Analysis and Control of Rate and Uniformity for Granular Fertilizer Application Systems
Abstract
dc:descriptionA comparison was made between the spinning tube method discussed in this paper and a rheometer method. In the latter method, the particles are fixed in placeholders, and a spinning disc is kept in contact with them under a controlled normal force. The measured torque on the disc is then a measure for the friction coefficient. Data for the same fertilizer materials Ammonium Nitrate and Potassium Chloride indicated that the rheometer is not a good instrument to obtain friction coefficients with practical value, whereas the data from the spinning tube device is consistent with measured spread patterns.
