en.Wedoany.com Reported - Wittmann Group has recently expanded its S-Max pelletizer series with the addition of the screenless S-Max Primus pelletizer. This product series utilizes soundproofing materials to reduce operating noise. Its compact footprint allows it to be placed close to injection molding machines, and the design emphasizes low-maintenance operation and long service life.
The S-Max Primus pelletizer is available in two sizes. The smaller model is suitable for injection molding machines with a clamping force of up to 150 tons. It features a cutting chamber measuring 9.4 inches by 9.8 inches, is equipped with two cutting blades, has a motor output power of 0.75 kW, and offers a throughput of approximately 17.6 pounds per hour. The larger model is suitable for injection molding machines with a clamping force of up to 400 tons. Its cutting chamber measures 9.4 inches by 15.7 inches, it is equipped with three cutting blades, has a motor output power of 1.5 kW, and provides a throughput of 44 pounds per hour.
This series of pelletizers operates at a low speed of up to 27 revolutions per minute, enabling it to process various engineering plastics, including styrene, acrylate plastics, and glass fiber-reinforced materials. The low-speed operation helps maintain uniform granulate particle size, reduces dust and noise, minimizes tool wear, and lowers energy consumption. Due to its screenless design, the cutting chamber is easy to clean, which contributes to faster material changeover efficiency.
The granulate collection bin is made of stainless steel, and an observation window provides visibility into the cutting chamber. The feed hopper incorporates soundproofing material between two stainless steel plates to reduce noise when material impacts the inner walls. To prevent material clogging, the downstream flexible hose used for discharging granulate features a beveled cut at the front end, and the airflow in the outlet pipe is adjustable. Both pelletizer models have a width of 27.1 inches. The S-Max 2 Primus measures 27.4 inches in length and 52.6 inches in height, while the S-Max 3 Primus measures 33.5 inches in length and 55.1 inches in height.
Wittmann Group states that the S-Max Primus pelletizer series is designed to meet the demands of machine-side recycling applications, balancing operational efficiency with user convenience.
