Vibration Machine - Single-phase Ac Supply, 230 V, 50 Hz | Precision Programmable Vibration For Effective Mortar Cube Preparation

Concrete moulds are easily cast by using a tamping bar or a vibrating table. However air trapped in cement mortar paste can not be thus removed while casting cement mortar moulds. Easy method is to impart greater vibrating of lesser amplitude to the mould while casting This is achieved in a vibrating machine.

Vibrating machine is used for the preparing of mortar cubes for the determination of compression strength of ordinary and rapid hardened Portland cement, low heat Portland cement, Portland blast furnace cement and high alumina cements.

A specially designed Vibration Machine is used for vibrating the mix in moulds according to strictly controlled programmer at a frequency of 12,000 A 400 cycles per minute. The Vibrator is mounted over coiled springs and the vibrations are developed by means of a revolving eccentric shaft. The center of gravity of the vibrator, including the cube and mould, is either at the center of the eccentric shaft or within 25 mm below it. The simple design of the machine facilitates easy assembly and dismantling of the cube moulds. The machine is suitable for operation on 230 V, 50 Hz, and single-phase, AC supply. Each machine is supplied with one cube mould.
