Solaris has announced the initial deployment of the company's 5-million-pound Mobile Sand Silo System. This new 12-silo system recently was used to successfully complete a 'zipper' frac of two wells on a pad in the Permian Basin. The system delivered sand at an average rate of nearly 23 000 lb per minute into two blenders simultaneously.

Chris Schaller. College of Saint Benedict/Saint John's University. About 90% of the earth's crust is composed of silicate minerals. Silicates are compounds composed of silicon and oxygen; these compounds have negative charges on them. That means there are positive counterions found together with these anions.

Bridging or arching. Materials interlock or bond together to form an arch above the outlet, blocking any flow. The strength of this arch depends on the cohesive strength and internal friction of the particles. Hammering or blasting with an air cannon can break the arch, but this can overload and damage the vessel.
