Channel Rubber/Bucker-Up Rubber. Channel rubber or bucker-up rubber, as it is frequently called, is the single most important factor in preventing “metal to metal contact” when wire cloth or other tensionedscreenmedia is used onvibrating screens. Channel rubber or bucker-up rubber acts as an “effective cushion” to prevent thesescreeningsurfaces from coming into direct contact with thesteel…[email protected]
Self-aligning spherical roller bearings developed specifically forvibrating screenapplications are used with positive grease lubrication and labyrinth protection. Single, fully machined eccentric shaft assembly with external eccentric weights to allow variation and adjustment ofvibrationfor maximum efficiency and flexibility of application.
Manufacturer ofVibrating ScreenMachines. Severe environment requiring special bearings. Pressure to reduce manufacturing costs. NSK employed specialvibratory screen bearings. NSK bespoke design for supply of complete housing, bearing and sealing solution. Resultantbolton complete solution. Reduced need for complex fitting.
Ourshaker screen boltsare threaded to the head and manufactured from grade #5 carbon steel. They are double heat treated to prevent stretching or breaking.Boltsare plated and available in 1/2″, 5/8″, and 3/4″ diameter in various lengths.
For the circularvibrating screen, the most common reason for the poor screening effect is the inadequate inclination of thescreensurface, so it is necessary to pad the back support. In practical application, the inclination angle ofscreensurface is more suitable when it is 20 degrees. ... Theboltshould be tightened in time at this time ...
Inclined Vibrating Screens. ... Self-aligning spherical roller bearings developed specifically forvibrating screenapplications are used with positive grease lubrication and labyrinth protection. ... Simple addition/subtraction ofbolt-on adjustment weights to both sides of the shaft will increase/decrease amplitude for specific requirements.
7 troubleshooting tips for vibrating screencommon problems. published date: 08-31-2019. Miningvibrating screenused in metallurgy, mining, coal, building materials, electric power, chemical and other industries, especially in the metallurgical industry. It is the most widely used screening machine under the blast furnace tank, coking plant and concentrating plant.
Pre-loadedbolts(or nuts) rotate loose, as soon as relative motion between the male and female threads takes place. This motion cancels the friction grip and originates an off torque which is proportional to the thread pitch and to the preload. The off torque rotates the screw loose, if the friction under the nut orbolthead bearing surface ...

Design the housing to be as symmetrical as possible, so it has the same thickness on both sides of thevibrating screenframe, in order to avoid housing deformation . Machine threads in the housing to make it easier when dismounting the housing from thescreenbody and the bearing from the housing by the use ofbolts(fig. 5 and fig. 6).
