Pan Materials and Finishes

A food industry standard, stainless steel is Key’s primary material for Smart Shaker® Vibratory Conveyors. Type 304 is a strong, corrosion-resistant iron-based alloy with 18 to 20 percent chromium, 8 to 12 percent nickel, and traces of carbon and silicon. More resistant to certain corrosive media, Type 316 has 2 percent less chromium, 2 percent more nickel, and 2 percent molybdenum added. Both Type 304 and Type 316 stainless steel are available in smooth or textured surfaces, or wire mesh. Key Technology offers four product-zone finishes for Key vibratory conveyors, to ensure that your Smart Shaker® vibratory conveyor  is perfectly suited to your processing, food safety and regulatory needs.
