A method and device for measuring agglomeration strength parameters of granular materials through a single solid bridge

Abstract

The present invention involves a method and device that measures the block intensity parameters that measures the particle material through a single solid bridge. Two particles are fixed through the device, and the temperature controls the wet to generate a single solid bridge.And use external forces to destroy the solid bridge, so as to use formula σ = c / πb 2 Or σ = g / πb c 2 Calculate the block intensity parameters of the material.Among them, σ is the block intensity parameter of the particle material, B is the radius of the solid bridge, and C is the force required for the solid bridge with a broken radius of B, that is, the block intensity; c The radius of the critical solid bridge.The device consists of a temperature control wet box, a fixed particle device and a microscope.The fixed particle device can be a dual -robotic arm pressure sensing, lifting, platform decrease, vibration and other forms.This method has the advantages of more accurate physical significance and credibility, high accuracy, strong repetitiveness, short measurement cycle, small sample consumption, and high -throughput.

Description

Technical field [0001] The present invention involves a measurement method and device, especially the method and device that involves a method and device that measures the block intensity parameters that measures the particle material through a single solid bridge. Background technique [0002] Solid particles are a very common product form in industrial production. In the fields of medicine, chemistry, food, fertilizer, cleaner, military industry and other fields, solid products are more inclined to be prepared into a single and decentralized state to have good liquidity and stability, thereby improving business competitiveness. However, in the downstream process of granular products (filtering, washing, drying, transportation, storage, and sales), the phenomenon of mass is very easy to occur, resulting in the loss of liquidity and stability of the product, significantly reduced product value, and increased production and use costs. The universality and harm of the block problem...

Problems solved by technology

In terms of the consumption of test samples, the consumption of the bagging method is huge, and the single consumption of the accelerated agglomeration method is also at the level of 100 grams. Such a high consumption is almost unbearable for some precious samples.

In terms of measuring devices, the bagging method occupies a large area and cannot be adjusted for temperature and humidity; the sample preparation device for the accelerated test method is often relatively large, and in a conventional temperature and humidity control box (0.5 to 1 cubic meter of space) ) can only place one sample preparation device, and cannot achieve multi-throughput

[0010] Therefore, in order to solve the problems of low accuracy, long measurement period, large consumption of dosage, and difficulty in multi-throughput of the measuring device in the traditional method of measuring caking strength parameters, a method and supporting device are urgently needed to achieve efficient caking strength parameters. accurate measurement
