ExploreFilter bag, cyclone and air handling equipment solutions for dust from raw material preparation, pressing, glaze preparation, drying and kiln areas.

Filter bag, cyclone and air handling equipment solutions for dust from raw material preparation, pressing, glaze preparation, drying and kiln areas. Dust loading at the process points, operating temperature, maintenance access and emission target determine the product selection.
In ceramics and porcelain production, raw material preparation, spray dryers, presses, glazing, kilns, and finishing lines generate fine mineral dust and hot gas. Cyclones, baghouse filters, air handling equipment, filter bags/cages, and material transfer systems are selected on a process-by-process basis.

The filter housing, fan, ductwork, filter element, pulse-jet system and discharge/conveying equipment are not independent of one another; they are evaluated as components of the same operating point.
| Process Dew Point | Filter / dust-fume solution | Fan, ductwork and conveying equipment | Critical selection grade |
|---|---|---|---|
| Raw material crushing/grinding | Cyclone + baghouse filter | Mill fan equipment, rotary valve, and conveyor | Silica/mineral dust and wear |
| Spray dryer | Heavy-duty cyclone + suitable final filter | Dryer ID fan and hot gas duct | Damp fine dust, temperature, and product recovery |
| Press and granule feeding | Local dust collection | Press extraction air handling equipment, elevator, and enclosed transfer | Fine granules, vibration, and leakage |
| Glaze preparation/spraying | Wet/dry-suitable extraction and filtration | Exhaust fan equipment, damper, and duct | Pigment, humidity, and sticky aerosol |
| Kiln/finishing | Hot gas/dust filter and grinding extraction | Kiln exhaust air handling equipment, expansion joint, and local air handling equipment | High temperature, chemical gas, and fine silica |
Maintains the flow/pressure balance of the drying circuit.
Operates on the grinding and product separation line.
Local extraction around granule feeding and the press.
Manages hot gas and process ventilation.
For abrasive fine ceramic dust.
Reduces spray dryer/crushing load.
Based on temperature, humidity, and pigment.
For dryer/kiln lines.
Enclosed transfer of granules/dust.
Dust control at the welding source.
Exact capacity is not set by a catalog name; it is determined by process flow rate, system pressure, temperature, material/dust behavior and discharge continuity.
| technical data | Required site / process information | Impact on selection |
|---|---|---|
| Mineral/dust | Silica, clay, feldspar, pigment, and particle size distribution | Determines wear/media requirements. |
| Temperature/moisture | Spray dryer and kiln conditions | Determines filter bag and condensation risk. |
| Flow rate | Dryer, press, and local extraction points | Determines the air handling equipment/filter. |
| Product recovery | Cyclone/filter product quality | Affects separation design. |
| Conveying | Granule elevator, rotary valve, and conveyor | Affects breakage and continuity. |
These are not success percentages; they are risks that must be verified on site to select the right filter, fan and auxiliary equipment.
