What is Frac Sand? Frac Sand is a high purity quartz sand used as a proppant in hydraulic fracking. The sand has a very high silica content (over 99% quartz) and has high strength and purity. Frac sand is extremely spherical in order to allow for better packing and fluid flow in fractures and maintain a distinct particle size when processing frac sand is imperative. Inability to meet the particle size demands of 20/40, 30/50 and 40/70 mesh can lead to blocked fractures and clogged pores which can reduce permeability. Sieving these highly spherical particles at high processing throughput rates can be a difficult task using conventional screeners & ultrasonic sives.
