Jinsheng Mist Forest-High Pressure Mist System is one of the leading manufacturers and suppliers of automated dust control unit in China. If you're going to wholesale cheap automated dust control unit made in China, welcome to get free sample from our factory. All customized products are with high quality and low price.
The Automated Dust Control Unit is a packaged high-pressure misting system for localized dust suppression at material processing, handling, and transfer points. Filtered water is pressurized to 50–70 bar and discharged through fine-atomizing nozzles that produce typical droplets of 5–15 μm.
The unit combines the high-pressure pump, water filtration, pressure regulation, control valves, piping connections, and atomizing nozzles. Pump capacity, nozzle quantity, piping layout, control zones, and operating sequence are selected from the dust source, equipment layout, water supply, and required treatment area.

The 50–70 bar pressure range and 5–15 μm typical droplet range provide the base operating conditions for nozzle and system selection. Final configuration is determined from the actual installation requirements.
How the Unit Controls Dust
Fine Atomization: High-pressure water passes through fine-atomizing nozzles to form droplets typically measuring 5–15 μm. The mist is directed toward the dust-generation area rather than distributed across unrelated sections of the site.
Source-Level Application: Nozzles are positioned around specific emission points such as crusher discharge areas, screening sections, conveyor transfers, and material loading points. Placement follows the material flow and equipment geometry.
Controlled Mist Output: Pressure regulation and zone control allow the misting system to match the operating area. Different nozzle groups can be assigned to separate zones when several dust sources operate at different times.
Application Areas
Crushing and Screening
Misting points can be arranged around crushers, screens, discharge areas, and material transfer sections where impact and material movement generate airborne dust.
Conveyors and Transfer Points
Nozzles can be positioned near conveyor discharge points, transfer chutes, and material drop locations. The piping layout follows the conveyor structure and selected treatment points.
Loading and Unloading
Loading stations, unloading areas, and material transfer positions can use localized misting where dust is generated during material movement.
Industrial Processing
The unit can be configured for selected dust-generation points in quarrying, mineral processing, aggregate handling, construction, and other industrial material-handling operations.
System Selection
Dust Source: Identify each dust-generating point before selecting the equipment. Material flow, drop height, equipment position, enclosure structure, and surrounding airflow affect nozzle placement.
Water Supply: Confirm the available water source, inlet pressure, flow conditions, and water quality. Filtration requirements should be considered before final pump and nozzle selection.
Treatment Area: Define the actual area requiring mist coverage rather than using the total site area. The distance between the equipment and nozzle positions helps determine piping routes and nozzle distribution.
Operating Pattern: Production schedules determine how control zones should be arranged. Dust sources with different operating periods can be assigned to separate zones.
Automation and Control
Scheduled Operation
Programmable control allows selected misting zones to operate according to defined schedules. This supports consistent operation during planned production periods.
Zone Management
A multi-zone arrangement separates nozzle groups according to their dust sources. Each zone can be controlled according to the corresponding equipment or process area.
Process Coordination
The control sequence can be matched to the operating requirements of the application. This allows misting activity to follow defined production or material-handling conditions.
Manufacturing and Inspection
Component Fabrication: Equipment structures and supporting parts can involve cutting, bending, stamping, welding, and CNC machining according to the selected configuration.
System Assembly: The pump, filtration assembly, pressure-regulation components, valves, piping connections, and atomizing nozzles are assembled as one coordinated system. Component positions and connection points are checked during assembly.
Functional Testing: The completed unit is tested before shipment. Pressure-related connections, water flow paths, control functions, and system operation are checked against the configured requirements.
Configuration and Project Supply
Standard Configuration
Core components can be combined according to the required pressure range, pumping arrangement, filtration, nozzle configuration, and control method.
Custom Configuration
Pump capacity, nozzle quantity, piping arrangement, control zones, equipment dimensions, and electrical requirements can be adjusted to suit the installation layout.
System Integration
The unit can be supplied with the required high-pressure piping and atomizing nozzles. The final arrangement follows the dust-source locations, equipment positions, and available installation space.
What to Specify for an Inquiry
Process Information
Provide the material being handled, equipment type, dust-source locations, and operating conditions. This establishes the basis for nozzle positioning and zone selection.
Site Information
A site drawing or equipment layout should include the approximate treatment area, equipment dimensions, nozzle installation positions, water source, and available electrical supply.
Operating Requirements
Specify the expected operating schedule, number of dust-control areas, preferred control arrangement, and any process conditions that affect misting operation.
Providing these details allows pump selection, nozzle distribution, piping routes, filtration, and control zones to be evaluated as one system.
FAQ
Q: What operating pressure does the unit use?
A: The typical operating pressure is 50–70 bar. Final operating conditions depend on the selected pump, nozzle arrangement, and project configuration.
Q: What droplet size does the system produce?
A: Typical droplets are 5–15 μm under the specified operating conditions. Actual droplet characteristics depend on pressure and nozzle configuration.
Q: Can one unit serve several dust points?
A: Yes. Multiple dust sources can be arranged as separate control zones, with each zone connected to its designated nozzle group.
Q: Can the system operate automatically?
A: Yes. Programmable control can be configured for scheduled operation and defined zone sequences.
Q: What determines the number of nozzles?
A: Nozzle quantity is selected from the dust-source locations, required treatment area, operating pressure, nozzle arrangement, and site layout.
Q: What information is needed for system selection?
A: The main inputs are dust-source locations, process layout, treatment area, water supply, electrical supply, operating schedule, and control requirements.
