Fine Grinder

Model WFJ series fine grinder or Model CWFJ series super fine grinder consists of three parts i.e. main machine, auxiliary machine and electric control. lts features are compact in design, reasonable in structure. lts principle is using air to chose and no sieve or screen. Being installed grading mechanism inside the machine, the crushing and grading can be finished at the same time. When use negative pressure to transport in the operation of crushing, the heat produced from the chamber will be removed continuously . Therefore it can also be suitable for crushing thermal sensitive raw materials. The scope of application of machine is wide. lts productive process is continuous and its size of granuIe can be adjusted. It can crush and grade many raw materiaIs such as chemicals, foodstuff, medicines, cosmetic, dyestuff, resin, shell materials and so on.

The spray dryer is the widest used technology in the liquid shaping technology and in the drying industry. It is most suitable for producing powder, particle, or block solid products from materials of solution, emulsion, soliquoid and pumpable paste states. Therefore, when the particle size and distribution of the final products, their residual water contents, the stocking density and the particle shape meet the precision standards, the spray drying is one of the most desired technologies.Features1.High speed of drying. After the spraying of he material liquid, the surface area of the material will be increased greatly. In the hot-air flow, 95%-98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.2.It is especially suitable for drying the heat sensitive materials. It's final products own the good uniformity, mobility, dissolving capacity. And the final products are high in purity and good in quality.3.The production procedure is simple and the operational control is easy. The liquid with the moisture contents 40-60%(for special materials, the contents may reach 90%) can be dried into power or particle products once a time. After the drying, there is no need for smashing of sorting, so as to reduce the operation procedures in the production and enchance the purity. The product particle diamenters, looseness and water contents can be adjusted through changing the operation condition in a certain scope. It is very convenient to carry out the control and management.
