Basalt Multi-Cyclones MBK

Due to their simple design, cyclones are among the most popular devices for removing solid particles from gas streams. However, cast iron cyclones often face problems such as high resistance to gas flow and limited service life, especially when purifying gas containing abrasive particles.

Multi-cyclone gas cleaning systems have become widely used due to their ability to clean large volumes of gas. A single multi-cyclone unit contains several cyclone elements operating simultaneously. The production of multi-cyclone elements from cast stone is an effective way to increase their service life. The parallel operation of the multi-cyclone elements addresses the issue of gas cleaning performance, where choosing a multi-cyclone with the required number of elements ensures the necessary throughput. Using smaller cyclones in the assembly increases the efficiency of dust removal from the air by one and a half times compared to a single cyclone of similar diameter. Additionally, the optimal use of cast basalt contributes to effective gas cleaning from large abrasive particles.

Block-combined type multi-cyclones (MBK) have found their application in cleaning systems at sintering plants of ferrous and non-ferrous metallurgy for removing dust from gases generated during the sintering process. Long-term stable operation and high gas cleaning efficiency are achieved due to the low wear of the cast stone elements, whose hardness is four times that of cast iron. The smooth surface of cast basalt (roughness of 0.04 mm, which is 3-4 times less than that of cast iron) significantly improves dust removal from the cyclone walls, thereby increasing its efficiency.

One of the advantages of cast stone cyclones is the absence of electrostatic charge, which prevents the adhesion of particles with magnetic properties, unlike cast iron products. The narrowing of the passage section in a cast stone cyclone increases the gas flow speed to 5-6 m/s, contributing to higher gas cleaning efficiency.
