1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Bạn đang quản lý hoạt động sản xuất tổng hợp quy mô vừa và lớn và đang đối mặt với những tắc nghẽn dai dẳng làm xói mòn lợi nhuận? Dành cho người quản lý nhà máy và nhà thầu kỹ thuật, Một 250300 tph stone crushing plant is a critical capital asset, yet standard configurations often introduce costly vulnerabilities.

Regulatory NonCompliance Risk: Sourcing components from multiple vendors creates a compliance gray area. A single noncompliant electrical component or material can halt shipments to regulated markets, resulting in project delays and contractual penalties.
Thông lượng không nhất quán & Hidden Downtime: Promised 300tph capacity often drops under realworld conditions due to feeder mismatches, crusher choke points, or screening inefficiencies. Cái này 1015% deficit translates to thousands of tons of lost production monthly.
Unscheduled Maintenance Spikes: Plants built with offtheshelf, nonintegrated components suffer from uneven wear and premature failures. Unplanned downtime for crusher liner changes or conveyor belt repairs directly impacts your costperton metric.
Cường độ năng lượng & Chi phí hoạt động: Inefficient drive systems and poorly optimized crushing chambers consume excess power. For a plant running 16 hours/day, even a 5% overconsumption leads to a significant annual energy cost burden.

Câu hỏi trung tâm là: how do you achieve guaranteed, compliant throughput without sacrificing operational flexibility or facing unpredictable lifecycle costs?

2. TỔNG QUAN SẢN PHẨM

This product describes a fully integrated, Rohs Compliant 250300tph Stone Crushing Plant. It is a stationary or semimobile crushing and screening circuit engineered as a unified system from primary feed to final product stockpiling.

Quy trình hoạt động:
1. Giảm sơ cấp: Runofquarry material (≤750mm) is fed via a vibrating grizzly feeder to a primary jaw crusher, achieving the first stage of size reduction.
2. Intermediate Crushing & Sàng lọc: Crushed material is conveyed to a secondary cone crusher. The output is then screened; oversize material is recirculated back to the secondary crusher (mạch kín), trong khi vật liệu có kích thước chính xác di chuyển về phía trước.
3. Định hình cấp ba & Định cỡ cuối cùng: For highquality chip and sand production, một tác động trục dọc thứ ba (MỌI NGƯỜI) crusher may be employed for shaping. Final screening decks separate output into precise product fractions (ví dụ., 05mm, 510mm, 1020mm).

Phạm vi ứng dụng: Ideal for producing aggregates for road base, bê tông trộn sẵn, nhựa đường, and railway ballast from limestone, đá granit, đá bazan, and river gravel.
Hạn chế: Not designed for very abrasive metallic ores or sticky, highclay materials without specific configuration modifications.

8.Câu hỏi thường gặp

Q:What defines 'ROHS Compliant' fora complete crushing plant?
MỘT:The Restriction of Hazardous Substances(RoHS) directive restricts specific materialsin electrical/electronic equipment.A fully compliant plant ensures every purchased component—from motorsand PLCsto wiring,cables,and control panels—is certified freeof restricted substanceslike leador mercury.This providesa single,documented chainof custodyfor your entire production line's output.

Q:Canyou integrate an existingcrusherof oursinto this newplant design?
A.We can conductan engineering assessment.Often,the limiting factoris ensuringthe existing unit's electrical componentsandsupplied documentationmeetROHS standards.If it does not,the integration would compromisethe fullplant certification.We typically recommendour matchedcomponentset tomaintain guaranteed performanceand compliance integrity.

Q:Whatisthe expected increasein our operational expenditure(MỞ)?
A.The initial investmentis offsetby measurable OPEX reductions.Field reports indicateenergy savings of15%,lower spare partsinventory costs,and reduced downtime.The central lubrication systemalso lowers labor hoursfor routine maintenance.A detailedTotal Costof Ownership(TCO) modelwill be provided during proposal development.

Q:What happens ifa component failsand needs replacement?Does it void the compliance?
A.No.All recommended spare partsare sourcedfrom the same certified supply chain.Any replacement partwe supply will maintainthe plant's overall compliance status.This is acore benefitofa singlesource solution versusamultivendor assembly.

Q:What site preparationis requiredbefore delivery?
A.We provide comprehensive foundation drawingsanda site preparation checklist.Typical requirementsinclude leveled compacted ground,poured concrete foundationsforspecific modules,and provisionofthe main power supply connection pointat the specified rating.Civil works can oftenbe reducedby25% comparedto traditional plantsdue tour modular design philosophy
