Roll Crushers
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.

How to Amend Clay Soil: A Gardener's Guide to Success
Clay soil consists of over 50% clay particles. These mineral particles are extremely small, measuring less than 0.002 mm in diameter. The tiny size and flat shape of the particles allow them to pack tightly together, creating heavy, dense soil. When clay soil is dry, it becomes rock solid and cracks. Wet clay soil feels slick and sticky.

It is shown that impermeable clay layers can increase arsenic input to underlying groundwater systems due to reduction of iron oxides coupled to carbon oxidation, which explains a steady rise in arsenic concentrations in a pre-Holocene aquifer below such a clay layer and the repeated failure of a structurally sound community well. Confining clay layers typically protect …
