There are many factors that affect the production of asphalt batch plant-like aggregate moisture content, bulk density of aggregates, percentage of dust in the mix, ambient temperature, mix temperature, and altitude.

When the moisture content in aggregates is 3% or less than it does not affect the production. When the moisture content is more than 3% say 4% it will affect the production by 12% and you can expect the production to be around 88%. When the moisture content is at 5% the production will be 75% and when the moisture content is 7% the production will be down to 50%. Hence, we can easily say that as the moisture content increases, the production drops.
