Screen assembly for a vibratory separator

A method for installing a screen assembly of a vibratory separator, comprising:

• installing the screen assembly in a multi-screen configuration, wherein the screen assembly has a lower shaker screen, an upper shaker screen, a track, and an actuator disposed in the track, and comprising:
• inserting in the track the lower shaker screen at a lower level;
• inserting in the track above the lower shaker screen a small spacer having a first spacer dimension selected to correspond to the multi-screen configuration;
• inserting in the track above the small spacer the upper shaker screen at an upper level;
• and
• actuating the actuator disposed in the track to provide a clamping force to clamp the small spacer, lower shaker screen, and the upper shaker screen inserted in the track between an upper retainer and a lower retainer of the track in a clamped position of the multi-screen configuration.

A method for configuring a screen assembly on a vibratory separator between a multi-screen configuration and a single screen configuration, comprising:

• installing the screen assembly in a multi-screen configuration, wherein the screen assembly has a lower shaker screen, an upper shaker screen, a track, and an actuator disposed in the track, and comprising:
• inserting in the track the lower shaker screen at a lower level;
• inserting in the track above the lower shaker screen a small spacer having a first spacer dimension selected to correspond to the multi-screen configuration;
• inserting in the track above the small spacer the upper shaker screen at an upper level;
• and
• actuating the actuator disposed in the track to provide a clamping force to clamp the small spacer, lower shaker screen, and the upper shaker inserted in the track between an upper retainer and a lower retainer of the track in a clamped position of the multi-screen configuration;
• and
• installing the screen assembly in a single screen configuration, comprising:
• when the screen assembly is in the multi-screen configuration, removing the upper shaker screen and the small spacer from the track;
• after removing the upper shaker screen and the small spacer from the track, inserting in the track above the lower shaker screen and adjacent the actuator a large spacer having a second spacer dimension larger than the first spacer dimension of the small spacer and selected to correspond to the single screen configuration;
• and
• actuating the actuator to provide a clamping force to clamp the large spacer and the first shaker screen between the upper retainer and the lower retainer of the track in a clamped position of the single screen configuration.
