It consists of a seamless carbon or stainless-steel cone manufactured on a sheet metal lathe, a seamless SINT engineering polymer seal with integrated upper and lower flange, suspensions for connection with the silo and one or two electric vibrators. It is available with a range of seals, including an FDA-approved food-grade version and high-temperature version, and with a wide range of baffle plates.
