CVS-1650 | Vibrating Screen

CVS-1650 is a mid-to-large model in the CONSTMACH inclined vibrating screen series, designed to classify crushed material into accurate size fractions in medium-to-large crushing and screening plants. Its screen box measures 1.600 x 5.000 mm, providing 8 m² of deck area and a rated capacity of 130-160 tons per hour. Compared with the CVS-1640, the CVS-1650 keeps the same 1.600 mm width but extends the deck length to 5.000 mm, which lengthens the material's residence time on the mesh and improves separation efficiency, particularly on near-size particles.

A vibrating screen carries out multi-deck size separation: feed enters the top deck, and as the box vibrates, undersize passes through each mesh while oversize travels to discharge. The CVS-1650 is offered in two, three and four deck configurations, splitting feed into three, four or five graded products in a single pass. The two-deck base version is driven by an 11 kW motor and weighs 14.000 kg; the three-deck version uses 15 kW at 14.750 kg, and the four-deck version uses 18.5 kW at 15.500 kg.

Installed after a crusher and fed by a belt conveyor, the CVS-1650 produces the saleable aggregate fractions, for example 0-5, 5-12, 12-22 and 22+ mm, according to the installed mesh. Oversize from the bottom deck is generally returned to a crusher in closed circuit, while the through-products report to stockpile conveyors. As gradation accuracy directly determines product value and specification compliance, the screen is one of the most quality-critical machines in the line, and the longer deck of this model supports tighter cuts at higher tonnage.

The CVS-1650 can be produced in driven-from-top or driven-from-center versions. Its eccentric shaft is precision machined and ground from forged steel for balanced excitation, and bearings are sourced from SKF, FAG, Timken or NSK. The deck support frames are stress-relieved and supplied crowned or flat, with Huck bolt fastener construction maintaining joint integrity under continuous vibration.

Screen media can be steel woven mesh or polyurethane panels, selected according to material hardness, abrasiveness and required aperture. The 5.000 mm deck length gives the bed more time to stratify, so fine material reaches the mesh more reliably. The bolted and welded, abrasion-resistant steel-lined feedbox and discharge lips protect the high-wear zones and are replaceable.

The modular structure keeps the unit within standard transport dimensions and simplifies spare-part changes and routine maintenance, supporting high availability in medium-to-large lines.

The CVS-1650 is best understood as the long-deck partner to the CVS-1640: both share the 1.600 mm width, but the 1650 extends the deck from 4.000 mm to 5.000 mm. That extra metre of length increases the deck area to 8 m² and, more importantly, lengthens the time each particle spends travelling over the mesh. Longer residence time is what improves the separation of near-size particles, the material whose dimension is close to the aperture and which is hardest to classify. The two-deck version runs on 11 kW, the three-deck on 15 kW and the four-deck on 18.5 kW, with the higher power matched to the greater deck area and the 130-160 t/h capacity.

For aggregate producers and quarries running medium-to-large plants, the CVS-1650 delivers accurate, repeatable size separation at 130-160 t/h, converting crusher output into clean, specification-graded products with minimal cross-contamination between fractions.
