Halliday Sand & Gravel, Inc., of Houghton Lake, produces road gravel and asphalt material. The company also has three wash plants where stone and sand products are made for ready-mixed concrete.
"We have seven portable plants that move throughout Michigan in addition to the three stationary wash plants. We operate from Battle Creek to the Mackinac Bridge. We do not operate in Southeastern Michigan," Cliff Halliday Jr., vice president at Halliday Sand & Gravel, said.
The raw material is screened and crushed. Sometimes it is put back together and sometimes it is left split apart for the different products that the company wants to produce.
"Everything is tested and quality controlled. At one facility we are splitting out three different types of stone products for asphalt material, and one dense-graded product. Another facility is producing three coarse products, and we're splitting all of the sand out," Halliday said.
Halliday's equipment spread includes Lippman plants, Svedala cone crushers, a Hazmag impact crusher, an ISC vertical shaft impact crusher, and a Spokane vertical shaft impact crusher.
"Because we are a custom crusher, we need a lot of different types of machines. Every spread is different. Every time we move somewhere, we set up differently, depending on what the customer wants. We mix and match the machines according to the type of pit it is, the conditions, and what the customer is looking for," Halliday said.
"All of our spreads are custom made. We take plants that were built by companies like Lippman, take them apart and build them like we want them built." Halliday said that doing this provides more productivity.
He said that the company puts a high priority on quality. Halliday said that their testing operation is the key to high-quality aggregate products. "We feel that our big niche in the business is quality control."
