The processing accuracy of the cell plate will directly affect the verticality of the filter bag and the concentricity of the nozzle. The processing requirements mainly include three aspects for quality control: It is guaranteed that the spacing of the pattern holes will be controlled within 1 mm, and the processing of the collection bag […]…
The core of membrane technology is membranes. In general, the chemical properties and structure of the membrane have a decisive influence on the properties of the membrane separation. Therefore, it is required that the membrane material should have good film forming properties, chemical stability, resistance to acids, alkalis, oxides, and microorganisms.…
Pigment processing typically involves a chemical reaction to precipitate the metal oxides from suspensions of solvent . The resulting precipitate should be separated from the suspension in a solid / liquid separation . The filter cake is actually the product and this cake is typically washed to remove all traces of solvent mother waters. The […]…
Manufacturing and packaging within the Pharmaceutical industry can generate a variety of types of nuisance dust. Depending on the type, there may be concerns with cross-contamination with other products, GMP issues or occupational exposure limits to active pharmaceutical ingredients for plant workers.Donaldson have a wide range of dust collectors well suited to the Pharmaceutical industry […]…
Thermal Spray Thermal Spray or Metalising is a group of coating processes which deposits finely divided metallic or non-metallic materials in a molten or semi-molten condition on a surface/substrate to form a coating. The coating material may start out in the form of a powder, ceramic rod, wires, or even molten materials. The process has […]…
It is important in the process of chemical pulping indicates that the caustic used to dissolve the cellulose can be recovered due to environmental and economic considerations . If you use a plant pressure vessels for recausticization , they will need to effectively monitor water clarity comes from the units. This can be achieved by […]…
GRINDING Grinding operations employ abrasive grains in various forms for the removal of material and metal to produce of different types of surface finishes. Abrasive grains held together with a hard, durable bonding material make grinding wheels, abrasive stones, and sticks. Abrasives can also be applied on fibrous sheets, paper, or cloth with the principle materials being […]…
PROCESSES INVOLVING GRAIN DUST Most grain dust is created by material handling processes, which include: Dump pits Break milling Sifters / Sorters / Classifiers Elevator legs Bin / Silo loading Roller milling Conveyors Packaging Barge / Rail car / Truck loading Garner scales Drying Mixing bin venting Grain cleaners Hammer milling …
Introduction Mining processes vary widely depending on the material to be extracted , such as iron , copper and gold , and the nature of the deposit . These processes include conventional milling , grinding , and casting processes and leaching processes and extraction . All the above methods require significant amounts of process water […]…
