Through mechanized production methods, most stones in nature can be processed into mechanical sand.This article answers questions about the processing raw materials, process flow and common equipment of the stone sand production line.
What stones can make sand?
There are a wide range of stone raw materials used in sand making, such as limestone, bluestone, dolomite, silica, volcanic rock, pebbles, river stone, andesite, rhyolite, diabase, diorite, sandstone, etc. in nature.In the sand-making production line, the raw materials of the stone processed are different, and the force properties and uses of the finished sand are not the same.
What are the processes of the stone sand production line?
1. Relying on the separation method of stone powder, it can be divided into “wet stone sand making”, “dry stone sand making” and “semi-dry stone sand making”.;
2. According to the equipment matching, it can be divided into “separate sand making” and “joint sand making”.
3. According to the structure, it can be divided into “plane sand making” and “floor sand making”.
What is the process of the stone sand production line?
Regardless of the scale of the stone sand production line, the production process is usually divided into the following stages: mine block stone → coarse crushing → secondary crushing → shaping sand making→ screening and grading → mechanism sand → sand washing (not necessary).
What are the commonly used stone sand making equipment?
In the stone sand production line, a variety of equipment must work together.The supporting feeders, vibrating screens and conveyors are almost the same in the selection, mainly due to the reasonable matching of the crushing system and the sand making system.The granularity of the finished sand is greatly affected by the sand making machine. Due to the better shape of the sand processed by the impact sand making machine, it has a high degree of recognition in the industry. The following are several common stone sand making equipment configurations.
1. Jaw breaking machine + cone breaking + impact sand making machine (or floor sand making system);
2. Jaw breaking machine + counterattack breaking + impact sand making machine (or floor sand making system);
3. Jaw breaking machine + cone breaking + impact sand making machine (or floor sand making system);
4. Hammer breaking machine + shaping machine + dual-rotor sand making machine (or floor-type sand making system).
What are the advantages of the stone sand production line?
1. The processed stone is rich in raw materials, and the physical properties can be selected.Through mechanized and industrialized production methods, the particle size, fineness modulus, and particle gradation of the finished product are relatively stable, adjustable, and can be improved.
2. Convenient management. After applying for a sand site permit, there will be a fixed production site, factory and commercial operation.Compared with river sand mining, it is more conducive to ecological balance and contributes to the sustainable development of enterprises.
3. The automated operation process has high efficiency and large processing capacity, which provides qualified materials for high-level highway, railway, water conservancy, concrete mixing station and other industries.
