Many different industries have a solid foundation rooted in aggregates. Recognizing the extensive use of these aggregates motivates us to continuously create and improve our rock crushing equipment to help you increase production, decrease maintenance and improve the overall efficiency of your operation. When it comes to quality and efficiency, our rock crushers are perfect for the job.
Primary crushers are first in a typical size reduction operation. Primaries like our Mega-Slam horizontal shaft impactor are commonly used in the aggregates industry to handle large feed sizes.The Grand-Slam HSI is well suited as secondary crusher for aggregate production for a wide range of materials including limestone, frac sand, gravel, stone, and more. Tertiary crushers are commonly used in the aggregates industry for final particle shaping to increase cubicity, and to produce a product size beyond what is capable from a primary or secondary. This stage of crushing is typically accomplished using a vertical shaft impactor or cage mill.
Specialty uses of limestone include the manufacturing of pharmaceuticals, toothpaste, paint, paper, caulking, and glass. Flooring materials, carpet, and plastics all contain finely ground recycled limestone. Common antacids are virtually 100% finely ground limestone. Farmers can reuse limestone to neutralize acidity in their soils, saving money by reducing fertilizer use while improving crop yields.
The 4-Row Cage Mill allows Aglime producers to meet most state Aglime specifications in open circuit. It will economically produce Aglime to any specification for both large and small producers. The 4-Row Cage Mill feed does not have to be dry. Clogging, jamming and plugging are eliminated. Available with capacities as low as 5 TPH up to 100 TPH, the 4-Row Cage Mill produces consistent product quality.
Stedman Machine and Innovative Processing Solutions, an affiliate of Stedman, worked with Duff Quarry Inc. to incorporate two large industrial crushers to handle the size of limestone crushed annually. Their previous machines required a great amount of maintenance, but with Stedman machines, Duff Quarry Inc. spends less time fixing and more time crushing. With the installed plant and crushers, the quarry can produce up to 1.5 million tons of limestone a year running at full capacity.
Theres no reason to guess what method will meet your needs.The Stedman Testing and Toll Processing Facility is the place to test your material in our full size equipment. If it can be crushed, ground, pulverized or mixed, chances are weve done it. We have more than 10,000 test reports to help get you to the best solution quickly.

Pegson was well-known for dependable lines of jaw crushers and cone crushers. The company was headquartered in the UK, but American distributors have helped to facilitate the provision of Pegson machines on this side of the Atlantic for decades.
Cedarapids is also owned by Terex, but this brand is still on the market. Cedarapids crushers are designed specifically to be modular machines, allowing them to be flexible in application and making setup efficient.

Allis Chalmers is another long-respected company that, today, has been dissolved into several different entities (none of which continue to provide rock crushers). However, as with Pegson rock crushers, there are still many Allis Chalmers rock crushers and parts available for resale.
Its widely held that the Symons brothers designed the first spring cone crusher in the late 1940s. Today, Symons isnt a brand as much as it is a type of crusher; the word is still used to denote machines that use this cone crusher technique. However, since it was the original brand, it merits an inclusion on this list.
Extec is another rock crushing brand thats still widely available for resale. Extec was based in the UK with a network of global distributors and was known for its leading design and manufacturing of mobile crushing machines.
If youd like more insight into any of these brands, get in touch with us. At Mellott Company, we have experience in servicing a broad range of rock crusher brands, including all of those listed here.
