I'm looking for detailed information regarding your magnetic separators. Specifically, I'm interested in understanding the different models you offer, along with their specifications, including processing capacity and efficiency rates. Additionally, please provide insights on the materials used in the construction, any available customization options, and pricing tiers for bulk orders. If you have any catalog or data sheet, that would be super helpful. Looking forward to your prompt response!
