How Portable Sand Plants Work
Whether these plants are called portable, transportable, relocatable, wheel-mounted, skid-based, mobile, modular, etc., they share common features — they go on a truck and down the road with a minimum of disassembly/reassembly for rapid (re)deployment. Often this need is for a start-up company, permitting reasons, tracking a highway project across multiple deposits and limited term demand projects, such as dams or airport construction.
While portability naturally limits capacity, it does not necessarily limit the process. These plants typically do not come complete with ancillary material handling, as most companies have available from their inventory or our dealers, but this can be included if needed.
Skid-based plants can have a variety of applications and configurations. The range of process options includes the following: scalping, liberating, sizing, pumping, washing, classifying, deligniting/organics removal, dewatering, effluent management and waste solid management.
McLanahan also has partner companies to provide other equipment such as jigs for separation of coarse organics or deleterious shales, etc. and bucket wheels for dewatering dredge type feed.
Many different types of equipment and systems can be configured on a skid base, including feed preparation equipment, such as Aggregate Conditioners, Attrition Cells and Coarse Material Screw Washers; Primary Sand Washing; Specialty Sand Production; Construction and Demolition; point-of-use applications such as processing sand filter materials; and effluent treatment with Thickeners and Filter Presses.
From a process perspective, Skid-Based and Portable Sand Plants do not work any differently than their customised cousins, they are just limited by size for transport; thus, their throughput capacity tends to be limited.
