Qingshi resources are abundant, and after crushing and processing, Qingshi can be made into various specifications of aggregates such as 12 and 13, which have higher industrial and economic value. So what machines are used to process 12 and 13 Qingshi? What is the specific production process for stone processing? Now let me introduce to you:
12. 13 Qingshizi is a common specification of sand and gravel aggregates, among which 12 refers to crushed stones with a particle size of 10-20mm and 13 refers to crushed stones with a particle size of 16-31.5mm. Currently, the crushing equipment that can produce such specifications of crushed stones in the market includes cone crushers, impact crushers, and hammer crushers. The main highlights of different equipment are different, and users can choose to use them reasonably according to their own needs. The specific introduction of each 12 and 13 crusher equipment is as follows:
The impact crusher adopts a triple impact plate structure, which can increase the number of material impacts, reduce hard squeezing and friction, reduce hammer head loss, and extend the service life of wear-resistant parts. The working principle of impact type is that the material is uniform and cubic in shape, without too much needle like material. The gap between the impact plate and the hammer can be easily adjusted, effectively controlling the discharge particle size. The discharge particle size is less than 35mm, and after screening, 12 and 13 stones can be obtained.
The cone crusher and the impact crusher are both two-stage crushers, but the difference is that the cone crusher adopts the principle of laminated crushing and is made of vulnerable parts made of high manganese steel, making it an ideal choice for handling high hardness materials. It can be used for crushing high hardness materials such as quartz, pebbles, and granite. There are various advanced functions such as iron protection, automatic hydraulic cleaning, and automatic lubrication to meet the different production needs of users. There is also a hydraulic system that can help users save more than 30% of labor and maintenance costs.
Hammer crusher is an equipment that combines coarse crushing with medium and fine crushing in one molding process, without the need for additional coarse crushing equipment. It can greatly save investment costs and is suitable for crushing medium and low hardness and brittle materials such as limestone, coal, cement clinker, glass, etc. It can freely adjust the discharge particle size, with good discharge particle shape and energy-saving and low consumption in production.
12. 13 Qingshi Zi Processing Production Process
Option 1: feeder+E crusher+counterattack crusher/cone crusher+conveyor
The large stones are uniformly sent to the jaw crusher for coarse crushing by the vibrating feeder through the silo, and the coarse stones are sent to the impact crusher or cone crusher for further crushing by the belt conveyor; Fine stones are transported by a belt conveyor to a vibrating screen, which screens out several different sizes of stones. The finished belt conveyor will deliver stones that meet the particle size requirements to the finished product pile; Stones that do not meet the particle size requirements are returned by the belt conveyor and sent to the impact crusher or cone crusher for further crushing, forming a closed circuit multiple times.
Option 2: feeder+hammer crusher+conveyor
With the help of the feeder, the green stone that meets the feeding particle size of the hammer crusher enters the crusher and is crushed by the impact of the high-speed rotating hammer head. The crushed material obtains kinetic energy from the hammer head and rushes towards the baffle and screen bar inside the frame at high speed. At the same time, the materials collide with each other and are crushed multiple times. Materials smaller than the gap between the screen bars are discharged from the gap. Some larger materials are further impacted, ground, and squeezed by the hammer head on the screen bar, and are crushed. The materials are squeezed out of the gap by the hammer head to obtain the desired particle size product.
