A cyclone dust collector is a machine that proves to be a working method in collecting t the dust and debris that is created by machining in works like planning and jointing. The collector is technically an advanced mechanism as it consists of two collection points, one for dirt and the other for debris.

How does a cyclone dust collector operate?

A cyclone dust collector uses centrifugal force to separate the particles. The flow of air works in a downward spiral or centrifugal vortex on entering the dust collector and this forces the larger particles to move into the first collector while the finer dust particles move into the second collector.

Advantages of a cyclone dust collector:

• A cyclone dust collector reduces the amount of dust and makes the work of removal and cleaning of industrial dust easier. A cyclone dust collector reduces the larger, coarser dust which reduces the pressure on filters.

• Baghouses and cartridge collectors are extremely expensive to maintain whereas the overall maintenance of a dust collector is cost-effective.  The only maintenance required is to empty and replace the dust collecting bin. Many factories install a cyclone dust collector before a baghouse or cartridge collector to extend the bag life.

• A baghouse or cartridge dust collector does not allow recovery of the product as the material gets lost in the filters. A cyclone dust collector does not require any filters and all the recovered material gets removed through the dust discharge valve.

• Bag houses and cartridge dust collectors are not well suited for fibrous, sticky or hygroscopic dust. Cyclone dust collectors are efficient in preventing these materials from reaching the filters. A cyclone dust collector can be fitted in front of a bag house or cartridge dust collector to save the money and time that would be wasted in repairing or replacing a filter.

• INERTIAL SEPARATORS– They separate dust from gas streams using centrifugal, gravitational and inertial force. The separated dust is collected in hoppers and stored temporarily. The three main types of inertial dust collectors are Settling Chambers, Baffle Chambers and Centrifugal Collectors. The most common type of centrifugal or inertial dust collectors in use nowadays are Single Cyclone Separators, Multiple Cyclone Separators and Secondary Air Flow Separators.
• FABRIC FILTERS– Fabric filters are also known as baghouses. They are mainly used to separate dust particle from dusty gases. They are efficient and as cost-effective on the other hand. The most common types of fabric filters are Shaking, Reverse Air, Pulse Jet, Sonic and   Cartridge Collectors. The parts used in fabric filters are clean plenum, dusty plenum, bag assembly, tube-plate, Rave/screw, compressed air header, blowpipe and housing and hopper.
• WET SCRUBBERS– Wet scrubbers are normally dust collectors but they use the liquid in the process of dust collection. The scrubbing liquid mixes with the gas stream containing the dust. This contact separates the dust from the gas stream. There are three main types of wet scrubbers, Gas Humidification, Gas-Liquid Contact and Gas-Liquid Separation.
• ELECTROSTATIC PRECIPITATORS– They use electrostatic force to separate dust particles from exhaust gases. There are two main types of electrostatic precipitator, High Voltage, single-stage and Low Voltage, two-stage. Plate Precipitators and Tubular Precipitators are the two common types of electrostatic precipitators.
• UNIT COLLECTORS– The unit collectors control contamination at the very beginning. Unit collectors are small and consist of a fan and a kind of dust collector. There are two main types of unit collectors. One is the Fabric collector with a manual shaking or pulse jet cleaning that is normally used for the fine dust. The other is Cyclone collectors-normally used for coarse dust.
