Sand Gravel Mining Dealers Procurement
1. PAINPOINT driven اوپننگ
Managing a sand and gravel operation means contending with persistent, قيمتي غير موثريت. ڇا توهان انهن عام چئلينج کي منهن ڏئي رهيا آهيو?
غير منصوبا بند وقت: Frequent mechanical failures in material handling and processing equipment halt your entire production line, گم ٿيل آمدني ۽ بيڪار محنت ۾ هزارين في ڪلاڪ خرچ.
متضاد فيڊ & پيداوار جي معيار: Fluctuations in feed size and moisture content from the pit lead to process instability, resulting in offspec product, وڌايل فضول, ۽ رد ٿيل لوڊ.
اعلي سار سنڀال & ڪپڙا خرچ: The abrasive nature of aggregate rapidly degrades components like pump impellers, اسڪرين ڊيڪ, and classifier wear shoes, driving up your parts inventory and maintenance labor expenses.
غير موثر پاڻي & فائنس مينيجمينٽ: Inadequate separation of fines consumes excessive process water, complicates settling pond management, and represents a direct loss of saleable material.
LaborIntensive Oversight: Reliance on manual adjustments and monitoring for crushers, اسڪرين, and classifiers leads to operator fatigue, inconsistent settings, and delayed response to process upsets.
The central question for procurement specialists and plant managers is this: how can you specify equipment that directly mitigates these issues to improve your cost per ton?
2. پيداوار جو جائزو: HIGHCAPACITY HYDROCYCLONE CLASSIFIER
For sand and gravel mining dealers seeking precise control over material classification, a highcapacity hydrocyclone system is a critical component. This equipment separates particles by size in a slurry using centrifugal force, specifically designed for the rigorous demands of aggregate processing.
آپريشنل ڪم فلو:
1. ڍڳا انٽ: The sandwater slurry is pumped under pressure tangentially into the cyclone’s upper chamber.
2. سينٽرفيوگل علحدگي: Rapid rotation creates a vortex; coarser, heavier sand particles are forced to the walls and descend.
3. Dual Discharge: Classified sand discharges as a thickened underflow from the apex (هيٺيون), while fine particles (silt/clay) and water exit via the overflow pipe (top).
4. پروسيس انضمام: The underflow reports to dewatering screens or stockpiles; the overflow is directed to settling ponds or recirculation systems.
ايپليڪيشن جو دائرو: Ideal for washing, درجه بندي ڪرڻ, and dewatering crushed stone, سانت, ۽ پٿر. Effective for removing fines (عام طور تي 200 ميش) to meet ASTM C33 or other specifications.
اهم حدون: Requires a consistent feed pump pressure for optimal performance. Not a drying solution; output is a damp solid. Primary separation is based on particle size and specific gravity; shape can be a minor factor.
