Equipment used: 1 feeding machine ZSW1860, 1 type jaw crusher PEV950*1250, 1 set of disc feeder ZZG2020, 1 set of impact crusher PF1520, 1 set of circular vibrating screen 2YK2170, 1 set of circular vibrating screen 3YK3075
The limestone crushing production line in Yunnan is another successful case of our company in the crushing market of Yunnan mine. The finished materials of the project are mainly used by local commercial mixing stations and highway materials. According to customer demand, the finished product is divided into four specifications: 0-5mm, 5-15mm, 15-26.5mm, and 26.5-31.5mm. The design yield is: 200 square meters per hour.
The crushed raw material is limestone CaCO3, and the hardness is above 120Mpa. The original stone is exploited by open-pit blasting, the maximum particle size is less than 800mm, and the mud content is more than 10%. The raw materials after blasting are transported to the loading platform by the double-bridge transporter, and the load per vehicle is about 25 square meters.
The transporter transports the blasted raw materials from the material table and pours it into the silo from the material table. The feeder ZSW1860 is fed into the jaw crusher PEV950X1250 for crushing, and the jaw crusher discharge control is within 250mm. The semi-finished material after the initial breakage is input into the intermediate silo by the conveyor belt for stacking, and has been prepared for processing.
The feeder is designed with a purlin design. The stone and soil of less than 200mm in the raw material are separated by the purlin of the second half of the feeder, and a 2YK2170 is used for the powder screening by the conveyor belt to sort out the soil and crush. stone. The sorted gravel is input into the intermediate silo for stacking, and the soil portion is treated as roadbed material or scrap.
According to the site situation, the intermediate silo has a design reserve of about 1000 squares, and a ZZG2020 vibrating feeder is designed at the bottom of the intermediate silo. The crushed semi-finished raw material is crushed by a conveyor fed by a conveyor belt into a large impact crusher PF1520. The crushed stone is fed into the vibrating screen 3YK3075 by the conveyor belt for the finished product. The finished products after sieving are stacked by conveyor belts according to different specifications.
This is the first time that we have cooperated with Chengdu Dahongli Machinery Co., Ltd., and after the comparison of several equipment manufacturers, we finally chose Dahongli, and also comprehensively inspected the good reputation and enterprise strength of Dahongli crushing equipment in the market. decided. Dahongli's designers have considered the entire production process design very well, saving the venue and installation costs to the greatest extent. After more than a year of use, the current output has exceeded the design output, reaching 360 tons / hour. Very satisfied with the product quality and after-sales service of Dahongli Machinery.
