Sand Aggregate IndustryComprehensive Service ProviderSand Aggregate IndustryComprehensive Service ProviderRaw Material Feeding and Primary Crushing：Raw materials are uniformly fed into the jaw crusher (A2) by the vibrating feeder (A1) for primary crushing.
- The crushed materials are conveyed to the intermediate bin (A3) for temporary storage by a belt conveyor.
Secondary Crushing：Semi-finished materials are fed into the cone crusher (A4) by a belt conveyor for secondary crushing, so as to meet the particle size required for sand making.
Screening：The crushed materials enter the vibrating screen (A5) for pre-screening.
- Oversized materials on the screen are returned to the cone crusher (A4) for re-crushing via belt conveyor (B1).
- Qualified undersize materials are sent to the intermediate bin (A6) for temporary storage.
Sand Making：Materials from the semi-finished bin are fed into the sand making machine (A7) by the intermediate bin feeder (A6) via a belt conveyor.
Finished Product Screening and Washing：Materials after sand making enter the vibrating screen (A8) for classification to separate the finished sand.
- Oversized materials are divided into two streams:
one is conveyed back to the intermediate bin (A6),
the other is sent to the sand making machine (A7) for re-crushing via belt conveyor (B2).
- The finished sand enters the sand washer (A9) for cleaning and is then conveyed to the finished product stockpile.
- Waste sand and slurry discharged from the sand washer are sent to the dehydration screen (A10) for recovery, so as to reduce material waste.
Pre‑cleaning：Suitable for raw materials with high mud and impurity content, allowing pre‑screening and classification.
Complete Process：Adopts a full process flow: primary crushing – secondary crushing – pre‑screening – sand making – screening & washing, enabling direct production of high‑quality manufactured sand that meets engineering gradation requirements.
Excellent Particle Shape：With the combination of cone crusher and sand making machine, the finished product features rounded grains, low flaky particle content, complying with high‑quality building material standards.
Eco‑friendly & Energy Saving：Equipped with sand washer and fine sand recovery unit, it effectively recovers fine sand, reduces discharge, and minimizes environmental impact from dust and wastewater.
Flexible Adaptation：Designed with a capacity of 50–60 t/h, it is ideal for small and medium‑sized sand and aggregate projects or as a supporting sand‑making unit for large production lines. It has a compact layout and controllable investment.
The aggregates production line of Huaibei totally meets Anhui actual situation of huge limestone resources. The heavy hammer crusher is adopted to take place traditional jaw crusher and impact crusher.
EPC general contract construction, the first construction is 1500t/h limestone production line, the second cooperation to build a new 3000t/h limestone processing line.
We find stone firstly have first-stage crushing and then fine crushing to get the fine finished materials. It expressed the principle of harmonious coexistence with environment with clean production environment and less pollution.
The use of Zhongyu Dingli EPCO general contracting, more worry, Zhongyu Dingli has a full set of sand and stone processing equipment, as well as design institute design production line, mapping, civil engineering, installation, operation, after-sales and so on are very professional.
Based on the customer's site conditions, production capacity requirements and raw material characteristics, we will provide layout design for the production line, equipment selection and process optimization solutions.
The professional technical team offers systematic training on equipment debugging, production line operation, daily maintenance, repair and troubleshooting.
The equipment has obtained ISO9001 and EU CE certifications, has received over 200 patents, offers a one-year warranty period and subsequent lifetime technical guidance, including spare parts supply and emergency fault response.
