Claim 0:
1. A magnetic density separator comprising:
a process channel through which in use magnetic process liquid and particles to be separated flow in a flow direction,
a magnetization device that is arranged to extend in the flow direction along at least one wall of the process channel so as to in use apply a magnetic field to the magnetic process liquid in a separation zone of the process channel to establish a cut density of the magnetic process liquid to separate the particles in the magnetic process liquid based on their density,
a laminator through which the magnetic process liquid is introduced into the process channel to flow laminarized in the flow direction along the separation zone, and
a feed channel through which a mixture of magnetic process liquid and particles to be separated is introduced into the process channel to join the laminarized magnetic process liquid;
wherein at least an end portion of the feed channel extends substantially parallel with at least an end portion of the laminator, such that the laminarized flow of magnetic process liquid introduced into the process channel by the laminator is introduced substantially parallel with the mixture introduced into the process channel by the feed channel; and
wherein the feed channel includes an entraining device that comprises a conveyor with entraining elements that is arranged to move along the flow direction and that extends at least through the feed channel; and the conveyor includes a first conveyor belt above the laminator and a second conveyor belt below the laminator, and the feed channel is defined between a top of the laminator and a bottom of the first conveyor belt and between a bottom of the laminator and a top of the second conveyor belt.
