CLT/A Vertical Cyclone Dust Separator for Industrial Non-fibrous Dust Removal

Product Introduction

The CLT/A cyclone dust separator is a vertical gas-cyclone centrifugal dust collector engineered to capture non-fibrous dust with moisture content no more than 4%. As a widely used Dust Collector Filter pre-stage separator, this cyclone unit can work with matched Air compressor filter to purify compressed air supply for auxiliary ash cleaning and pipeline inspection systems. It is a proven dust control solution for metallurgy, casting, sandblasting, chemical processing, construction materials and refractory material manufacturing. This model is divided into Y type and X type based on its installation position in the ventilation system. The Y type is the press-in type, installed after the ventilation fan, while the X type is the suction type, arranged before the fan. To simplify field piping connection, both Y and X versions include N-type and S-type airflow rotation options: N-type inlet airflow rotates counterclockwise, and S-type inlet airflow rotates clockwise. Beyond the single-barrel version, the CLT/A series also supplies double barrel, triple barrel, six-barrel and eight-barrel combined configurations to match different air volume demands on site.

Working Principle

Dust-laden air enters the cyclone chamber tangentially through the downward spiral inlet. The spiral guide plate on the top directs the incoming airflow to form a stable rotary vortex inside the cylinder. The guide plate angle is set between 8° and 20°, and the standard design for CLT/A adopts 15 degrees. This guide plate eliminates small upward eddy currents generated by incoming gas, cutting unnecessary kinetic energy loss and improving overall dust capture efficiency.

Under centrifugal force generated by high-speed rotation, solid dust particles are thrown outward toward the inner wall of the cylinder. After colliding with the wall, particles lose velocity and slide down along the cylinder and cone wall under gravity, finally falling into the ash hopper for collection. The cleaned inner spiral airflow reverses direction at the bottom of the cone, rises upward along the central axis of the cyclone, and discharges out of the top exhaust pipe.

The CLT/A design features a slender cylinder and a relatively long cone with a small taper angle. This structural layout extends the retention time of dust particles inside the cyclone, boosting dust separation efficiency, while the trade-off is a higher pressure loss compared with short-cone cyclone alternatives. Operators can select rotation direction and installation type according to fan layout and workshop space constraints.

Main Technical Parameters

The table below shows the air handling capacity of CLT/A series models at a standard inlet velocity of 18 m/s.

Core Advantages

Flexible installation and rotation options

The CLT/A series provides two installation types: Y press-in and X suction style. N counterclockwise and S clockwise rotation directions can be chosen freely to match existing ventilation fan positions and pipeline routing. Multiple combined barrel versions (double, triple, six, eight barrels) are available to scale up air processing capacity without redesigning the whole dedusting system. It is easy to integrate into existing ventilation systems for plant renovation projects.

Optimized spiral guide plate design

The built-in spiral top guide plate suppresses upward small eddy currents, reducing energy waste and improving dust separation efficiency. The 15° standard angle strikes a stable balance between pressure drop and dust removal performance, and we can adjust the guide angle for custom requirements if customers prioritize lower resistance or higher efficiency.

High adaptability for dry non-fibrous dust

It works reliably for dry non-fibrous dust with moisture content ≤4%. It handles mineral dust, sand blasting grit, casting powder, refractory dust and building material dust perfectly. It is widely used as a low-cost primary separator to take most coarse dust load before fine filtration equipment, extending the service life of downstream Dust Collector Filter bags or cartridges.

Simple structure, easy maintenance

The cyclone adopts all-metal welded structure, no internal filter consumables. There is no filter element to replace frequently. The main routine work is regular ash discharge from the bottom hopper. It can run continuously for long hours under dry working conditions, greatly lowering long-term operation and spare parts cost compared with high-consumption filter equipment.

Modular combination design

Users can select multi-barrel assemblies according to actual air volume. Multiple cyclone units work in parallel, each maintaining independent airflow field. If one single barrel needs inspection, the rest can keep running, which minimizes production downtime.

Application Scenarios

The CLT/A vertical cyclone dust separator is widely applied for dry non-fibrous dust treatment in the following industries:

Metallurgy: Ore crushing, screening, sintering workshop coarse dust pre-separation

Foundry industry: Sand casting, shakeout, sandblasting workshop dust removal

Chemical industry: Dry powder production, mineral raw material grinding exhaust

Building materials & refractory: Cement powder, lime, refractory material processing dust collection

Other workshops: Abrasive blasting, stone processing, dry powder mixing lines

It is mostly used as the first stage of two-stage dedusting systems. After CLT/A separates coarse particles, the gas flows into a Dust Collector Filter for fine dust capture to meet strict emission standards. If the ash hopper uses pneumatic automatic ash discharge valves, the compressed air pipeline needs to be equipped with an Air compressor filter to remove oil and water, preventing valve blockage and failure.

Installation, Operation and Maintenance

Installation selection

Confirm the fan position first to select Y type (after fan) or X type (before fan). Choose N or S rotation direction to fit your pipe layout. Keep the cyclone vertically installed; tilt will break the internal vortex and sharply reduce dust removal efficiency. All flange joints must be sealed tightly to avoid air leakage.

Start-up inspection

Check the inlet and outlet pipeline, ash hopper and ash discharge valve before starting the ventilation fan. Ensure the ash discharge port is sealed well. Air leakage at the bottom will destroy the vortex and cause re-entrainment of separated dust back into the clean air flow.

Operating parameters control

Keep inlet airflow speed close to the design value of 18 m/s. Too low velocity leads to poor centrifugal separation; excessive velocity brings sharp resistance rise and higher fan power consumption. Do not feed dust with moisture higher than 4%, as sticky wet dust will adhere to the inner cone wall and block the cyclone.

Regular ash cleaning

Empty the ash hopper on a fixed schedule. Overstocked ash will interfere with the vortex field and reduce separation efficiency. For pneumatic ash discharge structures, maintain the Air compressor filter regularly to guarantee clean, dry compressed air for actuators.

Routine inspection

Check the inner cylinder wall for abrasion regularly. For highly abrasive dust, wear-resistant coating can be added on the inner surface. If deformation or weld damage appears, repair it in time to avoid airflow disorder.

FAQ

Q1: What kind of dust is not suitable for CLT/A cyclone dust separator?

A: It is designed for non-fibrous dust with moisture ≤4%. It is not suitable for fibrous dust, sticky wet dust, or dust with high moisture content, which will stick to the cone wall and cause blockage.

Q2: What is the difference between Y type and X type CLT/A cyclone?

A: Y type is press-in type, installed after the ventilation fan, positive pressure inside the cyclone. X type is suction type, installed before the fan, working under negative pressure. The pressure loss of X type (1911 Pa) is higher than Y type (1705 Pa).

Q3: Can this cyclone reach emission standard alone?

A: It is a coarse dust separator. It can capture large and medium particles efficiently, but fine dust below 10μm cannot be fully removed. It is normally used as pre-filter before a Dust Collector Filter for two-stage purification.

Q4: Do I need an Air compressor filter for this cyclone?

A: The cyclone itself does not need compressed air for jet cleaning. If you adopt pneumatic ash discharge valves, the compressed air supply line must install an Air compressor filter to remove oil and water and protect the valve.

Q5: How many barrels should I choose for my project?

A: Confirm the total air volume of your ventilation system first. Check the technical table to select single or multiple parallel barrels. We can customize combined multi-barrel assemblies to match your required airflow.
