Product Details
The TQLZ Series Vibration Separator is a high-performance screening machine designed for cleaning and grading granular materials in grain processing facilities. Widely deployed in flour mills, rice mills, feed plants, oilseed processing facilities, and food manufacturing operations, this vibrating separator effectively removes impurities across multiple size fractions. Through precise screen selection, the TQLZ series accommodates wheat, maize, rice, oilseeds, and other granular commodities.
The machine employs a dual vibration motor drive system that generates controlled linear motion, ensuring consistent material distribution across the screen surface. Proven removal efficiencies include 65% for silt, 70% for light impurities, and 35% for barnyard grass seeds. Built with durable steel screens featuring cross-punched holes for maximum open area, the unit incorporates a self-cleaning rubber ball system that prevents screen blinding and maintains performance during continuous operation. With capacities ranging from 2 to 30 tons per hour across nine models, the TQLZ series offers scalable solutions for operations of any size.
Key Features
Proven High-Efficiency Impurity Removal with Optimized Screen Design
The TQLZ vibration separator delivers measurable cleaning performance through scientifically engineered screen design. Screens are fabricated from thin steel sheet with cross-punched hole arrangements that maximize open area while maintaining structural integrity. This configuration allows more material to contact the screen surface per unit time, improving overall throughput and separation efficiency. Field-validated removal rates demonstrate the machine's capability: 65% removal of silt and fine sand, 70% removal of light impurities including chaff and dust, and 35% removal of barnyard grass seeds—common contaminants that affect grain quality and downstream processing.
For applications requiring finer separation, multiple screen mesh options are available. The combination of optimized hole geometry and precise vibration parameters ensures that clean product advances while contaminants are effectively rejected, protecting milling equipment and improving final product purity.
Self-Cleaning Rubber Ball System Prevents Screen Blinding
Screen blinding—the clogging of screen openings by near-size particles or sticky materials—is a common challenge in continuous screening operations. The TQLZ series addresses this with an integrated self-cleaning system featuring medium-hardness rubber balls positioned between the screen layers. As the machine vibrates, these rubber balls bounce against the underside of the screen surface, dislodging particles that would otherwise become trapped. This continuous cleaning action maintains open screen area throughout extended operating cycles, preserving both throughput and separation efficiency.
Unlike mechanical screen cleaners that add complexity and maintenance requirements, the rubber ball system operates passively without additional power consumption or moving parts. For high-volume operations processing materials with variable moisture content or those prone to clogging, this self-cleaning capability significantly extends the interval between manual cleaning interventions and ensures consistent performance.
Dual Vibration Motor Drive with Synchronized Operation
The TQLZ series is powered by two vibration motors that operate from a shared terminal block, ensuring synchronized start-up and consistent vibration amplitude across the entire screen surface. This design eliminates phase mismatch issues common in systems with independent motor controls, resulting in uniform material distribution and predictable separation patterns. The motors are characterized by stable running characteristics, low noise output, reduced risk of electrical leakage, and extended service life compared to single-motor or mechanically-driven alternatives.
The vibration amplitude can be adjusted by modifying the position of external eccentric weights, allowing operators to fine-tune machine performance based on material characteristics—higher amplitude for coarse, free-flowing materials and lower amplitude for fine or delicate products. This flexibility enables the same machine to perform effectively across different grain types and cleaning applications.
Quick-Change Screen Frame with Tool-Free Access
Maintenance efficiency is critical in facilities where changeovers between different grains or cleaning objectives occur frequently. The TQLZ series features a screen frame clamping system secured by hexagon handle locks that can be operated without specialized tools. This design reduces the time required for screen inspection, cleaning, or replacement from hours to minutes. When switching between crops—such as from wheat to rice or corn—operators can quickly install screens with appropriate mesh sizes to achieve optimal cleaning results.
The accessible screen frame design also facilitates routine inspection of the rubber ball cleaning system, allowing operators to verify ball condition and replace worn components before they affect performance. Combined with the self-cleaning system that reduces manual cleaning frequency, this quick-change capability minimizes downtime and supports flexible production scheduling.
Low-Maintenance Design with Imported Vibration Isolation Components
The TQLZ vibrating separator is engineered for reduced operational costs through thoughtful component selection. The machine employs imported rubber springs for vibration isolation, which provide consistent damping characteristics over extended service life while transmitting minimal vibration to the supporting structure. Unlike steel springs, rubber isolators require no lubrication and are less susceptible to fatigue failure under continuous operation.
The entire system features no lubrication points, eliminating the labor and consumable costs associated with regular greasing schedules. This design approach results in maintenance costs that are significantly lower—typically 30-50% reduction—compared to conventional screening equipment with multiple moving parts and lubrication requirements. For facilities operating multiple shifts or processing abrasive materials, these maintenance savings accumulate rapidly while ensuring consistent machine availability.
Versatile Application Range with Multiple Model Capacities
The TQLZ series is available in nine model sizes, offering capacities from 2 to 30 tons per hour to accommodate facilities ranging from small-scale mills to large industrial processing plants. Model selection is based on required throughput and screen area, with options including TQLZ40×80 through TQLZ150×270. The machine's versatility extends beyond grain processing to applications in feed manufacturing, oilseed processing, food ingredient production, and chemical industries where granular materials require classification or contamination removal.
For facilities with specific requirements, the separator can be configured with optional features including stainless steel construction for food-grade or corrosive environments, full dust enclosures for emission control, and multi-deck configurations for simultaneous coarse and fine separation. This application flexibility makes the TQLZ series a standard solution for quality-conscious processors across multiple industries.
