What is the difference between the -1 and -2 models in the CLH series?

The -1 and -2 designations indicate different configurations, primarily in terms of the number of ML exciters and power. For example, the CLH1848-1 has 1 exciter and 30 kW, while the CLH1848-2 also has 1 exciter but a different weight (9,810 kg vs 5,295 kg). In larger models like the CLH3673, the -1 has 2 exciters and 55 kW, while the -2 has 3 exciters and 90 kW. The -2 models generally offer higher power and weight, which can translate to higher screening force and capacity. When selecting, consider your required throughput and the nature of your feed material.

How do I choose the right CLH model for my application?

Selection depends on several factors: required production capacity (tph), feed size distribution, and available space. Start by determining the required capacity; for example, if you need 800 tph, models like CLH2448-2 (760 tph) or CLH3061-1 (950 tph) could be suitable. Next, consider the maximum feed size; the maximum sieve aperture is 50 mm across all models, so if your feed is larger, you may need a scalping screen ahead. Also, check the width and length to ensure it fits your plant layout. For assistance, Cruston's screening experts can provide configuration and adjustment support.

What maintenance is required for the CLH series?

Regular maintenance includes checking the wear liners and crossbeams for wear, inspecting the ML exciters for proper lubrication and operation, and ensuring all bolts are tightened to the specified torque. The individual crossbeam design allows for quick replacement of worn beams without major disassembly. It is recommended to inspect the screen daily for loose or damaged components and to follow the manufacturer's lubrication schedule for the exciters. Cruston provides a global network for spare parts, wear parts, and maintenance services to support your operation.

Can the CLH series be used for dewatering applications?

Yes, the CLH series is suitable for fine wet screening, washing, and dewatering. The linear motion and high G-force effectively remove moisture from the material bed. For dewatering, it is important to select the correct screen media (such as polyurethane or wedge wire) and to adjust the slope and stroke for optimal water removal. The compact horizontal height is advantageous in dewatering circuits where vertical space is limited. Capacities for dewatering may be lower than dry screening, so consult with Cruston for specific recommendations based on your material characteristics.

How Does the CLH Series Horizontal Vibrating Screen Enhance Your Screening Efficiency?

The Cruston CLH series horizontal vibrating screen is a heavy-duty screening solution designed for high-output applications. Available in 16 models, from the CLH1848-1 with a 1.8×4.8m deck and 30 kW power to the CLH3673-2 with a 3.6×7.3m deck and 90 kW power, this series offers production capacities ranging from 570 tph to 1,150 tph. Each unit features a maximum sieve aperture of 50 mm and is equipped with 1 to 3 ML exciters, depending on the model. The screen's linear motion and compact horizontal height make it ideal for installations with limited vertical space, while its robust construction ensures reliable operation in continuous, demanding environments.

The CLH series excels in mineral processing of metallic and non-metallic ores, including copper, gold, iron ore, silver, lead, nickel, zinc, and molybdenum. It is also widely used in coal preparation plants for fine wet screening, washing, and dewatering. The screen's ability to handle high throughput with precision makes it a critical component in mill discharge circuits, where efficient classification and sizing directly impact downstream recovery rates. By maintaining consistent screening performance, the CLH series reduces recirculating loads and optimizes grinding circuit efficiency.

Compared to other models in the series, the larger CLH3673-2 stands out with its 3.6×7.3m deck, 90 kW drive, and 1,150 tph capacity, making it suitable for the most demanding high-volume operations. The CLH1848-1, with its single exciter and 5,295 kg weight, offers a compact yet powerful option for smaller plants. All models share the same ultra-heavy-duty construction, individual crossbeam design for easy maintenance, and wear protection, ensuring long service life and minimal downtime. Whether you need a single unit for a specific application or a complete screening solution, the CLH series provides the flexibility and reliability required for modern mineral processing.

Core Technical Features and Quantified Advantages

STEP 1

Ultra-Heavy-Duty Construction with Wear Protection

The CLH series is built with an ultra-heavy-duty, robust construction that includes wear protection on critical components. This design ensures a long service life even in abrasive applications such as mill discharge screening and coal preparation. The screen body and crossbeams are fabricated from high-strength steel, and wear liners are strategically placed to protect against impact and abrasion. With weights ranging from 5,295 kg to 19,800 kg, these screens are engineered to withstand continuous operation without compromising structural integrity.

STEP 2

Individual Crossbeam Design for Quick Maintenance

Each crossbeam in the CLH series is individually replaceable, allowing for quick and convenient maintenance without the need to disassemble the entire screen. This design minimizes downtime and reduces maintenance costs. The crossbeams are bolted to the side plates, and their modular nature means that a single damaged beam can be swapped out in hours rather than days. This is particularly beneficial in high-capacity operations where every hour of downtime translates to significant lost production.

STEP 3

Compact Horizontal Height and Linear Motion

The CLH series features a compact horizontal height, making it suitable for installations with limited vertical space. The linear motion produced by the ML exciters ensures reliable and efficient screening, even at ultra-high outputs. The linear stroke is optimized for each model, with the number of exciters varying from 1 to 3 depending on the size. This motion characteristic provides a consistent bed depth and superior stratification, resulting in high screening efficiency and accurate size separation.

STEP 4

High Capacity up to 1,150 tph

With production capacities ranging from 570 tph to 1,150 tph, the CLH series can handle the most demanding throughput requirements. The largest model, CLH3673-2, achieves 1,150 tph with a 3.6×7.3m deck and 90 kW of power. This high capacity is made possible by the efficient linear motion and the large screening area. The screens are ideal for mill discharge and coal preparation, where high tonnages must be processed continuously. The maximum sieve aperture of 50 mm allows for effective coarse and fine screening.
