Abstract
The invention discloses a method for preparing dolomite particles from dolomite tailings. The method is characterized by comprising the following steps of: a) sending tailings with the radius of less than 10mm in the dolomite tailings into a circular vibrating sieve to perform a pre-screening process step; b) then enabling the tailings with the radius of 8 meshes-140 meshes to enter a finished product box; c) then crushing and shaping the tailings with the radius of more than 140 meshes by utilizing an impact type crusher; and d) then entering into a variable frequency vibrating screen, screening the tailings again to obtain the tailings with the radius of 8 meshes-140 meshes, and entering the finished product box. The pre-screening treatment is performed on the dolomite tailings with the radius of less than 10mm, then dolomite between 8 meshes and 140 meshes is collected into the finished product box, the dolomite exceeding 140 meshes is crushed and screened, the qualified dolomite is recovered into the finished product box, the unqualified dolomite is circulated into the crushing process step, and the reciprocating circulation is performed until the dolomite between 8 meshes and 140 meshes is obtained.
Description
Technical field
The present invention relates to the method that a kind of dolomite mine tailing prepares dolomite particles, especially a kind of method of utilizing the dolomite mine tailing to prepare dolomite particles.
Background technology
Dolomite is the primary solvent raw material of preparation glass, because it is a kind of natural magnesia ore, can be used for extracting raw materials of magnesium oxide.Research is found, in preparation glass process, utilizes magnesia to substitute after the calcium oxide of a part, can reduce the setting rate of glass, thereby improve the processability of glass.For guaranteeing the glass ware forming superior performance of preparation, consider to adopt the less dolomite of order number for this reason, and a large amount of tailings that produce in the dolomite recovery process, because its order is counted less, just in time can be used for preparing the dolomite of low mesh number, take full advantage of simultaneously resource, and produced certain economic benefit.
Summary of the invention
Technical problem to be solved by this invention provides the method that a kind of dolomite mine tailing prepares dolomite particles, utilizes the dolomite mine tailing to obtain super fine bitter spar.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of dolomite mine tailing prepares the method for dolomite particles, and its innovative point is to comprise the steps:
A) tailings of radius in the dolomite mine tailing less than 10mm is transported in the feeding machine by loading machine, then utilizes feeding machine that tailings is sent into the pre-screening operation that circular shale shaker carries out tailings;
B) tailings of radius between 8 orders～140 orders among the step a enters among the belt conveyor A of circular shale shaker below, enters at last in the finished product box of belt conveyor A end;
C) radius utilizes elevator to enter in the impact crusher greater than 140 purpose tailings among the step a, and tailings is carried out broken shaping;
D) tailings after the broken shaping utilizes belt conveyor B to enter into variable frequency vibration screen among the step c, tailings is sieved again, screening obtains the tailings of radius between 8 orders～140 orders, enters in the finished product box through belt conveyor C, obtains required dolomite particles;
Further, radius enters into the impact crusher of step c in the steps d by belt conveyor D greater than 140 purpose tailings.
Further, impact crusher discharging opening position is provided with deironing apparatus A among the step c, and described deironing apparatus A is mainly the circle ferromagnetic deironing device.
Further, be provided with deironing apparatus B in the described finished product box, described deironing apparatus B is mainly electromagnetic wand.
Further, among the described step b among the belt conveyor A some deflector rolls be half magnet drum.
The invention has the advantages that: sieve in advance processing by pair radius less than the dolomite mine tailing of 10mm, thereby the dolomite between 8 orders～140 orders is collected into finished product box, exceed 140 purpose dolomites through broken, screening, qualified dolomite is reclaimed into finished product box, the underproof broken process that is recycled to, reciprocation cycle is until obtain dolomite particles between 8 orders～140 orders.
By being arranged on the circle ferromagnetic deironing device of broken process impact crusher discharging opening position, the iron in the dolomite is carried out Transformatin in addition, the iron-holder in the assurance dolomite is less than 0.08%.
Some deflector rolls are half magnet drum among the belt conveyor A before the pre-screening operation, thereby the iron in the dolomite mine tailing is carried out Transformatin, and the iron-holder in the finished product dolomite that obtains when guaranteeing follow-up pre-screening operation is in 0.08%.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Diagram is the process chart that a kind of dolomite mine tailing of the present invention prepares the method for dolomite particles.
The specific embodiment
The method that dolomite mine tailing of the present invention prepares dolomite particles mainly comprises the steps: at first, the tailings of radius in the dolomite mine tailing less than 10mm is transported in the feeding machine by loading machine, then utilizes feeding machine that tailings is sent into the pre-screening operation that circular shale shaker carries out tailings.Then with the tailings of radius between 8 orders～140 orders, enter among the belt conveyor A of circular shale shaker below, enter at last in the finished product box of belt conveyor A end, obtain required dolomite particles, finish the collection of finished product.Greater than 140 purpose tailings, then utilize elevator to enter in the impact crusher for radius in the circular shale shaker, tailings is carried out broken shaping.
Utilize belt conveyor B to enter into variable frequency vibration screen the tailings after the broken shaping, tailings is sieved again, screening obtains the tailings of radius between 8 orders～140 orders, and C enters in the finished product box through belt conveyor.The radius that obtains for screening again then again circulates by belt conveyor D and enters into impact crusher greater than 140 purpose tailings, and it is carried out fragmentation, until in the dolomite tailings order number of dolomite between 8 orders～140 orders.
For ease of the making of follow-up glass, the dolomite for purifying often needs the iron-holder in the dolomite is carried out Transformatin, and the concrete three step approach that pass through are realized.The first, sieve in advance before the operation, be half magnet drum with some deflector rolls among the belt conveyor A, thereby the dolomite finished product of stipulating the order number is satisfied in preliminary acquisition, in transport process, carry out de-iron and process.Second, before the variable frequency vibration screen operation to the order number greater than 140 dolomite mine tailing, when utilizing impact crusher broken to it, be provided with deironing apparatus A in impact crusher discharging opening position, this deironing apparatus A is mainly the circle ferromagnetic deironing device, processes thereby this part dolomite mine tailing is carried out de-iron.The 3rd, deironing apparatus B is set in finished product box, this deironing apparatus B is mainly electromagnetic wand.Thereby utilize above-mentioned three steps, can so that the content that obtains iron in the super fine bitter spar below 0.08%.
