As the country attaches importance to the sand and gravel industry, many investors are eager to try and invest in sand production lines. For those who do not know how to do it, where do you start the sand and gravel production line? How to configure? What are the skills? Professional matters are left to professional people. The EPC project general contracting mainly includes three aspects: scheme design, technical assistance and support for project infrastructure, supply, installation and commissioning.
1. Scheme design
(1) Production line design is really impossible for someone who has not been in this industry before. Especially now that the environmental protection is high pressure, an environmentally friendly, fully enclosed, dust-free, and noise-free production line is very important, and this is guaranteed in the EPC turnkey project.
(2) Staffing is also directly related to the design of the above production line. A good production line does not require a lot of manpower, and only a few people are required to control it.
(3) Site planning, site planning in the early stage of road paving, and road paving have a direct impact on the operation of the later sand and gravel plant. If the site planning is close to the original mine, it can save a lot of material and manpower for transportation.
(4) The intelligent electronic control unit system of plant office facilities, water and electricity heating system can save a lot of investment costs such as manpower and material resources. In addition, common office systems, water and electricity heating systems are also necessary facilities.
(5) Environmental protection facilities are also very important. The use of certain environmental protection facilities directly affects environmental protection indicators. We all know that certain parameters must not exceed specific values during the environmental assessment procedures. Appropriate and reasonable environmental protection facilities the passage of EIA procedures is closely related.
2. Technical assistance and support for project infrastructure
(1) The construction of steel structure workshops, the construction of production line equipment infrastructure, and the production line equipment infrastructure are all within the EPC project general contract. Before installing the entire production line, some basic work is required to complete the installation of the entire production line.
(2) Sewage treatment, dust removal system construction, etc. We all know the current status of environmental protection policies, and it is imperative to adopt some environmental protection measures such as sewage treatment and dust removal systems.
3. Supply, installation and debugging
Not only can we provide the main equipment crusher, sand making machine, etc., the procurement of other supporting equipment used in the entire production line is also included in the EPC general contract, such as conveyor belts, dust removal facilities, etc.
50t/h high-quality sand production line for dry-mixed mortar station
Project introduction: The system is mainly used to produce fine sand for ready-mixed mortar. The designed output is 50t/h, the raw material is crushed stone below -30mm, the fineness modulus of the finished sand can be adjusted between 2.4-3.0, and the content of stone powder is controlled within 5%-15%, the core host equipment of the system configuration is a PLS1000 special sand making machine produced by Luoyang Dahua. The finished product has good grain shape, stable grain size, low equipment cost, and simple maintenance. Other supporting hosts include multi-layer fine particle screening machine, high-efficiency powder separator, environmental dust removal equipment, bucket elevators, powder tank and other related measuring and conveying equipment. This system can not only produce sand with rounded grains, but also adjust and control the distribution of sand grains through the efficient operation of grading screens, powder separators and dust removal equipment, ensuring continuous and stable grading of finished products, and satisfying customers for dry-mixed mortars. The production indicators are required to achieve a dust-free and clean production environment. This high-quality sand making production line adopts a plane layout, has a small area, and is fully integrated with the supporting dry-mix mortar station to form a two-digit integrated solution. The production line has simple and smooth technology, efficient and economical operation, energy saving and environmental protection.
