Selection scheme of concrete production equipment

Author: admin Release time: June 9, 2017 Number of visits:

1. Concrete mixing equipment

In the comparison and selection of concrete mixing equipment, the better scheme is determined according to the basic data provided by the manufacturer. The stable product quality, preferential price, loose payment terms, convenient after-sales service, convenient operation and maintenance and low cost are fully compared and selected.

Through the comparison and selection of technical data of each equipment, Zhengzhou great wall construction machinery equipment has the advantages of strong adaptability, convenient maintenance and accessories, and good after-sales service. After comparison, HZS180 concrete mixing equipment of Zhengzhou Changcheng Construction Machinery Co., Ltd. is selected.

2. Horizontal transport equipment

All horizontal transportation is carried by concrete tank cars, which are uniformly considered as 10m3 tank cars. Assuming that it takes 90 minutes for each tank car to go back and forth on average, the effective working time is 10 hours per day, the utilization coefficient of working hours per shift is 0.9, the intact rate of tank cars is 95%, and the imbalance coefficient is 0.95%, then the number of tank cars to be equipped is 1000 / [(10 × 60 / 90) × 10 × 0.9 × 0.95 × 0.95] = 18

A total of 18 10 m3 tank cars are equipped for horizontal transportation equipment. Due to the initial trial operation, it is planned to purchase 5 tanks in the early stage and 13 tanks in the later stage.

3. Vertical transport equipment

The vertical transportation equipment is only considered as the towing pump. According to the specific situation of the commercial concrete project and the actual situation of the comprehensive investment, the towed concrete pump is equipped, and the designed delivery capacity of the towed concrete pump is 40m3 / h. The effective working time of tractor concrete pump team is 10 hours, the efficiency value of design delivery capacity is 0.75, and the utilization coefficient of unit shift is 0.8. Considering maintenance, the unbalance coefficient is 0.9 when the intact rate is 90%

The output of concrete mixer per shift is 1000 cubic meters. The number of towing pump is 1000 / [40 × 10 × 0.75 × 0.8 × 0.9 × 0.9] = 5.14

Transportation equipment configuration scale: a total of 5 towed concrete pumps, including 2 in the early stage and 3 in the later stage.
