1. PAINPOINT DRIVE NOLEING

Are your aggregate production targets consistently derailed by inconsistent feed material from your Lagos quarry site? For commercial quarry operators and exporters, managing the primary crushing stage is a critical bottleneck that directly impacts profitability. Нийтлэг бэрхшээлүүд орно:
Хэт их зогсолт: Frequent blockages and bridging in the primary crusher feed hopper, leading to hours of lost production per week for cleaning and reestablishing flow.
Засвар үйлчилгээний өндөр зардал: Uncontrolled, oversized material entering the primary crusher causes undue stress on components, resulting in premature wear on liners, холбогдол, and shafts.
Тогтворгүй дамжуулалт: Variable feed size from the face leads to a choked or starved crusher, preventing your plant from operating at its designed capacity and efficiency.
Safety and Labor Risks: Manual methods to clear blockages or break oversize rock expose personnel to significant hazard.

How do you ensure a consistent, optimallysized feed to your primary jaw crusher that maximizes uptime, protects your capital equipment, and stabilizes your output for exportgrade aggregate specifications?

2. БҮТЭЭГДЭХҮҮНИЙ ТОЙМ: APG4216 VIBRATING GRIZZLY FEEDER (Vgff vgf)

The APG4216 is a heavyduty Vibrating Grizzly Feeder (Vgff vgf) engineered for the primary separation and feeding of runofquarry material in Lagos's demanding laterite and granite operations. It is the definitive solution for preparing material before the primary crusher.

Үйл ажиллагааны ажлын урсгал:
1. Хүлээн авч байна & Урьдчилсан үзлэг: Dump trucks discharge raw quarry run onto the robust feeder pan. The integral grizzly section (with adjustable openings) allows subfines (жишээ нь e., 100mm) to bypass the crusher, reducing immediate load.
2. Хуваах & Дамжуулах: The vibrating action conveys larger material forward while simultaneously stratifying the load.
3. Controlled Feeding: Oversize rock is smoothly delivered at a regulated rate into the jaw crusher inlet, ensuring it operates within its optimal design parameters without shock loading or starvation.

Хэрэглээний хамрах хүрээ & Хувьсгал:
Саад тохолтол тарз: Ideal for mediumtohigh tonnage quarry primary sections; handles blasted rock, heavy claybound materials, ба нураах бетон. Suited for both fixed plant and semimobile setups common in Lagos export operations.
Хувьсгал: Not designed as a standalone screening plant for precise final product sizing. Maximum lump size is limited by physical deck dimensions; extremely sticky, highmoisture clay without preprocessing can reduce efficiency.

Granite Quarry Primary Crushing Station Upgrade

Challenge A granite quarry supplying aggregates for export concrete piles faced constant jaw crusher overload due to uncontrolled feed from dump trucks, causing tramp iron damage and unplanned stops every two weeks.
Solution Installation of an APG4216 VGF with grizzly set at 120mm was implemented as a buffer between truck tipping and the jaw crusher inlet.
Results The system removed an average of 22% fine waste rock prior to crushing. Crusher overload events were eliminated, liner life increased by 50%, and overall plant throughput rose by a verified 19%.

Laterite Processing Plant Efficiency Improvement

Challenge A laterite processing plant experienced severe blockages in their primary circuit during the rainy season due to sticky clay binding in the feeder hopper.
Solution The APG4216 was selected for its aggressive linear stroke capable of breaking up cohesive materials via vibration energy transfer through the bed depth.
Results Plant managers reported zero complete blockages postinstallation during wet season operations through two cycles.Feed consistency improved,supporting stable operation of downstream washing screens.
