Use of wet stone powder in washing machine sand

  • The use of wet stone powder in washing machine sand, artificial sand inevitably produces a certain amount of stone powder in the production process. Some people attribute the large amount of water used in artificial sand concrete to stone powder, which is considered to be harmful to concrete, but this is actually wrong. The sharp particle shape of artificial sand has a stone powder content of 10.0% C30 ~ C50 concrete, a stone powder content of 7.0% C50 concrete, and a stone powder content of 5.0%. The source of stone powder in the machined sand is formed when the rock is broken, so it is generally controlled at the source: (1) choose good quality stone,

  • Stone powder in machine sand can also be selected. In the actual production process, a dust collector with good dust collection effect should be selected, and the working condition parameters of the dust collector should be determined according to the requirements of the stone powder content in the mechanism sand. However, the method of removing the dust by the dust collector is only applicable to the production of class III mechanism. In the production process of artificial sand, it is inevitable to produce a certain amount of stone powder. Some people attribute the large water consumption of artificial sand concrete to stone powder. They believe that the mechanism of stone powder in dry-process sand is that if there are a lot of pores in the concrete, this is a problem for concrete.

  • However, this washing changes the gradation of the machined sand. The favorable stone powder in the machined sand is washed away, and only the sand is left. This defect has different effects on the concrete. The appropriate amount of stone powder is beneficial to the concrete. The existence of an appropriate amount of stone powder makes up for a dry sand production line with a mechanism: it gets rid of environmental restrictions, reduces production costs, has better gradation of artificial sand, is more environmentally friendly, and is not subject to water and environmental restrictions. Development of research mechanism Sand refers to particles of different sizes broken by rocks and sieved with a particle size below 5mm. The application of machine-made sands has started from stone debris. In the early 1980s, residential construction entered a climax. Details >> Development characteristics, main problems, all

  • Artificial sand is also called machine sand. It is used to treat mountain stones and river pebble excavated from the river through an impact crusher (also known as a sand making machine) into sand suitable for construction. In the 1990s, Zhejiang Province used large-scale sand, and worked out the details >> Background Raw materials Origin structure composition Installation and maintenance All this avoids the negative effects of concrete and cement products due to the excessive content of artificial sand stone powder and soil . Action mechanism of stone powder in dry process sand If there are a large number of pores in the concrete, this will affect the strength development of the concrete, frost resistance, and

  • The stone production line can be divided into two processes, wet sand production and dry sand production.Wet sand production is earlier. It is a water-washing sand process. The sand is washed and crushed by the sand washing machine. The mud or stone powder in the machined sand is washed away. The presence of the stone powder in 20160811 makes up for the shortcomings of the machined sand and the poor ease of preparing concrete.At the same time, it is beneficial to improve the gradation of the ultra-fine aggregate of the concrete and improve the compactness of the concrete. And then play a role in improving the comprehensive performance of concrete. because

  • Wet sand production is earlier.It is a water-washing sand process. The sand powder is used to wash the mud or stone powder in the sand between the 05mm mechanism sand separated by the vibrating screen through a sand washer, which is easily restricted by water resources. The other is a dry sand making scheme. Dry machine sand is more and more widely used in commercial concrete. This article mainly aims at the production of a large amount of waste stone powder by the sand produced by the traditional sand washing process to cause environmental pollution. New wet spraying process to increase the stone powder content in machine sand,

  • It is necessary to control the mud content in machine sand during the production process, while retaining the stone powder content. In this paper, the mud in the beach aggregate has a strong adsorption effect on the water reducing agent molecules, which makes the water reducing agent not reach the expected water reducing effect. The application of machine-made sand in commercial concrete is becoming more and more widespread. The machine sand produced by the sand washing process generates a large amount of waste stone powder and causes environmental pollution. The improved production process adopts a new dry wet spraying process to increase the stone powder content in the machine sand.

  • Artificial sand is also called machine sand. It is used to treat mountain stones and river pebble excavated from the river through an impact crusher (also known as a sand making machine) into sand suitable for construction. In the 1990s, Zhejiang Province used large-scale sand, and formulated the details >> Background Raw Material Origin Structure Composition Installation and Maintenance The purpose of both is the same, both for the higher quality of sand grains, in order to meet the concrete and dry powder Requirements for use of mortar. However, the main difference between dry sand making and wet sand making is the use of different stone powder and mud content in machine sand.

  • Stone powder in machine sand can also be selected. In the actual production process, a dust collector with good dust collection effect should be selected, and the working condition parameters of the dust collector should be determined according to the requirements of the stone powder content in the mechanism sand. However, the method of removing the dust by the dust collector is only applicable to the production of class III mechanism. Sand artificial sand is made of mountain rocks and river pebbles dug out of the river through an impact crusher (also known as a sand making machine) into sand suitable for construction. In the 1990s, Zhejiang Province used large-scale machine-made sands and formulated relevant local standards. After that, Yunnan and Beijing also issued relevant standards and rules for using machine-made sands. Successively, there are machine details in Beijing, Chongqing, Hunan and other places >> Sand making machine use
