The AVRK-4 round vibrating screen (vibrating apparatus) is a new development from KB Intel. This model is a four-deck vibrating apparatus for screening catalyst systems into target fractions for reuse. This model is based on the VVu-1.1200.4 high-frequency single-motor vibrating screen, with four working decks, each 1200 mm in diameter.
Technical data of the AVRK-4 vibrating screen are given in the table below.
| Nominal power of electric vibrators, kW | 2,2 |
| Number of decks | 4 |
| Deck diameter/area, m/m2 | 1,2 / 1,1 |
| Nominal frequency of body vibrations, Hz | 25 |
| Housing material (in contact with the screened material) | Stainless steel |
| Overall dimensions, mm, L x W x H | 1690х1350х1800 |
| Weight, kg | up to 680 |
The AVRK-4 round vibrating screen (vibrating apparatus) is designed for screening catalyst systems into target fractions for reuse, while simultaneously separating dust and catalyst crumbs. The device can be used to screen various substances (material classification), such as sand, bentonite clay, and others.
This vibrating screen operates on the following principle. An explosion-proof flanged vibrator motor with an unbalance shaft speed of 25 Hz, located in the longitudinal axis of the vibrating machine, below its center of gravity, generates short force pulses with a radial vector. These pulses ensure discrete movement of the screened material across the screen surface along an optimal spiral trajectory from the loading point to the unloading point of large particles (oversize product), while simultaneously passing fine particles (undersize product) through the screening surfaces.
Woven stainless steel wire mesh and perforated stainless steel plates are used as screening surfaces. Sets of meshes and perforated plates allow for the creation of several screening schemes for catalyst systems for various fractions. Depending on the material, meshes with different aperture sizes can be used. The mesh sizes of the main and additional meshes are specified in the delivery package.
The vibrating screen body is made of stainless steel, ensuring an extended service life. The screens are made of stainless steel wire or expanded metal sheet. The vibrating screens have an extended service life and are protected against clogging. The detachable joints of the AVRK-4 body components ensure a secure and leak-proof connection, while also allowing screen replacement with minimal downtime.
The vibrating screen is equipped with a flanged motor-vibrator made in Italy.
The AVRK-4 is mounted on a wheeled frame to facilitate movement between process stations. During operation, for safety and to prevent parasitic vibrations, the frame is secured with retractable screw supports.
The operation of the vibration apparatus is controlled using a mobile remote control in an explosion-proof design.
The AVRK-4 vibrating screen model quickly pays for itself thanks to its increased productivity and efficiency, as well as precise fractionation and reduced losses of useful product.
