Chinese Sand Gravel Mining Contract Manufacturer
1. PAINPOINT DRIVE NOLEING
Үйл ажиллагааны зардал нэмэгдэж, урьдчилан таамаглах аргагүй зогсолт нь таны элс, хайрганы захыг сүйрүүлж байна? Managing a modern aggregate operation presents distinct challenges that standard equipment often fails to address. Эдгээр нийтлэг зүйлийг авч үзье, өртөг өндөртэй хувилбарууд:
Өндөр элэгдэл & Засвар үйлчилгээний зардал: Abrasive silica and gravel rapidly degrade standard components, байнга болоход хүргэдэг, unscheduled shutdowns for liner changes, pump rebuilds, and conveyor belt replacements.
Эцсийн бүтээгдэхүүний чанарт нийцэхгүй: Fluctuations in feed material cause offspec product—fines content too high or particle distribution out of grade—resulting in rejected loads and lost revenue.
Inefficient Water & Sludge Management: Ineffective washing and clarification systems waste process water, create environmental compliance hurdles, and lose valuable fines to settling ponds.
Үйлдвэрийн ерөнхий үр ашиг бага: Bottlenecks at crushing, Дэлгэц авах, or material handling stages limit total throughput, preventing you from capitalizing on highdemand periods.
What if your key processing equipment was engineered from the ground up to confront these specific abrasion, ангилал, and reliability challenges? The solution lies in partnering with a specialized contract manufacturer for your core sand gravel mining equipment.
2. БҮТЭЭГДЭХҮҮНИЙ ТОЙМ
This content details a comprehensive line of stationary and modular sand washing, ангилал, and dewatering equipment manufactured under contract for sand and gravel mining operations. As your contract manufacturer, we engineer and build the core machinery that transforms raw feed into specification aggregate.
Үйл ажиллагааны ажлын урсгал:
1. Тэжээл & Хувиарилалт: Crushed material is evenly distributed into the washing system.
2. Шат байдал нөлөөлөх & Чөлөөлөлт: Rotating paddles or screws scrub particles to break down clay clots and liberate fines from coarse aggregate.
3. Гидравликийн ангилал: Precise water flow rates separate particles by size and specific gravity in settling tanks or hydrocyclones.
4. Mechanical Dewatering: Screws or vibratory decks remove excess water from fine and coarse products to meet shipping moisture specifications.
5. Торгуулийн нөхөн сэргээлт & Усны менежмент: Integrated cyclones and thickeners capture ultrafine particles for byproduct sale while clarifying water for recirculation.
Хэрэглээний хамрах хүрээ: Ideal for virgin aggregate processing, crushed stone rewashing, and construction/demolition material recycling. Primary limitations include maximum feed size (typically ≤1”) and the requirement for a consistent water supply; dry processing solutions are configured separately.
