GTEK Hydrocyclone Description. Hydrocyclone is a continuous device that utilizes centrifugal force to accelerate the settling rate of particles. When feed slurry enters the hydrocyclone tangentially under pressure, as result of the high centrifugal forces, particles coarser than the "cut point" size migrate into a primary vortex adjacent to the wall and move forward to discharge with a small .

to as the cut point. The d50c is the particle size diameter for which 50% by mass reports to the underflow. Solids progressively larger than d50c size have a probability greater than 50% of reporting to the underflow. The ALSI HDC Series is an efficient cyclone, improving separation and reducing short circuiting of fine particles.

ciency curve with a median cut-point at 4.0 µm. When performing respirable dust sampling with cyclones, it is important to adjust the flow rate to give the closest possible match over the whole curve (not just at a single point). The ACGIH/ISO/CEN curve requires using the flow rate that minimizes the bias of the cyclone separation from this curve.
