The effect of ball milling process on the properties of the natural local clay including structural changes and adsorption capacity for the removal of Ni(II) ions from aqueous solutions, was investigated. The local clay was ground at varying times from 5 to 20 h with a 10:1 or 20:1 weight ratio of the balls to powder, which produced six different ball milled clays (BMClay1 to BMClay6).

During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.

A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working ...

The principle of wet ball milling involves the energy transfer between the grinding media and the material being ground. Wet ball milling has several advantages over dry ball milling, including better efficiency, finer particle size distribution, and suitability for grinding abrasive materials. However, it also has some disadvantages, such as ...

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

Fig. 1 a shows the oscillatory ball mill (Retsch® MM400) used in this study and a scheme (Fig. 1 b) representing one of its two 50 mL milling jars. Each jar is initially filled with a mass M of raw material and a single 25 mmdiameter steel ball. The jars vibrate horizontally at a frequency chosen between 3 and 30 Hz. The motion of the jar follows a quasistraight line with a periodic signal ...

Dry ball milling is also a widely used technique for the mixing of the cathode components for ceramic batteries. The main problem of inorganic all solidstate batteries relies on the existing weak contact between the electrode and solid electrolyte, which induces a large transfer resistance among the cathode components, worsening the rate ...

(YLaCeNdGd) 2 O 3+β highentropy rare earth oxides (HEREOs) were synthesized using both mechanochemical (ball milling) and chemical (solgel) methods. Energydispersive Xray spectroscopy revealed that the compositional uniformity of the assynthesized powders was the highest in the solgel process, followed by that in wet milling and dry milling.
