How to judge the rate of return of the economic efficiency of a sand and gravel production line? It mainly depends on whether the configuration of this sand production line is reasonable. An excellent configuration scheme can not only effectively increase the output of the production line, but also create economic benefits for customers. Next, let’s first understand the process flow of the sand-making production line.
First, the blasted raw stone is sent to the vibrating feeder through the loading truck through the detonator, industrial explosives, etc. from the mountain.
The vibrating feeder evenly transports the raw stone to the head-crushing jaw crusher. The jaw crusher is the first crushing, that is, the coarse crushing. The production line can be designed to be closed-loop circulatory transportation to obtain the corresponding stone particle size; then the jaw crusher is crushed. The outgoing stone is then sent to a cone crusher or an impact crusher through a belt conveyor for secondary crushing, that is, secondary crushing.
The stone material after secondary fine crushing is transported by belt conveyor to the sand-making machine for fine crushing. The finely crushed material is then screened by vibrating screen equipment to screen out finished materials of different sizes. The quality of finished materials can be determined by the sand washing machine, Dewatering screen, filter press, and another equipment cleaning. The general production line can be completed by the above three steps, but for those with strict requirements on the powder content of the sand, a sand washing machine can be added after fine crushing and screening.
Next, I will introduce how to configure the sand production line of different materials.
(The output in the following production line is only a minimum output. If it is necessary to increase the output, it can be achieved by equipping equipment with corresponding parameters according to different characteristics such as stone type, soil content, and content, water content, and discharge particle size.)
The main component of cobblestone is silicon dioxide, which has the advantages of non-toxic, tasteless, strong corrosion resistance, hard quality, and strong pressure resistance. It is the main material for the production of artificial sand and stone, and it is also green building material.
A cobblestone sand production line with an output of 60 to 100 tons per hour is equipped with: vibrating feeder + jaw crusher + sand making machine + vibrating screen + sand washing machine + fine sand recovery machine + belt conveyor
Granite is hard in texture, high in strength, wear-resistant, and weather-resistant. It has the title of “King of Rocks” and is a good building material. Granite is rich in resources, the mining cost is low but the production value is high.
A granite sand production line with an output of 80 to 150 tons per hour is equipped with: vibrating feeder + jaw crusher + vibrating screen + cone crusher + sand making machine + sand washing machine + fine sand recovery machine + belt conveyor
The main component of quartzite is silica, which is hard, wear-resistant, and chemically stable, and is an important industrial mineral raw material. Quartzite is widely used in glass, building materials, and other industries after crushing and sand making. Mainly through the quartz stone production line for finished product processing and utilization.
A quartzite sand production line with an output of 50 to 80 tons per hour is equipped with: vibrating feeder + jaw crusher + sand making and shaping machine + vibrating screen + sand washing machine + fine sand recovery machine + belt conveyor
Sandstone is a sedimentary rock, most of which is composed of quartz or feldspar and is a widely used building stone.
A sandstone production line with an output of 60 to 100 tons per hour is equipped with: silo + vibrating feeder + jaw crusher + impact crusher + sand making machine + vibrating screen + sand washing machine + fine sand recovery machine + belt conveyor
The main component of limestone is calcium carbonate, which is of medium and low hardness and is often used as building materials and industrial raw materials. Limestone sand production lines are also very common.
A limestone sand production line with an output of 100 to 150 tons per hour is equipped with: silo + vibrating feeder + jaw crusher + impact crusher + sand making machine + vibrating screen
