Mobile Dust Collectors. How They Work?
Illustration shows JMS-50-MHT – 50m3/s, Mobile, Hybrid Track Dust Collector
-
Air is pulled through the dirty air intake by the Centrifugal Fan
-
Larger dust particles drop through the Drop-Out Box and are separated from the air stream.
-
Dust and fumes are trapped on the filters forming a cake on the surface as air passes through the filter house.
-
Reverse pulse filter cleaning system cleans the filters.
-
Dust particles are discharged from the machine via the augers and rotary valves.
-
The velocity probe monitors air speed and turns the centrifugal fan up, or down to maintain air volume.
-
Clean air exhausts from the machine with a filtration efficiency of 99.99% at 0.067 micron.

Key Features. JMS M-Series Dust Collectors.
Mobility Options. Flexible and Space Efficient.
Track-Mounted
Grydale holds international patents for manufacturing the only self-propelled, track-mounted, mobile dust collector on the market. These units offer full mobility with variable speeds to increase the speed and efficiency of operations. A key feature is that the tracks are hydraulically driven by the diesel engine and operated via remote control. Track mobility allows dust collection units to move and operate alongside dust-generating machinery, reducing the volume of air requiring treatment and improving the efficiency of whole-site operations.
Drag Skid
Dust collectors mounted on a skid base offer a cost-effective option. The skid can be dragged using the four towing points at each end of the machine or moved by crane using the four lifting lugs.
Hydraulic Stepping System
Hydraulic Stepping System can be added to the drag skid base to powers four legs that lift the units up, while a pair of skates move the unit forward or backwards. This movement can be repeated to reach the required distance.
Key Features. Filtration.
Air Intake
JMS M-Series mobile dust collectors offer flexible intake options, which means they can be used for general ventilation and dust extraction at the source. Single air intakes are best suited for large dust loads, while dual and multiple air intakes can extract dust from multiple sources simultaneously. Flexible couplings allow the dust collector inlet to connect effectively to ducting on uneven surfaces.
Filters
Another key feature of the mobile dust collectors range is the high-efficiency filter cartridges, which filter both dust and diesel particulates. Baffle plates distribute air throughout the dust collector, ensuring an even wear of filters. Filter access doors offer easy access to the filters, enabling efficient filter maintenance and maximising machine uptimes.
Filtration Efficiency
Independent, NATA-certified Air Flow Performance and Filtration Testing have been conducted both above and below ground as part of rigorous Performance Verification and Certification processes. The results show a collection efficiency of 99.99% at 0.067 microns.
Centrifugal Fan
JMS M-Series Dust Collectors feature a centrifugal fan optimised for the application’s air flow and pressure requirements. Centrifugal fans offer superior energy efficiency and durability, allowing them to operate in the most corrosive environments.
Variable Frequency Drive & Velocity Probe
One key aspect of JMS M-Series Dust Collectors is the inclusion of a Variable Frequency Drive (VFD) in the standard configuration. The VFD regulates power consumption and air volume, which can reduce power consumption by up to 40%.
Fan Silencer
Exhausted air passes through curved silencers to reduce noise pollution. Units can be supplied with a square-to-round attachment, allowing a vent bag to be attached to the exhaust side if required. Custom exhaust silencers can be designed and manufactured to meet site acoustic requirements.
Filter Maintenance
The filters can be easily accessed through the filter access doors, allowing efficient filter maintenance to maximise machine uptime. Changing the filters at the optimum time ensures the dust collector does not draw more kW than required to maintain airflow.
Reverse Pulse Cleaning System
JMS M-Series dust collectors have a plant air connection or an onboard air compressor and receiver tank, which feed the pneumatic system and provide reverse pulse filter cleaning. The pneumatic system’s primary function is to clean out the filters during operation to prevent dust build-up on the filters.
The pressure and frequency of pulse cleaning are adjustable and help reduce the required filter changes.
Patented Drop-Out Box
Our patented drop-out box removes heavy dust particles and shotcrete fibres from the air stream and discharges them through the augers and rotary valves before they hit the filters. This exclusive, patented design extends filter life and allows the units to handle extreme dust loading.
