DF- PSM Ultrasonic Particle Size Analyzer

DF- PSM Ultrasonic Particle Size Analyzer

I. Product Overview
DF- PSM Ultrasonic Particle Size Monitor (PSM) is an inline instrument measures size of particle within slurry. Particle Size Analysis Pdf can provide accurate and real-time analysis of particle size, PSM is applied to measure particle size distribution from 25 mm to 295 mm with P80 standard. By using the feedback information of PSM, grinding circuit optimization, product quality improvement, recovery rate improvement and energy consumption reduction can be achieved.

II. Operating Principle
PSM inhales relatively stable and representative slurry stream by generating vacuum space through sample conditioning unit, then Particle Size Analysis Methods conduct degassing procedure. Slurry after degassing flow through the ultrasonic attenuation measuring unit (ultrasonic transducer) for measurement, finally, the slurry sample flow back to original process. During measuring period, the Particle Size Analyzer Principle detector emits ultrasonic pulse with multiple frequencies to penetrate the sample, and receive several attenuation parameters from the ultrasonic pulses. Those parameters are directly related to the particle size distribution within slurry. The parameters will be considered as variables in each size fraction to calculate the concentration and particle size of slurry.

III. Product Features

· High measuring accuracy
The change of ultrasonic attenuation in slurry is the result of interaction of all solid particles. Instead of interpolation method, PSM directly measures ultrasonic attenuation, the ultrasonic attenuation resolution is up to 0.1dB. Meanwhile, PSM uses air separation technology to eliminate the influence of bubbles in the slurry and ensures better measurement accuracy.

· Application of multiple fraction and multi-stream
PSM can analyze up to 5 slurry particle size distributions at the same time, and provides concentration detection without extra expenses. The signal processing technology with large dynamic range enables PSM not only provides 3 channels of slurry particle size detection but also suitable for different processes with different slurry natures. PSM can perfectly fulfill particle size requirements at overflow of primary, secondary and tertiary grinding process.

· Representative samples
Abundant field application experience ensures representativeness and negotiability of sampling. Different sampling methods such as reduction sampler, pipe sampler, etc. are adopted. Samplers are the designing result of constant improvement on the basis of abundant practical experience, not only practicable and reliable, but also posses with long period wear resistance.

· Participate in closed-loop control for better effect
The measurement of PSM is fast, consistent and representative. It makes closed-loop control of grinding automation system possible, so as to improve the mill capacity under the condition of satisfying the Particle Size Analyzer For Nanoparticles requirement and bring substantial economic benefits.
