SSI updates features on Pri-Max primary reducer shredders

SSI Shredding Systems Inc., Wilsonville, Oregon, has updated its Pri-Max primary reducer shredder to include new technologies and features that decrease maintenance costs and improve ease of use. The Pri-Max primary reducer shredder is built to reduce the volume of bulky materials while achieving processing rates of up to 150 tons per hour. According to SSI, the shredder can be incorporated into a system as a primary shredder or used as a stand-alone machine. SSI offers multimaterial reducers that range from 200 horsepower to 600 horsepower.

“SSI continually monitors customer feedback and uses it as the catalyst for product innovation,” says Dave Fleming, director of sales and marketing at SSI. “Pri-Max machines are typically the first step in large processing systems, making them a critical component to customer productivity and success.”

In 2018, SSI began to engineer new technology for maintenance and replacement of wear parts. “Customers wanted longer service intervals and more flexibility in how they could choose to maintain wear parts in their machines,” Fleming says.

SSI reports that its patented “cartridge” table allows the entire wear parts package to be replaced without the need to remove the drive group, bearings or hydraulic connections. Regular hardfacing can be accomplished in the machine or offline as the customer chooses. According to a news release from SSI, this design reduces the time required for service and related downtime.

SSI adds that the heavy-duty, open grate cutting table and strategic cutter placement ensure that abrasives, including aggregate, sand, soils and metal fragments fall directly through the cutting table, reducing wear and operating costs. The extra heavy-duty welded cutting table is available in a variety of configurations to control output size and performance.

Additionally, SSI reports that it has added a new “stackable shaft” design for its Pri-Max machines to allow cutters and spacers to easily slide off the fully welded shafts on the shredders. SSI says these parts can now be replaced while reusing the shafts. This also allows the entire machine to be configurable if material or output needs change. SSI reports that the bidirectional cutters grab, pierce and break materials. They can be hardfaced or tips can be replaced inside the machine or offline as needed.

“These machines have always been popular. We are excited to offer both new and existing customers the ability to have these new features that will reduce the time needed to exchange wear parts, reduce the cost of the parts themselves and simplify the process of working on the machine in general,” Fleming says.
