Linear vibrating screen and vibro sifter for screening tea

Tea is a kind of drink in people's daily life, which contains a variety of beneficial ingredients and has health benefits. In the processing and production of tea, it is necessary to use a vibrating sieve to screen and remove impurities to improve the quality of the tea, and to achieve a refreshing and smooth taste. Fired tea is graded & sifted according to their sizes & shapes as trade demands all the variety of tea from the most expensive to affordable tea sachets.

Tea is a kind of drink in people's daily life, which contains a variety of beneficial ingredients and has health benefits. In the processing and production of tea, it is necessary to use a vibrating sieve to screen and remove impurities to improve the quality of the tea, and to achieve a refreshing and smooth taste. Fired tea is graded & sifted according to their sizes & shapes as trade demands all the variety of tea from the most expensive to affordable tea sachets. Screening and grading tea is a crucial step in the tea processing process. Linear vibrating screens and vibro sifters are commonly used equipment for tea screening.

The following are two common vibrating screen for screening tea.

1.Vibro sifter

The vibro sifter is used as an excitation source by an upright motor. When the vibro sifter is started, the eccentric weights installed on the upper and lower ends of the motor convert the rotary motion of the motor into a horizontal, vertical, and inclined three-dimensional motion. The movement is transmitted to the screen surface. In this process, the fine slag of tea leaves smaller than the pore size of the sieve surface falls through the sieve hole to the lower layer, and becomes the undersize material. The tea leaves larger than the pore diameter of the sieve surface are discharged from the discharge opening after continuous jumping movement, and the weights of the upper and lower ends are adjusted by adjusting The phase angle of the hammer can change its trajectory on the screen surface to achieve the purpose of screening.

Dahan vibro sifter  has high screening efficiency, the screen is not blocked, the powder is not flying, the sieve is fine to 500 mesh (28 microns), and can be designed with 1~5 layers of screen surface according to the screening yield of tea leaves. The fully enclosed structure has no dust and dust during the tea screening process, and is equipped with a special screen cleaning device (bouncing ball), which can reduce the problem of blockage of the tea during the screening process and improve the screening efficiency.

2.Linear vibrating screen

The linear vibrating screen uses a vibrating motor as the vibration source. When the two vibrating motors rotate synchronously or in opposite directions, the exciting force generated by the eccentric block cancels each other in a direction parallel to the motor axis, in a direction perpendicular to the motor shaft. Stacked as a combined force. The two motor shafts have an inclination angle with respect to the screen surface. Under the combined force of the excitation force and the gravity of the tea leaves, the tea leaves are thrown forward and linearly moved on the screen surface, thereby completing the screening and grading of the tea leaves, which is very suitable for the automatic operation of the assembly line.

Dahan linear vibrating screen has a maximum meshing capacity of 400 mesh, adopts fully enclosed structure, no dust overflow, automatic discharge, and is more suitable for 24-hour assembly line operation. Linear vibrating screen has 1~5 layers of screen design, most screening Out of 6 different sizes of tea, the screening effect is significant, and the yield is 0.12~20t/h.

The above is about the selection of tea vibrating screen. The specific vibrating screen needs to be selected according to the user's screening requirements and actual conditions.
