1. Description of sand cyclone:
Sand cyclone widely applied in mine chosen technique in various metal mines as the following works:
1). Classification for section I closed circuit grinding
2). Classification for section II closed circuit grinding
3). Regrinding for fine mine classification
4). Mud-removing before selection and after selection
5). Dam and backfill for gangue
In closed circuit grinding system, it features high classification efficiency and fine overfall fineness under high mine concentration.
Classification efficiency is higher for 5-10% than common screw grader. It benefits for enhancing grader utilizing coefficient.
2. Working principle of sand cyclone:
A typical hydrocyclone consists of a conically shaped vessel, open at its apex, or underflow, joined to a cylindrical section, which has a tangential feed inlet.The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe.The feed is introduced under the pressure through the tangential entry which imparts swirling motion to the pulp.This generates a vortex in the cyclone. The light granules will be pulled out by a pump through the overflow pipe, while the heavy particles will be discharged with the pulp through the underflow discharge.
3. Technical Specification of sand cyclone:
4. Features of sand cyclone:
1)Simple structure, light and flexible, no moving parts;
2)Low equipment cost, easy disassembly, maintenance, less the cost of infrastructure
3)Large handling capacity, Can handle the small particle size to about 10μm
4)High efficient classification.
5)Slurry in the cyclone retention volume and time very small, easy to deal with when the machine stops.
6)Long service life, large disposal capability, small land covering, no driving power consumption.
7)High efficient grading & de-sliming equipment of fine -particle material.
5. Application Area:
1). Gas / Fume filtration for industrial boiler .
2). Metallurgy Furnace fumes filtration
3). Woodworking plant
4). Machine processing plant
5). Powder processing plant
6). cement production process
