A powder material application apparatus capable of applying powder material uniformly onto lower surfaces of plural upper punches, upper surfaces of plural lower punches and inner circumferences of plural dies of a tabletting machine. Powder material is applied on a material contacting surface of the lower punch by spraying powder material mixed with air from a powder material spray port for lower punch of a powder material application part for lower punch. Powder material is applied on a material contacting surface of the upper punch wherein powder material is not applied enough according to gravity by spraying powder material mixed with air from a powder material spray port for upper punch while the upper punch moves from an initial end to a terminal end of the powder material spray port for upper punch. The powder material spray port for upper punch is provided along the rotary orbit of the upper punches and is elongated more than the powder material spray port for lower punch.

Coating device for powder material

A light transmission powder and granular material measuring apparatus for a continuous production line assembly is provided. A conduit line is capable of being connected to the production line to provide an alternative flow path for the powder and/or granular material. A light transmission cell is mounted in the conduit and a measurement apparatus is provided for measuring the light as it passes through the light transmission cell. A valve member can interconnect the conduit to the production line to control the flow of powder and/or granular material, whereby a measurement can be made when the valve is activated to permit the flow of powder and/or granular material to provide an accurate measurement, and also a measurement can be made as a reference measurement during a calibration cycle when the valve is activated to stop the flow of powder and/or granular material. The light transmission powder and/or granular material measuring apparatus can be provided as a modular unit for mounting in a continuous production line and can be automatically controlled to periodically calibrate its measurements.
