H-Class models V-50 and older can be updated to the current V-85 H-Class model to reduce operating noise to levels below 100 dBA, gain better control over the running frequency and decrease maintenance costs by as much as 50%.
The H-Class' modular design uses pre-engineered components, which allows the machine to be easily configured based on an operation's requirements. The machine is effective for screening hot materials, such as phosphate and potash. The V-85 conversion kit can be installed in one day. The package includes the heavy-duty welded bridge, A/C drives, controls and optional rubber dust covers for hot or cold applications.
Karen Thompson, president of Haver & Boecker Canada, said: "As an industry leader, we offer our customers an array of services and upgrades to improve their equipment and add value to their processes, which is why we offer conversion kits. A conversion helps reduce maintenance for our customers and improve their ROI."
Prior to beginning the conversion process, the machine will be evaluated by a Haver service technician to determine if it is eligible for an upgrade. The conversion process begins by removing the entire interior portion of the machine, including the screen media, brackets, post and centre strips. Once removed, the interior is cleaned and prepared for the new deck. New deck brackets are installed and adjusted to the correct level. The vibrating centre strips can be upgraded using silicone liners to handle higher temperatures. Tensioning hardware is also updated, as well as the variable frequency speed unit (VFD), to provide optimum screening efficiency.
H-Class V-85 machines are safe for use in unreinforced structures since movement is confined to the media, which moves with a fast, small stroke to screen materials through openings ranging from 3/16in (4.76mm) to 80 mesh (0.177mm). The upgraded machine offers two variable speeds: The Running cycle operates at 42-48Hz to screen particles and can be modified to an operation's specific needs, while the short Burst cycle increases the vibratory motion to 60Hz to clean the screen, preventing blinding and increasing productivity.
