Modifications of this method have been developed to improve the separation of liquid from solid. For instance, simple crushing rolls of the type used for expressing juice from the sugar cane have drainage grooves (Menchaerts groves) on the roller surfaces. These grooves direct the liquors away from the compressed cake thus reducing re-wetting.

The ring crush test is similar to the short-span compression test in that the strength of the liner or fluting is measured both in the machine direction and perpendicular to it. It is important that force application to the specimen is exactly perpendicular during these tests. The results of this test are highly dependent on proper specimen preparation.


Question: FIFO Method, Valuation of Goods Transferred Out and Ending Work in Process K-Briggs Company uses the FIFO method to account for the costs of production.

Adhesion Strength of Flutes (Pin Adhesion) The adhesion strength between the flutes and liners shall reach ≥48 lbs per foot of glue


Ghani oilcake as prised out of the unit after crushing is extremely hard and is not accepted by the trade for further solvent extraction, as are expeller oilcakes. In ancient times, ghani crushers in India were recorded as being a separate caste, and this distinction still persists (Bose, 1975).


Transcribed image text: K-Briggs Company uses the FIFO method to account for the costs of production. For Crushing the first processing department, the following equivalent units schedule has been prepared. The cost per equivalent unit for the period was as follows: The cost of beginning work in process was direct materials, $40.000; conversion costs, $30,000.

Two chemical methods are commonly used: phosphatation and carbonation; both processes require the addition of lime. The phosphatation uses phosphoric acid, lime (as lime sucrate to increase solubility), and polyacrylamide flocculent to produce a calcium phosphate floc. Air flotation is usually used to separate the floc from the liquor and the floc
