Inventing the Sonic Sifter: How a New Cafeteria Changed the 筛分 Industry

Most materials have a lower size limit where sieving with a sieve shaker is no longer sufficient, and the agitation necessary for particle separation starts to break down and destroy some fragile materials. Particles in some substances resist separation and clump together due to electrostatic or moisture issues. For many years, these problems limited the effectiveness of measuring particle size by sieving. This article tells the story of how one man pushed 回来 those boundaries.

Dust and Noise: Can Better Equipment Help? 第2部分:噪音

High decibel levels can potentially be a dangerous element in your materials testing lab. In part two of our special series on workplace safety, you’ll discover some of the best ways to reduce noise levels during testing.

Dust and Noise: Can Better Testing Equipment Help? 第1部分尘埃

In part one of our special series on workplace safety, we take a look at how advances in materials testing equipment are minimizing potentially harmful exposure to dust in the lab.

Streamlining 骨料级配 Tests: Tips and 技巧

筛分 for particle size distribution is the primary test requested for construction aggregate samples. Whether field samples are being tested to evaluate a new aggregate source or just coming in as part of day-to-day quality control of production, particle size distribution is a primary consideration. If processing and sieving is not handled efficiently, it creates a 回来log.

Reference Materials for 测试筛子: Performance Testing for Quality

Reference materials for test sieves are used to evaluate and help ensure continued quality performance of sieves in compliance with ASTM or ISO standards. Sieve Verification Services provide further assurance of compliance through laboratory optical or microscopic examination.
