In bored pile drilling and Bentonite slurry treatment, choosing the right sand screening machine not only improves construction efficiency but also significantly reduces filtration and material recirculation costs. For more than a decade, Hanoi Vietnam Co., Ltd. has been a trusted and reputable brand for both domestic and international customers. We currently provide sand screening and sand separation (desanding) machines with capacities from 80 m\u00b3\/h to 250 m\u00b3\/h<\/strong>, effectively serving projects ranging from small civil works to key infrastructure developments. All equipment is directly imported from overseas, genuine products with competitive pricing.<\/p>\n We are committed to delivering the best service, fast and simplified purchasing procedures, and the most competitive prices for sand screening machine trading in Hanoi and nationwide.<\/p>\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 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 This mechanism not only reduces Bentonite material costs but also protects surrounding geological conditions and minimizes construction risks. Modern filtration machines are also equipped with automation features, enabling continuous operation and easy quality control.<\/p>\n Sand screening machines on the market are generally divided into two main types: vibratory screening machines and rotary screening machines. Each type has its own operating principle, advantages, and limitations, suitable for different construction requirements.<\/p>\n Vibratory screens use vibration motors to generate strong oscillations, allowing material to move quickly across the screen surface. As a result, they can process large slurry volumes in a short time, making them suitable for projects with high demands for schedule and screening accuracy. Their compact structure is also an advantage when working in limited spaces or when frequent relocation is required.<\/p>\n In contrast, rotary screens operate based on the rotation of a cylindrical drum screen. Material is fed into the drum and gradually screened during rotation. This type is suitable for coarse materials or mixtures with a high solid content; however, its larger size and slower processing speed make it less suitable for high-capacity projects.<\/p>\nWhat Is a Sand Screening Machine?<\/h3>\n
