There are only a few types of effective sand dryers out there. In general, we consider two in our designs. Fluidized bed dryers and rotary dryers. While the cost is drastically lower for rotary dryers, we have found an abundance of fluidized bed dryers being used in large scale sand operations due to their efficiency and reduced maintenance. Rotary dryers cost much less up front but we find that the long term btu requirement per ton to be higher. There is data both ways but this is generally what we see. So, pay now or pay later. A higher up-front investment in fluidized bed yields lower gas bills and operating costs long term.

The rise in demand has created a shortage of proppant that is effecting the Oil and Gas Exploration across the country. The demand for proppant has also created a shortage for frac equipment. Cabot Oil and Gas made statements in a quarterly call earlier this year that 'shortage in Frac equipment' delayed projects in the Haynesville Shale.

Frac Sand Tanks are ideal for contaminate free frac sand storage, with 45° cones for convenient and free flowing discharge. Manufactured with industrial gauge steel, Frac Sand Tanks are designed to withstand the significant weight of loading and unloading. With such features as butterfly discharge packages, fill tubes designed for convenient loading and foundations strong enough to support the silo weight.

The frac sand washing unit has been designed in order to obtain sand meeting with the requirements of industry such as grain size, fineness modulus, cleanliness, content of non desired elements (organic material, chloride, sulphate, etc.) These units are used to treat sand for frac sand, concrete as well as other industrial sands, bentonite slurry and other minerals.
