Product Overview & Core Advantages
The LF Series Thin Oil Lubrication Horizontal Vibrating Screen is a patented-grade screening equipment independently developed by Shandong Hengtai Intelligent Manufacturing Equipment Technology Co., Ltd. Relying on the utility model patent technology of "thin oil lubrication vibrating screen," it has become the core high-efficiency classification equipment for mining, building materials, infrastructure and other industries.
Why Choose Thin Oil Lubrication?
Traditional vibrating screens use grease lubrication, requiring frequent shutdowns for maintenance. The LF Series uses thin oil as the lubricating medium, achieving continuous lubrication of key components through a circulating lubrication system, delivering three major customer benefits:
Maintenance Costs Reduced by 50% — Significantly reduced wear on screen panels and exciters
Equipment Life Extended by Over 30% — Compared with ordinary vibrating screens
More Stable Operation — Noise ≤85dB, temperature rise controlled within 25℃
Applicable Operations: Coarse, medium and fine material classification, as well as dewatering and medium removal operations. The preferred customized screening equipment for quality control in large-scale production lines.

Working Principle
The LF Series Thin Oil Lubrication Horizontal Vibrating Screen is designed based on elliptical motion mechanics principles. The exciter drives the screen body to perform horizontal elliptical motion, achieving rapid material stratification on the screen surface:
Rapid Stratification — Elliptical motion causes large particles to quickly rise, while fine particles sink to contact the screen surface
The thin oil lubrication system simultaneously supplies oil to exciter bearings, forming an oil film protection, significantly reducing friction coefficient, and achieving continuous stable operation.

Frequently Asked Questions (FAQ)
Q1: What is the difference between thin oil lubrication and grease lubrication?
Thin oil lubrication uses engine oil circulation, with automatic filtration and cleaning, low friction coefficient, and good heat dissipation, suitable for continuous high-intensity operations. Grease lubrication requires manual periodic refilling, prone to loss at high temperatures, suitable for low-speed and low-load equipment. LF Series thin oil lubrication vibrating screens extend maintenance cycles by 3-5 times.
Q2: Is the LF Series suitable for processing wet materials?
Yes. The horizontal installation design is less prone to blinding, and the thin oil lubrication system has good sealing, capable of processing materials with moisture content up to 15%. For materials with higher moisture content, it is recommended to use with TS Series dewatering screens.
Q3: Is the equipment noise really below 85dB?
Yes. Actual measurement data shows that the LF Series operates at 78-83dB under full load, below the national occupational health standard (85dB). Suitable for plants near residential areas or noise-sensitive projects.
Q4: How to ensure long-term stable operation of the equipment?
We recommend: ① Use specified grade industrial gear oil; ② Check oil level and quality every 500 hours; ③ Replace lubricating oil every 2,000 hours; ④ Regularly check screen mesh tension. Hengtai provides remote diagnostic services, capable of real-time monitoring of equipment operating status.
Q5: Do you support overseas projects and customization?
Yes. Hengtai products are exported to over 50 countries in Southeast Asia, Middle East, Africa, and South America. Customization available according to voltage standards (380V/440V/480V), explosion-proof requirements, extreme climates (severe cold/high temperature/high humidity), etc.
