Rectangular Vibrating Screen

Stop losing production time to inefficient screening. The DZSF Series Rectangular Vibrating Screen is a high-performance linear motion screening equipment engineered for classification, grading, impurity removal, and dust elimination of dry bulk materials. Whether you are processing chemical powders, food ingredients, or mineral materials, this Rectangular Vibrating Screen delivers consistent classification accuracy with minimal maintenance requirements.

Based on extensive field applications, this Rectangular Vibrating Screen has been proven to effectively handle materials ranging from fine powders to granular products up to 10mm with consistent performance in continuous 24/7 production environments. The Rectangular Vibrating Screen is suitable for materials with particle sizes from 0.074mm to 10mm and moisture content below 7%.

Working Principle 

The DZSF Series Rectangular Vibrating Screen is driven by two vibrating motors that rotate synchronously and in opposite directions. The excitation forces cancel each other out parallel to the motor spindle while combining into a single resultant force perpendicular to it, causing the screen box to vibrate in a linear trajectory.

Material is thrown upward and propelled forward in a straight line, allowing smaller particles to pass through while oversized particles are conveyed to the discharge end. The screen frame can be adjusted to various inclination angles to fine-tune material flow speed.

Structure Composition 

Screen Box: high-strength steel plate construction.

Screen Mesh: woven wire mesh (AISI 304/316) or perforated plates.

Vibration Motors: dual motors with synchronized reverse rotation.

Motor Pedestal: supports motors with adjustable positions.

Damping Springs: rubber isolation springs for vibration absorption.

Support Bracket: stable foundation, must be mounted perpendicular to ground.

Discharge Ports: customizable positions (left, right, forward, or downward).

Selection Guide 

When selecting a Rectangular Vibrating Screen, consider:

Material characteristics – particle size, moisture content, bulk density, abrasiveness

Screening objectives – safety screening, grading, dust removal, or dewatering

Configuration – deck layers, mesh size, construction material, inclination angle, cleaning system

Rectangular vs. Circular Vibrating Screen

Aspect	Rectangular	Circular
Motion	Linear	Circular/elliptical
Application	Grading, classification, conveying	Fine screening, dewatering
Capacity	Higher for dry materials	Better for finer separation

Installation & Maintenance 

Installation: Install on level concrete foundation；Ensure damping springs are perpendicular to ground；Re-tighten connecting screws during first three days of operation.

Daily Inspectio: Check screen mesh for damage;Listen for abnormal noise;Verify motor temperature.

Weekly Maintenance: Tighten bolts;Clean screen surface;Inspect discharge ports.

Monthly Service: Check motor bearings;Measure vibration amplitude;Inspect screen frame for fatigue.

Troubleshooting : Symptom: Material buildup.

Cause: High moisture, clogging.

Action: Install cleaning system.

Symptom: Reduced efficiency.

Cause: Worn mesh or incorrect angle.

Action: Tighten bolts or replace springs.

Frequently Asked Questions 

Q: What is the maximum feed size?

A: Up to 10mm. Larger materials may require pre-crushing.

Q: Can the screen mesh be customized?

A: Yes, mesh size and material (AISI 304/316, polyurethane) can be tailored.

Q: How many screen layers are available?

A: 1 to 8 layers for multi-fraction separation.

Q: What is the difference between circular and Rectangular Vibrating Screens?

A: Rectangular screens provide linear motion for higher throughput in dry classification. Circular screens offer circular motion better suited for fine screening and dewatering.
