Third Generation Computerized Particle Analyser
The new HAVER CPA 2-1 HR with optimized hardware measurement process and cover
They work with partners from the Haver & Boecker Group in the development and improvement of CPA technology. These include the Machinery Divisions in M
HAVER & BOECKER is a traditional family-operated, medium-sized company with headquarters in Oelde, Westphalia, Germany. The Wire Weaving and Machinery Divisions are under the umbrella of HAVER & BOECKER OHG, which, together with over 50 subsidiaries on all five continents, comprises the HAVER Group with more than 2,870 employees and 150 representatives worldwide. In 2013, the HAVER Group realized a turnover of 470 million euros. The Wire Weaving Division manufactures woven wire mesh and processes it into engineered woven wire products, which are used for screening and filtration in the chemical, plastics and automotive industries, in the fields of aviation, aerospace and electronics, for industrial screening and particle size analysis, and in the foodstuffs industry as well as for architectural applications. The Machinery Division specialises in packing and weighing technology. It develops, produces and markets systems and plants for filling and processing of all types of bulk material. The product range includes packing and loading systems for powder-type and granulated bulk materials, packing machines for filling foodstuffs and animal feed, as well as filling stations and complete filling lines for liquid and pasty products. Screening machines, washing systems and pelletizing plates, agitators and mixers, palletizing and loading systems, in addition to silos, ship loading and unloading equipment complement the product portfolio.
When it comes to analysing particle shape and size HAVER & BOECKER not only stands for top quality, but also for patented innovation. This year there is the new generation HAVER CPA 2-1 and HAVER CPA 2-1 HR laboratory instruments.
The entire hardware measurement process has been overhauled and improved. The process, from material input to discharge into the measurement zone, has been optimised. As a result handling is easier and faulty operation is practically eliminated. And in order to better protect the measurement zone from external disturbances, a cover has been integrated as a standard feature for both instrument types. The cover allows quick and easy access.
Another interesting development with the HAVER CPA 2-1 HR is the optimised chute geometry, which once again improves the resolution of the agglomerate and makes material conveying more uniform. This allows perfect measurement quality to be maintained despite increased measurement speed. Moreover both the HAVER CPA 2-1 and the HAVER CPA 2-1 HR can operate with an integrated ultrasonic support. With this combination not only is the measurement time optimised, but also the application spectrum can be further expanded to include more difficult materials.
The proven line-scan camera technology is also able to extend its advantage over other dynamic particle analysis methods. For the customer, this means falsified results arising from unmeasured sampling parts are excluded. Furthermore, there is no double measurement of particles, which occurs with matrix cameras and especially with multiple camera systems. As a result, excellent reproducibility and measurement quality are achieved also with the smallest sample sizes. In addition, the exchange of feed chutes, measurement range switchovers and adjustments are unnecessary. HAVER CPA offers a constant level of measurement quality for each individual particle over the entire measurement range at no additional expense.
