ABSTRACT:
An explosive is produced in a continuous process made up of three stages. The first stage is mixing the solid ingredients of the explosive and transporting it to a mixing station. The second stage is emulsifying nitroglycerine and transporting it to the mixing station where the nitroglycerine is separated from the water and combined with other liquid ingredients. The third stage is the mixing stage where the solid and liquid ingredients are mixed or kneaded and formed into suitably-sized explosive units. The mixing station is provided with a mixer having a pair of hoppers in which are deposited the liquid ingredients and the solid ingredients, and which empty into a housing having a pair of rotating mixing screws which mix the liquid and solid ingredients. The liquid ingredients never contact the bearings of the mixing screws. The ratio of liquid to solid ingredients of the explosive may be varied by varying the feeding rate of each.
