Abstract
The utility model relates to an impurity and mineral separation device used in a bentonite smashing process. The impurity and mineral separation device comprises a Raymond mill with a grinding roller and a grinding ring arranged inside, wherein a slag discharging port with the size controllable is arranged at the bottom of the lateral surface of the Raymond mill. Minerals (including quartz and feldspar) which are large in specific gravity can be automatically separated by means of cyclone generated by a suspended roller during the smashing process when the impurity and mineral separation device works, and the aim of purifying montmorillonite from the bentonite can be achieved. The impurity and mineral separation device is simple in structure and convenient to use, does not need to further add an air-selection separation device on a material outlet by means of the improved Raymond mill, reduces cost and energy consumption of devices, can perform lower portion slag removing on the Raymond mill without shut down, greatly improves the purification effect of the bentonite, has high economic benefit and is easy to popularize and use.
Description
Technical field
The utility model belongs to the object separating device technical field, relates to the impure mineral separator in a kind of bentonite pulverizing process.
Background technology
In the prior art; Traditional bentonite dry purification generally all is after utilizing Raymond machine (also claiming Suspension roller pulverizer or swing type disintegrator) that ore is all pulverized; Again according to the mineral difference of specific gravity; The special equipment of taking behind the Raymond machine discharging opening, to be provided with (like whirlwind clarifier) carries out the selection by winnowing separation, thus the effect that realizes improving smectite content.The problem that exists is: because the crushing process of existing Raymond machine equipment is totally enclosed; Can't in crushing process, reject different specific weight mineral constituent; Pulverize the heavy mineral in back and all be deposited on the Raymond machine side bottom, and ground repeatedly by Raymond machine and to become product, the minority deposit only could be with it removing when Raymond machine is shut down; Process is loaded down with trivial details, has influence on the The Purification of Swelled-ground effect to a great extent.
Summary of the invention
The purpose of the utility model is the problem that prior art exists is solved; And then the impure mineral separator in a kind of bentonite pulverizing process is provided; Utilize this separator can make bentonite pulverize the bigger mineral of back proportion easily and separate automatically, realize the effect of montmorillonite in the efficient purification bentonite.
For realizing that the technical solution that the foregoing invention purpose adopts is such: the impure mineral separator that is provided comprises the Raymond machine of establishing grinding roller and bull ring in one, it is characterized in that having in the side bottom of Raymond machine the slag-drip opening of a controllable size.During device work; Grinding roller tightly is pressed on the bull ring under centrifugal action; Form an abrasive power; The material that gets into Raymond machine is pulverized under the effect of rolling of this abrasive power; After following of the effect of blower fan becomes the lighter material (montmorillonite) of proportion of powder to blow afloat and is, receive collection equipment afterwards and collect, separate in the slag-drip opening that the slag charge that proportion is bigger (quartz, feldspar etc.) is then opened by the side bottom of Raymond machine under the whirlwind effect that overhang roll self produces, reach the purpose of montmorillonite in the purification bentonite.
Compared with prior art, the utility model simple in structure, easy to use is after improving through Raymond machine; Need behind the Raymond machine discharging opening, not increase the selection by winnowing separator again; Reduced equipment cost and energy consumption, and Raymond machine bottom slag charge is removed also to need not to shut down and is carried out, and has improved the Purification of Bentonite effect greatly; Have high economic benefit, be easy to promote the use of.
Description of drawings
Accompanying drawing is the structural representation of a specific embodiment of the utility model.
The title of each number designation is respectively among the figure: 1-Raymond machine, 2-grinding roller, 3-slag-drip opening, 4-bull ring, 5-charging aperture.
The specific embodiment
Referring to accompanying drawing; Impure mineral separator in the described bentonite pulverizing of the utility model process comprises the Raymond machine 1 of establishing grinding roller 2 and bull ring 4 in one; Having one in the side bottom of Raymond machine 1 can be through the slag-drip opening 3 of mechanism controls openings of sizes such as regulation and control door; During work; Utilize the whirlwind that overhang roll self produces in the crushing process to make the bigger mineral of proportion (quartz, feldspar etc.; Among the figure with
symbolic representation) separate automatically, reach the purpose of montmorillonite in the purification bentonite (among the figure with the symbolic representation).
This device uses in actual production, when pulverizing bentonite, can the smectite content of montmorillonite product be increased to 89.8% by 82.4%, and effect is obvious.
