Because of the high hardness and poor wear resistance of steel slag, the potential cementing property of steel slag can not be effectively exerted, and the utilization rate of steel slag. Is low. In order to improve the performance and grinding efficiency of steel slag powder, different grinding aids were added in the process of steel slag grinding in laboratory and production line respectively.

This effect is slightly visible for the bulk densities but for both grinding processes . The addition of binder affects mainly the gross density and only in the impact grinding process. One remarkable aspect is that an increase of the gross density can be seen only for the pellets with a miscanthus share of 0 and 0.1 kg kg −1.

Effect of grinding depth. The four flanks A 1, A 2, B 1, and B 2 are each generated by one wheel in the machining process and the grinding depth therein is varied to provide a certain angle between the flank and workpiece end-surface. In the micro-drill bit, the grinding depth is minimal and near-zero (at least in theoretical terms).

Grinding is one of the effective manufacturing processes with which to produce highly accurate parts with an ultra-fine surface finish. The tool used to remove materials in grinding is called the grinding wheel. Abrasive grains made of extremely hard materials (alumina, silica, cubic boron nitride, and diamond) having a definite grit size but a random shape are bonded on the circumferential ...

Passive grinding is a new rail grinding strategy. In this work, the influence of grinding pressure on the removal behaviors of rail material in passive grinding was investigated by using a self-designed passive grinding simulator. Meanwhile, the surface morphology of the rail and grinding wheel were observed, and the grinding force and temperature were measured during the experiment.

Grinding modes appeared to play a determinant role in final characteristics of ground wheat straw. The effect of particle size reduction was decoupled from the effect of internal changes in the lignocellulosic structure. The degradability of wheat straw was …

The excessive residual stresses caused by heat treatment and grinding processes is one of the main challenges for Cam manufacturing, because they will lead to delayed cracks and reduce the fatigue life of Cam. Experimental studies are one of the essential ways to keep residual stresses at a reasonable value. Thus, orthogonal and single-factor experiments are carried out to explore the effect ...

The grinding process was performed at different cutting speeds, feed rates, and depth of cuts. Grinding performance was evaluated by measuring forces and surface roughness of the ground GFRP composite laminate material. The effects of coolants in grinding the composite laminate material were investigated.

This study attempted to replace the wet grinding process of rice with a freeze grinding process. The freeze grinding process involved soaking the rice samples in liquid nitrogen before grinding in a dry grinding machine. Three different types of grinders (hammer mill, roller mill, and pin mill) were used in both the freeze and the dry grinding processes.

Establishment of predictive model of subsurface damage depth. The semi-consolidated abrasive grinding process can be simplified as the large-scale imprinting effect of a sharp indenter on the surface of a hard, brittle material, as illustrated in Fig. 2.Therefore, subsurface damage depth h SSD and surface roughness Rz, and their proportional relationship, can be investigated using indentation ...
