Application solutions:  
Application 1:
Manufacturers of powdered detergents need to eliminate oversize granules, which detract from eye appeal of the product and retard the rate at which they will dissolve. Since the detergent is bone dry at time of scalping, dust and screen capacity are a problem with other types of sieving devices. Chenwei vibrating screen can handle the capacities that detergent manufactures require, while holding oversize material to a manageable level. The use of metal covers and flexible spout connectors also eliminate the dust.    
Application 2:    
Processors of Potassium Iodide require a sizing process that will allow them to effectively market their product to various industries determined by the particle size of the material. After an extensive extraction process to get to the pure white potassium iodide, the material is passed through a pulverizer and sent to a Chenwei vibrating screen where three separations occur. The largest of the cuts is marketed to the chemical industry, the middle cut to the pharmaceutical manufacturers, and, finally, the smallest cut to the cattle feed mineral supplement producers.    
Application 3:    
The production of high-quality citrus juice requires the separation of the pulp, seeds and rag (peel membrane) from the juice itself. Juice enters the top screen and flows through to the bottom. The top screen separates out the larger seeds and portions of rag; the second screen separates the desirable large juice sacs and passes the small embryo seeds and undesirable fine pulp; these latter are caught by the third fine mesh screen. The Chenwei vibrating screen are able to provide a higher quality juice by eliminating various stages of the process which necessitated pressure and maceration of the pulp.    
Application 4:    
Producers of commercial grade uniform plaster and paint aggregate use raw, crushed perlite ore from the mines. The expanded material is air separated, and companies wished to grade the fines from the air separation. After disappointing experiences with several conventional screens, CHENWEI installed a standard production-size round separator. Demands for fine aggregate of this grade are apt to change radically with building styles and finishes. The versatility of the CHENWEI vibrating screen makes it relatively easy to consistently meet such changing demands.    
Application 5:    
In the processing of drug powders, pharmaceutical companies have difficulty with stamping tablets due to the fines present in tablet granulations. CHENWEI was able to eliminate this problem, while improving the quality of the product, increasing production rate and cutting costs. A round separator now removes all fines from granular material, resulting in a more uniform and better appearing tablet. There are also fewer product rejects. CHENWEI Separators have been so successful in the dry screening that the machines are now used for screening liquid pharmaceuticals to remove undissolved particles of medicaments.  
Application 6:    
Producers of granulized powders for drug manufacturers at one time used a manually operated device to size pharmaceutical powders. This was a costly, timely, cumbersome, and inaccurate process. A CHENWEI Separator provided a more judicious, simple and accurate process with minimal expense. All powdered drugs are quickly screened in minimum time with complete accuracy. Additionally, the separators are available with casters for easy movement around a laboratory setting to perform a wide variety of pharmaceutical screening.    
Application 7:    
Some camera manufacturers require a method of removing undesirable fines from reground plastic used in molding parts for camera products. Fines in regrind plastic may cause one or more problems: a) streaking or discoloration of the finished part; b) variations in particle size, and, therefore, in bulk density, cause shot-to-shot variations in the mold; c) because of a lower melting point, fines tend to create gassing when temperatures are elevated to levels sufficient to melt larger particles. A CHENWEI Separator is used to screen the reground plastic, separating the fines out and sending the clean product back to the molding machines.  
Application 8:    
In the production of Polyethylene and Polypropylene, CHENWEI vibratory separation equipment is widely used in the process. Located downstream from the extruder and cutter, round or rectangular separation equipment is used to remove the "longs", "angel hair", and "streamers" from the plastic pellets. The plastic pellets of these products are used to manufacture an abundance of plastic products ranging from water bottles to computer casings.
Application 9:  
Many manufacturers face the serious problem of what to do with the effluent discharge associated with their processes. This is problematic in almost every industry known, and the paper industry is no exception. For instance, paperboard manufacturers have to deal with large amounts of fibrous material contained in the black liquor pressed from wood chips. This material needs to be cleaned up before they can introduce the water back into the sewage system. With CHENWEI Round Separators, the large amounts of fiber getting into the sewers have been eliminated and the B.O.D. reduced. At the same time, the valuable fiber is being recovered for reuse in the paperboard process.  
Application 10:  
Kaolin is fine white clay that is widely used in the making of paper and many other products. Screening is a very important component of the process flow from mining to marketable slurry. Typical Kaolin process flow starts with mining the clay. Large loads of clay are washed and rocks are removed. The hydrated clay goes to CHENWEI Hydrocyclones to remove sand particles. The slurry is then screened on CHENWEI EM3 Rectangular Separators and sent via pipeline to the next stage.    
Application 11:  
Manufacturers of tableware and other ceramic dishware were in need of a more efficient and effective screening system for their ceramic body and casting slips. The rotary screening systems previously used occupied a tremendous amount of space and were extremely inefficient. CHENWEI Separators have replaced these other style separation systems to provide a more efficient separation process in a fraction of occupied floor space.  
Application 12:  
A manufacturing company in Eastern Pennsylvania screens an unusually difficult talc-pyrophyllite wall tile body slip. It contains large particle sizes of raw materials and has a plate-like nature. Their capacity was unsatisfactory on conventional screens. The company found the CHENWEI Separator to be far superior to any screen previously tried on their wall tile slip screening. There was less vibration transmitted to the building; more quiet operation; easier to clean; screening action easily adjustable; easy screen changing; greater capacity; and more.  
Application 13:  
Manufacturers of products such as capacitors, spark plugs insulators, and more require a high quality ceramic to use in their processes. The finer the ceramic particles are the higher the quality of the product. CHENWEI Vibro-Energy Grinding Mills use a low-energy grind to reduce the size of the particles, sometimes to as low as sub-micron ranges when required. Unlike some of the other high-energy grinders, CHENWEI mills are able to keep the particle distribution to much tighter tolerances, all while containing the process in an easily accessible environment.    
Application 14:  
Manufacturers of powder paints for the automobile industry were having problems keeping their screens clear, significantly reducing their throughput. After trying various basic screen cleaning devices, they contacted CHENWEI. After several tests in the CHENWEI lab, it was determined that the best course of action would be to add a Sono-Energy System to their round separator. The secondary vibration to the screen helped to clear the screen openings of any particles which had accumulated in the mesh. The blinding, and thus, the throughput issues were resolved simply by adding the ultrasonic technology to existing machines.
