First, the process plant configuration type

The process plant is generally divided into three types of layout: multi-layer arrangement; single-layer arrangement; hybrid arrangement.

1. The advantage of multi-layer layout is that the factory has a small footprint, which is conducive to material flow. The disadvantage is that the building structure is complicated and the drop between the units is generally large. 98 fused magnesia is mostly used in the process of high material gravity gradient and less return products in the process. Such as the three-stage open road crushing plant, re-election plant, coal washing plant.

2. The disadvantage of single-layer layout is that the plant has a large area and is relatively scattered in management, but the structure of the plant is relatively simple, and it is convenient to install large-scale and vibration equipment. It is mostly used in various types of concentrating plants with small material conveying slope, large return operations and large return volume.

3. Hybrid layout is also the layout that is often used in actual design. According to the requirements of the process and equipment, the focus is different, and it needs to be determined by the technical and economic comparison of multiple schemes.

Second, the basic principles and points of equipment configuration

Basic principles of device configuration:

1. The quipment configuration should fully reflect the process requirements, have sufficient adaptability to the fluctuation of ore properties, and should have the possibility of reforming the process and expanding the scale. There is some flexibility in the auxiliary facilities depending on actual needs and possible room and height difference.

2. The production system should be reduced as much as possible to reduce the complexity of drug delivery, water supply and power supply.

3, the distance between the equipment units should not be too large, according to the requirements of production operations and maintenance, taking into account the relationship between the modulus of the civil column network to determine. The same type of equipment should be concentrated as much as possible, and a segmented centralized type can be used if necessary. Such as coarse grinding and re-grinding, rough selection and selection work are separately configured.

4. Make full use of the self-flow and choose a reasonable self-flow slope and gravity flow system. The calculation should be carried out on the large-scale, long-distance and critical flow troughs, trenches and pipelines. Due to the large fluctuations in the particle size, flow rate, concentration and density of the flowing materials in the pipelines, troughs and trenches in the plant, the selection of the gravity gradient should be adequately adapted and should not be too small. Production data is selected. Self-flow systems are designed to be adaptable and flexible.

5. The maintenance site shall be decided with similar enterprises in accordance with the provisions of this manual, and small maintenance equipment and power supply and water supply facilities shall be provided.

6, plant and equipment configuration must fully consider the environmental protection, safety, labor insurance regulations. In the equipment safety cover, safety railings, anti-virus, fire prevention, ventilation, dust collection, sewage, etc., should meet the standards.

7. The electronic computer control room should select the appropriate location and building standards according to the manufacturer's product specification.

8. The public, cultural and welfare facilities of the mineral processing plant should be considered in a coordinated manner. Make full use of the spare space of the production plant.
