  • In this stage Yale is lifting and erecting the silos on the engineered foundations. One silo will be used to surge store the roofing granules for drive under truck loadout. The other is for calcium carbonate.
  • This shows the 14’ diameter, 80’ tall calcium carbonate silo being lifted into position next to its already erected 14’ diameter 50’ tall granules silo.
  • Granules silo which will mechanically be filled by a horizontal belt conveyors and an elevating bucket conveyor. The calcium carbonate silo will be filled via a vacuum type pneumatic blower system which utilizes pipes to convey the material to a filter receiver/separator on the silo roof.
  • This shows the expansiveness of the project nearing its completion.
  • This shows the heart of the vertically stacked separation system which features multiple vibratory screeners and air classifiers with the separated materials being pneumatically conveyed to the silos, a compactor and roll off boxes.
  • The unscreened material comes from its asphalt separation phase and is placed onto our 150’ long belt conveyor that brings the material either up a 80’ long inclined belt to the separation process or diverts it to be placed in roll off type trailers for other uses.
  • The dust and air are collected in a Cyclone to capture more product for reuse before going through a baghouse dust filter and fan.

Recovery Technology Solutions (RTS) received approval to build a state-of-the-art asphalt shingle recycling facility in Shakopee, MN. The plant extracts and separates asphalt and other materials from the shingles – including calcium carbonate, granite roofing granules, Fluff and sand – to be reused in different manufacturing processes.

Yale Mechanical’s Industrial Services division was selected to integrate and install the separation system for the new plant because of its experience in providing turnkey solutions for all equipment and resources required to complete a project of this magnitude in a very tight timeframe.

  • The new wheel lathe weighs approximately 60,000 lb.
  • Great care was taken when moving the extremely heavy piece of equipment.
  • Once the wheel lathe was unloaded, the team began the careful task of precisely aligning the new equipment.
  • BNSF operates one of the largest freight railroad networks in North America.

Yale Mechanical recently completed a major project at BNSF that involved the removal and replacement of a wheel lathe, which is used to true-up wheels on a locomotive. Our millwright team disassembled and removed the old equipment, then replaced the old foundation and support steel before finally unloading, setting and aligning the 60,000-lb piece of new equipment.

  • OSHA requires that fall protection be provided at elevations of four feet in general industry workplaces, five feet in shipyards, six feet in the construction industry and eight feet in longshoring operations.
  • The fall protection system installed by Yale features a rail and trolley system that allows workers to maintain an overhead tie off while they safely and efficiently access multiple elevated work areas.
  • Safety harnesses worn by workers are connected to secure anchor points on the overhead beams.

Kinder Morgan’s Dakota Bulk Terminal warehouse in St. Paul required a required a fall protection system to allow workers to safely access the top of storage silos along the Mississippi River. Yale Mechanical installed the fall protection system engineered to meet or exceed OSHA and ANSI Z359 standards. The structure includes a rail and trolley system to allow multiple workers to safely navigate work areas on top of silos.

  • Before: Yale Mechanical removed these 60-70 year old tripper belt conveyors.
  • Before: Yale Mechanical removed these 60-70 year old tripper belt conveyors.
  • After: We installed new enclosed drag conveyors at the top of the grain storage silos.
  • After: An elevator was used to get employees and equipment to the bin top level.

Yale Mechanical recently completed a project for General Mills which consisted of removing two tripper belt conveyors that were 60-70 years old and replacing them with enclosed drag conveyors at the top of grain storage silos. An elevator was used to safely get employees and equipment to the bin top level.
