the drum is connected to the drive 8 through a and degree of automation. Together with the
coupling, with which it rotates. Inside the drum, constantly improving foundry technologies,
on the bearing assemblies, a magnetic system which are being tested on its own experimental

drum 4 and the magnetic system 5. The angular a high-tech finished innovative product as

magnets in the sector 130-1500 attracts metal
magnetic particles to the surface of the rotating
drum. Partition 2 divides the lower part of the
body into two channels - B and C. In the lower
part, the scraper 3 separates the particles held
by the magnetic field on the drum and dumps
them into channel B, and the cleaned sand
passes through channel B.
The design of the support assemblies
prevents the drum wall from contacting the
magnetic system. The air gap S between them,
by reducing heat transfer, protects the magnetic
system from overheating when separating the
heated molding material and protects it from
demagnetization, which makes it possible to
magnetically separate the sand immediately
poured out of the mold at a high temperature
at the stage of the knockout operation.
Thus, the described equipment has a
number of new technical solutions at the level
of inventions, is multifunctional in terms of the
possibility of isolating dusty processes from the
working area of the workshop, mounting in a
continuous line even outside the workshop, and K.Kh. Berdyev, engineer, ch. constructor,
