A Single Breakdown Can Cripple Your Pit

Running a sand and gravel operation isn’t just about moving stone—it’s about keeping everything flowing. For Tim, one of the biggest challenges was equipment reliability. Even a single pump or part failure could halt production, delaying deliveries and putting pressure on both his team and his customers.

Every delay is costly. Maintaining multiple products—fill sand, 6A stone, rip rap, and more—meant there was no room for downtime. Tim needed a system he could trust to run consistently, so he could focus on quality, keep his customers happy, and ensure the business kept moving forward without unnecessary interruptions.

Finding the Right Screen Changed Everything

Tim knew he needed a system that could handle multiple sand and stone products efficiently without slowing down production. After researching his options, he came across MHK Equipment and Services that showed him the Rubble Master MSC8500M screening plant. From the moment he saw it in action, he was impressed by the ease of operation and thoughtful design:

• Quick screen changes and maintenance — the catwalk and layout made it easy to access all parts of the plant safely
• Consistent, reliable output — every product, from fine fill sand to rip rap, came out clean and spec-ready
• Remote operation — simple controls meant Tim could manage the plant from the loader cab, keeping production moving smoothly
• Responsive support — whenever questions or issues arose, he could count on the team to provide answers or parts immediately

For Tim, this wasn’t just about a machine—it was about restoring confidence and efficiency to the pit. He could now focus on running a productive, high-quality operation rather than constantly putting out fires.

The Range of Products That Keep Customers Coming Back

With the right screening system in place, Tim is able to consistently produce a wide range of sand and stone products, each tailored for a specific purpose. The key is precise screening, consistent flow, and careful handling of each material.

Here’s what comes out of the pit:

• Fill Sand — fine, clean sand used for bedding, leveling, and general construction projects.
• Quarter Sand — slightly coarser than mason sand, perfect for ice control on roads during Michigan winters.
• Bird’s Eye Sand (¼ inch minus) — ideal for packing pipe and drainage applications.
• 3/8” P Stone — commonly used around basements and drainage areas to ensure proper water flow.
• 6A Stone — versatile aggregate for Portland mixes, drain fields, and road base.
• 1–2” Stone — durable material for roof stone, drainage projects, and heavier construction applications.Rip Rap — large stone for embankment protection, erosion control, and shoreline stabilization.
