CyLas

HYDROCYCLONE UNDERFLOW FLARE MEASUREMENT

Overview

The hydrocyclone classifier forms an integral part of the milling circuit. The overall performance of the milling circuit depends directly on the performance of the hydrocyclone classifier. Plant operators have traditionally used the shape of the hydrocyclone underflow to assess the overall efficiency of the milling circuit – the CyLas provides this information on-line.

Principle of operation

CyLas, a product from Mintek, is an online instrument measuring the hydrocyclone underfow discharge angle.  It uses a laser device to measure the distance from a fixed point (where it is mounted) to a point on the hydrocyclone underflow discharge. The distance is then related to the underflow discharge angle with the aid of trigonometric manipulations. Because of its non-contact nature and rugged construction, the CyLas is an inherently low-maintenance instrument.
