration testing on 200 human tooth samples ( We will receive from the bank of dentistry of medicin university):19000$
          **Build a humanoid robot to move and sit on a dental unit To view system performance :4000$
