In-line Neutron Activation Cement Element Analyzer Dandong Dongfang Measurement & Control Technology Co.,Ltd

公司简介 Company Profile Established in 1996, Dandong Dongfang Measurement & Control Co., Ltd. features the largest company specialized in mine automation in China with the highest market share. In addition, it is Product Overview DF-5701 in-line neutron activation cement element analyzer (Fig. 1-1) features one cross-belt type in-line detecting device for cement materials. It is used for in-line detection of element components also the biggest inline industrial detection instrument manufacturer in Asia and one leading during material pile management and raw meal batching. enterprise in National...

Product Structure DF- 5701 in- line neutron activation cement element analyzer consists of five parts: measuring unit, neutron source, detector, signal processing cabinet and main unit. (Fig. 1-2) The detector is mounted at the top of the measuring unit and also over the material conveying belt, which is used to receive rays emitted by materials acted by neutrons. There are ray suppressor and heat thermostatic part outside the detector, of which, the ray suppressor is used to restrain and interfere rays, while thermostatic part is to keep the detector under constant temperature. 4. Signal processing...

Operating Principle Technical Parameters DF- 5701 adopts prompt gamma neutron activation analysis (PGNAA) technology. The neutron source emits rapid neutrons with average energy at 2.35Mev, which are then degraded into thermal neutrons by the measuring unit. The thermal neutrons radiate cement materials, so that Angle of supporting tank Neutron source Operation temperature Power source Site data to the main unit Fiber optic communication is adopted Measuring principle Prompt gamma neutron activation analysis (PGNAA) technology Analysis time Oxide for standard analyzing Quality parameters to be...

the steel core belt or belt containing chlorine, but a very small amount of wire does not Product Application significantly affect the performance of the analyzer. Curing method is recommended for belt DF- 5701 is mainly used for material pile management and raw meal batching in cement plants. connector, so as to prevent damage of the DF-5701 supporting tank. Material pile management function is realized according to real- time detection information Belt load will affect the performance of the analyzer, and therefore it is also one of the important conducted by the analyzer on raw materials,...

Figure 5-3 Process Control under Automatic Mode Material pile management system functions ◆ Provide material composition and quality needed for meeting material pile quality target. Fig. 4 Process Control under Manual Mode ◆ When there are many feasible batching program, choose the batching program at the lowest cost. ◆ The user can set the priority of quality control target to implement the most appropriate batching scheme needed by the user. ◆ Provide the composition of each material pile for quality evaluation. Automatic mode In automatic mode, process control software is used for the situation...

Main content of raw meal batching system ◆ Need no separate clay and limestone homogenization stockyard ◆ Cancel the sampling system ◆ The composition of raw materials (chemical analysis) ◆ Target value of quality control parameters (KH, n, p and so on) ◆ The composition of mixing material (to be determined by DF-5701) For the original plant running ◆ Need no sampling testing, thus reducing laboratory cost ◆ Make mining more rationalized ◆ Reduce fluctuations in the premixing material composition ◆ Improve the quality of the premixing material ◆ Maximize the use of low-quality mine resources...

Product Characteristics Comprehensiveness: representativeness; Fastness: Giving composition data once per minute; Effectiveness: Providing key parameter data for production, so as to make effective control; Stability: Dual- loop temperature control, automatic stability spectrum, and long-term stable operation; Safety: More effective shielding body. Radiation dose around the device is lower than similar products abroad. The most fundamental feature of DF-5701 is that it provides a kind of in-line detection means of element composition in the materials on the belt. Compared with other detection...
