SZH-4 Reciprocating Automatic Sieve Shaker
Product Overview
The SZH-4 Reciprocating Automatic Sieve Shaker is a reliable laboratory screening instrument designed for accurate particle size analysis of powders, granules, soils, minerals, aggregates, and other bulk materials. It is widely used in industrial laboratories, geological surveys, medical laboratories, research institutes, universities, and quality control departments.
Powered by a durable single-phase motor, the machine drives an eccentric shaft to generate stable reciprocating motion, ensuring consistent and efficient sieving performance. Its built-in timer enables precise testing while minimizing human error and improving repeatability.
Compact construction, simple operation, and dependable long-term performance make the SZH-4 an excellent solution for routine laboratory sieve analysis.

Key Features
• Compact and robust mechanical structure
• Stable reciprocating motion for uniform screening
• Adjustable timer from 0–12 minutes with manual continuous operation
• Continuous operation exceeding 6 hours
• 40 mm reciprocating amplitude for efficient material separation
• Built-in overload fuse and zero-voltage protection
• Easy operation, maintenance, and reliable performance

Working Principle
The SZH-4 operates through a motor-driven belt pulley system connected to an eccentric shaft. As the eccentric shaft rotates, it drives a sliding rod that moves the sieve tray back and forth in a horizontal reciprocating motion.
This continuous reciprocating movement causes particles to pass through sieve openings according to their size, producing accurate and repeatable particle size classification.
The complete system consists of:
• Electric motor
• Driving pulley
• Driven pulley
• Eccentric shaft
• Sieve tray frame
• Vibration rod
• Support plate
• Electrical control system
