Custom Vertical Grinding Production Line For Local Mineral Processor In Saudi Arabia
This full vertical roller mill processing system is a full turnkey project we delivered to a large mineral manufacturing enterprise operating in Saudi Arabia. The region holds massive reserves of limestone and calcite raw ore, and the continuous expansion of local cement plants, municipal infrastructure and thermal power stations creates stable long-term demand for qualified industrial mineral powder. The client previously imported finished mineral powder from overseas with extremely high comprehensive cost, so they planned to build an independent full-process grinding station on their quarry land to cut raw material supply expenditure and expand local supply coverage.
After sending raw ore samples to our factory for hardness, abrasion and grindability testing, we matched large vertical roller mill as core processing equipment. Instead of pushing the unit to its maximum 45 tons per hour limit, we calibrated the daily stable running capacity at 25 tons per hour. Operating under moderate load effectively slows down abrasion of grinding rollers, grinding table and lining plates, greatly reducing the frequency of overseas spare parts procurement and cutting annual factory maintenance costs significantly.
The factory adopts dual-shift operation mode widely used by local large industrial enterprises. Two 8-hour production shifts run each working day, with one hour reserved for equipment cooling, inner cavity cleaning and full safety inspection. Under steady 25t/h production condition, roughly 400 tons of standard mineral fine powder can be produced every single day. Powder fineness can be adjusted freely between 80 mesh and 400 mesh to satisfy diversified specification standards of cement factories, power plants and construction material manufacturers.
On-Site Station Layout And Full Set Equipment Matching Details
The whole grinding station adopts integrated multi-layer steel frame layout, matching independent raw material feeding silo and finished powder storage silo to realize fully automatic closed-loop production without manual transfer links. All main equipment, conveying pipelines, sealing fittings, dust removal unit and electrical control system are delivered as one complete package, so the client does not need to source any auxiliary matching parts separately on site. Three experienced senior technical engineers from our team traveled to the project site to supervise equipment hoisting, frame assembly, pipeline connection and full-line commissioning, and the whole station reached stable normal production within 28 days after all goods arrived at the port.
The closed-loop processing flow covers raw ore feeding, vertical roller grinding, powder classification, pulse dust collection, finished powder storage, forming an uninterrupted production chain without dead angles. Complete equipment configuration and actual operation indicators are listed below:
Core Grinding Equipment: Large industrial vertical roller mill with three groups of grinding roller assemblies
Stable Hourly Production Output: 25 tons/hour, adjustable range 15–45t/h, fluctuates with raw ore hardness and target powder mesh
Daily Output Of Qualified Mineral Fine Powder: Around 400 tons, 16 hours of effective production under two shifts
Adjustable Finished Powder Mesh Range: 80–400 mesh, online adjustment without stopping the whole grinding station
Maximum Allowed Feed Particle Size: Limestone/calcite raw blocks ≤40mm after primary crushing
Production Running Mode: Fully sealed negative pressure circulating grinding, ultra-low dust overflow inside the whole workshop
Complete Supporting Equipment: Raw material silo, quantitative belt feeder, large vertical roller mill, high efficiency powder classifier, large-area pulse bag dust collector, centrifugal induced draft fan, PLC centralized intelligent control cabinet, finished powder storage silos, multi-layer steel operation platform
Distinctive Strengths Of This Vertical Mill Processing Scheme
Reasonable Load Calibration Extends Service Cycle Of Core Wear Parts
For large overseas mineral processing stations, frequent replacement of vertical mill rollers, table liners and other heavy wear components will bring tremendous international logistics cost and long-time production shutdown losses. By limiting regular stable output at 25t/h instead of full-capacity overload operation, we effectively slow down the wear speed of all core vulnerable components. The replacement cycle of key wear-resistant parts can be extended by nearly 40%, avoiding unexpected production suspension caused by mechanical aging and overload damage.
Integrated Full Package Shipment Simplifies On-Site Construction Work
All steel frame components, conveying pipelines, connecting flanges, sealing gaskets, driving motors and auxiliary machinery are pre-assembled and tested inside our factory before delivery, with unified standard connecting interfaces. Local construction crews can complete frame assembly and equipment docking directly without extra cutting, welding or on-site modification work, greatly shortening the overall construction cycle and helping the client realize profitable production much faster.
Matched Large Bag Dust Collector Complies With Local Industrial Emission Standards
Saudi Arabia implements strict control standards for industrial dust and waste gas emissions. We upgraded the matched large pulse bag dust collector to fully match the air volume demand of the large vertical roller mill unit, enabling the whole grinding station to operate under fully enclosed negative pressure state. Hardly any floating dust can be observed during normal production, and the project smoothly passed local environmental compliance inspection on the first check after full commissioning.
Simplified Central Intelligent Control Reduces Operator Training Cost
The matched PLC control cabinet adopts streamlined intuitive touch operation panel, which can display real-time data including raw material feeding speed, finished powder fineness, main motor load and equipment operating current clearly. We delivered four days of hands-on on-site training for the client’s on-site operators; ordinary factory staff can independently operate and monitor the whole vertical mill station without advanced professional industrial technical knowledge background.
Main Downstream Application Directions Of Produced Mineral Fine Powder
The industrial mineral powder manufactured by this grinding station is supplied to dozens of manufacturing enterprises distributed across multiple provinces of Saudi Arabia, covering multiple high-demand industrial sectors:
Core raw material filler for Portland cement, cement clinker and precast concrete component production
Flue gas desulfurization absorbent for local large-scale coal-fired thermal power plants
Base raw material for highway, municipal road and large-scale civil construction projects
Inorganic filling additive for water-based architectural coatings, rubber and plastic deep processing industry
