GÜRSAN has been working on mineral processing technology
4 DECK VIBRATING SCREENS
While designing these screens Gür-San has used the most advanced technology in addition to its approximately 25 year experience and knowledge feedback. Designs have been executed through 3 dimensional CAD computer program, and critical components have been subjected to stress analysis against severe conditions under a computer program operating by integration to this program.
Gürsan make upper vibratory screens, in addition to great number of operational advantage, have increased also screening capacity and quality. As soon as the fed material contact with the rear surface of the screen, it is accelerated forward, which ensures that height of the material on surface of the screen quickly decreased and homogeneously spread over the screen surface. This operation causes great number of fine materials to be screened rapidly in the first meter and thus the load of the most loaded of the screen becomes rapidly distributed and balanced. Thereafter the remaining near size material which spread over surface of the screen getting slower has been effectively screened.
Vibration system has been contemplated to rise at higher revolutions required by effective screening and to be adjustable easily according to different conditions, and designed to permit easy and rapid replacement of defective components in case of maintenance. This system which provides effective oscillation consists of twin right hand side and left hand side vibration units and interim cardan shaft which makes to operate these two vibrators in synchronization and transmits the power coming from the motors to another. Disassembly and reassembly of these vibrator units take only several hours.
Modular vibrator which required to be replaced due to whatever reason may be replaced either by its spare kept in your stock or by any spare vibrator available at the stocks of Gür-San. Dismantled defective vibrator may be sent to Gür-San and thus you may have it to be maintained and repaired under one year warranty and under Gür-San’ s Quality Assurance. Thus, you would be capable of avoiding loss of time due to suspension at the Work Site and non-guarantied maintenance to be carried out at your Work Site in a dirty and inconvenient environment.
These vibrators are grease lubricated and may be equipped with automatic lubrication system optionaly.
All screens have been equiped with vibration dampers for eliminating excessive oscillation occurring at the time of starts and stops. During design of E Series screens safety of users and operational facility have been also taken into consideration. For this purpose a lot of details have been observed at the Work Site and eventual solutions have been brought. Safe guards of eccentric weights, V-Belts transmitting power of motors and cardan shaft have been so designed that they may be easily dismantled and reassembled and in perfect protection. Suspension springs have been protected with rubber hoses for safety and against materials that may be jammed therein.
In order to be able to replace sieves of screen easily, the spaces between decks have been kept high; on the other hand the fact that vibration unit is located at the top of the screen ensured both making maintenance of the unit easily and spaces between decks become rather comfortable.
Effective washing system has been also integrated into the screens; when requested, all of these models may be supplied complete with the said effective washing system.
Another feature which has been taken into consideration however is that decks are manufactured optionally according to both wire sieves of different types and modular polyurethane sieves to be used for abrasive materials. Precaution has been taken on surfaces against wearing by coating rubber on which abrasive materials may contact.
E02 (4,8 m2 ), E04 (8 m2), E05 (12 m2) and E14 (14 m2) screens are available on mobile chasis also. Both models are designed to set up at the site easly and rapidly. Their inspection platforms, stair cases and sliding front chutes are as practical as stationary ones.
The angles of the decks can be produced as banana type in the screen models of E05, E13 and E14. The modular deck angel is 18 degrees. It is possible to reach more efficent screening capacity by changing the deck degrees to 15, 25, 35 degrees.
