摘要
A process for mixing at least two independent streams in a mixing device having independent inputs for each of the at least two independent streams, the process comprising the steps of: (i) feeding a first stream, provided as a free-flowing solids stream, to a pressure chamber; (ii) compressing the first stream in the pressure chamber; (iii) feeding the first stream to a first input in the mixing device; (iv) feeding a second stream to a second input in the mixing device; (v) impinging the first stream and the second stream on one another in a mixing device to produce a mixture; and (vi) dispensing the mixture from the mixing device; wherein the compressing in Step (ii) is conducted to achieve a substantially linear relationship between a weight of the first stream and a period of impingement of the weight in Step (v). A system for mixing at least two independent streams in a mixing device having independent inputs for each of the at least two independent streams, the system comprising: a mixing device having a first input and a second input, the first input capable of receiving a first stream and the second input capable of receiving a second stream, and impingement means for allowing the first stream and second stream to impinge on one another for a period to time; a compression chamber upstream of the mixing device, the compression chamber comprising: (i) an input for receiving the first stream as a free-flowing solids stream, (ii) compression means to compress the first stream to achieve a substantially linear relationship between a weight of the first stream and the period of time; and (iii) an output for allowing exit of the first stream from the compression chamber; connection means to connect the output of the compression chamber to the first input in the mixing device. Preferably, the process and system are adapted to produce a filled foamed isocyanate-based polymer (e.g. filled polyurethane foam). IMAGE
