Product Introduction

Lab Scraper Type Disperser is a newly developed lab machine with dispersing and scraper function. During dispersing process, scraper rotates along the tank wall and generates a radial mixing flow. In addition, the PTFE scraper can scrape the materials on the tank off efficiently. It is good for the materials with mid-and-high viscosity and thixotropy property. The finished products can be discharged completely and the tank is easy to clean.

【Materials Viscosity】: ≤100,000 cps
【Production Capacity】: 5L
【Application Industry】: Prefect meet the requirement of dispersing and mixing from biology, pharmaceuticals, food, paint, ink, adhesive, pigment, pesticide etc. (Please click ‘Free Consultation’ for more information)
【Applicable Materials】: ood for all kinds of slurries with viscosity less than 100,000cps, and solid content less than 60%, such as emulsion paint, industrial paint, water-based ink, pesticide suspension, adhesive and etc anaerobic adhesive and etc.

    Product Advantages

    Higher efficiency, better quality
    The linear velocity is over 20m/s; it can disperse the powder into the liquid rapidly and efficiently.
    Easier and safer operation
    Adopt electrical push rod as lifting actuator, easy to operate and stable. The dispersing disc and scraper can be disassembled and replaced quickly, easy to clean.
    Clean discharging and easy maintenance
    The scraper perfectly solves the problem of materials staying on the wall and it is designed to be adjustable. It clings to the tank wall well under the counterforce of materials’ action, with long service life, easy to replace due to the bolts design.
    Customized Options
    Different options are available such as explosion-proof type, closed vacuum type, one machine with multi-tanks etc.. Material can be customized to be SS304 \SS321 \SS316L.

      • Co-axial Dual-shaft Hydraulic Lifting High Speed Disperser working principle

      Working Principle

      Through the high-speed rotation dispersing disc, the materials will become in annular form flow, resulting in strong vortex flow, which descend down to the bottom of the vortex in spiral state. During the process, materials are dispersed, dissolved, mixed and emulsified efficiently due to the strong shearing crash and friction among the particles.
      PTFE scraper rotates clinging to the tank wall to scrape the materials staying on the tank wall off and also enhances the materials circulation.
