Overview of the centrifugal sieve
Rubber is an elastic soft object, so it is difficult to screen, which is easy to cause problems such as blocking the mesh. According to its characteristics, we have carefully developed the LXS-300 centrifugal sieve in combination with domestic and foreign technology. The sieve is also suitable for the classification of the dry powder material size in the chemical, plastic, and other industries, and effectively solves several major problems such as high fiber, high viscosity, high humidity, static electricity, easy agglomeration, and blockage of the mesh in the sieving process. The centrifugal force is generated by the rotation of the blade to throw the material outward, thereby achieving the purpose of sorting. The machine has the advantages of convenient disassembly and assembly, stable operation and strong practicability.
How the centrifugal sieve works
Centrifugal filtration is the centrifugal pressure generated by the suspension under the centrifugal force field, acting on the filter medium, so that the liquid passes through the filter medium to become the filtrate, and the solid particles are trapped on the surface of the filter medium to achieve liquid-solid separation; centrifugal sedimentation is utilized The principle of rapid sedimentation and stratification of the components with different density of suspension (or emulsion) in the centrifugal force field is mainly composed of shell, base, sieve drum, rotor and motor. The slurry enters the sieve drum through the feed port on one side of the outer casing, and the good slurry passes through the sieve hole by the pressure difference between the inner and outer sides of the sieve drum and the centrifugal force, and the coarse slag and the fiber bundle are intercepted in the sieve drum and discharged through the tail slurry port. Continue to rinse the sieve drum for several minutes until there is no slurry in the sieve drum.
Application of centrifugal sieve
Diffusion is unconditional and absolute. Diffusion is inversely proportional to the mass of the material, and the smaller the particle, the more severe the diffusion. The settlement is relative, and if it is conditional, it must be subjected to external forces to move. The settlement is proportional to the weight of the object, and the larger the particle, the faster the sedimentation. For particles smaller than a few micrometers such as viruses or proteins, they are in a colloidal or semi-colloidal state in solution, and it is impossible to observe the sedimentation process by gravity alone. The smaller the particles, the slower the sedimentation, and the more severe the diffusion phenomenon. Therefore, it is necessary to use a centrifugal machine to generate a strong centrifugal force in order to force these particles to overcome the diffusion to produce a settling motion. It is widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding sectors.
A drill can be divided into three categories: hand electric drill, Impact Drill, hammer drill. Minimum 1 hand Electric Drill: power, use scope is limited to wood drilling and when an electric screwdriver, part of the hand electric drill can according to the purposes to specialized tools, use and model more 2. The impact drill, impact drill impact mechanism have fangs and ball type two kinds Hand electric drill Hand electric drill . Ball type impact electric drill by the moving plate, plate, steel ball, etc. Dynamic plate through threads are connected to the spindle, with 12 steel ball; Fixing use pin fixed on the chassis, with 4 ball, under the influence of thrust, 12 steel ball along the four steel ball rolling, the carbide drill rotating impact movement, can on the brittle materials such as brick, block, concrete drilling. Release pin, make the fixing servo plate rotation, no impact, to make a general electric drill. 3. The hammer drill, electric hammer: can drill holes on any of the material, the most widely use scope. Three drill price from low to high alignment, function also is more, choose to knot
cordless drill, rechargeable drill
