Fixed Unit Dust Collectors
Grydale are an Australian Original Equipment Manufacturer (OEM) of a range of industrial dust collection equipment.
Our team have over 15 years’ experience designing and manufacturing industrial dust collectors. We focus on adding value through a total service offering, providing ventilation design, manufacture, implementation, ongoing project management and onsite maintenance and technical support.
Our fixed unit dust collectors offer a long term and cost-effective solution to dust and fume control and are designed to maintain compliance with workplace health and safety regulations.
Key Features of Grydale Fixed Unit Dust Collectors
Sizing a Dust Collector.
Custom designed units to meet application and site requirements.
Our fixed unit dust collectors are all designed by our in-house engineering team to meet specific applications and site conditions.
A combination of airflow, air velocity, pressure, resistance and air-to-cloth ratios determines the appropriate size and ducting configuration. Incorrect sizing can result in high emissions, lowered productivity, reduced filter life and a hazardous/unsafe working environment.
Airflow. How much air the system needs to move.
In general terms, the larger the space where extraction is required, or the greater the number of dust collection pick up points, the greater the airflow required.
Variable Speed Drives (VSD) or Variable Frequency Drives (VFD) can be used to adjust the airflow when there are fluctuating site conditions. This can help to reduce power consumption.
Air Velocity. The speed the air needs to move.
For dust to travel suspended in air it must travel at or above the minimum conveying velocity for that product. There are also risks such as explosion, toxicity and abrasion associated with certain dust types to be taken into account.
Low air velocity can cause dust build up within ducting and lead to poor dust capture and fires. This can also create an increased explosion hazard. High air velocity can cause premature wear in the duct work by means of abrasion or can break up delicate conveyed products such as food and pharmaceuticals.
Air-to-Cloth Ratio. Volumetric flow rate of air through a dust collector’s intake divided by the total cloth area (m²) in the filters.
For dust collectors to capture dust from the air-stream, they must have a sufficient number of filters. Maintaining an adequate air to cloth ratio enables the dust collector to operate at peak efficiency. Dust types and the amount of dust per cubic meter are all determining factors.
Pressure and Resistance. >Pressure and resistance across the dust collection system.
The fan used in the dust collector must supply enough suction to overcome duct and fixed pressure losses from the collection point(s), through the dust collector and filters before exhausting clean air out of the system.
Resistance to airflow is created by the filters and ducting along with the dust being transported.
Case Studies
Coastal Powder Coating & Blasting
Sandblasting require a custom dust control solution to handle the large volumes of toxic dust, which, if inhaled, can be hazardous to workers
Bulk Storage Handling
Grydale was commissioned to design, manufacture and install a JMS 48 F-Series dust collection system for each storage shed to manage dust created through loading and unloading the zinc and copper product.
Crushing Plant Dust Extraction System
Situated in Australia's remote, Gulf of Carpentaria, the McArthur River Mine (MRM) is a world-class zinc and lead mine and crushing plant.
Zinc Bulk Storage Shed, Bing Bong, NT
At Glencore’s loading facility at Bing Bong, Zinc is stored in a bulk storage shed which needs to be fully contained to protect against spillage and ensure environmental security and prevent loss of valuable product.
Bing Bong Bulk Storage Shed
Our client has two 8000m2 sheds that store zinc and copper concentrate before being distributed to customers across the globe. Zinc and Copper dust needed to be fully contained within each shed to protect against spillage, avoid cross contamination and ensure environmental security. Grydale were commissioned to design, manufacture and install a JMS 48 F-Series Dust Collection System for each storage shed (zinc and copper) to manage dust created through loading and unloading product.
