In the process of measuring land area such as mining area, real estate, cadastre, and so on, the requirement for measurement accuracy is quite high. When the deformation of the measured land projection exceeds the relevant standard, the following methods can be used according to different requirements. The calculation of the area for land measurement, the calculation of the surface area of ​​the ellipsoid, the Gaussian projection coordinate system, and the area correction calculation method. Or, in order to be more convenient and quick, the farmland area measuring instrument is directly selected, so that unnecessary errors and troubles can be avoided.
For different measurement methods, some of their characteristics are also found in long-term applications. The Gaussian projection's own characteristics determine that the area of ​​the measured land projected to the Gaussian plane will be deformed. The use of different Gaussian projection coordinate systems for the calculation of the land area, the calculation results will be different. In the calculation of a large area of ​​land area measurements, the use of ellipsoid surface area calculations is more appropriate. For the common measurement of land area calculations, in order to obtain the measurement results of the measured land area in accordance with the actual plane, it is necessary to use the above-mentioned several calculation methods that can reduce the projection distortion, and the method is suitable for those lands with small spans. This method is simple and practical, and does not require the complicated calculation process of a Gaussian projection. Each measurement method has its advantages and disadvantages. Therefore, the application area of ​​the farmland area measuring instrument is more worthy of recognition, and the resulting errors are small and even negligible.
High Speed Wet Material Mixing Granulator
The high efficiency wet type mixing granulator used for wet granule preparation of tablets, capsules, granules, etc. It is widely used in such industries as medicine, food, chemical industry, etc.
Working principle:
Under the mixing action of the mixing paddle in the vessel, the powder materials are under the semi-flowing status and are mixed thoroughly. Then the bonds (Chinese patent medicine liquid extracts or other fluids) are injected to turn them into wet soft materials, which will be cut into even wet granules by the granule sizing paddle (granulating knife).
Features:
â—The machine adopts inverted taper granulating integral pot technology. The special mixing paddle and cutting knife structure ensures even finished products.
â—Mixing and granulating are completed in the closed pot to reduce dust pollution, conforming to GMP requirements.
â—With simple and safe operation, the mixing and granulating procedures are completed in one step.
â—It adopts human-machine interface PLC control, and the motor is subject to variable frequency speed adjustment. All process parameters can be stored automatically.
â—It is provided with the steam and water conversion function, so that cleaning is ensured.
Options:
â—Lifting machine feeding
â—Vacuum feeding
â—Material pot jacket design, used for heating and cooling
â—Equipped with wet type granule sizing machine or oscillating granulator
â—Bond liquid supply metering system
â—Data online printing system
