SAND RECLAMATION

For Reclaimed Sand That Performs As Well As – Or Better Than – New

Sand is the largest foundry process waste, typically constituting about 70% of total waste volume. Environmentally it is becoming increasingly more difficult to dispose of these great quantities of waste sand into a landfill. But waste is not the only challenge related to spent foundry sand. Replacing that sand with an adequate amount of new sand in order to maintain consistent properties can become quite costly.

Imagine if you were able to….

  • Reduce your total sand cost, which includes the following: purchase cost, delivery cost, unloading cost, storing cost, handling cost and disposal costs including expensive landfill fees
  • Be more environmentally responsible by reducing materials sent to a landfill
  • Produce better castings at a lower cost

Fortunately, most foundry sands are reclaimable and can be effectively reused. In today’s competitive market you can’t afford to miss the savings and technical advantages available from reclamation.

Simpson Technologies introduced the concept of sand reclamation in the 1950s. Over 500 foundries around the world have relied on the Pro-Claim to cost effectively reclaim their sand.

Choosing the optimal size reclaimer is easy. Before making a purchase decision, the Simpson Performance Laboratory will test your foundry’s sand and select the optimum reclaimer for your sand system requirements. Implementation is simple, no operator is required and maintenance is low because there are no moving parts.

HOW IT WORKS

STEP 1 – The sand inlet permits direct connection to a gravity feed from your sand bin, providing simple, continuous operation.

STEP 2 – The turbine type blower introduces air into a common plenum, providing even air dispersion among the cells. The air accelerates through a nozzle at the bottom of each blast tube to the optimum air/sand mixture for your application.

STEP 3 – Propelled by air, sand is accelerated at a controlled rate up through a blast tube to a conical target. The Pro-Claim sand reclaimer tubes typically require minimal maintenance, but when maintenance is required, the design makes tube removal easily accomplished through an outside door.

STEP 4 – Sand accelerated through the blast tubes is scrubbed against sand and trapped under the conical target. Since scrubbing is accomplished by sand-to sand contact, maintenance and replacement of wear parts are greatly reduced.

STEP 5 – As the sand curtain falls from the target area it is exposed to exhaust air drawn through a shroud surrounding the target. Residual binder and excess fines scrubbed off the sand grains are removed to dust collection. This controls Loss on Ignition and maintains the original sand screen distribution.

STEP 6 – Throughput through the Pro-Claim is controlled by a series of adjustable deflector plates between the cells. A controlled amount of the sand is recirculated into the same cell and the remainder is diverted to the next cell. If needed, for more intensive scrubbing the sand can be retained in each cell longer. This controls the degree of cleanliness of the reclaimed sand without needing to recycle the sand through the entire unit. The reclamation process is repeated through as many successive cells as needed, depending on your specific application.

STEP 7 – When the sand emerges from the last cell, excess fines are removed in a final dedusting chute. A vibratory classification screen separates and discharges refuse through a horizontal opening, and reclaimed sand enters a discharge hopper below.

Simpson Performance Laboratory Test Program

“Testing prior to installing purchasing the machine was extensive. When we finally installed… it was amazing that we used the same settings that they did in the lab.” 
-Butch Pacula, Foundry Manager, MBAF

No two foundries are exactly the same in their combination of sand, binder and operating conditions. As a result, the only way to properly determine the performance and expected payback of reclamation is to conduct a test using your foundry’s sand prior to buying a system.

Click on the video to watch an actual test conducted in the Performance Lab. Then, hear how the settings from the test compared to the settings and performance after installation.

CUSTOMER TESTIMONIAL

“The overall reason we wanted to do this is basically to keep the sand that we purchase within the building, minimize if at all possible anything that we throw away and give us the quality for our customers. From an environmental standpoint our carbon footprint needed to be better.” – Foundry Manager
