What Is a Sand Screening Machine?<\/h3>\n

A sand screening machine is specialized equipment widely used in the construction industry, especially in foundation works and bored pile drilling. Its primary function is to separate solid particles of different sizes from slurry mixtures\u2014typically drilling slurry such as Bentonite. As a result, the machine helps reuse the slurry efficiently, reduces waste, and ensures construction quality.<\/p>\n

Structurally, a sand screening machine typically consists of a screening frame, screening mesh (single-deck or multi-deck), a vibration-generating unit (usually a vibration motor or rotating shaft), a feed hopper\/chute, and a discharge system for solids. With this design, when slurry containing sand and mud is fed into the machine, the vibration or rotation causes particles larger than the mesh openings to be retained, while the slurry and finer particles pass through and are collected for reuse.<\/p>\n

On today\u2019s market, sand screening machines are available in multiple types based on capacity, screening method (vibratory or rotary), number of screen decks, and the ability to integrate additional treatment systems such as recirculation pumps or centrifuges. This allows users to flexibly select equipment suitable for the scale and characteristics of each specific project.<\/p>\n

Beyond bored pile drilling, sand screening machines are also used for sand processing in construction material extraction, industrial waste treatment, and concrete block production. Thanks to their wide applicability and proven efficiency, sand screening machines have become essential equipment in modern construction fleets.<\/p>\n

Operating Principle of Bentonite Filtration Systems<\/h3>\n

In bored pile drilling projects using Bentonite slurry, reusing slurry after it becomes contaminated with impurities is a critical technical step. If slurry is not properly treated, particles such as mud, sand, and soil debris can reduce borehole wall stability and may even cause borehole collapse\u2014directly affecting construction quality.<\/p>\n

Bentonite filtration systems are designed to solve this issue by removing solid impurities larger than the allowable threshold. The main operating principle relies on particle size classification using screen meshes together with vibration or rotation:<\/p>\n
