1. Introduction. Hydroxyapatite (HAp) is widely used in biomedical applications, especially in orthopaedic, odontology, as well as a coating material for metallic implants .HAp is made up of 70% bone, while collagen comprises of 20% and water makes up 10% .HAp has a chemical formula of Ca 10 (PO 4) 6 (OH) 2 instead of Ca5(PO4) 3 (OH) because it contains …

On the other hand, the impact speed is the only parameter with which it is possible to effectively change the stress condition in a particle, which is why impact mills usually run at high peripheral speeds of up to 150 m/s. When two rotors are driven to rotate in opposite directions, relative speeds of up to 250 m/s can be achieved.

1. High Efficiency: Under the same finished final size and the same motor power, the capacity of ultra fine grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%. 2. Energy Saving: compare with the comon stone powder grinding machine, the HGM minerals grinding machine can decrease about 20%~30% electrinic consums.

The apatite crystallite size exhibits the same behavior in the process of synthesis for all samples: CSRs increase up to the 20th min of mechanical impact to further reach a plateau with 5-nm fluctuations in their values . The changes in the unit cell parameters of apatite in the process of synthesis argue for its incompletion.

Hammer Milling. Hammer Mills use mechanical 'in-air' impact forces to transform bulky raw materials into uniform particles. The key variables controlling particle size are rotor speed, screen size & geometry and feed throat. Fitzpatrick Hammer Mills produce the smaller PSDs and are more suited to abrasive and difficult to mill products.
