Physical Specifications For Granular Fertilizer And Soil

The uniformity index of a product is a measurement of the relative difference in size between particles. A UI between 40 60 is ideal for fertilizer the larger the number, the greater the uniformity, as this will help to ensure that particles are uniform mitigating potential segregation issues, but different enough within that uniformity ...

Velocity and uniformity of air circulation in conventional

Velocity And Uniformity Of Air Circulation In Conventional

This paper presents the results of a research of velocity of air circulation in the conventional kiln drying of sawn timber and its influence on the uniformity of final moisture content. The data showed that the air velocity between 0.8-1.2 m.s-1 is significantly lower than the one that is optimal for timber drying of coniferous species 3-4 m.s-1.
