Standardized Design Of Artificial Sand Production Line

Artificial sand is one of the main raw materials for concrete, mortar and corresponding products. Traditional sand and stone production lines are generally small in scale, lacking long-term planning and design, and can no longer meet the needs of current development. Therefore, a new type of artificial sand production line came into being, and standardized design is imperative.

The design of the gravel production line involves mines, general plans, processes, electrical automation, civil engineering, water supply and drainage, HVAC, environmental protection, budget estimates, and technical economy.

1. Determine a reasonable rough location

Based on the quality of the existing mines or newly purchased mines, the planned mining period is estimated to be 15 to 20 years. Consideration should also be given to placing the sand and gravel plant near the quarry in order to reduce the transport distance of raw materials. When the quarry and the main user are far away, rough crushing should be arranged in the quarry, and the intermediate material after the rough crushing is sent to the main plant area through the conveying equipment to continue processing and manufacturing. selection

  • (1) The site of the plant must avoid the danger zone of blasting. The safety distance should meet the requirements of relevant regulations, and the distance from the blasting point should exceed 200m.
  • (2) The site should be close to the existing transportation roads, water sources, and power sources.
  • (3) The plant site should be far from the town or residential area. When it must be located in the town or residential area, it should be arranged on the downwind side of the dominant wind direction and maintain the necessary protective distance.

3. total graphic design

  • (1) Satisfy relevant specifications or regulations of technology, transportation, fire prevention and construction.
  • (2) On the premise of meeting the technical requirements, the overall plane layout should be as compact as possible to save land, while leaving room for equipment operation and maintenance.
  • (3) Make full use of the existing terrain for vertical design to reduce the amount of earthwork, so that the crushed material can flow by itself or semi-automatically.
  • (4) The rough breaking position should be close to the incoming direction of the material yard, and the finished material yard should be close to the transportation road.
  • (5) Avoid disposing of important workshops such as crushing, sieving and sand making in karst caves, landslides, debris flows and filling areas. If it is necessary to arrange in the above-mentioned areas, full technical justification should be adopted and reliable measures should be taken.

4. electrical automation

The electrical automation design should adopt advanced and reliable DCS or PLC control system, with a high level of automation, in order to achieve the goals of high efficiency, energy saving, stable production, optimized control, etc., and minimize the number of operating posts and reduce production costs.

5. building structure

Under the premise of meeting the production requirements, the civil engineering design should be arranged in the open air as much as possible to minimize the cost of civil engineering. Architectural design should strictly abide by the current relevant national building design codes and standards, pay attention to ventilation, heat dissipation, sound insulation, and shock absorption measures in the workshop, and adopt technical measures such as fire prevention, explosion protection, waterproof, and moisture resistance.

6. Water supply and drainage and HVAC

  • (1) The water used in the aggregate production line is mainly considered in terms of spray dust removal water, sand and stone washing water, domestic water, fire water and other aspects. The drainage system adopts the drainage system of rainwater and production and domestic wastewater.
  • (2) In the heating zone stipulated by the state, the design should consider centralized heating; the workshops that emit waste heat during the production process, the pits that transport cold and hot materials, the wet and hot pits such as underground belt corridors, the chlorine chambers of circulating water pumping stations, Sewage pumping stations, air compressor stations, etc. should be designed to ventilate in order to eliminate residual heat and harmful gases; accidental fan switches are set at indoor and outdoor locations that are easy to operate.
  • (3) Calculate the total air consumption of the production line based on the dust collector and other compressed air points of the production line, and take into account the pipeline leakage, the regeneration air consumption of the suction dryer, and the safety factors of 1.2 to 1.3. Design and select the compressed air station of the production line. Total design capabilities.

7. Mining

In the field of mining, by analyzing mine exploration data, formulating mine development and utilization plans, rational use of mine resources, consideration of recultivation and forestry, avoiding adverse geological disasters, development and utilization, protection of ecology, resource conservation, and environmental friendliness.

8. production process

Process design must first determine the production scale, perform process balance calculations, reasonably determine process equipment capabilities, operating rates, perform material balance calculations, and reasonably determine the storage methods and storage periods for various materials.

According to the characteristics of dust in the production process, determine the dust removal program, calculate the air volume, and choose a dust collector reasonably.

Analyze the soil content, hardness, and other characteristics of the ore. Based on the characteristics of the company’s region, and through the comparison of the plans, reasonably select equipment such as soil removal, crushing, screening, sand making, dust removal, and transportation.

The process design balances the power, water and gas consumption of the entire plant, and uses system theory to optimize the performance of each link of the artificial sand and gravel production line, and the entire production line runs with high quality and efficiency.
