Via several video calls, we discussed the details of the design of his 12 t/d double roller granulation line and then reached a consensus. His NPK fertilizer production line can produce 15 tons of fertilizer granules per hour. We used auto conveying machines to connect each NPK fertilizer making machine so that our buyers had no need to spend more on hiring workers. Last week, the client sent us a video of his NPK fertilizer production line that was producing fertilizer granules, and he looked quite delighted. We cordially hope that his fertilizer business will be brisk in the future.
