THE EFFECT OF GRINDING TIME ON THE SPECIFIC SURFACE AREA DURING INTENSIVE GRINDING OF MINERAL POWDERS

Abstract: the changes of BET surface area of a mineral substance during intensive grinding process. Validity of the proposedmodel was tested by the experiments performed using a natural chalcopyrite mineral as well as the published data. Itwas shown that the model can predict the experimental results with a very good accuracy and can be used to predictwhat may happen under the similar experimen...

Assessment of Working Conditions of Grinding Wheels in the Grinding Process of Hard-To-Cut Materials

Abstract This study here by presents a method for comparative assessment of grinding wheels during the grinding process of hard-to-cut materials. The method in question consists of carrying out a short grinding cut in plunge grinding kinematics using grinding wheels with a customized macro-geometry upon the active surface. The work presents examples of this method’s efficacy when applied to the...

Study on Experimental and Modeling of Rotary Roll Dressing of Grinding Wheels

Two of the important parameters in grinding operation are surface roughness of the workpiece and the amount of consumed energy. These parameters are strongly affected by the condition of grinding wheel surface which is dependent on the dressing parameters. Predicting the roughness of the grinding wheel surface after dressing with known dressing parameters can improve the grinding process. Resea...

The coolant penetration in grinding with segmented wheels—part 1: mechanism and comparison with conventional wheels

This paper aims to study the mechanism of coolant penetration into a wheel-work contact zone when a segmented or conventional wheel is used in surface grinding. Based on the principles of fluid motion and considerations of spin-off and splash, analytical models for both conventional and segmented wheels were developed for predicting the power of pumping coolant into the contact zone. It was rev...

In-Process Electrical Dressing of Metal-Bonded Diamond Grinding Wheels

A new development of hybrid in-process electrical dressing of metal-bonded diamond grinding wheels is proposed in this paper. The electrical dressing method is used for overcoming the limitations of the conventional dressing methods available in relation to a super-abrasive wheel because of the hardness of its abrasive grains and the durability of its bonding material. The proposed hybrid in-pr...
