Essa® Pulverising Mill Bowls are a high-production, high-capacity bowl – 50 to 5000 cc nominal capacity – that are a world-leading unique range and proven performer for over 30 years. Over this time many millions of samples have been efficiently processed – they remain the bowl of choice in most of the world's leading assay labs.
Tungsten Carbide Pulverising Mill Bowl. Tungsten carbide is the grinding head of choice for many laboratories where elemental contamination is limited to just two principal contaminants: tungsten and cobalt. With the Essa 125cc grinding head all surfaces in contact with the sample (bowl, ring, roller and lid) are machined from tungsten carbide.
Principle of Operation Bowl Mill is driven by AC motor, coupled with flexible coupling to the worm shaft. The worm shaft drives worm gear, mounted on the Main Vertical Shaft. A bowl mounted on the top of the shaft rotates at a speed of 40 to 65 rpm. For a particular mill the speed is constant .Integral coolers are provided in the mill base with ...
Aug 29, 2007 We have 8 Raymond Bowl Mill pulverizer and have the same problem on only one of the mills. I have noticed that the ing mill oil has to be changed more often than others due to increased oxidation (higher TAN). The oil moves up the vertical shaft via a groove on the vertical shaft. I believe this is called an akeli pump
