The crossbeam fracture because of getting an abnormal impact force. 2) Material deposit. Exciter beams often accumulate material deposit, if not cleaned up in time, it will cause the beam of vibrating screen parts wear severity and break. 3) Overload or load working.
The maximum deformation of grizzly bar is mainly affected by the vibration amplitude and the inclined angle of the vibrating screen. The optimization curve
The distance between the bearings is 3 metres, and the vibrating screen structure is made of welded and bolted steel parts. Shaft deflection and misalignment of supports under load require bearings that can compensate for misalignment. Spherical roller bearings are selected for this new vibrating screen , which is the typical solution. They can carry high loads and
01/07/2021· Problem 2: Deformation and fracture of screen frame. In the working process, the screen frame of the vibrating screen is constantly shaking, which is easy to cause bending fatigue, and local deformation or even cracking of the screen frame, side plate. If the screen frame is broken, the reasons may be as follows. 1. The sieve plate is too thin. 2.
01/09/2009· The enlargement of structure of vibrating screen will lead to the increase of vibration mass and exciting force. Dynamic load on the vibrating screen is also increased which will lead to a greater deformation, tear of the side plate, fracture of the crossbeam, and thus affects the service life of the vibrating screen seriously 1 3 .
The dynamic model of polyurethane screen deck in sieving is built. The maximum deformation of grizzly bar is studied and the section size of grizzly bar is optimized. The maximum deformation of grizzly bar is mainly affected by the vibration amplitude and the
07/08/2017· Vibrating screens are equipment used to separate and transport granulated materials in various processes throughout the mining,agriculture, pharmaceutical,food,andchemical industries. Although vibrating screens have many applications, problems such as adhesion, clogging, corrosion, wear, anduneven feed
A method for damping spring failure diagnosis of a large vibrating screen is proposed in 66 based on static deformation test. Influence of material and
25/04/2014· Abstract. Based on the statics theory, a novel and feasible twice suspended mass method was proposed to deal with the seldom studied issue of fault diagnosis for damping springs of large vibrating screen . With the static balance characteristic of the screen body/surface as well as the deformation compatibility relation of springs ...
