Abstract
The invention discloses a phosphate ore crushing apparatus which is composed of a crude-crushing cone crusher (1), a fine-crushing cone crusher (2), a screening apparatus (3), a wet-type ball mill (4), a back-conveyor belt apparatus (5) and a water supply pipe (6). The fine-crushing cone crusher (2), the screening apparatus (3) and the wet-type ball mill (4) are successively arranged behind the crude-crushing cone crusher (1). The back-conveyor belt apparatus (5) is arranged between the screening apparatus (3) and the fine-crushing cone crusher (2). The water supply pipe (6) is connected to the wet-type ball mill (4). The phosphate ore crushing apparatus is high in crush efficiency, is stable in discharged-material granularity and can ensure a granularity requirement at the inlet of the ball mill so that the ball mill is high in ore-milling efficiency. The phosphate ore crushing apparatus is less in damage on the mill, is less in ball consumption and can increase the utilization rate of raw ore.
Description
Technical field
The present invention relates to rock phosphate in powder crushing mechanism field, especially a kind of rock phosphate in powder breaker.
Background technology
In the production process of phosphoric acid product, the fragmentation of rock phosphate in powder and ore grinding are important procedures.In existing production procedure, the many employings of coarse crushing " jaw crusher ", many employings in small, broken bits " hammer counterattack is broken ", this mode crushing efficiency is low, outlet grain size is unstable, can not ensure into mill requirement, causes " wet ball mill " grinding efficiency low (65%), and it is large to the infringement of grinding machine, ball consumption, up to 0.75kg/t raw ore, therefore, is necessary to make improvements.
Summary of the invention
Object of the present invention will provide that a kind of crushing efficiency is high exactly, outlet grain size is stablized, and ensure that into mill requirement, make ball mill grinding efficiency high, and, ball little to the infringement of grinding machine consumes low phosphoric acid ore pulp produces crashing system device, it had both avoided the waste of raw ore, turn improved the rock phosphate in powder breaker of the utilization rate of raw ore.
The object of the invention is that adopted following technical scheme realizes: a kind of rock phosphate in powder breaker, is made up of coarse crushing gyratory crusher, gyratory crusher in small, broken bits, screening plant, wet ball mill, feedback belt dressing, feed pipe.Be arranged in order after coarse crushing gyratory crusher and arrange gyratory crusher in small, broken bits, screening plant and wet ball mill, feed back belt dressing between screening plant and gyratory crusher in small, broken bits, feed pipe is connected with wet ball mill.
Advantage of the present invention and beneficial effect are: principle that this technology is focused on " heavily broken light mill ", after thick, fine crushing are used instead " gyratory crusher ", crushing efficiency is high, outlet grain size is stable, and ensure that into mill requirement, through measuring and calculating, " wet ball mill " grinding efficiency reaches 90%, ball consumption is down to 0.41kg/t raw ore, with 1,200,000 tons/year of flotation of phosphate rock production scales, only " ball consumption declines " annual steel ball 408 tons, saving money of saving is through millions of unit, reduce the production cost of product, improve economic benefit.

Detailed description of the invention
By the following examples, the present invention is described in more detail, as long as but within the scope of main idea of the present invention, be not limited in following examples.
A kind of rock phosphate in powder breaker, is made up of coarse crushing gyratory crusher (1), gyratory crusher in small, broken bits (2), screening plant (3), wet ball mill (4), feedback belt dressing (5), feed pipe (6).Be arranged in order after coarse crushing gyratory crusher (1) and gyratory crusher in small, broken bits (2), screening plant (3) and wet ball mill (4) are set, feeding back belt dressing (5) is positioned between screening plant (3) and gyratory crusher in small, broken bits (2), and feed pipe (6) is connected with wet ball mill (4).
Operation principle of the present invention is: above-described embodiment is only one of preferred embodiment of the present invention; not limit the scope of the invention with this; therefore: all equivalence changes done according to shape of the present invention, structure, principle, all should be covered by within protection scope of the present invention.
Claims (1)
1. a rock phosphate in powder breaker, by coarse crushing gyratory crusher (1), gyratory crusher in small, broken bits (2), screening plant (3), wet ball mill (4), feed back belt dressing (5), feed pipe (6) formed, it is characterized in that: be arranged in order after coarse crushing gyratory crusher (1) and gyratory crusher in small, broken bits (2) is set, screening plant (3) and wet ball mill (4), feeding back belt dressing (5) is positioned between screening plant (3) and gyratory crusher in small, broken bits (2), feed pipe (6) is connected with wet ball mill (4).
