Linear vibrating screen-Henan Keming Machinery Equipment Co., Ltd.

Working principle

The linear vibrating screen is a high-efficiency industrial screening machine driven by dual vibration motors. By generating synchronous reverse excitation force, it produces stable horizontal linear vibration, pushing materials forward evenly on the screen surface to achieve continuous grading, dewatering, dedusting and impurity removal.

The linear vibrating screen is driven by two vibrating motors. The two motors rotate synchronously and reversely at the same speed. The eccentric blocks generate excitation forces. The forces parallel to the motor axis cancel each other out, while the forces perpendicular to the motor axis are superimposed, forming a single linear exciting force. This drives the screen box to vibrate linearly. Material is fed onto the screen surface, thrown up and moved forward in a straight line, and is graded through one or more screen decks. Different particle sizes are discharged from their respective outlets.

Advantages

Stable Vibration & High Screening Efficiency

Dual-motor synchronous drive delivers consistent linear vibration, enabling uniform material dispersion and forward movement. It effectively prevents material accumulation and screen clogging, achieving a screening efficiency of over 95%.

Large Throughput & Continuous Operation

The extended flat screen surface maximizes screening area and material retention time, supporting high-volume continuous production. It perfectly matches large-scale industrial production line requirements.

Rugged Structure & Low Failure Rate

Integrally welded screen box and thickened steel frame provide excellent load-bearing and impact resistance. Premium wear-resistant core components ensure stable long-term operation and extended service life.

Flexible Adjustable Parameters

TVibration amplitude, frequency and screen inclination angle are all adjustable. The machine can be flexibly optimized to adapt to materials of different particle sizes and humidity, fitting diverse working conditions.

Frequently Asked Questions

Q1:What is the difference between linear and rotary vibrating screens?

Linear vibrating screens adopt straight-line vibration, ideal for large-output grading and dewatering of medium and coarse materials for mass production. Rotary vibrating screens apply 3D circular vibration, mainly for high-precision fine powder screening with smaller capacity.

Q2: How to avoid screen mesh blocking?

The machine can be equipped with anti-clogging bouncing balls. Reasonably adjusting feeding speed and vibration amplitude also effectively prevents material accumulation and mesh blocking for stable continuous operation.

Q3: Can it process wet materials?

Yes. It has excellent adaptability to both dry and wet materials. It is widely used for dewatering and desliming of ore pulp, coal slime and other wet materials.

Q4: Is the screen mesh replaceable?

Yes. The screen mesh is a wearable part with simple and fast disassembly. We provide stainless steel and manganese steel meshes for selection.

Q5: Do you support customized machines?

Customization is available. We can adjust screen size, layer quantity, voltage, dust-proof structure and mobile base according to customer site conditions and output demands.
