How to relieve jaw crusher weight?

According to related statistics, domestic jaw crusher machine weight is generally higher than foreign specifications crusher. How to reduce jaw crusher weight is an important topic for crusher enterprises.

Rack structure designed unreasonable is also an important reason for weight increase. The rack-structure design should first is based on the force, under the conditions to meet the strength, stiffness, and seeks to reduce the weight. Moving jaw crusher greater weight parts, and complex structure. The moving jaw structure design should be based on moving jaw force, under the conditions to meet the strength and stiffness requirements, and minimize weight.

The movable jaw stiffener arrangement design requirements shall be the force. The jaw crusher existing to strengthen tendons horizontal thickness from top to bottom thickness is the same. Is in line with the conditions of the force, but also to meet the requirements of light weight, variable thickness can be used to strengthen the tendons. That rely on the the ribs thickness of the upper (head), the more down the greater thickness.
That is, change the original rectangular reinforcement rib is trapezoidal ribs, as this would reduce the weight of the movable jaw and to ensure that there is sufficient strength. The moving jaw between the two bearing parts of the wall thickness can be moderate thinning, in order to reduce weight.

In addition, the rack should be strengthened, moving jaw Finite Element Method and rack moving jaw the Finite Element optimization design, achieve the rack, moving jaw light weight and has a high degree of reliability.Other, crushing chamber crusher dynamic balance, etc., can make use of a computer-optimized design. In short, modern design methods should be used instead of the conventional design method.

Furthermore, due to factors such as welding, casting, heat treatment process will impact crusher.
So, we should raise the level of manufacturing process design and the use of hydraulic adjustment of the discharge opening and hydraulic insurance gradually so that domestic jaw crusher to achieve world-class level.
