Why use our Sifting Pans (AKA classifiers/sieves)? Classification is the most important step in gold recovery. Screen off large, worthless gravel and rock. Size your material to the proper dimensions of the gold you are expecting to recover. Our high quality stainless steel wire mesh is both accurate and durable for everyday use. The plastic is both lightweight and durable. Advantages of our stackable design: Resting the pans on top of each other takes up less space. The differently sized mesh screens make classifying even faster. Each pan fits perfectly on top of a 5-gallon bucket. Specifications: Top Diameter: 13-1/4" Bottom Diameter: 11" Mesh Size- 1/4”, Wire Thickness: 0.95 mm 304 Stainless Steel Wire Wire Thickness - 0.1 mm Fits on a 5 Gallon Bucket PP Plastic Material
