Problems solved by technology

However, because the raw ore is unprocessed, the content of raw ore mud powder is high, which is easy to cause the vibrating screen to compact. When the screen of the vibrating screen is hardened, the vibrating screen cannot effectively screen out the mud powder in the raw ore, and the mud powder is not screened out. If the raw ore enters the blast furnace, it is easy to block the upper air flow of the blast furnace,

Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] It is worth noting that the orientation words such as "up" and "down" involved in this article are all determined relative to the perspective of the drawings, and are only for the convenience of description, and cannot be understood as limitations on the technical solution.

[0035] The screening process of the raw ore in the prior art is that the feeder transports the raw ore in the raw ore bin to the vibrating screen, and the screen of the vibrating screen screens out the fine-grained ore and mud powder in a vibrating state. The raw ore left on the screen is the qualified ore, and then the qualified ore enters the weighing hopper. When the weight in the weighing hopper reaches the set weight, the feeder and the vibrating screen stop immediately to achieve weighing. bucket accurate weighing. However, because the raw ore is unprocessed, the co...

Abstract

The invention relates to a method for reducing hardening of a raw ore vibrating screen. The method comprises the following steps: before production, firstly starting the vibrating screen, and then starting a feeder; conveying raw ore in a raw ore bin to the vibrating screen, vibrating out fine-fraction ore and mud powder through a screen mesh of the vibrating screen, and introducing qualified-fraction ore obtained after screening into a weighing hopper; when the weight of the qualified-fraction ore entering the weighing hopper reaches a weight set value, stopping the feeder, wherein at the moment, raw ore to be screened still exists on the vibrating screen, and the vibrating screen continues to vibrate until all the raw ore on the vibrating screen enters the weighing hopper; allowing the vibrating screen to perform empty vibration for a period of time to vibrate off marl bonded on the vibrating screen; and before feeding again, allowing the vibrating screen to perform empty vibration for a period of time, and then starting the feeder. After the weight of the weighing hopper reaches the set value, the stop time of the vibrating screen is delayed, and the problem of screen mesh hardening of the vibrating screen is solved through empty vibration of the vibrating screen.

Description

technical field [0001] The invention relates to the technical field of vibrating screens, more specifically, it relates to a method for reducing compaction of raw ore vibrating screens. Background technique [0002] Raw ore refers to unsmelted ore. Raw ore can be put directly into the furnace without processing, so the cost of ironmaking using raw ore is relatively low. Iron and steel companies generally use raw ore as one of the important methods to reduce costs and increase efficiency of blast furnaces. Raw ore is used in iron production, and the ratio of raw ore is used as an indicator of cost reduction and efficiency increase. At present, the raw ore screening process is that the feeder transports the raw ore in the raw ore bin to the vibrating screen, and the screen of the vibrating screen screens out the fine-grained ore and mud powder in the vibrating state, leaving the The raw ore on the screen is the qualified ore, and then the qualified ore enters the weighing ho...
