At Micronics, we are often heard saying that filter cloth is the key ingredient to an efficient, effective filter press operation. Think of it as the foundation for your dewatering process. Yet, no matter the superiority of the filter cloth – and ours is pretty darn terrific – ensuring an excellent filter cloth/filter plate fit is absolutely critical for top press performance. Different cloth attachment methods are used for different situations.
What Are My Options for Filter Cloth Attachment?
Home > What Are My Options for Filter Cloth Attachment?
Cloth Attachment for Non-Gasketed Plates
Non-gasketed filter cloth and plates typically use zip ties in conjunction with rubber cloth “dog washers.” For the tops of the plates, the grommets on the filter cloth are aligned with the cloth dogs with every grommet positioned over a cloth dog. The cloth dogs are then typically secured with rubber washers. For the sides of the plates, the grommets are secured with zip ties and any excess in zip tie length can simply be clipped.
Use of Velcro® Brand Fasteners
Use of VELCRO® brand fasteners is another method for attaching filter cloth to filter plates. Use of VELCRO® brand fasteners provide a lapping joint, which has superior strength and keeps the filter cloth correctly aligned throughout the many months of the cloth’s operational life and gives “a perfect fit.” As an attachment method, use of VELCRO® brand fasteners makes for easy cloth repositioning or releasing for plate inspection or adjustment. We have found that some customers prefer the ease of installation using Velcro® brand fasteners over the use of zip ties. Additionally, it has been our experience that chemical manufacturing companies often prefer the use of Velcro vs. zip ties and dog washers to avoid even the remote possibility of plastic parts falling into the product.
Cloth Attachment for CGR Plates
For caulked and gasketed recessed filter plates –CGR filter plates – the filter cloth is actually installed in grooves within the plates using a special lightweight manual air hammer, available from Micronics. You can learn more about the use of CGR vs Non-CGR Plates and Cloth in this recent Micronics blog post.
Use of Rod Suspension for Cloth Attachment
Rod suspension is another cloth attachment method, commonly used in large mining and mineral processing operations. In addition, it is not uncommon for Micronics to supply filter cloths designed for rod suspension on some overhead filter presses as well as for customers who may be using older filter presses by Edwards and Jones (E&J).
