摘要:
A material sorting system sorts materials, such as scrap pieces composed of unknown metal alloys, as a function of their detected x-ray fluorescence. The x-ray fluorescence may be converted into an elemental composition signature that is then compared to an elemental composition signature of a reference material in order to identify and/or classify each of the materials, which are then sorted into separate groups based on such an identification/classification. The material sorting system may include an in-line x-ray tube having a plurality of separate x-ray sources, each of which can irradiate a separate stream of materials to be sorted.

The sorting method includes: an X-ray inspection step of irradiating a resin piece with X-rays including a first X-ray and a second X-ray having respective energy ranges different from each other and measuring a first transmission intensity which is an intensity of the first X-ray transmitted through the resin piece and a second transmission intensity which is an intensity of the second X-ray transmitted through the resin piece; a first determination step of making a determination as to whether the resin piece is a candidate for a useful resin piece, using the first transmission intensity; and a second determination step of making a determination as to whether a resin piece identified as a candidate for a useful resin piece in the first determination step is a useful resin piece, using a differential value obtained from the first transmission intensity and the second transmission intensity.

A method for sorting, in a continuous flow, contaminated materials, which includes: conveying materials from a point (A) to a point (B) by means of a conveyor; measuring the radioactive activity by means of a first sensor between the points (A) and (B) on the top surface (FSUP) of the first conveyor; and sorting the materials by means of a sorting device. The method may include measuring the radioactive activity of the contaminated material by means of a second sensor, either on the top surface (FSUP) of the conveyor and upstream from the point (A), or below the bottom surface (FINF) of said conveyor; calculating a differential measurement between a measurement from the second sensor and from the first sensor; and restricting the sorting to the comparison between a threshold value and the measurement from the first sensor or the differential measurement.

The invention relates to a device (10; 10a) for controlling pharmaceutical products (1) in particular, hard gelatin capsules, by means of a radiation source (11) preferably designed as an X-ray source, comprising a storage device (13) which receives the products (1) in an uncontrolled manner, and from which the products (1) are transferred to a transport element (15) in which the products (1) are arranged such that they form at least one row. The products (1) are transported in a clocked manner in the radiation area (25) of the radiation source (11) which exposes the products (1) to radiation, preferably perpendicular to the longitudinal direction thereof. A first stopping device (20) for separating the products (1) in the row is arranged upstream of the radiation source (11) in the direction of transportation (18) of the products (1), and at least one sensor element (28, 28a) coupled to an evaluation device (30) captures the radiation which passed through the products (1). According to the invention, at least two products (1) are separated from the row by means of the first stopping device (20) and are simultaneously positioned in the radiation area (25) and the image of the product (1) is captured by means of the at least one sensor element (28; 28a).

Disclosed herein is the use of differences in x-ray linear absorption coefficients to process ore and remove elements with higher atomic number from elements with lower atomic numbers. Use of this dry method at the mine reduces pollution and transportation costs. One example of said invention is the ejection of inclusions with sulfur, silicates, mercury, arsenic and radioactive elements from coal. This reduces the amount and toxicity of coal ash. It also reduces air emissions and the energy required to clean stack gases from coal combustion. Removal of said ejected elements improves thermal efficiency and reduces the pollution and carbon footprint for electrical production.

The method relates to the field of mineral enrichment. It involves establishing threshold values of the intensity of a luminescence signal arising during the action of a pulse of exciting radiation on a material being separated and after a specified time following the end of the exciting pulse, and, during the processing of the recorded signal, first of all determining the value of the intensity of the luminescence signal, comparing the value obtained with the specified threshold value and, in the event of the threshold value being exceeded, processing the signal in order to determine the value of the selected separation criterion, comparing the processing result with the specified threshold value and isolating the mineral to be enriched from the material being separated if the comparison result satisfies the specified criterion; in the event of the value of the intensity of the luminescence signal after a specified time following the end of the exciting pulse being less than the threshold value thereof, determining the value of the intensity of the luminescence signal arising during the pulse of exciting radiation, comparing said value with the threshold value specified therefor and isolating the mineral to be enriched from the material being separated if the threshold value is exceeded.

The present invention relates to a method for separating mineral impurities from calcium carbonate-containing rocks by comminuting the calcium carbonate-containing rocks to a particle size in the range of from 1 mm to 250 mm, separating the calcium carbonate particles by means of a dual energy X-ray transmission sorting device.
摘要:
A system and method for sorting of objects that includes a pathway network that has a plurality of pathways and one or more branch points. A fluid composition including one or more objects can be transported through the pathway network, where one or more of the objects are analyzed and sorted at one or more branch points based on the analysis of the objects.

In order to check hand luggage and other objects carried by persons, control stations are needed, which have a control unit, in particular an X-ray checking unit, a conveyor which extends through the control unit, a depositing point which is arranged ahead of the conveyor, and a removal point which is arranged behind the conveyor, for the objects and having transport tubs which can be placed onto the conveyor. Small objects and items of clothing are placed in the transport tubs and conveyed through the control unit for checking. A return conveyor for the transport tubs is arranged next to or below the conveyor which passes through the control unit, which return conveyor reaches from the removal point behind the conveyor at least as far as into the region of the depositing point ahead of the conveyor.
摘要:
An automated multi-grade wastepaper recycle center and sorting system is provided. The center is a multi-acre fenced-in complex having security that allows for recycling trucks to deliver multiple grades of wastepaper for separating and sorting to one location prior to pulp processing and deinking type processes. Collection tracks leave their loads in one of four drop pits where different conveyor systems start the sorting process. A novel swivel conveyor system can remove papers from the drop pit for temporary storage on various locations on a primary segregation floor where plied papers can later be recycled into main pit area when needed. Alternatively, loads from the drop pits can be conveyed to the main pit area directly and then presorted onto different conveyor systems. One conveyor can then send wastepaper through a star-wheel sorter system that can separate desired grades of paper. Another conveyor can pass papers through an x-ray station and then hand separated through specialized waste collection stations and drops. Sorted papers can later be sent to a bailer system for bailing and/or separated papers can also be resorted through the various sorters over and over as needed. The bailed papers can later be sent to additional outside recycling processes such as but not limited to deinking and the like. The complex allows for the bailed papers to be delivered to the additional recycling locations such as ones for pulp processing and deinking operations by railroad lines and/or also by trucks.
