Along with the industrialization inceasing development, in each domain unprecedentedly increases to the powder body demand quantity, but the existing powder body prepares of the equipment universal existence energy consumption much, the pollution environment and the smashing mechanism quite is unitary the insufficiency and so on, therefore they also wait for the further development.This article is in the ball mill, the vibration mill and the high-pressured water jet flow grinding machine and in the existing smashing installment foundation, summarizes the predecessor to experience, proposes the compound suitable water power smashing device. In this set of smashing device, the material pellet which join receives the high-pressured current of water the water wedge function and the high-pressured current of water impact function, lays the function with the acceleration pipeline between friction, with target body between collision impact function, with grinds the medium to grind, the impact function, in water body turbulent, cavitation, but also has grinds the medium with to filter between the board the friction shear action and the many kinds of factors synthesis, realizes to joins the material the smashing. This kind of mechanism and before use the mechanism which some one kind affects crushes is only entirely different.In order to analyze affects the compound suitable water power smashing device the smashing ability, this article corresponding design a set of compound suitable water power smashing system. This system is making by the dynamic system, the smashing system, the separation system, the quantity aqueous system and the backwater system,this five subsystems are composed. The smashing system is a key point which we designs, including tocrushes the box body, high-pressured water part the and so on jet flow spray nozzle, acceleration caliber, target body design and the manufacture. Flows the pressure, the current capacity, the impact time after the overall system high-pressured water jet also has grinds parameter andso on medium carries on the many kinds of combinations.We carry on drying, the name to each timeexperimental result are heavy. From empirical data which obtains, we can analyze affect the compound suitable water power smashing device of the smashing ability factor are as follows:(1)The high-pressured water jet flow power. Along with high-pressured water jet flow power increasing, after the smashing the pellet granularity can be smaller.(2)Grinds the medium in device. This article is from grinds the medium to fill in complete and theal located proportion two aspects analyzes: In the installment,certainly is not grinds the medium to join many, the smashing effectis better, but is has a best value in the quantity. The different diameter grinds the medium the bulk volume to compare to crushes theeffect to have the influence.(3) The time of high-pressured water jet flow impact. Impact time excessively long, system atically the efficiency drops, the impact time is insufficient, the smashing product quality can come under the influence. Under this experimental condition, the best of value impact time is in 5min -20min.This article also draws support the orthogonal analysis form,even direct-viewing obtains the high-pressured water jet flow power to have the especially obvious function to the compound suitable water power smashing device smashing ability.
