flow chart of the production process in a river stone crushing plant

A flow chart of the production process in a river stone crushing plant is shown in Figure 6.1. The process starts with the primary crushing of river stones up to 50 cm in size. The material is then transferred to the secondary crushing stage, where it is crushed to smaller pieces (5-10 cm). The material is then transported to the tertiary crushing stage, where it is crushed to even smaller pieces (2-5 cm). Finally, the material is transported to the screening and washing stage, where it is cleaned and sorted according to size and type.

The river stone crushing plant flow chart

The river stone crushing plant flow chart begins with the vibrating feeder and it will evenly enter into the jaw crusher for primary crushing. After being crushed in the jaw crusher, the material will be delivered to the impact crusher for further crushing. Then, it will be returned to the vibrating screen for final separation.

The different types of crushers

In a river stone crushing plant, there are several types of crushers that can be used to crush the raw materials. The different types of crushers include:

1. Jaw Crusher: A jaw crusher is typically used for primary crushing purposes. It uses compressive force to crush the raw materials between its two jaws.

2. Cone Crusher: A cone crusher is similar to a jaw crusher, but it uses a different mechanism to crush the raw materials. Instead of using compressive force, it uses a rotating cone to break the material down.

3. Impact Crusher: An impact crusher is also similar to a jaw crusher, but it uses an entirely different crushing mechanism. Instead of using compressive force, it uses high speed collisions to break the material down.

4. Roller Crusher: A roller crusher is another type of crusher that can be used in a river stone crushing plant. This type of crusher uses two rollers that crush the raw materials against each other.

The different types of screens

There are several types of screens that can be used in a river stone crushing plant. The most common type is the vibrating screen, which is used to separate the stones by size. The other types of screens include rotary screens and roller screens.

The different types of conveyors

There are many different types of conveyors, each with its own unique set of benefits and drawbacks. Here is a brief overview of some of the most common types:

1. Belt Conveyor: Belt conveyors are the most commonly used type of conveyor. They consist of two or more pulleys that rotate around a continuous loop of material (the belt). The material is moved forward by the friction between the belt and the pulleys.

2. Roller Conveyor: Roller conveyors use a series of rollers to move items along a path. They are often used in conjunction with other types of conveyors, such as belt conveyors, to create an efficient production line.

3. Chain Conveyor: Chain conveyors consist of a series of interconnected chains that move items along a path. They are often used for heavy-duty applications, such as moving car parts or large containers.

4. Slat Conveyor: Slat conveyors also use a series of rollers, but they have slats (usually made from wood or metal) attached to them instead of a belt. The slats provide support for the item being conveyed and help keep it from falling off the roller.

5. Gravity Conveyor: Gravity conveyors rely on gravity to move items along a path. They can be used for either light-duty or heavy-duty applications, depending on the weight of the item being conveyed and the incline of the conveyor.

6. Flexible Conveyor: Flexible conveyors are similar to roller conveyors, but they have a flexible belt instead of rollers. This allows them to be used in tight spaces or around curves.

7. Overhead Conveyor: Overhead conveyors suspend items from an overhead track, making them ideal for moving heavy or awkwardly shaped items.

The production process of the river stone crushing plant

The river stone crushing plant is a process flow chart of the production process. The first step is to extract the raw materials from theriver bed. The extracted raw materials are then transported to the crushing plant where they are crushed and screened. The crushed and screened materials are then transported to the third step, which is to classification.

The classification process separates the crushed and screened materials into two categories: usable material and unusable material. The unusable material is then transported to the fourth and final step, which is disposal.

The equipment used in the river stone crushing plant

In a river stone crushing plant, the equipment used can vary depending on the size and type of the stone. For example, if the stone is relatively soft, such as limestone, the equipment may include a jaw crusher, impact crusher, vibrating screen and belt conveyor. If the stone is harder, such as granite or basalt, then the equipment may include a gyratory crusher, cone crusher and vibrating screen.

The process begins with preliminary screening of the stone to remove any impurities. The stone is then fed into the jaw crusher for primary crushing. The crushed stone is then passed through a secondary crusher (cone or impact), where it is further reduced in size. The screened and crushed stone is then conveyed to a third stage (vibrating screen) where any final impurities are removed before being fed into an aggregate wash plant for final cleaning and sorting.

Conclusion

The production process in a river stone crushing plant can be divided into several stages, each of which requires different types of equipment and expertise. By understanding the individual steps in the process, you can ensure that your river stone crushing plant runs smoothly and efficiently from start to finish.
