Automated online measurement of limestone particle size
Fully automated online measurement of the size distribution of limestone particles on conveyor belt is presented based on 3D range data collected every minute during 13 h of production. The research establishes the necessary analysis and measurement capabilities to facilitate automatic control of rock crushing or particle Aggregate size and shape measurement is comparatively difficult but has a larger impact on concrete properties. Four methods are available to estimate the size and shape characteristics of particles. The accuracy of each method depends on the particle sizes. Aggregate size varies from 0.15 to 25 mm for normal concrete.Measurement of Aggregate Size and Shape Using Image Analysis

The 3DPM provides online particle size distribution measurements of rock and bulk material through 3D measurements on conveyor belts. With the latest in laser triangulation hardware, the measurement module of the new generation 3DPM makes it possible to measure particles at higher belt speeds, using lower strength lasers, and Particle size measurement has been studied by means of laser light scattering, wet sieving (45, 63 and 125µm) and static image analysis. This last technique enables also to characterize the shape of particles. BET adsorption and Blaine permeability methods were also used to determine specific surface area of fillers.Particle size distribution of limestone fillers:

Experimental measurement of particle crushing around
The particle-size distribution curves tend toward a self-similar distribution (approximately parallel) with an increase in the degree of particle crushing [14, 26, 37, 38, 56]. An ultimate particle-size distribution curve would result if a sand sample were subjected to large mean stresses and shear strains [14, 42, 49].The obtained fractal dimensions of the particle size distributions for the particles crushed by the jaw, cone, and roll crushers were in the range of (2.16–2.38), (2.13–2.31), and (2.23–2.46Comparison of particle size distribution of jaw and cone crusher

The particle size distribution (PSD) results of all tested samples is presented in Fig. 1 which indicated that groups A and C were well-graded while group B was poorly graded. As mentioned in Table 1, six size ranges of CS were mixed with mass percentage method to prepare the tested materials of groups A, B, and C as shown in In order to overcome these limitations a university and industry collaboration developed three-dimensional particle measurement (3DPM) between 2006 and 2012, based on 3D surface profile measurement of the visible material on conveyor. 3DPM avoids particle delineation errors due to variation in material colour and shadows, detects overlappingAutomated, online measurement of bulk material size
