Description

A kind of pneumatic cleaner
Technical field
The utility model is related to a kind of preparation equipment, specially a kind of pneumatic cleaner, especially suitable for the sorting of mica, Belong to mine mechanism technical field.
Background technology
Pneumatic separation is under the jurisdiction of gravity ore dressing method.For a long time, gravity separation is mostly using wet method gravity treatment (using water as medium) Based on, not only type is more for wet method gravitational separation equipment, adaptable, and performance is also become better and better.But meanwhile dry winnowing Mine is also always the field that people explore.
Pneumatic separation is in air medium by the process of mineral density difference ore dressing raw material, the granularity and shape of particle Also have an impact to sorting.Compared with the wet method gravity treatment in aqueous medium, pneumatic separation does not consume water, and product need not be dehydrated, can Concentration, filtering, drying course are reduced, freezeout will not occur for winter transport;And pneumatic separation device structure is simple, base It builds expense and cost of management is relatively low.Therefore, when being suitble to dry process for some drought and water-scarce areas and raw material, pneumatic separation has Important meaning and wide foreground.
Pneumatic separation can be used for the ore dressing of part non-metallic ore, such as the separation of asbestos, mica and gangue, especially exist In terms of the sorting recycling of mica.
Mica is a kind of rock-forming mineral, and surface smoother, adhesive force is big, and radius-thickness ratio is big, and purposes in the industry is very Extensively.Contain other impurity in most mica, therefore ore dressing need to be passed through and handled.It is industrial mainly directly to utilize mica certainly Right crystal pro cessing does not have defective mica crystal bigger, economic value is higher, therefore in mica ore beneficiation at required product In the process, mica natural crystal is protected not to be damaged as much as possible.Ore dressing for mica, the past is mainly according to mica crystal It is carried out with difference of the gangue in terms of shape and friction coefficient, traditional method has picking, friction ore dressing, shape separation etc..
Picking refers to worker on face or near coal-mine ore storage, sorts the mica of monomer separation;Mica and arteries and veins The intergrowth of stone is broken into pieces with hand hammer, then selects mica therein;This method cost of investment is less, but bothersome laborious, and labour is strong Degree is very big.Friction ore dressing refers to the rolling friction system according to the coefficient of sliding friction and perfectly round shape gangue of the mica crystal of slabbing Several difference, and mica crystal and gangue is made to detach;Device therefor is friction plate;The preparation equipment that rubs is not perfect, therefore In mica ore beneficiation, which is not yet received extensive use.Shape separation be it is different from the shape of gangue according to mica crystal, It is different through the screen slot of sieve, the ability of sieve pore in screening, so that mica and gangue is detached;Device therefor be it is two layers a kind of or more no With the sieve of compass screen surface structure;The disadvantage is that easily sorting, mineral mixing phenomena be not heavier for heavy mineral and light mineral.
It is summed up, following two hang-up has been primarily present in traditional mica beneficiation method and equipment:1, it is suitable only for The big mineral of granularity, cause the waste of resource serious, and production capacity is low, and the rate of recovery is low, and cost is high;2, treating capacity is small, if Standby more, technique is discontinuous, it is difficult to enlargement, large-scale production cause the irregular replacement of consumptive material, great work intensity, sort at This height.The presence of these problems pushes continuously improving for screening installation to be created with utility model.And pneumatic cleaner is according to mine The different principle of object regular shape stress is making full use of resource, is improving production capacity, the improvement rate of recovery, increase treating capacity, reduction consumption Material, reduction labor intensity, reduction production cost etc., which have, significantly to be improved.Therefore, this just gives winnowing Mine provides the space of application development, while also proposing higher requirement to pneumatic cleaner.
The core of pneumatic separation technology is pneumatic cleaner, and properity directly influences separating effect.If wind-force Ore separators can further make a breakthrough, and the utilization for domestic and international mica resource will be undoubtedly revolutionary variation.
In view of this special to propose the utility model.
