Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ore discharging, and in particular relates to a slag dressing and semi-autogenous grinding combined device. Background Art
[0002] In the mineral processing process, the feeding link of the semi-autogenous mill in the slag system has always used a suspended electric vibrating feeder. Although the suspended electric vibrating feeder has a simple structure and is cheap, it also has problems such as large spare parts consumption, high failure rate, and unstable feeding amount. Secondly, the height difference between the ore point under the flat belt and the ore receiving position of the belt is nearly 2m. During the production process, the slag blocks transported from the belt are very easy to damage the belt. The belt is in an inclined state, and the slag blocks are easy to roll down during transportation. During the rolling process, the belt scale frame is deformed by the impact, resulting in a short service life of the belt and frequent belt scale calibration. On the other hand, the existing semi-autogenous mill uses a grid-type cylindrical screen at the discharge end. Although the cylindrical screen is simple to maintain and has a low cost of use, since the cylindrical screen discharges materials through the synchronous rotation of the semi-autogenous mill, as the use time increases, the screen hole gap wears out and the screening efficiency decreases significantly, which has a great impact on subsequent production processes and equipment.

[0019] The slag from the slag pile 11 is fed into the coarse crusher 1 by the front loader 12 for coarse crushing. After passing through the coarse crusher 1, the slag enters the ore powder machine 2 for further crushing. The crushed ore is transported to the wet semi-autogenous mill 6 via the elevator 5 for grinding. The grinding product is screened by the linear vibrating screen 7 and the qualified particle size enters the next process.
[0020] The sitting vibrating feeder 3 is mainly connected to the bracket by making an installation bracket. The sitting vibrating feeder 3 and the bracket are connected through an intermediate spring. When the sitting vibrating feeder 3 is working, it mainly feeds by vibrating up and down. As the feeding stability is greatly enhanced, the flotation stability is also improved, and the comprehensive recovery of useful metals will also have a very positive effect. At the same time, the sitting vibrating feeder 3 is fixed in position after installation, and it will not loosen easily during use, and no adjustment is required. In addition, it is fixedly connected through the bracket, and there is no safety risk such as falling.
