Environmentally Friendly Enclosed Standard Test Sieve Shaker Machine for Dust Free Laboratory Particle Size Analysis

Product Overview

This sealed, environmentally friendly test sieve shaker represents an advanced generation of laboratory particle sizing equipment engineered to resolve the traditional operational challenges of ambient noise and fugitive dust generation. Built upon a heavy-duty industrial foundation, the system combines high-frequency circular swinging with powerful vertical tapping mechanics to deliver rapid, highly reproducible fractioning of granular materials and powders. By fully enclosing the shaking mechanism inside a reinforced sound-insulated cabinet, this unit prevents sample loss, eliminates cross-contamination, and maintains a pristine testing environment within demanding laboratory facilities.

Designed for rigorous analytical quality control and material research, this equipment is extensively deployed in coal assaying, geological exploration, extractive metallurgy, chemical processing, cement manufacturing, and civil engineering material testing. It processes a wide diversity of sample matrices ranging from coarse mineral ores to fine synthetic chemical powders. The system accommodates standard laboratory sieve stacks, allowing laboratory technicians to execute repeatable particle size distribution assays under standardized, tightly controlled laboratory conditions.

Engineered to meet stringently elevated environmental and occupational standards, this equipment incorporates an advanced sound-dampening acoustic enclosure that attenuates mechanical noise by 40% during operation compared to unsealed conventional sieve shakers. The precision-machined heavy base structure, solid mechanical linkages, and smooth transmission system ensure outstanding long-term operational stability without structural drift or floor vibration. Furthermore, the unit features seamless integration points for laboratory dust extraction systems, enabling continuous dust-free operation even when processing ultra-fine or hazardous powdery materials.

Key Features

• Acoustically Insulated Sealed Housing: Features an advanced sound-dampening cabinet structure that shields up to 40% of the mechanical operational noise, establishing a significantly quieter and safer working environment in analytical laboratories.
• Dual-Action Rotary and Tapping Motion: Combines a 221 cycles per minute circular gyratory swing with a 147 impacts per minute vertical tapping action, continuously clearing screen aperture blinding and accelerating particle throughput across fine mesh layers.
• Dust-Free System Integration: Equipped with sealed cabinet connection ports designed for direct integration with laboratory dust extraction and collection systems, preventing fugitive dust emissions during aggressive sifting routines.
• Integrated Automatic Timing Control: Incorporates a precise, user-configurable timer adjustable from 0 to 60 minutes with an automatic shut-off feature to ensure exact duration repeatability across sequential sample batches.
• Heavy-Duty Cast Iron Base: Engineered with a dense, low-center-of-gravity cast base that effectively dampens dynamic kinetic forces, maintaining absolute chassis stability and preventing equipment drift during high-load test cycles.
• Flexible Sieve Stack Clamping Assembly: Features quick-acting, height-adjustable vertical clamping rods that accommodate sieve stack heights up to 440 mm, applying uniform downward force to prevent sieve shift or sample leakage.
• Precision Machined Transmission System: Powered by an industrial-grade 0.37 kW motor coupled to heavy-duty mechanical linkages, delivering consistent rotational torque and impact energy under continuous duty conditions.
• Ultra-Fine Screening Capability: Optimized to work seamlessly with fine woven wire mesh sieves down to 400 mesh, delivering sharp fraction cut-offs with minimal material retention on intermediate screens.
