In chemical pharmaceuticals, food processing, ceramics, plastics, and other industrial sectors, wet granulators mill wet powder raw materials into uniform granules through the coordinated swinging motion of a rotating cylinder and a sieve screen. This core process directly determines the quality of subsequent tablet pressing, compound molding, or material drying. However, due to frequent contact with wet, hot materials, chemical agents, and food-grade raw ingredients, key internal components of wet granulators-such as oscillating rotors, drive shafts, and screen support frames-are highly susceptible to wear and corrosion. Moreover, varying granule size requirements demand extremely high dimensional accuracy and material safety for these parts.
Hansheng Automation is dedicated to providing high-quality precision component custom processing services for wet granulation equipment. We can perform single-piece or small-batch precision machining of key components, including oscillating rotors, drive shafts, and custom sieve screen frames, based on the design drawings provided by our clients, utilizing food- and medical-grade stainless steel such as SUS316L and SUS304. We strictly control machining tolerances (e.g., maintaining shaft fit tolerances within ±0.01 mm) and utilize surface treatments such as mirror polishing and electropolishing to significantly reduce powder adhesion and extend the service life of accessories under demanding operating conditions.
Depending on the specific industrial application, our precision machined parts are engineered to perform optimally under various operating conditions:
Chemical and Pharmaceutical Industry: Wet granulation is typically used for granulating powder mixtures and crushing caked materials. The highly corrosion-resistant stainless steel parts we machine can effectively withstand chemical erosion from pharmaceutical ingredients, ensuring safety and hygiene in the production process.
Food Industry: Processing ingredients like candy, malt, and milk products requires extremely high surface cleanliness. Our precision-manufactured, seamless mixing and grinding accessories effectively prevent bacterial growth and accumulation.
Ceramics and Plastics Industry: Facing highly abrasive and hard ceramic powders or plastic compounds, the quenched, high-hardness, wear-resistant shaft sleeves and roller accessories we supply ensure running accuracy under long-term, heavy-load operations.
It is worth noting that wet granulation processes are generally not suitable for handling solid hard lumps, low-viscosity fluids, highly viscous slurries, or materials requiring ultra-fine grinding. To meet the precise mesh size required for different processes, users often need to match screens with various apertures. We can custom-machine quick-release clamps and screen support structures tailored to clients' specific process parameters, helping enterprises improve the overall efficiency of equipment maintenance and process switching.
