Gravel production line consists of vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor and centrally electric control devices and so on; design output of 50-500 tons/hour. In order to meet the customer's processing needs, and can be equipped with a cone crusher, dust removal equipment. Hard limestone, granite, basalt, river gravel, metallurgical slag and other materials can be used to aggregate and artificial sands operations, applies to the application of water, building materials, highway, city construction and other industries. According to the different technical requirements, various types of equipment combinations, meet our customers' process requirements.

(1) the design basis of the general program of the crushed stone production line

Dust pollution sources of the production line mainly from stone crushing, screening, conveying the dust in the process, dust is the main component is calcium carbonate and free silica.

2 gravel dust control principles

Limestone crushing process, in order to achieve the purpose of dust control a significant effect, and reducing equipment investment and lower operating costs but also to ensure that the equipment long-term and stable operation, the engineering design to the following principles:

2.1 technologically advanced equipment and reliable

Dust control systems engineering, the key is the selection of the dust collector. In order to ensure the long-term stability of the entire system, dust collector should be used by the long-term practice is indeed a reliable technology.

2.2 System parameters

To achieve the expected results, to determine the process parameters of this system is very important. Therefore, it is necessary to correctly estimate the dust production of a variety of dust-producing equipment, and industrial ventilation design requirements of equipment layout and pipe network to the system air flow distribution for accurate calculation.

2.3 to facilitate the maintenance and management

Transformation as far as possible and reliable vulnerability, the process is simple, reduce the system failure rate and maintenance of equipment rates. Taking into account the easy maintenance of the host device.

3 Cleaning System program design

Because the distance between the site of each dust equipment in the proper range. In this way, as long as the last two precipitators can solve the full capacity of dust and equipment as well as several conveyor belt of dust pollution. This design to be adopted by the two exhaust fan, all dust exhaust compliance efflux vacuum hood, duct, dust collector filter.

4 dust collector selection

The choice of the baghouse according to the nature of the broken exhaust can a simple, efficient solution to such dust control, and easy to manage. To this end the program on the two systems use air box pulse bag filter.

The engineering design selection of efficient bag filter, the addition to the performance characteristics and the optimization of the dust removal system to meet the design performance to an overall improvement in the quarry environment to address the overflow phenomenon of the past, quarry dust, dust collector, exports of emission concentration ≤ 30mg/Nm3 energy efficiency to improve the operating environment to protect the physical and mental health of the operatives.
