I. Overview of the sieving machine

The sieve hole is not easy to block, the screening efficiency is high, the structure is simple, the weight is light, the power consumption is small, and the viscous or wet material can be sieved, and the application is wide; when the raw material contains clay, sludge or other impurities, it can also be The sieve was rinsed with pressurized water for wet screening. The sieving machine utilizes the relative movement of the bulk material and the screen surface to allow some of the particles to pass through the sieve hole, and divide the sand, gravel, gravel and other materials into different levels of vibrating screen powder mechanical equipment according to the particle size.

Second, the working principle of the sieving machine

The vibrating screen has an eccentric ring moving screen, an inertial vibrating screen and a resonance screen. The common feature is that the screen surface is subjected to high frequency and small amplitude vibration, so that the material on the screen surface is separated. The sieve hole is not easy to block, the screening efficiency is high, the structure is simple, the weight is light, the power consumption is small, and the viscous or wet material can be sieved, and the application is wide; when the raw material contains clay, sludge or other impurities, it can also be The sieve was rinsed with pressurized water for wet screening. The amplitude of the eccentric ring screen does not change with the amount of material on the screen and is suitable for the first coarse screen. The size of the mesh hole is generally 13 to 100 mm, and can reach 100 to 250 mm. The maximum feed size can reach 300 mm.

Third, the application of the sieving machine

The particle size of the sieve depends on the sieve surface, the sieve surface, the sieve and the sieve. The grid is suitable for screening large particle materials. The gap of the grid is 1.1 to 1.2 times the particle size of the sieve, and generally not less than 50 mm. The sieve is made of steel plate, and the hole is round, square or rectangular. The hole diameter is generally 10 to 80 mm. The service life is long and it is not easy to block. It is suitable for screening medium particles. The mesh screen is braided or welded by steel wire. The holes are square, rectangular or elongated. The common hole diameter is generally 6-85 mm. The long-shaped mesh hole is suitable for screening wet materials. The advantage of mesh screen is that the effective area is better. Big.
