A process for recovering a product from a carpet comprising a low ash fiber product, the process comprising: a) supplying the carpet from a source to a separator comprising a body, the body extending along a body axis and including one or more walls, the body being substantially hollow such that the one or more walls define a chamber that is sized to receive the carpet from the source, the body having an inlet opening that is located substantially underneath the source such that the carpet falls from the source through the inlet opening; b) applying mechanical force within the chamber to the carpet to break a bond between an adhesive and a face fiber material of the carpet, the separator comprising an impact device for separating the material, the impact device positioned within the chamber of the body such that the impact device contacts the carpet when the carpet is located within the chamber, the impact device comprising: a shaft coupled to a motor that causes the shaft to rotate; and end effects that contact the carpet when the shaft is rotated; c) controlling a flow of the carpet through the chamber such that with each turn of the shaft, the carpet falls downfield from a previous position and the end effects move the carpet downfield; d) separating within the chamber the face fiber material from the adhesive using a centrifugal screening device such that a first co-product of the carpet passes through the centrifugal screening device while passing from the chamber and through a first outlet, and a second co-product of the carpet passes from the chamber and through a second outlet, wherein the inlet opening is positioned along a top of the body and wherein the first outlet and the second outlet are located at different axial locations along a length of the body and positioned along a bottom of the body; and e) recovering, from the carpet, the low ash fiber product. a) supplying the carpet from a source to a separator comprising a body, the body extending along a body axis and including one or more walls, the body being substantially hollow such that the one or more walls define a chamber that is sized to receive the carpet from the source, the body having an inlet opening that is located substantially underneath the source such that the carpet falls from the source through the inlet opening; b) applying mechanical force within the chamber to the carpet to break a bond between an adhesive and a face fiber material of the carpet, the separator comprising an impact device for separating the material, the impact device positioned within the chamber of the body such that the impact device contacts the carpet when the carpet is located within the chamber, the impact device comprising: a shaft coupled to a motor that causes the shaft to rotate; and end effects that contact the carpet when the shaft is rotated; a shaft coupled to a motor that causes the shaft to rotate; and end effects that contact the carpet when the shaft is rotated; c) controlling a flow of the carpet through the chamber such that with each turn of the shaft, the carpet falls downfield from a previous position and the end effects move the carpet downfield; d) separating within the chamber the face fiber material from the adhesive using a centrifugal screening device such that a first co-product of the carpet passes through the centrifugal screening device while passing from the chamber and through a first outlet, and a second co-product of the carpet passes from the chamber and through a second outlet, wherein the inlet opening is positioned along a top of the body and wherein the first outlet and the second outlet are located at different axial locations along a length of the body and positioned along a bottom of the body; and e) recovering, from the carpet, the low ash fiber product.
