The breaking force of tablets is commonly called hardness in the pharmaceutical literature; however, the use of this term is misleading. In material science, the term hardness refers to the resistance of a surface to penetration or indentation by a small probe. The term crushing strength is also frequently used to describe the resistance of tablets to the …

When used for bulk crushing strength tests, the device determines the resistance to crushing of a bed of grains whose maximum dimension is 6mm. The equipment complies with the ASTM D7084-18 and SMS …

The tablet crushing strength was increased by reducing the deviation of the granulation loss-on-drying from approximately 4.6 %; by a reduction of the fine fraction; by decreasing the lubricant concentration; or by increasing the compression force. The fraction larger than 0.300 mm had no significant influence; nor did the pre-compression.

Waste plastic film often contains an abundance of impurities, such as crop stems and soil. To address this issue, a toothed-plate single-roller crushing device for waste plastic film was developed. By analyzing the movement and force pattern of the film, the feeding speed, the number of toothed plates, and the crushing roller rotation speed …
