Application scope:

DW-BP-9010A  is very suitable for quality process control in large, medium and small cement plants (single and double kilns). It can be used for the analysis of primary and secondary oxides in raw materials (such as limestone, sand, bauxite, magnesite and other minerals);Determination of CaO, SiO2, Al2O3, Fe2O3, MgO, SO3, K2O, Na2O, Cl and other conventional elements in raw materials, clinker and cement.

 

Application in steel industry: measuring: The element Si, Mn, P, S, Cu, A, Ni, Cr, Mo, V, Ti, W and Nb can be determined according to GB/T 223.79-2007.

Application in other industries: Determination of S and P in petroleum, glass, ceramics, non-ferrous metals, mining, chemical industry, quality inspection, etc.

 

Feature:

Highly automated analysis saves time and effort

Suitable for the research and management of raw materials, new materials, products, etc. It only takes about 3 minutes to complete the quantitative analysis of more than a dozen elements in one sample, as the high stability of the instrument fully ensures the automatic analysis.

 

The analysis results can be obtained quickly. After data processing, the quality inspection and specification judgment can be made, which can be applied to the production management analysis (especially bath analysis).

  

Quality control:

Quickly analyze the samples collected from the production line. The analysis result (proportion calculation) is used as the control data of raw material preparation for the feedback, which is used to improve and stabilize the quality

 

Advantage:

Fixed multi-channel spectrometer: It is ingenious in the design of spectroscopic system, the collection and detection technology, and effectively improves the counting rate and stability of the instrument.

 

Intelligent fault detection device: It can monitor the instrument parameters in real time, control and protect the instrument and automatically alarm!

 

Advanced collimation technique: The spectral collimator adopts the advanced design technology of Bruker in Germany to optimize the optical path.

Ultra-short optical path: Using ultra-short optical path, the power of the X-ray tube is reduced, the service life of the X-ray tube is prolonged, and the structure of the cooling system is simplified. Greatly save maintenance costs. 

 

Stable regulating system of air flow density: It adopts American control component. It can automatically control the flow rate and density of air, greatly improves the control accuracy, the stability and repeatability of peak and element content detection.

 

Electrical pulse signal acquisition card: It adopts the international advanced electrical pulse acquisition signal algorithm to eliminate the background noise and interference peak, and improves the reliability and effectiveness of peak position determination accuracy and peak position drift correction.

 

Automatic safety protection device: It effectively protects the X-ray tube and high-voltage power supply.

The Analyzing crystal adopts plane and bent configuration of PET, InSb, Ge, LiF, etc., which ensures the measurement accuracy of each element. For Na and Mg elements, the most high-grade multi-layer crystal, it effectively protects the crystal from moisture.
