A World Standard
In 1910 Tyler introduced a scientifically designed testing sieve series known as the Tyler Standard Scale Sieve Series. This was the foundation for the development of ASTM E-11 used in particle analysis today and would become a staple of W.S. Tyler’s reputation.
The principle of this sieve series became so essential, that it was adopted as a national standard by the United States and many foreign countries. Certain sieves were proposed as the basis for an international sieve standard.
To meet the need for faster, more reliable means of testing, Tyler developed the Ro-Tap Sieve Shaker in 1914. The Ro-Tap provided a means for exact duplicating test results between different laboratories. The original W.S. Tyler Ro-Tap is the industry standard for consistent, repeatable particle size testing.
Around the World
In the early 1900’s W.S. Tyler expanded its markets across the globe where materials were mined or screened – the tin mines in the Far East, the diamond mines in Africa, the flour mills in China, the coffee hulling plants in Brazil are just a few examples.
In 1958, Tylinter (W.S. Tyler International) was founded which was a joint venture between W.S. Tyler, Cleveland, Ohio, U.S.A. and Haver & Boecker, Oelde, Germany. This launched the company into a true two-way international trade
