PRINCIPLE WORKING |
| |
Working on the Gyratory Vibration with the help of eccentrically loaded motor, noiseless and maintenance free operation, mirror finish for S.S.contact parts. For easy flow of material, clamped easily replaceable screens. |
|
| The production capacity and H.P depends on the physical properties and particle size of the material and are subject to variation in all the above machines. |
|
| Note: Models for large scale, Small Scale, and Lab Size Vibro Sifter are also available. |
| SALIENT FEATURES: |
• Noiseless, Maintenance free & high speeds.
• Available in various models providing screening diameter of 12”, 20”, 30”, 36”, 48”, 72” etc
• Portable and compact.
• Electric power requirement less than other machine of the kind in the industries & lower energy consumption compared to reciprocating vibratory system.
• Standard machine are with TEFC motor explosion proof / flame proof motor material.
• SS 316 quality contact parts.
• Special requirement like brushing arrangements, SS lid with charging port and spring loaded outlets. • Easy dismantling and cleaning facility for contact parts.
• Wide range of screen sizes 4-300 Mesh.
• Double & Triple deck screens with outlet and hopper for bottom deck available on request. |

|
| OPERATION: |
| The top weight on the motor shaft rotates in a plane close to the centre of the mass of assembly. Rotation of the top eccentric weights creates vibration in the horizontal plane which causes material to move across the screen cloth to periphery increasing the horizontal throw, causing oversize material to discharge at a faster rate. The bottom eccentric weight rotates below the centre of mass creating tilt on the screen giving vibration in vertical and tangential plane. Increasing the vertical component of motion, this promotes turn over of material on the screen surface helping maximum quantity of undersize material to pass through the screen. Rugged Springs placed over the circular motor base amplifies the vibration. |
