The invention belongs to the technical field of pulp feeding, in particular to an electric pulp reversing feeding device arranged between a semi-autogenous mill and a vibrating screen. Including semi-autogenous mill discharge hopper, A vibrating screen feeding funnel and B vibrating screen feeding funnel and electric control device, there is a walking track on the semi-autogenous mill installation platform, and this walking track is rolling with a walking feeding trolley Connection, the walking feeding trolley is connected with an electric drive device, which is set on the installation platform of the semi-autogenous mill and connected with the electric control device. The walking feeding trolley consists of a trolley box, a set of walking rollers and Composed of split plates, the bottom plate of the trolley box is respectively provided with a pulp A passage port and a pulp B passage port. The electric drive device is composed of an electric push rod and a push rod support. The invention has reasonable configuration, compact structure and convenient operation. The operation is stable and reliable, the production rate is high, the production cost is reduced, and the production can be effectively guaranteed.
Description
technical field [0001] The invention belongs to the technical field of pulp feeding, in particular to an electric pulp reversing feeding device arranged between a semi-autogenous mill and a vibrating screen. Background technique [0002] With the development of large-scale iron ore concentrators, ore semi-autogenous grinding, autogenous grinding technology has been widely used. The ore discharge products of the self-grinding and semi-autogenous mills need to enter the vibrating screen for classification, and the classified coarse-grained and fine-grained products are then respectively entered into different subsequent operations. The vibrating screen needs to be replaced regularly due to the wear of the material on the screen to ensure that the production will not be affected. For this reason, generally a mill is equipped with two sieves, one of which is working and the other is standby. In the previous arrangement, the ore discharge of the mill directly enters one of the ...
