How many meshes of mineral powder are suitable for pool leaching
Two e10.3 is enough for normal use
e10.3 theoretical power consumption is 2400W (measured: e10.1 power consumption is about 2200W, e10.3 power consumption is 3300W
at present, e10.1 model is more popular in the market. The old E10 is also good. Wing bit e10.3 as far as the current market is concerned, the heat is not high, mainly in terms of power consumption. It often appears that two 1800W power supplies can not afford one e10.3, and the computing power is not enough. E10.1 is more suitable for mining because the power consumption amplitude is not very large
XFC ultrasonic vibrating screen is recommended for filtration and screening. In the ultrasonic vibrating screen, the grid structure is improved and the ultrasonic screening system is installed on the basis of the original three-dimensional rotary vibrating screen, so that the high-precision materials below 500 can be screened effectively

Concrete mineral powder is a kind of high fineness and high activity powder obtained from water quenched blast furnace slag after drying, grinding and other processes. It is a high-quality concrete admixture and cement mixture, and is recognized as an important material for preparing high-performance concrete in the world
The grade ofS95 and S105 is a grade of mineral powder. According to the national standard GB / T18046-2000, the ore powder is divided into three grades: S105, S95 and S75, and the content of inorganic substances such as active calcium, silicon and aluminum is more than 30%
extended data
the amount of mineral powder has an important impact on the setting time and cohesion of concrete. Excessive amount of mineral powder will cause many problems in practical application. The amount of mineral powder should be reasonably determined according to the different project progress, strength grade, structural characteristics, climate conditions, etc
Whensingle mineral powder is added, 30% ～ 40% is suitable. The mass concrete can be increased to more than 50% to rece the hydration heat
Whenis mixed together, the total substitution amount should not exceed 50%. Fly ash should be controlled within 20% and mineral powder within 30%
in the initial use, it is better to control the fly ash within 10%, the mineral powder within 20%, and the mass concrete can be relaxed appropriately
for expressways and first-class highways: the particle size of mineral powder less than 0.6mm should account for 100%, that less than 0.15mm should account for 90% - 100%, and that less than 0.075mm should account for 75% - 100%
for other grade highways: the particle size of mineral powder less than 0.6mm should account for 100%, the particle size less than 0.15mm should account for 90% - 100%, and the particle size less than 0.075mm should account for 70% - 100%.
The fluidity of test mortar and contrast mortar are measured respectively. The fluidity ratio of slag powder is calculated according to the following formula, and the calculation result is taken as an integer&# 8194;&# 8194; F=(L/Lm) × 100 Where: f --- fluidity ratio of slag powder,%, l --- fluidity of test mortar, unit mm, LM --- fluidity of reference sample mortar, unit mm
the mineral powder made in China is mainly used as concrete admixture, which is proced by professional factories and added into concrete when making concrete. The amount of mineral powder is calculated by the quality of cement in concrete. In general, some gypsum can be added in the proction of mineral powder, which is generally 2% based on SO3%
extended data:
precautions:
1. Control the specific surface area and strengthen the re inspection of slag powder: the decrease of specific surface area of slag powder will bring some problems to concrete, such as the decrease of cohesion, segregation and bleeding in different degrees, the extension of setting time, the decrease of activity and the decrease of early strength, Even affect the 28d strength
The content of slag powder should be reasonably determined according to the concrete strength grade, temperature and climate characteristics, engineering structure and construction maintenance mode. When only adding mineral powder, 30% ～ 40% is suitable, and the mass concrete can exceed 50% When combined with fly ash, with the increase of concrete strength grade, the amount of slag powder graally increases, and the amount of fly ash graally decreases The setting time of concrete can be prolonged by adding slag powder into concrete, so the setting time of concrete should be adjusted, especially when the daily average temperature is lower than 10 ℃1.
