How to select equipment for a machine-made sand production line with limestone as raw material?
Machine made sand is relative to river sand and other natural sand. Natural sand is mainly formed by the impact of natural forces, such as river sand, sea sand, mountain sand, etc. Machine made sand refers to the rock particles with particle size less than 4.75 mm made by mechanical crushing and screening after soil removal treatment.
The raw materials of machine-made sand are widely used. Limestone, river pebble, pebble, granite, basalt, bluestone and other stones are commonly used raw materials of machine-made sand. In addition, waste rock, tailings, stone powder, stone chips, leftovers and construction waste can also be used as raw materials for machine-made sand. Today, let's take a look at how to select the equipment for a machine-made sand production line with limestone as raw material.
Limestone is the stone mined from the mountain. The size of the raw ore is large. Generally speaking, a complete limestone machine-made sand production line will design three-stage crushing mode. In terms of equipment, it is mainly divided into four parts: feeding equipment, crushing equipment, screening equipment and conveying equipment.
1、 Feeding equipment
The vibrating feeder is usually used as the feeding equipment. The material is transported to the silo by truck, and then it is sent to the crusher stably, evenly and quantitatively for crushing.
2、 Crushing equipment
It is also the main part of the whole production line. Limestone is of medium and low hardness. Jaw crusher is usually used for primary crushing and impact crusher is used for secondary crushing. Stones can be produced after secondary crushing. If machine-made sand needs to be further processed, sand making machine should be selected for three-stage crushing.
3、 Screening equipment
After each section of crushing, a vibrating screen should be equipped to screen the crushed materials. If it meets the requirements, it will be sent to the next section for crushing. If it does not meet the requirements, it will return to the previous section crusher to continue crushing.
4、 Conveying equipment
Each machine needs to be connected by conveyor belt for conveying materials.
The configuration may change in different production conditions, and the specific scheme can be designed according to the actual situation.
