Keeping the Kilns Burning at Continental Brick
After two decades of service, Continental Brick began to have problems with their hammer mill crusher. As a solution, Innovative Processing Solutions specified a Stedman size reduction impact crusher and engineered a design to work the brick crusher into the existing system. The Stedman crusher easily handles Continental Brick’s 12” material and reduces lost production time.
Continental Brick (Martinsburg, West Virginia) has been successfully manufacturing face brick in the same location since 1917 using the same material from the Martinsville Shale Formation located within a mile of their plant. Their product line includes face brick used in residential and commercial applications primarily in the Northern Virginia, Pennsylvania, Chicago, New York, Washington D.C. and Baltimore areas. Through the years, they’ve upgraded equipment based on their capital equipment budget availability.
But as Don Sult, VP Operations at Continental states, “It has taken a lot of smart, hardworking people and their dedicated time and attention to make things…including some older workhorse equipment…operate efficiently.”
Grinding Operations Needed To Keep Up With the System
But a problem arose in early 2006… Their hammer mill crusher was starting to wear out after two decades of service. “It was just taking too much of our maintenance time and expense to keep our grinding operations running at needed productive levels (60 million standard brick equivalent/annually),” states Sult. He adds that this older equipment had numerous replacement parts to manage and there were no automatic systems on it (i.e. automatic opening, etc.). It took the company hours to do simple routine maintenance or repair because they had to unbolt the cover and remove it just to gain access to the working mechanisms. On average, their uptime availability was approximately 90% with their old hammer mill.
Continental Brick called Innovative Processing Solutions for turnkey answers. The first step was determining the best replacement equipment, the second, engineering the solution to make it fit into the existing system.
Step One: Find the Best Replacement Grinder
Material testing was conducted and Innovative engineers specified a Stedman Grand-Slam™ Model GS4860 Impactor to replace the existing hammer mill.
“We’re impressed with the ability of a single machine to handle our 12 inch material and give us the final output we need (-6 mesh) — and without needing to rework our system’s circuit design,” said Sult.
Step Two: Retrofit The Design to Work with Their Existing System’s Circuit
Retrofit engineering and installation of the Grand-SlamTM to the existing frame was a big challenge. Modifications were made, including a feed chute design to fit the new stand and crusher for proper material feed into the crusher’s inlet. With only five days to complete the installation before the shale inventory was depleted, Innovative personnel found cracks in the old frame. A new frame (10’ x 15’ by 10’ high) was quickly fabricated to replace it and production schedules were met.
“Innovative really kept their promises…and that’s critical to us. It would have cost us a lot of time and money to shut down these kilns,” added Sult. “They engineered a solution in about a day, delivered and installed the entire system in less than one week, saving us a four to six-week shutdown and more money in lost production than I care to think about!”
