Screen assembly for vibratory separator

A screen assembly for a vibratory separator comprising

• supporting apparatus with a plurality of openings therethrough,
• screening material on the supporting apparatus over the plurality of openings,
• the supporting apparatus recovered from a predecessor screen assembly by applying heat to the predecessor screen assembly, the predecessor screen assembly having the supporting apparatus and predecessor screening material secured to the supporting apparatus by securing material, the heat applied to the predecessor screen assembly sufficient to degrade the securing material so that separation of the supporting apparatus from the screening material and recovery of the supporting apparatus is facilitated,
• the supporting apparatus from the group consisting of tubular frame, perforated plate, coarse wire mesh, and strip support,
• the screening material comprising a plurality of layers of screening material,
• the plurality of layers of screening material connected together by connection means,
• the connection means from the group consisting of epoxy, glue, and plastic, and
• the screening material connected to the supporting apparatus by material from the group consisting of epoxy, glue, and plastic.

A method for making a screen assembly for a vibratory separator, the method comprising

• recovering supporting apparatus from a predecessor screen assembly, the predecessor screen assembly comprising predecessor screening material on the supporting apparatus, said recovering done by a recovery method for recovering parts of the predecessor screen assembly, said recovery method comprising
• applying heat to the predecessor screen assembly, the screen assembly having the supporting apparatus and predecessor screening material secured to the supporting apparatus by securing material, the supporting apparatus having a plurality of openings therethrough,
• heating the securing material sufficiently to degrade the securing material to facilitate separation of the supporting apparatus from the securing material and recovery of the supporting apparatus, and
• connecting new screening material to the supporting apparatus.
