SMK balanced wear-resistant double-core adjustable shrinkage hole is a mature product developed and improved by our company on the basis of single-core adjustable shrinkage hole.
Adjustment principle:
The symmetrical double-core gate of the shrinkage hole adjusts the opening area by reciprocating movement outward from the center of the pipe at the same time, so the high-speed wind-powder mixing airflow in the pipe can always keep flowing in the center of the pipe. This fundamentally eliminates the abrasion of the pipe wall and reduces the flow resistance, thus prolonging the service life of the pipe.
Technical parameters:
Minimum cross-section area of circulation: 25
Maximum flow area: 100%
Gate material: ZG35CrMnSiMoRe
Connection: welding or flange connection
Manufacturing standard: Q/321282HZC05-2010
