Abstract
The utility model discloses a grader impeller, including the impeller shaft, the impeller shaft both sides are fixed with the blade through the support arm, are equipped with the wind -guiding cap between impeller shaft tip and the blade, impeller shaft surface cover has the impeller axle sleeve. The utility model discloses compare with the conventional art, through the improvement to the impeller, improved the crushing precision of grader, can adapt low fineness requirement.
Description
Technical field
This utility model belongs to mechanical field, is specifically related to a kind of classifier impeller.
Background technology
Grader is widely used in ore dressing plant with ball mill that to be made into closed cycle journey point journey shunting ore deposit husky, or is used in gravity mill and in classification ore in sand form and thin mud, and metal beneficiation flowsheet to carry out ore pulp the operations such as the desliming in grading, and washup operation, dehydration.These facility have simple in construction, reliable operation, the feature such as easy to operate.The impeller smashing fineness of additional fractionation machine is the highest, is not suitable for the needs of rigorous.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of classifier impeller.
Technical scheme: in order to reach foregoing invention purpose, this utility model is specifically performed by: a kind of classifier impeller, and including impeller axle, impeller axle both sides are fixed with blade by support arm, being provided with wind-guiding cap between impeller shaft end portion and blade, described impeller axle surface is cased with impeller sleeve.
Wherein, described blade is ring-type, between be provided with blade, blade forms acute angle, ∠ α as shown in Figure 2 with blade radius.
Wherein, the number of described blade is 120～180.
Wherein, the number of degrees of described angle are 13～15 °.
Beneficial effect: this utility model, compared with conventional art, by the improvement to impeller, improves the pulverizing precision of grader, it is possible to adapt to low fineness requirement.
