Weathered rock refers to the fragmentary stone after all kinds of rocks are broken, loose and the mineral composition changes under the weathering force. Weathered rock represented by limestone and marble is often found in mountain wilderness. Making it into artificial machine-made sand can not only meet some market needs, but also a good way to make money. For those who want to invest in weathered rock sand making and sand washing, how to configure the weathered rock sand making and sand washing production line? How much is a set? Let's give you a detailed explanation:
1.How to configure the weathered rock sand making and sand washing production line?
Weathered rock is generally soft rock with low hardness. After treatment by sand making and sand washing production line, it can effectively control the fineness modulus, improve the grading of weathered sand, reduce the content of stone powder, and enhance the overall crushing value, so as to make it meet the standards of sand for construction, road and other industries. The sand making and washing production line configuration of weathered rock can be divided into fixed type and mobile type, each with its own advantages.
01. Fixed weathered rock sand making and washing production line.
The advantages of fixed production are stable workplace, strong continuity of production, low purchase cost and centralized finished product warehouse. As the weathered rock materials are treated, the particle size is small, and a large part of weathered sand is mixed in them, it is suggested that sand preparation and sand washing should be carried out simultaneously. The specific production process and equipment configuration are as follows:
a. Circular vibrating screen (screening raw materials). In order to prevent the fine sand in the raw material from being crushed by the machine for many times, it can be screened once before sand making treatment, and the weathered sand with qualified particle size (≤ 4.75mm) can be screened by circular vibrating screen, and then the large weathered rock can be sand made.
b. Vibrating feeder + impact crusher (feed crushing). Large weathered rock (300-800mm) is sent to the impact crusher at a uniform speed through the vibrating feeder to crush small weathered rock stones (≤ 60mm).
c. Sand making machine (sand making and shaping). The sand making machine finely breaks the weathered rock and stone materials to make sand. Stone beating stone and stone beating iron are mixed. Sand making can also take into account the shaping of sand production.
d. Circular vibrating screen (screening finished products). The crushed products of weathered rock are further graded. The stone powder content, fineness modulus and particle gradation of weathered sand can be effectively adjusted and controlled through circular vibrating screen.
e. Sand washing machine (sand washing and quality improvement). The stone powder content is too high, which is not conducive to the allocation of qualified concrete. The sand washing machine will wash out the stone powder in the weathered sand to ensure that the stone powder content is less than 3%, so as to make it clean and beautiful and meet the sand standard for construction.
02.Mobile weathered rock sand making and sand washing production line.
Mobile production is more suitable for places where the origin of raw materials is not fixed and often need to change sites. It integrates crushing, sand making, screening and material transportation. It has compact mechanism, flexible collocation, intelligent operation and low construction and operation cost. In case of high quality requirements for weathered sand, an additional sand washer can be configured. Generally, the selected equipment configuration is: jaw mobile crusher + impact mobile crusher + sand washer (optional).
2. How much is a set of equipment for weathered rock sand making and sand washing production line?
The price of a complete set of equipment for weathered rock sand making and sand washing production line is closely related to the output design. At the same time, it will also be affected by many factors such as manufacturer, equipment quality, consumption region and so on, with considerable uncertainty. Generally speaking, the price of a complete set of equipment for fixed weathered rock sand making and sand washing production line is lower than that for mobile production line.
