subject: Some Merits Of Jaw Plate Of Jaw Crusher [print this page] Jaw plate is an very important part of jaw crusher. Our jaw plate is manufactured with super high manganese steel, therefore this high quality jaw plate has a 50~100% longer service life than those made of traditional manganese steel. The special processing techniques ensure that our jaw plates has outstanding performance. The Jaw plate is the main spare parts of Jaw crusher. So the quality of Jaw plate appears especially important. Our company produces the high quality Jaw plate with the superior quality high-abrasive materials. Compared to similar products, our Jaw plate service life is above 30% and the expenditure is more economical and more convenient.
When the compound toggle jaw crusher is working, the points on the movable jaw often move in a plane motion, and their track is a closed curve and the track at the materials feeding mouth is in the shape of oval. The closer to the materials feeding mouth, the flatter and straighter the track will be. Along with the horizontal direction and the vertical direction, we get the displacement of the track S and H, and we call S as the horizontal throw of the movable jaw and H as the vertical throw of the movable jaw, and their ratio is the throw characteristic value of the movable jaw.
The main motion parameters of the movable jaw include the material feeding mouth, gravity and the horizontal displacement distance and vertical displacement distance of the material feeding mouth and the characteristic value of the movable jaw. These parameters influence the crushing ratio and production capacity of the compound toggle jaw crusher to a large extent. The throw of all points on the movable jaw and their characteristic value determines the performance of the crushing equipment. Because when the materials are being crushed, the bigger the materials are, the higher the amount of the compression needed will be, the horizontal throw should gradually decrease from the material feeding mouth and the discharging mouth. The vertical throw will rub and grind the materials, but too long vertical journal will lead to over-crushing of the materials and at the same time, shorten the service life of the movable jaw plate, for this reason, the vertical journal cannot be too long. Consequently, the characteristic value cannot be too high or too low. Then we can use the characteristic value to estimate the performance of the compound toggle jaw crusher. And it is necessary to analyze the characteristic value of the movable jaw plate.impact crushing machine:http://www.hx-crusher.com/n120.html
The horizontal journey of the movable jaw plate should be adjusted to be relatively long in order to make sure that there is sufficient crushing force for the crushing. In addition, the horizontal displacement distance should gradually increase from above to the bottom, and the feature of the relatively big vertical displacement of the discharging mouth ensures the smooth of the materials discharging. At the same time, the relatively high vertical displacement of the movable jaw plate often leads to over-crushing of the materials.
