If a worker wants to do something good, he must first sharpen his tools. This is especially true for quarrying stone production equipment. Customers investing in a stone production line from a few hundred thousand to a few million is not a small number, a successful configuration of the stone production line can sponsor customers to quickly recover the cost, earn high profits, and a failed stone production line Will increase the investment capital and even leave the business.
Choosing energy-saving, high-yield and durable crushing equipment will be a big advantage in the cost of quarrying. The stone production line is generally composed of feeding equipment, crushing equipment, conveying equipment and screening equipment. How to choose these equipments? In order to achieve low investment, high productivity, stone material discharge granularity, and grain shape in line with the requirements of the quarry, what machine should be used to meet these requirements of the stone factory? This is before each stone manufacturer purchases equipment. All need to be considered.
Various styles of crushers have their own specialties because of their different characteristics. For example, the jaw crusher has the largest crushing capacity. It can be used to crush some hard stone materials with a jaw crusher. For example, it is used to crush unsteady stone materials, not only for large materials, but also for broken finished products, the powder may be too large, not Meet the required granularity. The crushing equipment commonly used in stone production lines is usually a jaw crusher, a counter crusher and a cone crusher.
Jaw crusher is generally used as coarse crushing equipment. According to the hardness and abrasiveness of the material, the impact crusher or cone crusher can be selected as the medium and fine crushing equipment. The impact crusher is mainly crushed like limestone, basalt, granite and concrete. , slag, cement block and other materials with low hardness and low abrasiveness, and cone crushing is mainly used to break hard abrasive materials such as iron ore, non-ferrous metal ore, granite, quartzite, sandstone and pebbles. In order to ensure high-quality, grain-shaped sand and gravel, some gravel manufacturers will add impact sand-making machines after counter-attacking or cone-breaking.
Feeding equipment, conveying equipment and screening equipment are basically not much different, but it is necessary to take into account the characteristics of the material itself. The selection of equipment should pay attention to whether the material is humid, water content, hardness, material size, especially Factors such as the time requirement. In the stone production line, the belt conveyor is generally used as the conveying equipment. The equipment has large conveying capacity, long conveying distance, stable transportation, no relative movement between materials and conveyor belt, low noise, simple structure, convenient maintenance, low energy consumption, and components. The advantages of standardization and so on are widely used in quarries, stone factories and other places.
At present, the screening equipment widely used in the production of sand and gravel mainly has a circular vibrating screen and a linear vibrating screen. Among them, the circular vibrating screen is most widely used in the production of stone materials. The amplitude of the circular vibrating screen can be adjusted, the material sieve line is long, the multi-layer screening, the specifications of each file are clear, the screening efficiency is high, suitable for mining, sand and gravel industry, suitable for quarry screening sand and gravel, also available Coal preparation, mineral processing, building materials, power and chemical industries are used for product classification. Linear vibrating screen is mainly used for the screening and grading of powdery and granular materials. It is widely used in plastics, abrasives, chemicals, medicine, building materials, grain, carbon, fertilizer, refractory materials, light industry, mining, coal, smelting. And other industries.
There are four types of feeding equipment: vibrating feeder, plate feeder, reciprocating feeder, and wave roller feeder. The four types of feeders have different delivery yields, vibrating feeders. 100-630 tons per hour, 60-750 tons per hour for plate feeders, 90-700 tons per hour for reciprocating feeders, and 150-1000 tons per hour for fluctuating roller feeders. Generally, it is a vibrating feeder. The vibrating feeder not only has a large feeding amount, but also can transport materials containing a large amount of soil and a large moisture content, and integrates the functions of screening and conveying and feeding, and can be used for removing natural fines. Material, for the next process of transmission and screening.
In summary, the complete stone production line configuration mainly includes vibration feeder, jaw crusher, impact crusher (cone crusher), circular vibrating screen, belt conveyor and other components, which are necessary for the processing of different customers. It can also be equipped with impact crushers, dust removal configurations, etc.
