Optimising biomass milling classification conveying

项目摘要

This project will explore the fundamental link between biomass milling, classification and conveying to optimise biomass processing. The project will explore the fundamental science of milling fracture mechanics to develop a test for the critical particle size for comminution through compression for biomass particles. This test will be bench marked against the industry standard bond work index milling test and milling in a lab scale vertical spindle mill.The fundamental science behind classification will be investigated to ascertain the impact of biomass particle size and shape on classification and linked back to milling fracture mechanics. A model will be developed which can predict if classification will be successful based on the milled product from the grinding bed. An existing rig which examines biomass conveying in pipes will be further developed to analyse a wide range of biomass particle flow conditions.A novel biomass particle roping rig will be built to investigate roping and its link to biomass particle size and shape. Roping mitigation strategies will be developed, which will then be verified on a laboratory vertical spindle mill with pneumatic classification.This would be a four-year project based in the new Resilient Decarbonised Fuel Energy Systems CDT based at The University of Nottingham and working alongside Net Zero Research partners.

该项目将探索生物质研磨，分类和输送之间的基本联系，以优化生物质加工。该项目将探索粉碎断裂力学的基础科学，以开发生物质颗粒压缩粉碎临界粒度的测试。该测试将与行业标准粘结功指数研磨测试和实验室规模的立轴磨机中的研磨进行基准标记。将调查分类背后的基础科学，以确定生物质颗粒尺寸和形状对分类的影响，并将其与研磨断裂力学联系起来。将开发一个模型，该模型可以根据研磨床的研磨产品预测分级是否成功。现有的生物质管道输送试验台将进一步发展，以分析各种生物质颗粒的流动条件。一种新型的生物质颗粒绳系试验台将被建造，以研究绳系及其与生物质颗粒尺寸和形状的关系。将制定减少结绳的策略，然后在实验室立式主轴磨机上进行验证，并进行气动分级。这将是一个为期四年的项目，基于诺丁汉大学新的弹性脱碳燃料能源系统CDT，并与Net Zero Research合作伙伴合作。