Key Features. Dust Discharge Options.
Hydraulic Reversible Augers Rotary Valves
JMS M-Series dust collectors include hydraulic reversible auger(s) and stainless-steel rotary valve(s) dust discharge system to discharge dust particles to the site floor or 1T bulker bags.
The use of hydraulics to power the auger(s) and rotary valve(s) maximises their efficiency whilst the ability to reverse the auger(s) and force material through the clean out hatches is key to increasing uptime in the event of product build up in the hopper and auger(s). This reduces the maintenance effort and the requirement to have LV and HV electricians servicing a mechanical component.
There are a number of dust discharge configuration options including:
Incline Augers
Front or side incline augers allow dust particles to be discharged to 1T bulker bags.
Wet Discharge Augers
Available on our JMS 40 M-Series, JMS 50 M-Series and JMS 60 M-Series
Dust can be discharged into a slurry auger by the stainless-steel rotary valve and turned into a wet slurry before being discharged to the site floor. This helps to prevent dust reforming.
The slurry auger can be run off plant water. If plant water supply is not attached the machine will discharge material as dust but will not affect operation until the water supply can be restored.
Shotcrete Drop-Out Auger
Available on our JMS 40 M-Series, JMS 50 M-Series and JMS 60 M-Series
An additional shotcrete auger can be added to further protect the filters whilst reducing the likelihood of a blockage in the main discharge augers.
Key Features. Control and Monitoring Options.
PLC (Programmable Logic Computer)
A simple one button start-up / shut-down sequence starts / stops all critical components in a programmed order which increases the efficiency of the unit and provides additional safety for workers. The touch-screen display facilitates ease of operation. On-screen instructions and warnings display error codes which provide a powerful diagnostic tool to support service and maintenance staff. Our proprietary software is designed to enable performance and trend monitoring. This offers extensive possibilities for system optimisation, process analysis and transparency in machine monitoring, along with scheduling preventative maintenance and servicing at optimum times. The dust collectors can be configured to record a full dataset including fan hours, filter life, differential and static pressures, hydraulic pressures, emissions, power usage and more.
CANbus
The CANbus system enhances speed, flexibility, and reliability in communication along with supporting effective troubleshooting and maintenance from off-site. The system retains key alarm logs so that system performance and troubleshooting can be undertaken as required.
Key instruments that use the CANbus system include:
Air Flow Meter
An air flow meter monitors the air flow from the exhaust.
Real Time Emissions Monitoring
Real time particle detectors examine emissions coming out of the clean air exhaust and can be tuned to meet the requirements of any given site. The unit can be programmed to alarm when levels are being approached and exceeded.
Differential and Static Pressure Gauges
The static pressure monitor alerts the operator if it is necessary to turn the system volume up due to a long duct run or if there’s a blockage in the ducting. The differential pressure monitor alerts the operator if filters are blocked or if there are higher than normal dust loads.
Central Automatic Greasing System
Grease banks are fitted as standard to all units.
An automatic greasing system can be fitted as an optional upgrade to ensure all bearings are maintained at correct intervals, extending operational life and reducing the time required at service periods.
Fuel Level Indicator Lights
On diesel units, fuel level indicator lights alert the operator to remaining fuel levels.
Proximity Sensors
On track units, proximity sensors can be added to alert the operator when any object becomes close to the unit when moving.
Safety Features. Protecting the health and safety of workers.
JMS M-Series Dust Collectors offer a number of features that focus on protecting the health and safety of workers by controlling dust and fumes to provide a safe working environment.
Emergency Stops (E-STOPS)
Emergency stop buttons are located on the unit enabling anyone to stop the machine with immediate effect.
Split Starter and Battery Isolators
Split starter and battery isolators allow the use of service lights when the engine is off or being maintained. It also allows access to full machine diagnostics, reducing the risk to service and maintenance staff.
Operation & Maintenance Lights
Operational and maintenance lights have been fitted in key locations on the unit giving operators and maintenance workers clear visibility of components and / or to illuminate working spaces.
Fire Suppression System
To be compliant with country and industry specific regulations, a fire suppression system can be added to units to surround the diesel engine or a chemical suppression system can be added to electric units.
