An improved mixer for cementitious materials is described. This mixer is mobile and carried to the desired site and comprises a series of tanks and bins for containing the material to be mixed. The device is particularly useful in mixing hazardous wastes (e.g. low level radioactive soils, for example) within cementitious material along with sealants and chemicals designed to encapsulate the hazardous wastes therein. In order to thoroughly mix, and thus contain the hazardous wastes, the residence time within the mixing means must be between 4 and 45 seconds. This residence time may be achieved by keeping the mixing means within certain parameters of angles, relative to the ground, speed of mixing and length of mixing. By carefully controlling these variables, it is possible not only to achieve thorough mixing and encapsulation of the hazardous waste and to make a mobile mixing device that is extremely useful within the metes and bounds of the invention.
A mobile mixing device for the preparation of cementitious materials to contain and encapsulate hazardous wastes comprising a mobile element having at least three containers, two of said containers being located over a transporting means, and said transporting means being connected to a mixing means, the first of said containers having an aqueous mixture of chemical sealants, a second of said containers having hazardous waste and a third of said containers having cementitious material therein, said first and said second containers being located over said transporting means, wherein when said hazardous waste and said cementitious material are placed on said transporting means and transported to said mixing means, and said aqueous mixture of chemical sealant are added thereto, said mixture of hazardous waste, cementitious material and said chemical sealant are caused to be held within said mixing device for a residence time of between 5 and 45 seconds prior to exit therefrom.
A mobile mixing device for the preparation of cementitious materials to contain and encapsulate hazardous wastes comprising a mobile element mounted on a trailer designed to be towed by a tractor, said mobile element comprising in order;
