Feeding and pelletizing system for smelting antimony

Abstract

The invention discloses a feeding and pelletizing system for smelting antimony, which relates to the technical field of smelting. The system consists of an antimony concentrate hopper 1, an antimony concentrate screw feeder 2, a fine lime warehouse 3, a fine lime screw feeder 4, a burdening belt conveyer 5, a screw stirring conveyer 6, a blanking hopper 7, a disc type pelletizer 8 and a particle output hopper 10. The system has the characteristics of realizing fully mechanical operation, reducing the operation intensity of personnel, reducing raw material stock, lowering production cost and the like, is suitable for pelletizing antimony concentrate in the process of smelting antimony and can be used for pelletizing powder raw materials in other industries.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a feeding granulation system for antimony smelting. Background technique [0002] In the production process of the antimony smelting industry, since the powdered antimony concentrate cannot be directly put into the furnace, most of the antimony concentrate is made into spherical pellets and then put into the furnace. In the prior art, the process of making spherical material pellets usually adopts a honeycomb ball pressing system. The ball pressing system is all manually operated. During the ball making production, the antimony concentrate is manually shoveled into the ball making machine, and the balls are manually stacked and placed. Due to the fact that they are piled up in piles, the air permeability is poor, and the particle size is large and the drying speed is slow, it generally takes a week to dry thoroughly at room temperature; at the same time, because the ball forming...

AI Technical Summary

Problems solved by technology

In the prior art, the process of making spherical material pellets usually adopts a honeycomb ball pressing system. The ball pressing system is all manually operated. During the ball making production, the antimony concentrate is manually shoveled into the ball making machine, and the balls are manually stacked and placed. Due to the fact that they are piled up in piles, the air permeability is poor, and the particle size is large and the drying speed is slow, it generally takes a week to dry thoroughly at room temperature; at the same time, because the ball forming rate of the ball making machine is not high, it is only about 2 tons per hour, but The hourly processing capacity of the blast furnace is more than ten times that of it. Therefore, it is difficult to meet the production demand, and it is easy to cause the situation that the blast furnace and other materials are burned. Therefore, it is necessary to allocate a large amount of primary antimony lump ore, and there is a large backlog of working capital, which increases the market risk. ;In addition, since all production is done manually, the operation intensity of the employees is relatively high
