Types of filter presses There are two main types of filter presses: overhead beam and side beam. Each type has its own advantages and disadvantages depending on the user's needs. Overhead Beam (OH): Filter plates hang from overhead beams. - Filter cloth change is easier because the overhead beam doesn't obstruct access to plates while they are in place on the press. - Operator has easier access for cloth washing and inspection, due to wider plate openings. - Dynamic loads are typically iso- lated from the beams of the press using tension shafts in various configurations. Side Beam (SB): Filter plates hang from side beams. - High speed cake discharge systems are available. - Plate shaking systems aid in cake release. - They are suitable for portable applications. - Automated rain style or one-by-one high pressure cloth washing systems are available. Properly size your filter press Poor planning in sizing and design can cause unwanted wear problems. If under sizing occurs, it can result in high inlet velocities that cause excessive wear on the feed pumps, feed piping, filter cloths and, eventually, filter plates. Sites should select filter cloth styles and material based on inlet velocity to ensure they have selected the best material that will last the longest. Also, take into consider- ation costs to replace worn or torn filter cloths. Another problem undersized filter presses face is excessive opening and closing speed resulting in high wear and tear on mechanical components. Along with sizing, testing your slurry is imperative to select the filter press best for optimal performance and low maintenance cost. Placing a filter press Where is the filter press going to be placed? Like proper sizing, the location of the filter press is also an important factor. When deciding on the site location of a filter press, several factors should be taken into consideration, including the following: - Thickener/clarifier location, - Slurry feed storage tank location, - Storage space below the press for dewatered cake material or for a info@unifiedscreening.com www.unifiedscreening.com 866.968.3697 Quality control sets Unified apart.
