According to different soil in varies areas, different kinds of plants absorbing fertilizer, calculating the proportion of materials. Machines mix mixtures, then the production can be kept for a long time.

   Mixing fertilizers must be granule uniformity, less water, granule intensity moderate, no agglomeration store. Every granule diameter is asked same, granules distribute symmetrically. So before mixing material. It is very necessary to analyze different material granules diameter distributing.

  The set designs novelty, utility and embodies the systems of elevating sending material. Exactly mixing, storing work and electronic control, which sending material system doesn't store material? Mixing system mix mixture well- proportionally, automatically packing.
