This summary points out how SBM’s VU Tower‑type line, made for diabase, meet the strictest expressway concrete requirement by providing precise 0.075–5 mm sand and super‑fine powder with unbeatable effectiveness ,
Highway and bridge works demand top‑quality fine materials but conventional factories often yields irregular grain spread, too much dust and untrustworthy outputs ; undermining concrete performance and site timetables
The Shaanxi provider identify this shortage and, after checking SBM’s products, choose the VU Tower‑type system to get a steady 70 t/h output of diabase sand and powder made for high‑strength mixtures
Raw diabase (0–15 mm) first enter the C6X Jaw Crusher for initial reduction ; then to the HST Hydraulic Cone Crusher for even mid‑sizing, finally the VU Tower‑shaped Sand‑producing System forms particles through cascade fall technology, improving sphericity and gradation
Integrated PLC‑driven controls watch every unit—Jaw Crusher, Cone Crusher, VU Sand Maker, Vibrating Screen, Belt Conveyor—in real‑time, letting operators adjust parameters at once and keep quality steady
The VU Tower‑shaped Sand‑producing System, special to SBM, combine a Vertical Shaft Impact Rotor with multi‑layer cascade modules so diabase grains are crushed and rounded in one small tower , saving ground space and making layout simple
Supporting tools include the MS Series Steel Platform for strong support, SP Series Vibrating Feeder for regular feed, and SC80 Sand Washer for optional wet cleaning ; offering flexible material handling choices
Unlike water‑heavy competitors, the dry powder extraction unit exactly controls stone‑powder content (<0.075 mm) to meet specific mix designs without wastewater , making it green, cost‑saving and regulation‑ready
SBM designed the whole line as a sealed negative‑pressure system , dust escapes? Never ; pulse‑jet dust collectors catch particulates below 10 mg/m³, noise are dampened by acoustic enclosures, making sure community peace
Zero wastewater release plus no sludge creation means zero eco‑liabilities ; and the line’s energy‑saving drives cut power use by 18% per ton, raising both sustainability and your bottom‑line
Since mid‑2018 start, the 70 t/h plant have kept >95% uptime while making sand with steady fineness modulus ~2.8 and sphericity >85% ; turning into stronger, more workable concrete on site
Clients say 12% faster setting times and lower cement amounts, because of the optimized gradation, plus, steady supply of certified high‑grade sand gets premium market prices, lifting profit margins
Isn’t it time you update your materials chain. SBM’s VU Tower‑type solution stand as the future‑proof pick for highways, high‑speed rail ballast or top architectural concretes !
