What is the maximum feed size and separation range of the CLF series?

The CLF series linear vibrating horizontal screening machine accepts a maximum feed particle size of 300mm and separates particles in the range of 1–100mm. This makes it suitable for pre-screening ahead of cone crushers, where feed material can be large and variable. The separation range is achieved by selecting the appropriate screen media aperture and adjusting operating parameters such as stroke angle, rotation speed, and vibration trajectory. For materials with high specific gravity, the linear motion ensures efficient stratification and passage, even when the difference between upper and lower screening limits is small. Always consult the technical manual for specific model capabilities, as larger models may have slightly different feed size limits.

How can I adjust the screening performance of the CLF machine?

The CLF series offers five adjustable parameters to optimize screening performance: tilt angle (by adjusting the spring seat), stroke angle (by moving the vibrator position), stroke, rotation speed (by changing the pulley), and vibration trajectory (from flat ellipse to straight line). These adjustments allow you to fine-tune the machine for different materials and production requirements without replacing major components. For example, increasing the tilt angle can improve throughput for free-flowing materials, while adjusting the stroke angle can reduce blinding in sticky ores. It is recommended to consult the operation manual and perform adjustments incrementally, monitoring screening efficiency and machine load.

What maintenance is required for the CLF series linear vibrating screen?

Routine maintenance includes checking the vibrator bearings for lubrication every 500 hours, inspecting the screen media for wear or damage weekly, and verifying belt tension and pulley alignment monthly. The top-mounted mechanism simplifies these tasks, as the vibrator and motor are easily accessible. For the mining version, inspect the rubber liners at the feed and discharge ends and on the side walls every 1,000 hours, replacing them when wear exceeds 50% of original thickness. Lubricate the bearings with high-temperature lithium grease (NLGI 2) and ensure the screen box is free from material buildup. Following these procedures will maximize service life and minimize unplanned downtime.

How Does the CLF Series Linear Vibrating Screen Improve Ore Crushing Efficiency?

The Cruston CLF series linear vibrating horizontal screening machine is a specialized solution for grading and pre-screening before cone crushers in ore crushing processes. It handles a maximum feed particle size of 300mm and separates particles in the 1–100mm range, making it ideal for high-specific-gravity materials where the difference between upper and lower screening limits is small. Available in single-layer, double-layer, and triple-layer configurations, the CLF series offers screening areas from 3m² (CLF 1030S) up to 21.1m² (CLF 3070D), with installed power ranging from 2 x 5.5kW to 2 x 30kW. The horizontal or low-angle design allows installation in height-restricted sites, while linear or elliptical vibration provides higher screening efficiency than conventional screens. The mechanism is mounted on top of the screen box for easy maintenance, and the robust structure can handle materials with high bulk density.

Typical applications include pre-screening ahead of cone crushers in mining and quarrying operations, where accurate size separation is critical to downstream crushing performance. The CLF series excels when installation space is limited, when the material has a high specific gravity, or when the particle size distribution is narrow. For heavy-duty mining applications, a mining version is available with replaceable wear-resistant rubber liners at the feed and discharge ends and on the side walls, heavy-duty abrasion protection for the screen plate, and thicker rubber liners on the feed box. This extends service life in abrasive environments. The ability to adjust tilt angle, stroke angle, stroke, rotation speed, and vibration trajectory (from flat ellipse to straight line) allows operators to fine-tune performance without replacing major components.

Compared to other models in the CLF series, the CLF 1030S offers a compact footprint with a 1,020mm screen width and 3,000mm length, making it suitable for smaller operations or space-constrained plants. Larger models like the CLF 3070D provide a 21.1m² screening area for high-capacity requirements. The series also offers half-length screen plates as an option, enabling flexible configuration. Whether you need a single-layer unit for simple scalping or a triple-layer machine for precise multi-fraction separation, the CLF series delivers reliable performance with low maintenance. The top-mounted mechanism simplifies servicing, reducing downtime. With a wide range of models and options, the CLF series can be tailored to specific application scenarios, ensuring optimal screening efficiency and throughput.

Core Technical Features and Quantified Advantages

STEP 1

Linear Motion for Higher Screening Efficiency

The CLF series uses linear or elliptical vibration, which increases screening efficiency by up to 30% compared to circular motion screens. This is achieved by directing the vibration force along the screen surface, promoting faster particle stratification and passage. The stroke angle and vibration trajectory can be adjusted from flat ellipse to straight line by moving the vibrator position, allowing optimization for different materials. For high-specific-gravity ores, linear motion reduces blinding and improves throughput, ensuring consistent gradation ahead of cone crushers.

STEP 2

Top-Mounted Mechanism for Easy Maintenance

The vibrator mechanism is installed on top of the screen box, providing unobstructed access for inspection and maintenance. This design eliminates the need to remove the screen deck or crawl under the machine, reducing downtime by up to 40%. Routine tasks such as bearing lubrication and belt tension checks can be performed quickly. The top-mounted configuration also simplifies replacement of the vibrator or motor, as these components are easily reachable with standard tools. This is particularly beneficial in space-constrained installations where side access is limited.

STEP 3

Wear-Resistant Protection for Heavy-Duty Mining

The mining version of the CLF series features replaceable wear-resistant rubber liners at the feed and discharge ends and on the side walls. The screen plate receives heavy-duty abrasion protection, and the feed box is lined with thicker, more wear-resistant rubber. These liners are made from high-grade natural rubber with a tensile strength of at least 18 MPa and abrasion resistance of 120 mm³ (ISO 4649). This extends service life in abrasive applications by up to 50% compared to standard steel liners, reducing maintenance costs and downtime.

STEP 4

Compact Design for Height-Restricted Sites

The horizontal or low-angle design of the CLF series allows installation in height-restricted sites where inclined screens cannot fit. The overall height is minimized, with some models requiring as little as 1.5m of vertical clearance. This makes the CLF ideal for mobile plants, underground mines, or retrofit projects. Despite the compact footprint, the screen box is robust enough to handle materials with bulk density up to 3.2 t/m³. The low-angle design also reduces material free-fall and degradation, improving product quality.
