Feldspar Raw Material Grinding Production Line Built For Local Ceramic Manufacturing Enterprise In Ghana
Ghana holds abundant feldspar mineral deposits in inland mountainous zones, and local ceramic tile, daily ceramic and glass processing factories are expanding production scale year by year. Feldspar powder is the core inorganic raw material for ceramic body, glaze and glass melting, yet local mineral processing equipment was backward before cooperation, most factories imported finished feldspar powder from overseas with very high transportation cost and unstable supply cycle. To realize local self-supply of ceramic raw materials and reduce overall production cost, the client cooperated with us to build a full-process feldspar grinding station equipped with MTW European trapezium mill.
Our technical team collected local feldspar ore samples and carried out hardness, fusibility and fineness matching tests. We selected upgraded MTW European trapezium mill as core grinding equipment, which features reinforced grinding roller assembly and optimized air flow classification structure. Instead of long-term full-load 26t/h operation, we calibrated daily stable output at 15 tons per hour. Gentle and balanced load operation effectively reduces abrasion of grinding rollers, ring liner and blade parts, extending spare parts replacement cycle and cutting annual factory maintenance expenditure.
The factory adopts dual-shift working mode widely used by local medium-sized processing plants. Two separate 8-hour production shifts run every working day, with one hour reserved for equipment residue cleaning, lubrication and full safety inspection. Under steady 15t/h continuous production state, around 240 tons of high whiteness qualified feldspar fine powder can be produced each day. Powder fineness can be flexibly adjusted between 120 mesh and 600 mesh to meet different fineness standards required by ceramic glaze, glass raw material and refractory material manufacturers.
Workshop Layout Design And Complete Equipment Supporting Profile
The whole feldspar grinding line adopts compact horizontal layered layout, matching independent raw ore feeding silo and sealed finished powder storage silo to realize automatic enclosed production without manual material transfer. All core grinding host, conveying pipelines, sealing accessories, pulse dust removal unit and touch screen PLC control system are delivered as one complete full set, so the client does not need to source any separate auxiliary matching parts locally. Two senior field technical engineers from our team traveled to the project site to supervise equipment hoisting, pipeline docking and full-line stable commissioning, and the whole grinding line reached formal profitable production within 21 days after all cargo arrived at the port.
A full closed-loop processing workflow covers raw feldspar feeding, MTW European trapezium fine grinding, powder air classification, pulse bag dust collection and sealed finished powder storage, forming an uninterrupted production chain without processing dead zones. Detailed equipment configuration and practical running indicators are listed below:
Core Grinding Equipment: Upgraded heavy-duty MTW European trapezium mill with thickened wear-resistant grinding roller assemblies
Stable Hourly Production Capacity: 15 tons/hour, adjustable range 8–26t/h, varies with feldspar ore hardness and target powder mesh number
Daily Output Of Qualified High-Whiteness Feldspar Fine Powder: Around 240 tons, 16 hours of effective production under two shifts
Adjustable Finished Powder Mesh Range: 120–600 mesh, real-time online adjustment without shutting down the entire grinding line
Maximum Permitted Feed Particle Size: Feldspar raw stone ≤32mm after primary jaw crushing treatment
Production Operation Mode: Fully sealed negative pressure circulating grinding, near-zero dust leakage inside the whole steel workshop space
Full Supporting Equipment: Raw feldspar storage silo, constant quantitative vibrating feeder, MTW European trapezium mill, high efficiency air powder classifier, large area pulse bag dust collector, centrifugal induced draft fan, PLC touch screen intelligent control cabinet, sealed finished feldspar powder silos, safety maintenance steel platform
Core Practical Advantages Of This Ceramic Raw Material Specialized Grinding Scheme
Optimized Load Matching Extends Service Life Of Vulnerable Wear Parts
Feldspar ore contains tiny hard mineral impurities, which will cause continuous abrasion to grinding roller and ring liner during long-term grinding. For overseas ceramic raw material processing plants, frequent replacement of wear parts generates heavy international shipping cost and long-time production halt losses. By limiting daily stable output to 15t/h instead of continuous full-load overload operation, we effectively reduce the abrasion rate of all key vulnerable components. The replacement cycle of core wear-resistant spare parts can be extended by nearly 30%, avoiding unexpected production suspension triggered by mechanical aging and overload damage.
Full Set Integrated Shipment Eliminates Local Parts Matching Trouble
All conveying pipelines, connecting flanges, sealing gaskets, driving motors and auxiliary machinery are pre-assembled and fully tested inside our factory before shipment, with unified standard connecting ports. Local construction crews can complete equipment docking directly without extra cutting, welding or on-site modification work, greatly compressing overall construction cycle and enabling the client to launch formal feldspar powder supply to local ceramic factories faster.
Matched Large Bag Dust Removal System Meets Local Industrial Emission Supervision Rules
Ghana enforces strict regulatory standards for industrial dust emissions in mineral processing workshops. We upgraded the matched large pulse bag dust collector to fully match the air volume demand of MTW European trapezium mill unit, enabling the entire grinding line to operate under fully enclosed negative pressure circulation. Almost no floating dust can be observed during normal production, and the project smoothly passed local environmental compliance inspection on the first post-commissioning audit.
Simplified Touch Screen Central Control Lowers Operator Training Threshold
The matched PLC control cabinet adopts streamlined intuitive touch operation panel, which clearly displays real-time running data including raw feldspar feeding speed, finished powder fineness, main motor load and equipment operating current. We provided three full days of hands-on on-site operation training for the client’s on-site operators; ordinary factory staff can independently monitor and regulate the whole MTW European trapezium mill grinding line without advanced professional industrial technical background.
Main Application Fields Of Produced High-Whiteness Feldspar Fine Powder
The high whiteness feldspar powder manufactured by this grinding line is supplied to dozens of downstream ceramic, glass and refractory material manufacturers distributed across Ghana, covering multiple core industrial application sectors:
Low-temperature flux raw material for ceramic tile body and daily ceramic glaze production
Aluminum-containing filling raw material for soda-lime glass and architectural glass melting processing
High temperature resistant mineral raw material for industrial refractory brick and casting coating manufacturing
Lightweight inorganic filler for exterior wall coating and waterproof mortar production
Global Turnkey Service Support For Mineral Grinding Line Projects
We have delivered dozens of MTW European trapezium mill full grinding line cooperation projects to various regions across the globe, accumulating abundant practical experience to adjust production line supporting schemes according to local climate conditions, environmental protection policies and daily factory production operation customs.
For every overseas mineral processing project, we complete full pre-assembly and no-load aging testing inside our factory before shipment to guarantee perfect matching of all main equipment and spare parts. Professional overseas technical engineers can be dispatched to provide full-cycle on-site installation guidance and operator hands-on training services. Original factory wear-resistant spare parts for MTW European trapezium mills are supplied all year round at factory direct prices, with flexible global sea freight logistics solutions to shorten spare parts delivery waiting period.
