Levels of potentially toxic Pb, Al, Cd, and Hg were very low as were levels of V, B, Fe, Zn, P, Mg, N, F, Se, Cu, and Cr. 40. The third pulverization was performed under the following conditions: (1) air speed - 10,000 rpm; (2) feeding time - 10 seconds; (3) cycling time - 20 seconds; (4) discharging time - 10 seconds; (5) feed rate - 1 kg/time; (6) baghouse - 60%; and (7) temperature - room temperature. 22. (4) the mixture of step 3 was introduced into an injection molding machine (Amco) at 250 °C to form a nylon 66 composite plaque comprising 30% eggshell powder. In this instance, the initial pulverization was performed at the following conditions: (1) air speed - 3,500 rpm; (2) feeding time - 10 seconds; (3) cycling time - 0 seconds; (4) discharging time - 10 seconds; (5) feed rate - 8 kg/time; and (6) temperature - room temperature. A2. isolating the eggshell component from the bulk pulverized material. The determination of air speed will largely be dependent on the type of apparatus used, but regardless, should be sufficient to cause separation of the eggshell component from the inner membrane component. There are about 27 trace elements found in eggshell. [0006] Additionally, an eggshell powder composition is provided. 35. At this point, the collected eggshell component can either be applied to a second screen comprising a mesh size smaller than that of the first screen or re-exposed to the air flow at the same or an increased speed to further pulverize the material and then applied to the second screen. The product of any of claims 15-27 wherein the eggshell powder is hydrophobic. [0032] The eggshell component from the second pulverization run included some larger particle sizes so the pulverization was repeated for a third time. The drop possesses a water contact angle indicative of a hydrophobic material. [0021] The second component comprises a polymer. [0029] The following examples describe specific eggshell powder compositions and a process of producing such as well as polymer composite compositions formed using the processes described herein. The composition of claim 73 wherein the eggshell component is about 30% by weight of the total weight of the composition, wherein the nylon 66 is about 69.5% by weight of the total weight of the composition, and wherein the mineral oil is about 0.5% by weight of the total weight of the composition. Chicken eggshell powder contains lots of calcium. There is widely varying information on the nutrient composition of … The subsequent pulverizing steps can be performed under the same conditions as the initial step or with higher air speeds for the same or longer time periods. Interestingly, CaCO 3 is one of the four primary raw materials that produce cement. For example, the first component comprises eggshell powder that is substantially free of eggshell inner membrane and retains the original lipid-protein surface structure of the eggshell from which the powder was derived. The utilization of eggshell powder in cement also helps to reduce the carbon dioxide emissions from cement factories by reducing clinker production. Extrusion was performed by a twin screw extruder (Amco) for composites 1-4 and single screw extruder for composites 5-6. Specifically, the composite of nylon 66 and eggshell powder presents higher flexural modulus (3270 Mpa) than nylon 66 itself (2920 Mpa). [0035] The plaque comprising nylon 66 and 30% eggshell powder was then tested for flexural modulus, tensile strength, and heat deflection at 0.4S MPa and 1.8 MPa. A process for producing an eggshell powder comprising the steps of: exposing a quantity of eggshell to air flow at a speed sufficient to pulverize the eggshell thereby rendering a bulk pulverized material comprising an eggshell component and a separated inner membrane component; applying the bulk pulverized material to a first screen comprising a mesh size sufficient to retain the separated inner membrane component on the surface of the first screen while permitting passage of the eggshell component through the first screen; and collecting the eggshell component following passage through the first screen, wherein the eggshell component collected forms the eggshell powder of a first particle size, wherein the first particle size is less than or equal to that permitted to pass through the first screen. Furthermore, the composite of nylon 66 and eggshell powder exhibits higher heat deflection temperature at 1.80 MPa (78.3 °C) than nylon 66 (74 °C). 32. 19. The particle size of the eggshell powder can be any size desired and most effective for the particular polymer used in the composite. The composition of any of claims 65-67 wherein the eggshell component is about 30% by weight of lite total weight of the composition. This resulted in the production of a bulk pulverized material consisting of an eggshell component and an inner membrane component. 84. The composition of any of claims 43-51 wherein the eggshell powder has a total ash content from about 90% to about 95%. The composition of claim 43 wherein the eggshell powder has a fat content of about 0.35%.
