The Uralelectromed subsidiary (The Manufacture of non-ferrous metals alloys) has produced a cone-sieve for the copper sulfate shop.
Previously the sieve was ordered in Germany and had a thickness of 1 mm.
The subsidiary increased the wall thickness to 3 mm, and the sieve proved to be much cheaper in production.
At present the cone-sieve is being tested in the copper sulfate shop. (Ukrainian metal)
