Background technology
The inherent quality of fertilizer industry product always comes into one's own, and along with the progress of production Technology, the fierceness of market competition, presentation quality more and more receive market and user's concern.In all kinds of national standards and industry standard, size indicator (being generally 1-4mm >=90%) is adopted in the description of fertiliser granulates outward appearance always, and the size indicator qualification rate reaches 100% product, still has the not problem of rounding of particle appearance.This shows that size indicator can't satisfy the client and the market demand, propose the notion of the relative roundness of granule materials at this point.
The roundness index is the quantizating index of fertiliser granulates product appearance rounding degree relatively; Be the further additional and lifting to graininess fertilizer national standard, national sector standard quality index, relative roundness is the presentation quality characteristic of characterizing particles fertilizer preferably.Best in theory fertiliser granulates, its maximum gauge is 1 with the ratio of minimum diameter, i.e. the sphere body.But present stage, fertilizer production enterprise only rested on qualitative aspect to the evaluation of particle roundness owing to the evaluation means and the method for lacking quantitative, only relied on technician's sense organ and judged that the product circle is round with, and can't accomplish quantitatively evaluating.
At present, abroad other industry has and adopts optical imaging system to carry out the assay method of granule materials roundness, mainly be applicable to the mensuration of diameter≤1mm material particles product, but instrument costs an arm and a leg, and needs 500,000 yuan approximately; And complicated operation, failure rate is high, and operation and maintenance cost is difficult to promote the use of with high, for this reason, needs exploitation a kind of simple and practical, easy and simple to handle, the relative roundness determinator of granule materials with low cost.
The utility model content
It is a kind of simple in structure, easy and simple to handle that the purpose of the utility model is to provide, and be fit to measure granule materials, is particularly suitable for measuring the determinator of the relative roundness of fertiliser granulates of diameter >=1mm.
The purpose of the utility model is achieved in that and comprises that rolling skewed slot and metering rise as high as the banks; Described metering is provided with level meter on rising as high as the banks; The tilt adjustable of described rolling skewed slot and with the metering closed butt joint of rising as high as the banks, the metering bottom of rising as high as the banks is provided with height and level(l)ing device.
The utlity model has following beneficial effect: the utility model determinator production cost is low, 1000 yuans of less thaies.Having overcome prior art---optical particulate roundness sensing equipment price is high, and only is applicable to the deficiency of mensuration particle diameter≤1mm particle roundness, is particularly suitable for the mensuration of particle diameter>=relative roundness of 1mm granule materials.Easy and simple to handle, be particularly useful for the mensuration control requirement of the relative roundness of fertiliser granulates, and operation expense is cheap.
