Labyrinth Screen Vibration Machine 180t/H - 240t/H Vibrating Sieve

The XY Vibrating Screen is a mature solution developed to overcome the low efficiency, short service life, and high pollution of traditional vibrating screens. Through finite element dynamic analysis of the frame structure, combined with years of field experience in mining crushing and screening, this equipment delivers exceptional fatigue resistance and reliability. Its dual excitation force—generated by shaft eccentricity and eccentric blocks—produces strong vibration, ensuring high throughput, high efficiency, and low operating costs.

• Accurate Screening – Precise classification across multiple deck layers.
• Double Exciting Force – Powerful vibration for demanding applications.
• Sturdy & Durable – Built for continuous heavy-duty operation.
• Strong Vibration – Optimized amplitude and frequency.

Advanced Manufacturing Process
The complete screen body is machined on a gantry boring and milling mill, ensuring horizontal concentricity of bearing housings. Bearing housings are cast from special alloy steel for excellent wear and deformation resistance, eliminating frequent replacement.

Long-Lasting Structure
High-yield strength steel side plates and reinforced exciter mounts, optimized by finite element simulation, provide balanced strength and weight. The non-welded side plate construction uses HUCK rivets and hemming, eliminating welding stress, preventing frame loosening, and delivering superior fatigue strength.

Robust Frame
Finite element dynamic analysis optimizes the frame structure, enhancing strength to withstand greater exciting forces, improving stress distribution, and extending service life.

Stable & Reliable
The thin oil lubrication system offers better cooling, easier cleaning, low-friction oil film formation, and lower cost than grease lubrication. A special labyrinth seal prevents oil leakage, more than doubling bearing life.

Economical & Efficient
A 20° screen deck inclination promotes efficient large-stone screening and power utilization. The tripod structure separates the screen body from the frame, ensuring firm motor fixation and easier installation and transport.

Q: What is the main purpose of the XY Vibrating Screen?
A: The XY Vibrating Screen is designed to solve the common problems of traditional vibrating screens, such as low efficiency, short service life, and high pollution. It is specifically developed for mine crushing and screening applications, delivering high-capacity, high-efficiency screening operations.

Q: What makes the screen body so durable and long-lasting?
A: The screen body is built with high-yield strength steel plates and reinforced steel at the exciter locations. It uses HUCK rivets and hemming technology with no welding on the side plates, which eliminates welding stress and prevents frame loosening and deformation during long-term operation. Backed by finite element dynamic analysis, this design gives the screen body higher fatigue strength for outstanding durability.

Q: How does the XY Vibrating Screen achieve such strong vibration?
A: The equipment generates a powerful "Double Exciting Force" through a combination of shaft eccentricity and eccentric blocks. This produces a high vibration strength that fully ensures high capacity, high efficiency, and low cost in vibrating screening operations.
