A method of manufacturing a large stationary, aggregate processing screening tower by fabricating weldment modules and preassembling them with aggregate processing equipment internal within the weldment modules, transporting the preassembled weldment modules to a field work site where the tower is to be erected on a foundation, aligning the modules and stacking the modules in layers and then bolting adjacent modules together. A large stationary, aggregate processing screening tower has weldment modules preassembled with aggregate processing equipment internal within the modules. The preassembled modules are stacked up on one another and secured together and can receive aggregate product at the top module and the product is processed by screening and sizing as it moves downwardly by gravity through the modules and their processing equipment for final clarification and collection of the product.
A double screen vibrator having two stationary vertical side walls having upper and lower screens positioned one above the other and mounted between said side walls and positioned at a downwardly inclined angle, said vibrator having a lower discharge end having outlet conduits for discharging a screened product from each of said screens, high frequency electric vibrators connected with said screens for vibrating said screens at a frequency of 3000 to 5000 rpm,
A double screen vibrator, capable of receiving aggregate, said aggregate comprising sand and a minus 200-mesh material, having two stationary vertical side walls with upper and lower screens positioned one above the other and mounted between said side walls and positioned at a downwardly inclined angle, said vibrator having a lower discharge end having outlet conduits for discharging a screened product from each of said screens, high frequency electric vibrators connected with said screens for vibrating said screens at a frequency of 3000 to 5000 rpm,
