Sand Preparator

STATES SAND PREPARATOR.The States Sand Preparator combines a 75 cu. ft. sand receiving hopper, a 2’ x 5’ deck screen, and an 18” feeder belt into one compact package. The unit is specifically designed to clean the return shakeout sand of foreign materials such as core butts and tramp metal. An optional, magnetic head pulley may be added to remove other foreign, ferrous, magnetic material.

The Sand Preparator Unit is designed to allow for easy loading with most conventional front-end loaders. Return material is then fed from the hopper to the vibrating screen. Foreign particles are removed, and the screened sand is loaded onto the feeder belt. The unit will process up to 25 tons per hour of normal return foundry sand. The Sand Preparator is designed to load the M-1000 and M-1500 Ringmullors, plus other mulling equipment.

The Sand Preparator is rugged built, constructed from ¼” plate and structural steel members to meet the strictest needs of the foundry industry. Special epoxy paint on the ¼” plate receiving hopper prevents sand from sticking to the inside hopper surfaces. The 2’ x 5’ vibrating screen unit consists of two heavy- duty bearings and shaft with counter weights to accomplish the screen motion. The screen is belt driven with a TEFC motor.

The vibrating screen loads clean sand into the 18” conveyor belt which is equipped with a heavy duty shaft mounted drive and TEFC motor.

The Sand Preparator unit is complete with necessary OSHA approved safety guards to protect personnel. All starters and controls are included with the unit.

Optional, new sand and bond vibratory feeders are available as part of the unit if required. These units consist of 3 cu. ft. storage hoppers with adjustable flow rate vibratory pan feeders to meter the correct amounts of bond needed for the sand.

Preparator is designed to load States Ringmullor Models M-1000 and M-1500, plus most other types of mullers.
