Description

Anti-blocking type vibrating screen for ore mining

Technical Field

The invention relates to the technical field of ore mining, in particular to an anti-blocking type vibrating screen for ore mining.

Background

Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be exploited. Can be divided into metal mineral and nonmetal mineral. The unit content of useful components (elements or minerals) in the ore is called ore grade, the precious metal ore such as gold and platinum is expressed in grams/ton, and other ores are expressed in percentage. The ore is generally composed of ore minerals and gangue minerals. Ore minerals are metal or non-metal minerals that can be utilized in the ore, also known as valuable minerals. Such as chromite in chromium ores, chalcopyrite, bornite, chalcocite and malachite in copper ores, asbestos in asbestos ores, and the like. Gangue minerals are those minerals associated with ore minerals that are temporarily unusable, also referred to as unusable minerals. Such as olivine and pyroxene in chromium ore, quartz, sericite and chlorite in copper ore, dolomite and calcite in asbestos ore, etc. Gangue minerals are mainly non-metal minerals, but also include some metal minerals, such as copper ore containing a very small amount of galena and sphalerite, and are also called gangue minerals because of no comprehensive utilization value. The weight ratio of the ore mineral and the gangue mineral contained in the ore varies with different metal ores. The same ore may vary with the grade of the ore poor or rich. In many metal ores, the portion of gangue minerals tends to far exceed that of the ore minerals. Therefore, before smelting, the ore is subjected to ore dressing, and most of useless substances are discarded before smelting.

Can sieve the ore often in the ore mining process, just need a shale shaker to sieve the operation to the ore this moment, present shale shaker generally comprises for the metal mesh who offers the sieve mesh, the vibrations that drive the screen cloth through vibrating motor when sieving and then sieve the grit, but this kind of device is when using at present, because it adopts single screen cloth to sieve the ore, and the diameter of the sieve mesh of seting up on the screen cloth is fixed unchangeable, this diameter that has just led to unable change the sieve mesh sieves the ore of equidimension not and need to change the screen cloth and just can accomplish the ore of equidimension not, it is unchangeable to use to get up to exist a great deal of.

Simultaneously, the ore generally all relies on the screen cloth to sieve the ore at the screening in-process, and it can cause partial ore card often in the inside of sieve mesh when using, will cause the jam of screen cloth this moment, influences the screening of screen cloth, generally all clears up the problem that just can solve the screen cloth jam to the screen cloth after stopping the device among the prior art, and this kind of mode is comparatively wasted time and energy, can not satisfy the work demand when the ore screening, and work efficiency is lower.

Present ore screening plant is generally all to drop the inside completion collection of the collecting box of device bottom after accomplishing the screening, still need to shovel out the ore in the collecting box when using just can continue to use, can't accomplish the automatic discharging of ore to and the even ejection of compact of ore, increase the use procedure, use comparatively loaded down with trivial details.
