摘要:
A method for determining quantity and/or a type of dust control agent for controlling dust of a bulk material or flowability thereof comprises dispensing a bulk material into an agitator and agitating the bulk material in the agitator to create airborne dust from the bulk material. A test method for determining a quantity and/or a type of dust control agent effective for reducing a quantity of airborne dust that separates from a bulk material during handling comprises: 1) dispensing a dust-containing bulk material into an agitator; 2) agitating the bulk material in the agitator to a degree sufficient to produce airborne dust from the bulk material; and 3) measuring a quantity of airborne dust produced from the bulk material; repeating steps 1), 2) and 3) after applying a particular dust control agent to said bulk material; and comparing the quantity of airborne dust that separates from the bulk material with and without the dust control agent.
