What's the biggest fear when choosing equipment? It's buying cheap equipment only to find it expensive to use – frequent screen replacements, monthly bearing replacements, burnt-out motors, cracked screen frames… the total repair costs can exceed the initial purchase price of a good machine. Composite screens are used as "long-term equipment" by many companies requiring screening because their structural design incorporates genes for longevity.

Secret 1: Low Vibration Design, Protecting its Structure

Traditional vibrating screens rely on strong vibration for screening. Motor vibration is directly transmitted to the screen frame and machine frame. Over time, weld cracking and bolt loosening are common occurrences. The vibration source of a composite screen comes from the balanced drive of a counterweight. The overall amplitude is small, and start-up and stopping are smooth. The screen frame is almost unaffected by impact forces, and even after three to five years, the structure remains as sturdy as ever.

Secret 2: Self-Cleaning Screen Design, No Clogs Worries

Screen clogging is the "number one killer" of screening equipment. Our composite screen features a dual cleaning system at the bottom of the screen frame, consisting of elastic balls and a scraper. The elastic balls continuously bounce and impact the screen, while the scraper periodically sweeps across the screen surface, making screen clogging a rare occurrence. This extends the screen's lifespan from 1-2 months to 6-8 months, and for some free-flowing materials, it can even last a year without screen replacement.

Secret 3: Optimized Bearing and Lubrication System

The drive bearings utilize heavy-duty imported bearings, coupled with an automatic lubrication system that automatically lubricates every 200 hours, preventing burnout due to human error. The bearings are designed for a lifespan exceeding 50,000 hours—meaning they can last 8-10 years even with continuous 16-hour operation per day.

Materials are also top-notch: the screen frame is made of thickened carbon steel or stainless steel with multi-layer anti-rust coating; parts in contact with materials can be made of 304/316L stainless steel; and the dust cover is removable for easy cleaning and maintenance.

Equipment is an investment, not a consumable. A good composite screen is profitable after ten years, breaks even after five years, and loses money if it breaks down after one year. Every piece of our equipment is designed and manufactured with a ten-year lifespan as the standard. Choosing us means choosing more than just a machine; it's choosing peace of mind—allowing you to focus your energy on production, not in the maintenance room.
