Product catalog summary

Product Overview
The DF-PSM Ultrasonic Particle Size Monitor is an inline instrument designed to measure particle size within slurry, providing accurate and real-time analysis. It measures particle size distribution from 25 mm to 295 mm using the P80 standard, aiding in grinding circuit optimization, product quality improvement, recovery rate enhancement, and energy consumption reduction.

Operating Principle
The PSM operates by inhaling a stable slurry stream, conducting a degassing procedure, and measuring ultrasonic attenuation. The ultrasonic transducer emits pulses at multiple frequencies, and the attenuation parameters received are used to calculate particle size distribution and concentration.

Product Features

High Measuring Accuracy: Direct measurement of ultrasonic attenuation with a resolution of 0.1dB, using air separation technology to eliminate bubble influence.
Multi-fraction and Multi-stream Application: Capable of analyzing up to 5 slurry particle size distributions simultaneously, suitable for various processes.
Representative Samples: Utilizes different sampling methods to ensure representativeness and reliability.
Closed-loop Control: Enables fast and consistent measurements for improved mill capacity and economic benefits.

Technical Parameters

Operating Mode: Multi-frequency ultrasonic attenuation measurement.
Measuring Media: Suitable for various slurry types including iron, molybdenum, copper, lead-zinc, and slag slurry.
Performance: Measures particle size under 1mm with a typical precision of absolute error < 1.0%.
Output: Provides analog output and optional PROFIBUS communication.
Installation and Site Conditions: Requires specific space, water, and gas supply conditions.
Design: Made from polymer or mild steel encapsulated with rubber, with IP55 protection level.
Display & Control: Features an industrial HMI with real-time data display and various control functions.

Product Applications
The PSM is applicable in the grinding processes of non-ferrous and ferrous metals, including iron ore, gold, copper, molybdenum, lead-zinc, coal cinder, and other non-metal mineral processing. It is used for particle size measurement at cyclone overflow in processing plants.
