What is the maximum processing capacity of the CCVB Series, and how does it vary across models?

The CCVB Series offers processing capacities ranging from 400 tph for compact models like the CCVB1540-1P up to 1200 tph for larger models such as the CCVB2661-1P. Capacity depends on screen area, number of decks, and material characteristics. For example, the CCVB2661-1P with a 2.6 m × 6.1 m screen and single deck handles 1200 tph, while the CCVB1540-1P with 1.5 m × 4.0 m screen handles 400 tph. When selecting a model, consider the required cut size, bulk density, and moisture content to ensure optimal performance.

How do I determine the correct installation angle for my application?

The installation angle can be set between 12° and 22° based on material characteristics and screening objectives. For dry, free-flowing materials, a lower angle (12-15°) increases retention time and improves screening efficiency. For sticky, moist, or high-clay materials, a steeper angle (18-22°) accelerates material flow and reduces blinding. Start with a mid-range angle (15-18°) and adjust based on observed performance. The screen frame is designed for easy angle adjustment using shims or hydraulic systems, depending on the model.

What maintenance is required for the MV exciters, and what is their expected service life?

MV exciters require periodic greasing (typically every 500-1000 hours, depending on operating conditions) and inspection of bearings and seals. The exciters are designed for a service life of 20,000 to 30,000 hours under normal operating conditions. However, factors such as load, speed, and environmental conditions can affect lifespan. Regular vibration analysis and temperature monitoring can help detect early signs of wear. Replacing bearings and seals at recommended intervals ensures reliable performance and prevents unexpected downtime.

Can the CCVB Series be used for both dry and wet screening applications?

Yes, the CCVB Series is suitable for both dry and wet screening. For wet applications, additional features such as water spray bars and corrosion-resistant screen media may be required. The weld-free frame and Hooke bolt connections are designed to withstand moisture and slurry exposure, but regular inspection of bolts and seals is recommended. The adjustable angle also helps in wet screening by allowing optimal drainage and material flow. Consult Cruston for specific modifications for wet applications.

How Does the CCVB Series Circular Vibrating Screen Achieve Optimal Screening Efficiency?

The Cruston CCVB series circular vibrating screen is a heavy-duty solution designed for continuous operation in the most challenging environments. At its core, the screen features a central axis positioned at the center of gravity, which generates a uniform omnidirectional circular motion. This motion, combined with an adjustable installation angle ranging from 12° to 22°, allows for precise control over material travel speed and bed depth. The series encompasses 37 standard models, from the compact CCVB101 with a 5.7 m² screen area to the large CCVB603 with 22.5 m², accommodating 1 to 4 decks and processing capacities up to 1200 tph. The weld-free frame design eliminates fatigue stress points, significantly extending equipment lifespan even under high-tonnage loads.

Typical applications for the CCVB Series include pre-screening, inspection screening, and final screening in industries such as mining, quarrying, and construction aggregates. The adjustable angle is particularly beneficial when dealing with sticky or moist materials, as a steeper angle (up to 22°) increases material velocity and reduces blinding. The robust frame and Hooke bolt connections ensure consistent assembly conditions, eliminating loose connections that can cause downtime. With MV exciters providing up to 4G force, the screen efficiently separates materials even at high throughputs, making it an ideal choice for operations requiring high capacity and reliability.

Compared to other vibrating screen types, the CCVB Series stands out for its economic advantages. The inclined screen design requires lower investment cost and energy consumption than horizontal screens of similar capacity. The use of standardized MV exciters and wear parts reduces inventory costs and simplifies maintenance. Additionally, the weld-free side plates and frame minimize the risk of structural failure, reducing unplanned downtime. For operations seeking a balance between performance and total cost of ownership, the CCVB Series delivers unmatched value.

Weld-free frame and side plates reduce fatigue stress and extend equipment lifespan by up to 30% compared to welded designs.
Adjustable installation angle of 12-22° allows optimization for various material characteristics and screening objectives.
MV exciters provide up to 4G force, ensuring efficient screening even at capacities up to 1200 tph.

Core Technical Features and Quantified Advantages

STEP 1

High Excitation Force up to 4G

The MV exciters generate up to 4G of excitation force, ensuring efficient material stratification and separation even for high-density ores and large particle sizes. This high force is achieved through a robust design with dual MV exciters (e.g., 2xMV2, 2xMV3, 2xMV4) that are precisely timed to produce a circular motion. The result is consistent screening performance with minimal blinding, reducing downtime and increasing throughput.

STEP 2

Adjustable Tilt Angle 12-22°

The installation angle can be adjusted from 12° to 22°, allowing operators to fine-tune the screen for specific material properties. A lower angle (12°) is ideal for fine screening where retention time is critical, while a steeper angle (22°) enhances material flow for sticky or moist feeds. This flexibility ensures optimal efficiency across diverse applications without compromising capacity.

STEP 3

Weld-Free Frame Construction

The frame and side plates are assembled without welding, using high-strength bolts and Hooke bolt connections. This design eliminates heat-affected zones and residual stresses that can lead to fatigue cracks. As a result, the screen withstands continuous high-load operation, with a structural lifespan extended by up to 30% compared to conventional welded frames, reducing maintenance costs and downtime.

STEP 4

MV Exciter Technology

The MV exciters are modular, self-contained units that provide reliable, long-lasting performance. Each exciter is designed for easy maintenance, with grease-lubricated bearings and a robust housing. The use of multiple exciters (e.g., 2xMV2, 4xMV3) allows for scalable force output, matching the screen size and application requirements. This modularity simplifies spare parts inventory and reduces replacement costs.
