BASIC INFORMATION Installation ® The sieve shakers (Ro-Tap Models RX-29 & RX-30 & Coarse Model RX-812) must be mounted on a ® Ro-Tap Test Stand (R-40041), concrete foundation or heavy bench capable of supporting 200 lbs. Moderate tension of the mounting bolts is all that is required. Basic Operation ®...

Replace pedestal cover. Lubrication The Tyler Sieve Shakers require only minimal periodic lubrication. The units incorporate plastic and oil- impregnated bronze bearing materials, which are self-lubricating. A few drops of light oil or WD-40™ every six months is all that is necessary to prevent drying of the parts. Application of the same lubricants will suffice if a squeak or a drag should develop in the mechanism.

NEW HAVER TWINNUT CLAMPING SYSTEM The new ‘Haver TwinNut’ clamping system perfectly combines the advantages of the previous Classic and Easylock Systems Function: The sieve is fixed using the nuts in the same way as the Classic system (1.0 + 3.0). Varying heights of the sieve tower are achieved by opening the TwinNuts (2.0).

TEST SIEVE ANALYSIS Test Equipment Test sieves “nest” together to form a “stack” of sieves. In most sieving tests the 8 inch diameter sieve is used. A test sieve shaker that provides both circular and tapping energy is recommended. Uniform mechanical motion will provide the most consistent results.

The key to successful, repetitive particle analysis is developing standard testing procedures. Basic Elements of Testing 1. Sample Preparation. 2. Test sample sizes or weights. 3. Test Equipment. 4. Testing times or intervals. 5. Recording results. Sample Preparation When deciding how much material to test, consider the type of material, screen ability of the material and the range of particle sizes.

Static Electricity Some materials generate static electricity during the dry sieving process. When particles “charge” themselves as they come in contact with other particles, they stick to the metal frame and cloth of the sieve. This prevents you from obtaining accurate results. As a suggestion: ...
