Adjustable spring grizzly bar material separator

An adjustable spring grizzly bar material separator comprising:

• a plurality of flexible tines;
• a cassette, wherein the plurality of flexible tines are each coupled on an end to the cassette;
• and
• a first set of spacers removably coupled within the cassette between the plurality of tines, wherein the first set of spacers separate the plurality of flexible tines a first predetermined distance to set the size of material that is to be separated from an amount of aggregate flowing over the tines.

A method of using an adjustable spring grizzly bar material separator, the method comprising:

• coupling the adjustable spring grizzly bar material separator adjacent a vibratory plate feeder, the adjustable spring grizzly bar material separator comprising a plurality of flexible tines;
• depositing material on the vibratory plate feeder and the adjustable spring grizzly bar material separator;
• flowing material from the vibratory plate feeder to the adjustable spring grizzly bar material separator;
• separating material fines from larger rocks in response to the fines flowing through spaces between the plurality of flexible tines of the adjustable spring grizzly bar material separator;
• flexing at least one of the plurality of the flexible tines in response to forces of larger rock being applied to the flexible tines by force of the material flowing over the flexible tines;
• adjusting space sizes between the plurality of flexible tines;
• supporting an end of the flexible tines prior to adjusting the spaces between the plurality of flexible tines;
• and
• adjusting the space sizes further comprises replacing a first set of spacers with a second set of spacers, wherein the second set of spacers separates the plurality of flexible tines a second predetermined distance, the second predetermined distance being different from a first predetermined distance associated with the first set of spacers.
