New Leader - Size Grade Number (SGN) and Crush Strength Kit

The SGN and Crush Strength Test Kit helps determine particle size and hardness of the product being applied.

This determination is critical as material size affects the distance a material can be spread, and hardness affects how much energy (spinner speed) can be applied.

Instructions

Crushing strength is the minimum pressure needed to crush individual particles. Testing and knowing the crushing strength of a particular product will help determine maximum spinner RPM.

SGN (Size Grade Number) is the measurement of granule size in millimeters multiplied by 100. A product’s SGN will affect spread width.

It is highly recommended to perform a Catch Test, Crush Strength Test and SGN Scale Test prior to each season, before using a new product, or if a significant visible change has occurred with a product. Testing will define granular characteristics and help determine proper spinner settings for optimal product spread.
