1) The screen standard of vibrating screen is too long, and the tension screw is not tight;

2）振動篩機張緊安排有問題，張緊板與篩機不配套、張緊板磨薄或變形；

2) There is a problem in the tension arrangement of the vibrating screen, the tension plate is not matched with the screen, and the tension plate is worn thin or deformed;

3）振動篩的篩網的彎邊形狀及標準與張緊板不配套；

3) The bending shape and standard of the screen mesh of the vibrating screen are not matched with the tensioning plate;

4）振動篩篩體焊接開裂引起篩體規劃性損壞，或是橡膠墊條磨損或有空當；

4) The welding crack of the screen body of the vibrating screen causes the planned damage of the screen body, or the rubber pad is worn or empty;

5）振動篩篩箱支撐條低于篩網，即支撐條和篩網有肯定間隔；

5) The support strip of the vibrating screen box is lower than the screen, that is, there is a certain interval between the support strip and the screen;

6）振動篩機的四處彈簧剛度不均勻，振幅過大。

6) The stiffness of the four springs of the shaker is uneven and the amplitude is too large.

一般，當石磨面粉加工設備篩網沒有拉緊或拉不緊的狀態下，構成的篩箱支撐條與篩網間發生了二次振動，繼而產生了互相碰擊，會導致構成的篩網呈直線狀有規則的開裂狀態。

Generally, when the screen of the stone flour processing equipment is not tight or not tight, the secondary vibration occurs between the screen box support bar and the screen, and then mutual collision occurs, which will lead to the linear and regular cracking state of the screen.

我國石磨面粉加工設備因其不斷改善的質量，逐漸優化的產品結構和科技水平的大力支持已經越來越能夠滿足石磨加工行業的需求。在此基礎上，企業要深耕現有的產品，提高產品的整體質量，在可靠性和技術升級方面下工夫，方能站穩陣腳，將食品機械國產化，使石磨面粉加工設備在國際市場闖出一片天地。

With the continuous improvement of the quality, the gradual optimization of the product structure and the strong support of the level of science and technology, China's stone milling flour processing equipment has been able to meet the needs of the stone milling industry. On this basis, the enterprises should deeply cultivate the existing products, improve the overall quality of the products, and work hard in terms of reliability and technology upgrading, so that they can stand firm and make the food machinery localized, so as to make China's stone flour processing equipment break into a world in the international market.
