Filtration Solutions for Cleaner Glass & Ceramic Processing

AST Canada designs innovative dust collection systems, proven in the glass and ceramic processing industries. We design, supply, install and maintain our systems.

Reliable Dust Collection for the Glass & Ceramics Industries

AST Canada supplies reliable dust collection and combustible dust mitigation solutions to fit a variety of glass ceramics processing applications.

With several decades of experience engineering dust collection systems, AST Canada is the name you can trust above all others for solutions to dust, mist & fume collection plus fire & explosion mitigation in industrial settings.

A Variety of Options for the Glass & Ceramics Industries

AST Canada offers innovative dust collection solutions and proven experience in glass and ceramic processing. We design, supply, service and maintain the system we create. We design using rugged, high-performance baghouses collectors, innovative & efficient cartridge collectors or Torit PowerCore® collectors. We offer a wide range of collectors suitable for the glass & ceramics industries.

Special Process and Material Property Considerations

Commercially produced glass can be classified as soda-lime, lead, fused silica, borosilicate, or 96 percent silica with soda- lime glass representing three-quarters of the glass produced. Glass is manufactured from materials that are crushed, weighed, mixed and melted to produce flat glass, container glass, pressed glass and blown glass.

Filter Considerations for Glass Dust

Polyester felt is the typical media choice for baghouse applications on glass production processes at ambient temperatures. Exotic media is often required at elevated temperatures, and selection has to consider the actual chemistry of the process. Protecting bags from direct abrasion is especially important when handling sand or cullet dust streams. Because glass dusts contain high percentages of silica, high levels of filtration efficiency must be a consideration in filter media selection, collector selection, and in collector sizing. Cullet crushing is a challenging dust collection application requiring specific collector design. Intake materials are particularly abrasive, and dust loadings are often very high, so heavy gauge hoppers and airflow management are critical to collector success. Sand, cullet, and limestone bin vents benefit from the advantages offered in both efficiency and size with the CP Series PowerCore collectors. The characteristics of soda ash benefit from the performance of the DLMV in handling potential upset conditions associated with humidity and/or moisture.

Glass Feed Materials
  • Major Ingredients: Sand, Limestone, Soda Ash, and Cullet (broken glass)
  • Minor Ingredients: Salt cake, aluminum oxide, barium oxide and oxides of iron, nickel, manganese and copper added to impart colour to glass.
Glass Dust Characteristics
  • Sand: Course and free flowing
  • Limestone: Usually slightly agglomerative with wide particle size distribution, filters and cleans down easily
  • Soda Ash: Relatively fine with agglomerative characteristics, hygroscopic and should be kept dry
  • Cullet: Large irregular shaped particles, very abrasive

Applications

Crushing

Crushing Application in the glass industry | AST CanadaWhen crushing glass, large irregular-shaped particles are formed, which are very abrasive. Donaldson offers different dust filtration systems equipped where necessary with abrasion resistance inlets suitable for raw material or glass crushing applications.

Furnace

Glass furnace applications are heavy-duty and the materials are typically very abrasive. Donaldson has the expertise and extensive range of dust collectors to provide advanced solutions for this demanding process. The temperature and condensate are other challenges that Donaldson dust collection systems can handle, by tailoring the specification to suit the application to ensure stable, clean and efficient glass production.

Other applications can include intake hoppers and pits, elevators, screw and belt conveyors, holding bins and silos, weigh stations, mixers, feeders, cullet crushers and screens.

Ceramic Floor and Wall Tile

Ceramic Floor and Wall Tile applications include: Conveyors, Elevators, Bins/Silo Vents, Rail/Truck Unloading, Batch Mixing, Spray Glazing, Tunnel Kiln/Furnace, Dry Pressing. Raw materials may include a wide variety of minerals and chemicals. Beyond clay and Cement the list of additional ingredients may include Flint, Feldspar, Alumina, Litharge, Whiting, Magnesite, Talc, Neohheline, Zircon, Borax, Pyrophyllite, Spodumene, Beryl, Lime, Plaster, Cobalt, Boron, Titanium Carbide, Silicone Carbide, Iron Oxide, Barium Titanate, Lead Zirconate, Tin Oxide, Zinc Oxide. These dusts are often abrasive, may be explosive, and are often hydroscopic, and agglomerative. AMR guidance may include cautions regarding the dust characteristics.

Tile manufacturing processes in particular can generate very aggressive applications. Bag life may be limited by higher temperature.
