JMS M-Series Features

Dust Collector Key Components

Mobility. Mobility combined with a compact integrated design – options to suit site access and applications.

Track

Grydale hold international patents for manufacturing the only self-propelled dust collector on the market. Track units offer full mobility with variable speeds between 2-4 k.p.h. to increase the speed and efficiency of operations. 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 activities, reducing the volume of air requiring treatment and improving the efficiency of whole site operations.

Hydraulic Stepping System
The Hydraulic Stepping System powers four legs that lift the units up, while a pair of skates help to move the unit forward /backwards. Movement can be repeated to achieve the desired travel distance.

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.

Castor Wheel Base

Dust collectors mounted on a castor wheel base can be moved easily using one of the two available options:

  • Sliding – the dust collector features compressed rigid castor wheels to allow ease of movement.
  • Lifting – the dust collector also has four designated lifting lugs at each corner of the machine allowing units to be lifted into position.

Castor wheels can be supplied with or without brakes and customised to fit platform rails if required.

Filtration. NATA certified dust collection efficiency of 99.99% at 0.067 micron.

Air Intake

Available in single, dual or multiple forms, the intakes are connected to the dirty air source via ducting. For large dust volumes we recommend single intakes, while multiple intakes can be used to extract dust from multiple sources simultaneously. Flexible couplings allow the dust collector inlet to connect effectively on uneven surfaces.

Filters

High Efficiency Filter Cartridges provide filtration of 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, allowing efficient filter maintenance and maximizing machine uptimes.

Reverse Pulse Cleaning System

All our dust collectors have an on-board air compressor and receiver tank which feed the pneumatic system to 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.

Pressure and frequency of pulse cleaning is adjustable and helps reduce the number of filter changes required. If there is already a compressor on site, this can be utilized.

Drop Out Box

Our patented drop out box takes heavy dust particles and shotcrete fibers out of 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 machine to handle extreme dust loading.

Centrifugal Fan. Optimised air flow, energy efficiency and enhanced durability.

Grydale Dust Collectors feature a Centrifugal Fan that is optimized for the application air flow and pressure requirements. Centrifugal fans offer superior energy efficiency and enhanced durability, allowing them to operate in even the most corrosive environment.

Variable Speed Drive & Velocity Probe

One of the key aspects of Grydale JMS M-Series Dust Collectors is the inclusion of a Variable Speed Drive (VSD) as part of the standard configuration. The VSD is used in conjunction with a high precision Air Velocity Probe to allow power consumption to be regulated to achieve the air volume required. This makes the units power efficient and allows projects to reduce their power consumption by up to 40%.

Fan Silencer

Exhaust air passes through silencers to reduce noise pollution. We can also supply a square to round attachment allowing a vent bag to be attached to the exhaust side if required.

Dust Discharge System. Hydraulic powered reversible augers maximize dust discharge efficiency.

Hydraulic Reversible Augers Rotary Valves

Grydale Dust Collectors feature hydraulic reversible augers and stainless-steel rotary valve discharge system.

The use of hydraulics to power the augers and rotary valves maximizes their efficiency whilst the ability to reverse the augers and force material through clean out hatches is key to increasing up-time in the event of product build up in the auger/hopper. This reduces the maintenance effort and also reduces the requirement to have LV and HV electricians servicing a mechanical component. The augers also have an auto unblock feature.

Dust Discharge Options

Incline augers

Dust Collectors with incline augers allow dust particles to be discharged to 1T bulker bags.

Slurry augers

Available on our JMS 40 M-Series, JMS 50 M-Series and JMS 60 M-Series

Units are fitted with slurry augers to discharge dust from the unit into a slurry auger by the stainless-steel rotary valve and is turned into a wet slurry before being discharged onto the site floor. This helps to prevent it from reforming into dust. The slurry auger can be run off either plant water or the onboard tank 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 box

Available on our JMS 40 M-Series, JMS 50 M-Series and JMS 60 M-Series

The patented drop out box was designed to remove shotcrete and heavier particles from the airstream prior to entering the main filter house chamber and auger system. This design protects the filters whilst reducing the likelihood of a blockage being caused by larger particles or shotcrete fibers.

Control and Monitoring Options. Proprietary software facilitates ease and speed of operation.

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 Models)

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. Maximizing the health and safety of workers.

Key safety features include:

Emergency Stop Lanyard System

Emergency stop buttons are located on the unit. Track and hydraulic stepping systems also feature a safety lanyard system runs around the perimeter of the unit enabling anyone to ‘grab and kill’ 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.
