AI Technical Summary
Existing slow-release fertilizer production equipment made from medicinal herbs is prone to wear and pulverization under long-term chemical erosion from contact with medicinal herb powder and excipients, resulting in impurities falling off the inner wall and contaminating the product. Furthermore, the unreasonable design of the gaps between the internal components of the equipment makes it easy for them to clump and become stuck, causing production blockages and low efficiency.
The inner walls of the material preparation and storage cylinders are coated with a polytetrafluoroethylene (PTFE) anti-powdering coating. Combined with a servo motor-driven rotating shaft and extrusion rollers, the material is prevented from clumping through directional extrusion molding and rubber ring ejection design. At the same time, an anti-clogging mechanism is equipped to automatically handle clogging problems.
It significantly reduced the incidence of blockage failures, improved the continuity and stability of production, reduced the frequency of maintenance, ensured product purity and production efficiency, and extended the service life of the equipment.
