The WQS Vibrator (also known as the WQS Vibrating Screen or Sieve Shaker) is a professional, laboratory-grade vertical particle analysis machine. It uses automated high-frequency electromagnetic vibration rather than rotary components to sift and classify granular materials.
Technical Specifications
- Measurement Range: Designed for ultra-fine particle analysis up to a 325 mesh threshold.
- Vibration Frequency: Operates at twin standardized speeds of 3,000 times/min 50Hz or 6,000 times/min 100Hz.
- Amplitude Settings: Infinitely and continuously adjustable from 0 to 3 mm.
- Vibration Modes: Configurable to fine/micro vibration, intermittent/intervallic vibration, or continuous vibration.
- Structure & Capacity: Features a vibrating plate that accommodates up to 8 stacking test sieves (standard 50 mm height each) plus a sieve-tray and head.
- Physical Footprint: Weighs approximately 20 to 25 kg with dimensions averaging 610mm × 390mm × 400mm.
Industrial Applications
- Pharmaceuticals: Controls the precise particle size distribution of raw powders to guarantee uniform tablet pressing or capsule blending.
- Food & Agriculture: Used on grains and cereals to isolate impurities or sort seeds to optimize germination consistency.
- Cosmetics: Separates pigment and base powder particles to achieve a silky, uniform texture in makeup formulations.
- Metallurgy & Chemicals: Screens plastic granules, chemical polymers, and metallic powders to improve raw material flowability during industrial molding and extrusion.
