According to the actual use of the flour mill, from the tensioning method and equipment of the nylon flour mesh, it can be divided into: manual method, self-tensioning method, mechanical tensioning method, and pneumatic tensioning method.
1. Manual method: Almost all flour mills use this method, which is completely based on operator experience and work responsibility. Because of its obvious defects, it has been basically abandoned by large and medium-sized flour mills, but in many small mills Still in use.
2. Self-tightening method: It is mainly used in the sieve frame of the powder cleaner. With its special structure, no external sieve device is used, and the sieve can be tightened only with special pliers. High square screen cores also use this tightening method (with special tools and special screen core structure design), but the proportion is not high.
3. Mechanical method: According to the actual structure, it can be divided into horizontal tightening, vertical tightening and a mixed type of two methods coexisting.
4. Pneumatic method: There are also two forms of horizontal tightening and vertical tightening. The horizontal tightening is generally a combined structure, which can be stretched at the same time as a single or double grid. The vertical tightening model is mainly accompanied by Oakrim From the production line, the number is small.
We mainly produce nylon flour mill mesh which is suitable for all of the stretching method.
