About the product

Components of the machine

The device consists of a housing that is designed for mounting all the components of the device. A vibration damper is installed inside the housing, on which an electromagnet is fixed. A vibrator table is attached to the top of the housing, vibrations from the electromagnet are transmitted through it to the table on which the sieves are installed. The sieves are attached to the table using a clamping device.

The principle of operation of the installation

The device is controlled from the panel, the controls include a toggle switch for turning the device on and off, a regulator for changing the amplitude of vibrations, a time relay for setting the duration of sieving. 50 grams of the suspension (sand base) remaining after the clay component is soaked, dried and placed on the upper grid of the set of sieves. A basin is installed under the lower sieve, the upper sieve is closed with a lid. The assembled set of sieves is installed on the machine table and fixed. The device is turned on by a toggle switch, turned off automatically. After sifting, the entire test sample is divided into twelve parts (eleven sieves and a basin). Each of the parts is weighed separately with an accuracy of 0.01 grams and multiplied by two. The obtained values are expressed as a percentage of the weight residues on each sieve in relation to the entire initial weight of 50g.
