Sanyuantang provides screening, feeding, conveying, and filtration equipment for chemical powders, plastic resins, pigments, industrial salts, fertilizers, and granular materials. Our vibrating screens and powder handling equipment are used to remove impurities, classify particles, and transfer materials between production stages.
We select equipment according to the material’s particle size, flowability, chemical properties, and required capacity. From standalone chemical vibrating screens to integrated powder conveying and screening systems, we provide equipment configurations for different chemical processing requirements.
Chemical Powder & Granule Screening Applications
Chemical materials vary in particle size, density, moisture content, and chemical properties. Some powders flow easily through a screen, while others are prone to clumping, static electricity, or screen blockage.
Sanyuantang provides screening and handling equipment for a range of chemical powders and granules, with machine configurations selected according to the material and its processing requirements.
Resins & Plastic Materials
PVC resin, polyethylene powder, polypropylene granules, masterbatch, and other plastic materials are screened to remove oversized particles, fines, and foreign material before further processing.
We use rotary vibrating screens for resin powder screening and linear vibrating screens for continuous plastic granule grading. Screen openings and discharge arrangements are selected according to the required particle size.
Chemical Salts & Inorganic Powders
Soda ash, sodium sulfate, potassium sulfate, calcium chloride, and other inorganic chemicals may form lumps during storage and handling. Screening helps remove these agglomerates and separate materials into the required size fractions.
For moisture-sensitive or corrosive materials, we also consider contact material compatibility, enclosed feeding, and equipment cleaning requirements.
Pigments & Carbon Materials
Pigments, carbon black, activated carbon, and other fine chemical powders can be difficult to screen because of their low bulk density, particle adhesion, or tendency to form agglomerates.
Ultrasonic vibrating screens can be considered for fine powders that repeatedly block conventional screens. We evaluate the material properties and required mesh before recommending a suitable screening method.
Mineral Fillers & Fine Powders
Calcium carbonate, silica, talc, glass powder, and other mineral fillers are commonly screened before blending, compounding, or packaging.
Screening removes coarse particles and unwanted material, while finer classification may require additional screening decks or ultrasonic assistance. We select the screen opening according to the required particle size rather than using a fixed mesh for every filler.
Fertilizers & Chemical Granules
Fertilizer granules, potassium sulfate, industrial salts, and other granular chemical materials often contain oversized pieces and fines after granulation, drying, or conveying.
Linear vibrating screens and multi-deck screening equipment separate these fractions before storage or packaging. Screen apertures and deck arrangements are selected according to the required granule size distribution.
Chemical Liquids & Slurries
Chemical solutions, liquid resins, and suitable industrial slurries may contain undissolved particles, agglomerates, or other solid impurities.
Sanyuantang offers vibrating filtration equipment for selected liquid processing applications. We consider viscosity, solids content, required filtration opening, and material compatibility when selecting equipment.
Common Challenges in Chemical Screening
Chemical screening performance depends on both the physical and chemical properties of the material. When consider the following problems when selecting screens, contact materials, and feeding arrangements.

Chemical Powder Conveying & Screening Systems
Chemical powder processing often involves several connected operations, including feeding, screening, conveying, mixing, and collection. Moving materials manually between machines can create dust and make continuous production more difficult.
Sanyuantang supplies screening and powder handling equipment that can be connected to existing production lines. We select the equipment arrangement according to the material, processing capacity, and available installation space.
Fine Chemical Powder Screening & Conveying Line
Fine chemical powders may require enclosed transfer between the feeding station, screening machine, and collection equipment. Bag Dumping → Vacuum Conveying → Vibrating Screening → Powder Collection The feeding station receives the material, while a vacuum conveying system transfers it to the vibrating screen. Oversized particles are separated, and accepted powder is collected for further processing. We configure the screen, feed connections, and discharge arrangement around the customer’s process and powder handling requirements.
Resin & Plastic Granule Processing Line
Plastic granules and resin materials often require screening after production or conveying to remove fines and oversized particles. Feed Hopper → Linear Vibrating Screen → Graded Material Collection A multi-deck linear vibrating screen can separate different particle size fractions, with individual outlets directing the material to collection containers or downstream equipment. For continuous production, we also consider feeding rate, screen inclination, discharge height, and equipment connections.
Fertilizer & Chemical Salt Grading Line
Fertilizer granules and chemical salts may require screening after drying, cooling, or other production stages. Feeding → Multi-Deck Screening → Size Separation → Collection The upper screen removes oversized material, while lower screens separate the required product fraction from fines. We can configure the screening area, number of decks, and discharge outlets according to the required particle size ranges and production capacity.
Equipment Materials & Safety Considerations
Chemical processing equipment must be suitable for both the material being handled and the operating environment. Contact materials, seals, electrical components, and dust control arrangements should be selected according to the actual application.
Carbon Steel & Stainless Steel Contact Parts
Carbon steel can be considered for suitable non-corrosive industrial materials where stainless steel contact surfaces are not required. 304 stainless steel is commonly used for general chemical powder handling. For applications requiring greater corrosion resistance, 316 or 316L stainless steel may be specified. We review the chemical composition, moisture, temperature, and cleaning requirements before confirming contact materials.
Corrosion-Resistant Equipment Options
Some chemical materials require additional protection against corrosion or chemical attack. Depending on the material and process, stainless steel, suitable polymer contact components, or other corrosion-resistant arrangements may be considered. Chemical compatibility should be checked for the screen mesh, seals, internal surfaces, and connected equipment before production.
Dust Containment & Explosion Protection
Fine chemical powders may generate airborne dust during feeding, screening, and conveying. Enclosed covers, sealed connections, and suitable dust collection arrangements help reduce powder escape. Some combustible powders also require specific grounding, electrical protection, and explosion prevention measures. We review the material’s safety data and installation requirements when determining the equipment configuration. Explosion-protected equipment must be specified and verified for the applicable hazardous area and operating conditions.
Chemical Liquid & Slurry Filtration
Chemical solutions, resin liquids, and industrial slurries may contain undissolved particles, coarse solids, or agglomerates after mixing. Vibrating filtration equipment can remove these materials before storage, further processing, or filling.
For low-viscosity chemical liquids, a vibrating filter can provide continuous separation through a suitable screen opening. For thicker slurries, filtration performance depends strongly on viscosity, solids concentration, and particle characteristics.
Sanyuantang can review the required filtration opening, liquid flow rate, contact material, and cleaning method to determine whether a vibrating filtration system is suitable.
