Nonclogging Water Spray System for Continuous-mining Machines: Installation and Operating Guidelines.
NTIS: PB 265 934 :10 pages
A new nonclogging water spray system for continuous-mining machines has been developed under contract with the Bureau of Mines. This paper presents installation and operating guidelines for the system, which consists of improved and easily maintained machine-mounted hardware, including an inline y-strainer, a hydrocyclone, a backup filter, and two quick-opening valves for flushing particulates from the strainer and hydrocyclone. Underground tests with continuous- mining machines have shown that when properly installed and maintained, the new system virtually eliminates nozzle clogging and thus greatly reduces spray maintenance. The system is relatively inexpensive and has been installed on typical continuous-mining machines for a total cost under $1,000.
