The selection of equipment for a 500-ton-per-hour sand and gravel aggregate production line requires a comprehensive consideration of many factors. The following is a detailed introduction:

 

Understand the characteristics of raw materials

Hardness: If the raw material hardness is high, such as granite, basalt, etc., a jaw crusher can be used for coarse crushing, and a cone crusher can be used for medium and fine crushing; if the raw material hardness is low, such as limestone, bluestone, etc., in addition to the jaw crusher for coarse crushing, the impact crusher can be used for medium and fine crushing. It can effectively handle materials of medium hardness and below, and the finished product has a better particle shape.

 

Particle size: When the raw material particle size is large, it is necessary to equip the coarse crushing equipment with a larger feed inlet size, such as a large jaw crusher; the raw material particle size is relatively small, and the coarse crushing equipment can be selected with a slightly smaller specification, but it must also ensure that it can meet the production capacity requirements.

 

Water content: If the raw material has a high water content, the anti-blocking and moisture-proof performance of the equipment needs to be considered. For example, equipment with a pre-screening function can be selected to first screen out impurities such as soil with high water content to prevent blockage problems in the subsequent crushing process.

Determine product requirements

Finished product size: clarify the specific particle size specifications of the required sand and gravel aggregates, such as the product ratios of different particle size ranges such as 0-5mm, 5-10mm, 10-20mm, etc. Select appropriate screening equipment according to the finished product particle size requirements, such as the mesh aperture and number of layers of the vibrating screen should match the finished product particle size.

 

Product quality: For sand and gravel aggregates with high quality requirements, such as projects with strict requirements on particle shape and gradation, crushers with shaping functions can be given priority in the selection of crushing equipment, such as impact crushers (sand making machines), which can make the finished product particle shape more regular and the gradation more reasonable.

 

Plan site layout

Production line area: Reasonably plan the equipment layout according to the actual site size, and try to choose a compact and small-footprint equipment combination. For example, some new crushing equipment pays more attention to space utilization efficiency in design, and can achieve efficient production in a limited site.

 

Connection between equipment: The connection between equipment should be smooth, reducing the transfer links and drop in the material transportation process, and reducing energy consumption and wear in the material transportation process. Appropriate conveying equipment, such as belt conveyors, can be used. Its conveying capacity should match the production capacity of the production line, and the conveying angle and length should meet the site layout requirements.

 

Consider equipment performance

Production capacity: Ensure that the single-machine production capacity of the selected equipment can meet the requirement of 500 tons per hour, and consider the problem of capacity reduction that may occur in the long-term operation of the equipment, and reserve a certain capacity margin. For example, the model and specifications of the jaw crusher should be determined according to the production capacity requirements to ensure that its feeding and processing capacity can meet the overall requirements of the production line.

 

Energy consumption: Choosing equipment with low energy consumption will help reduce production costs. When selecting equipment, you can refer to the energy consumption parameters of the equipment and understand the energy consumption in actual operation. For example, some new cone crushers use advanced crushing technology and energy-saving design, which can reduce energy consumption while ensuring production capacity.

 

Reliability: The reliability of the equipment directly affects the continuous operation and production efficiency of the production line. Choosing equipment brands and models with reliable quality and stable performance can reduce equipment failure downtime and maintenance costs. The reliability of the equipment can be evaluated by consulting the user evaluation of the equipment, the reputation of the manufacturer and after-sales service.

Configure auxiliary equipment

Feeding equipment: Select a suitable vibrating feeder to ensure uniform and stable feeding, and avoid equipment blockage or reduced production capacity due to uneven feeding. The feeding capacity of the feeder should match the feeding capacity of the crusher.

 

Screening equipment: According to the finished product particle size requirements and production capacity, select a suitable vibrating screen to ensure screening efficiency and accuracy. The parameters such as the screen surface size, number of screen layers and aperture of the vibrating screen should meet the screening requirements.

 

Conveying equipment: Belt conveyor ensures conveying capacity and stability.

 

Dust removal equipment: In order to meet environmental protection requirements and reduce dust emissions, effective dust removal equipment such as bag dust collectors or spray devices are required to reduce dust pollution during the production process.

 

Estimated investment budget

Equipment purchase cost: The prices of equipment of different types, brands and specifications vary greatly. It is necessary to select cost-effective equipment according to the budget range. At the same time, the price and replacement cycle of the equipment's wearing parts, as well as the maintenance cost of the equipment, should be considered.

 

Installation and commissioning costs: including the installation and commissioning of the equipment and the overall layout and planning costs of the production line. Some equipment manufacturers may provide installation and commissioning services, and the cost needs to be considered in the budget.

 

- Later operating costs: such as energy consumption, replacement of wearing parts, maintenance and other costs of equipment, these costs will affect economic benefits in the long-term production process.

 

The following is an example of equipment configuration for a 500-ton-per-hour sand and gravel aggregate production line for reference:

 

Feeding equipment: You can choose zsw600*130 vibrating feeder, which has strong feeding capacity and can ensure that the material enters the subsequent crushing equipment evenly and stably.

 

Coarse crushing equipment: Using JC160 jaw crusher, with a large feed port and high crushing ratio, it can effectively handle large pieces of material and provide raw materials of suitable particle size for subsequent crushing links.

 

Medium and fine crushing equipment: For raw materials with higher hardness, you can choose one GPY single-cylinder hydraulic cone crusher and one HPY multi-cylinder hydraulic cone crusher. GPY single-cylinder hydraulic cone crusher is suitable for crushing medium-hardness materials, and HPY multi-cylinder hydraulic cone crusher is used for crushing harder materials. The combination of the two can ensure the medium and fine crushing effect.

 

Sand making equipment: equipped with a PLS1200 impact crusher (sand making machine), which has both sand making and shaping functions, and can produce high-quality sand and gravel aggregates.

 

Screening equipment: Select several vibrating screens, and perform graded screening according to the particle size requirements of the finished product to ensure that the particle size of the finished product meets the standard.

 

Conveying equipment: Equipped with a sufficient number and appropriate specifications of belt conveyors to connect various equipment to achieve smooth material transportation.

 

When actually selecting equipment, it is recommended to fully communicate with professional equipment manufacturers or technicians, and formulate the most suitable equipment selection plan based on specific production needs, site conditions and budget factors. At the same time, it is necessary to consider the upgrade and expansion space of the equipment to meet the needs of future production development.
