The CVS-1240 stands out as one of CONSTMACH's most versatile screening solutions, engineered specifically for operations requiring reliable material separation at medium capacity ranges. This model delivers consistent performance across a wide spectrum of applications, from aggregate processing to mineral classification, making it an essential component in modern crushing and screening plants.
What makes the CVS-1240 particularly noteworthy is its adaptability to different operational requirements. The screen is available in multiple deck configurations—ranging from double to quadruple deck setups—allowing operators to achieve precise material gradation in a single pass. Each deck spans 4.8 square meters with dimensions of 1,200 mm by 4,000 mm, providing ample screening area for efficient material processing. This generous screening surface enables the unit to handle between 70 and 95 tons per hour, depending on material characteristics and deck configuration selected.
The machine's mechanical design reflects years of refinement in vibrating screen technology. CONSTMACH offers two distinct drive configurations for this model: top-driven and center-driven systems. This flexibility lets operators choose the setup that best matches their plant layout and maintenance preferences. The heart of the system consists of precision-machined and ground forged steel eccentric shafts that generate the necessary vibration patterns for effective screening. These shafts undergo rigorous quality control to ensure perfect balance and longevity under continuous operation.
Bearing performance is critical in vibrating equipment, and the CVS-1240 addresses this through carefully engineered bearing housings that maximize shaft strength and bearing fit. The unit employs premium bearings from industry leaders including SKF, FAG, Timken, and NSK, with options for either grease or oil lubrication systems based on operational demands. This attention to bearing selection and lubrication significantly extends service intervals and reduces unplanned downtime.
The screen mesh selection offers another layer of customization. Operators can specify either steel wire mesh for conventional applications or polyurethane panels when dealing with particularly abrasive materials or when noise reduction becomes a priority. Polyurethane panels also tend to blind less frequently with sticky materials, maintaining screening efficiency throughout the shift.
Structural integrity receives equal attention in the CVS-1240's design. Deck support frames are available in both crowned and flat configurations, with all frames stress-relieved to prevent premature failure from vibration-induced fatigue. The construction employs Huck bolt fasteners throughout, creating joints that resist loosening even under severe vibration conditions. This fastening method has proven exceptionally reliable in field applications where traditional bolted connections often require frequent retightening.
Material handling components incorporate wear-resistant features that extend operational life. The feedbox and discharge areas utilize bolted and welded steel liners that can be replaced as they wear, protecting the main structure from abrasion damage. This modular approach to wear components means operators can perform targeted maintenance without extensive disassembly or welding repairs.
Power requirements for the CVS-1240 vary with deck configuration. Double deck units operate with a 7.5 kW motor, while triple and quad deck versions require 11 kW motors to maintain proper vibration amplitude across the additional screening surfaces. These power specifications represent efficient operation without oversizing drive components. Operating weight ranges from 7,400 kg for the two-deck model up to 8,000 kg for the four-deck configuration, figures that facilitate transportation and installation planning.
The modular construction philosophy extends beyond wear components to include all major assemblies. This design approach simplifies both routine maintenance and parts replacement, reducing the technical expertise required for field service. Operators appreciate this accessibility when performing inspections or changing screen media between production runs handling different material specifications.
CONSTMACH's vibrating screens have earned their reputation in demanding applications worldwide. The CVS-1240 continues this tradition by combining proven mechanical principles with practical engineering solutions that address real-world operating challenges in aggregate production and material processing operations.
