The Silver Bell Mine is located in the Hexie Mountain range, within Joshua Tree National Park. Two gigantic tipples (ore bins) are still standing. The mine was known to have operated for about 40 years, though ownership and details about the mine's riches are sketchy. This was a versatile mine: gold in the 1930s, lead in the 1940s, and copper in the 1950s.The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed


In January of 2003, The Mill of Bel Air merged with Service Feed & Supply in Delta to create The Mill of Whiteford. Service Feed & Supply housed the Mill's bulk materials until recently.
