The CONSTMACH CVS-2050 is an inclined vibrating screen with a deck size of approximately 2,000 x 5,000 mm and a rated capacity of 170-220 t/h. The sections below outline what it produces, its main specifications, applications, deck configuration options, and the maintenance considerations associated with the screen media and vibrating mechanism.
What does the CVS-2050 do?
The CVS-2050 separates a feed of mixed-size granular material into several size fractions. Eccentric-shaft vibration causes material to stratify and travel along inclined screen decks, with undersize particles passing through the mesh apertures and oversize particles carried over the end of each deck. The number of products obtained corresponds to the number of decks plus the final oversize stream.
What are the main specifications?
- Deck dimensions: 2,000 x 5,000 mm
- Layer area: 10 m2 per deck
- Deck configurations: 2, 3 or 4 decks
- Capacity: 170-220 t/h
- Motor power: 15 kW (2-deck), 18.5 kW (3-deck), 22 kW (4-deck)
- Operating weight: 16,500 kg (2-deck), 17,400 kg (3-deck), 18,200 kg (4-deck)
What are the typical applications?
The CVS-2050 is used in aggregate production and crushing-screening plants to classify crushed stone, gravel and sand into commercial size fractions. It is positioned downstream of primary, secondary or tertiary crushers to produce graded products and to return oversize material for further crushing.
How is the deck configuration selected?
The CVS-2050 can be supplied as a 2, 3 or 4 deck unit. A 2-deck screen yields up to three products, a 3-deck screen up to four, and a 4-deck screen up to five, including the final oversize. Increasing the number of decks increases the number of fractions produced and the installed motor power, from 15 kW for the 2-deck version to 22 kW for the 4-deck version.
What maintenance and wear factors apply?
Screen media is the principal wear item and can be specified as steel mesh or polyurethane according to the hardness of the material being screened. Other maintenance points include the eccentric shaft and its bearings, the support springs, the abrasion-resistant feedbox and discharge lips, and the deck tensioning. The modular construction allows spare parts to be changed and maintenance carried out without dismantling the complete machine.
How do the CVS models compare?
The CVS series shares a common inclined, eccentric-shaft design and differs mainly in deck size and capacity. The CVS-1640 (1,600 x 4,000 mm) is rated at 100-130 t/h, the CVS-1850 (1,800 x 5,000 mm) at 140-180 t/h, the CVS-2050 (2,000 x 5,000 mm) at 170-220 t/h, and the larger CVS-2470 (2,400 x 7,000 mm) at 268.8-336 t/h. Model selection is based on the required throughput and the deck area needed for the target fractions.
