Independent Claim
213 words
Device for continuously mixing at least two materials, at least one of which can be pumped, comprising a feed pump, a supply pipe to said feed pump through which fresh material to be mixed flows, a mixing tank in which a circulatory movement of material is produced by said feed pump, a central feed pipe connecting said feed pump with said mixing tank, at least part of the fresh material supplied to the mixing tank being conveyed by said pump into said mixing tank by way of said central feed pipe, the open end of said central feed pipe being constructed in the form of a pressure nozzle with a restricted outlet, said pressure nozzle being located slightly above the bottom of said mixing tank, said bottom of said mixing tank effecting a uniform deviation of a jet of material issuing from said nozzle, a device for varying the quantity of material flowing into said mixing device, a connection pipe between said supply pipe to said feed pump and said mixing tank, and a throttle valve in said connection pipe, whereby fresh material can be introduced into said mixing tank through said throttle valve and connection pipe, and material can be withdrawn from said mixing tank through said connection pipe and throttle valve.

Device for continuously mixing at least two materials, at least one of which can be pumped, comprising a feed pump, a supply pipe to said feed pump through which fresh material to be mixed flows, a mixing tank in which a circulatory movement of material is produced by said feed pump, a central feed pipe connecting said feed pump with said mixing tank, at least part of the fresh material supplied to the mixing tank being conveyed by said pump into said mixing tank by way of said central feed pipe, the open end of said central feed pipe being constructed in the form of a pressure nozzle with a restricted outlet, said pressure nozzle being located slightly above the bottom of said mixing tank, said bottom of said mixing tank effecting a uniform deviation of a jet of material issuing from said nozzle, a device for varying the quantity of material flowing into said mixing device, a connection pipe between said supply pipe to said feed pump and said mixing tank, and a throttle valve in said connection pipe, whereby fresh material can be introduced into said mixing tank through said throttle valve and connection pipe, and material can be withdrawn from said mixing tank through said connection pipe and throttle valve.
Claim 3
Dependent Claim
109 words
Method of operating a mixing device comprising maintaining the output of a pump pumping material into said mixing device at least approximately constant and varying the amount of fresh material supplied to said mixing device, whereby when said amount of fresh material exceeds the capacity of said pump, a part of the fresh material bypasses the pump by means of a connection pipe and passes directly into said mixing tank, and when the capacity of the pump exceeds the amount of fresh material, the deficit in material is taken from said mixing tank through the connection pipe and passed together with the fresh material back into said mixing tank.
Claim 4
Dependent Claim
109 words
Method of operating a mixing device comprising maintaining the output of a pump pumping material into said mixing device at least approximately constant and varying the amount of fresh material supplied to said mixing device, whereby when said amount of fresh material exceeds the capacity of said pump, a part of the fresh material bypasses the pump by means of a connection pipe and passes directly into said mixing tank, and when the capacity of the pump exceeds the amount of fresh material, the deficit in material is taken from said mixing tank through the connection pipe and passed together with the fresh material back into said mixing tank.
