Abstract
Disclosed herein are systems and methods for processing waste egg shells into (i) a first product comprising calcified egg shell particles having diameters of 3μ or less, and (ii) a second product comprising calcified egg shell particles having diameters in a range from about 3μ to about 7μ. The first product may be used as a CaCO3 substitute for paint compositions and plastics compositions. The second product may be used as a CaCO3 blasting media substitute for use with abrasive blasting equipment.
Claims11
A method for producing a first product and a second product from waste egg shells, comprising the steps of:
- separating an inner membrane component from a calcified outer shell component of the waste egg shells to produce therefrom an inner membrane fraction and a de-membranized calcified component;
- washing the de-membranized calcified component;
- washing the de-membranized egg shell calcified components to remove any remaining membrane components, then drying the washed de-membranized egg shell calcified components.
- milling the dried de-membranized egg shell calcified components to produce small-diameter particles therefrom.
- separating the milled small-diameter egg shell calcified particles into three fractions wherein the first fraction comprises calcified particles having diameters of 3μ or less, the second fraction comprises calcified particles having diameters in a range from about 3μ to about 7μ, and the third fraction comprises calcified particles having diameters greater than 7μ.
- re-milling the third fraction and then separating additional quantities of the first fraction the second fraction, and if necessary, the third fraction.
- repeating the re-milling step as many times as necessary to eliminate egg shell calcified particles having diameters greater than 7μ.
- separately collecting the first fraction as a first product and the second fraction as a second product.
A system for processing waste egg shells into (i) a first product comprising calcified egg shell particles having diameters of 3μ or less, and (ii) a second product comprising calcified egg shell particles having diameters in a range from about 3μ to about 7μ, said system comprising:
- equipment for separating an inner membrane component from an outer calcified shell component of the waste egg shells thereby producing a de-membranized calcified shell component, said equipment in communication with;
- equipment for washing the de-membranized calcified shell component, said equipment in communication with;
- equipment for drying the washed de-membranized calcified shell component, said equipment in communication with;
- milling equipment, said equipment in communication with;
- powder separation equipment;
- and
- at least two sets of packaging equipment for packaging two product streams, said packaging equipment in communication with the powder separation equipment.
