What is the maximum screening area available in the CES Series?

The maximum screening area in the CES Series is 17.8 m², available in models CES 502 and CES 503. These models feature sieve plate dimensions of 2,480 x 7,300 mm. The CES 502 has two sieve layers, while the CES 503 has three. The large screening area allows for high capacity processing, making these models suitable for large-scale mining and aggregate operations. When selecting a model, consider the required throughput, available space, and the number of size fractions needed. The 17.8 m² area provides ample capacity for high-tonnage applications while maintaining efficient screening performance.

How does the CES Series handle high moisture content and sticky materials?

The CES Series is specifically designed to handle high moisture content and sticky materials through its unique elliptical motion generated by counter-rotating, unbalanced dual shafts. This motion creates a combination of circular and linear movements that help to break up agglomerates and prevent blinding. The high excitation force of up to 6G further aids in dislodging sticky particles. Additionally, the adjustable tilt angle (0-5°) allows operators to optimize the material flow for specific conditions. The 50% larger interlayer spacing reduces the chance of material buildup between layers. These features ensure continuous and accurate sorting even with viscous feed, making the CES Series ideal for wet screening applications.

What maintenance is required for the CES Series vibrating screen?

The CES Series requires minimal maintenance due to its simple structure and the absence of mechanical timing devices, gear mechanisms, and lubricating oil leaks. The MV™ vibrator is designed for long service life and easy maintenance. Regular checks should include inspection of the sieve plates for wear or damage, verification of the vibrator oil levels (if applicable), and tightening of fasteners. The 50% larger interlayer spacing facilitates easier access to the sieve layers for inspection and replacement. It is recommended to follow the manufacturer's maintenance schedule, which typically includes periodic lubrication and replacement of worn components. The low failure rate of the CES Series ensures high uptime and reduced maintenance costs.

Can the CES Series be used for wet screening applications?

Yes, the CES Series is highly suitable for wet screening applications. Its elliptical motion and high excitation force effectively handle wet and sticky materials that would blind conventional screens. The adjustable tilt angle allows for optimization of water drainage and material flow. The screen's construction materials and coatings can be selected to resist corrosion in wet environments. The 50% larger interlayer spacing helps prevent water and fines from accumulating between layers. Many CES Series screens are successfully operating in wet screening circuits in mining and aggregate plants, demonstrating their reliability and efficiency in such conditions.

How Does the CES Series Horizontal Vibrating Screen Handle Wet and Sticky Materials?

The Cruston CES series horizontal vibrating screen is a high-performance screening solution that employs a pair of counter-rotating, unbalanced dual shafts to produce a highly efficient elliptical motion. This motion is more effective than the linear motion of conventional horizontal screens and more reliable than other elliptical vibrating screens. The CES Series is available in eight models, with screening areas from 9.1 m² to 17.8 m² and sieve plate dimensions ranging from 1,870 x 4,880 mm to 2,480 x 7,300 mm. The number of sieve layers can be 2 or 3, and the MV exciter configurations vary from 2×MV2/2×MV3 to 2xMV3/4xMV3. Weights range from 9,500 kg to 22,500 kg. This series is designed to provide continuous and accurate sorting even under conditions of high moisture content and viscous feed, making it suitable for challenging applications such as wet screening or screening of sticky and impurity materials.

The CES Series excels in industries where material stickiness and moisture content often cause blinding and reduced efficiency. From ore to gravel, the screen handles all types of materials with reliable performance and precise screening. The elliptical motion generated by the dual shafts creates a vigorous action that helps to dislodge near-size particles and prevents clogging, ensuring uninterrupted operation. This is particularly beneficial in mining, quarrying, and aggregate processing, where wet or sticky feed can quickly render traditional screens ineffective. The CES Series offers a 25% higher output compared to conventional screens of the same specifications, directly translating to increased productivity and lower cost per ton. Additionally, the absence of mechanical timing devices, gear mechanisms, and lubricating oil leaks minimizes downtime and simplifies maintenance, further enhancing operational efficiency.

Within the CES Series, each model is optimized for different capacity and space requirements. For instance, the CES 202 and CES 203 share the same 1,870 x 4,880 mm sieve plate and 9.1 m² screening area, but the CES 203 has three sieve layers instead of two, allowing for more precise size separation. The CES 302 and CES 303 offer a larger 11.4 m² area with 1,870 x 6,100 mm plates, while the CES 402 and CES 403 step up to 2,480 x 6,100 mm and 15.1 m². The largest models, CES 502 and CES 503, feature 2,480 x 7,300 mm plates and a 17.8 m² screening area, with the CES 503 available with either 2xMV3 or 4xMV3 exciters. Compared to other elliptical vibrating screens, the CES Series has a 50% larger interlayer spacing, which facilitates easier maintenance and reduces the risk of material buildup between layers. This design consideration, combined with the simple structure and low failure rate, makes the CES Series a reliable and cost-effective choice for demanding screening applications.

Excitation force up to 6G ensures aggressive screening action and high efficiency.
Adjustable tilt angle from 0 to 5 degrees allows fine-tuning for optimal material flow and screening performance.
MV™ vibrator technology provides reliable, long-lasting operation with minimal maintenance.

Core Technical Features and Quantified Advantages

STEP 1

High Excitation Force up to 6G

The CES Series generates an excitation force of up to 6G, which is significantly higher than many conventional screens. This high force is achieved through the counter-rotating, unbalanced dual shafts that produce an elliptical motion. The 6G force ensures that even the most difficult materials, such as wet and sticky ores, are effectively separated. This results in higher screening efficiency and reduced blinding, allowing for continuous operation without frequent stoppages for cleaning. The robust design of the MV exciter supports this high force while maintaining reliability and low maintenance requirements.

STEP 2

25% Higher Output than Conventional Screens

Compared to conventional screens of the same specifications, the CES Series delivers 25% higher output. This is primarily due to the efficient elliptical motion that promotes faster material stratification and passage of undersize particles. The increased output means that for the same footprint, a CES screen can process more material per hour, reducing the number of units required and lowering capital expenditure. This advantage is particularly valuable in high-throughput operations where maximizing productivity is critical. The 25% figure is based on comparative tests under typical operating conditions.

STEP 3

Adjustable Tilt Angle 0-5°

The CES Series features an adjustable tilt angle ranging from 0 to 5 degrees. This allows operators to fine-tune the screen's inclination to match specific material characteristics and desired separation efficiency. A steeper angle increases material travel speed, which can be beneficial for highly viscous materials, while a shallower angle increases retention time for better screening of fine particles. This adjustability ensures optimal performance across a wide range of applications and feed conditions, enhancing the versatility of the screen.

STEP 4

50% Larger Interlayer Spacing

Compared to other elliptical vibrating screens, the CES Series has a 50% larger interlayer spacing. This design feature provides more room between sieve layers, which facilitates easier inspection and maintenance. It also reduces the risk of material accumulation and bridging between layers, a common issue in multi-layer screens handling sticky materials. The larger spacing contributes to the screen's ability to handle high moisture content and viscous feed without clogging, ensuring consistent performance and extended service intervals.
