Characteristics of limestone sand making

Limestone is a commonly used building material and has been widely used in roads, railways, bridges, airport runways, water conservancy and hydropower dams, and urban construction materials. In the limestone sand making process, full sand making and semi-sand making production processes can be used. The specific process can be designed according to customer needs.

Limestone sand making process

The process of machine-made sand is mainly aimed at the full sand making process, namely: jaw crusher + impact crusher + high-pressure roller mill (roller mill) + vibrating screen. Auxiliary equipment can be added according to the specific needs of customers: sand and gravel powder separator, wet mixer, dust removal equipment, feeding system, dust collection device, etc.

Limestone sand production line

With the continuous depletion of natural river sand, the market demand for fine machine-made sand is increasing. Fine machine-made sand has become a new development direction and profit growth point for various sand and gravel yards. Based on years of practical experience, Dahongli Machinery has explored a complete set of machine-made sand production process to meet customers' stringent requirements for fine machine-made sand.

In the limestone sand making process, full sand making and semi-sand making production processes can be used. The machine-made sand process recommended in this article is mainly for the full sand making process, namely: jaw crusher + impact crusher + high-pressure roller mill + vibrating screen. Auxiliary equipment can be added according to the specific needs of customers: sand and stone powder separator, wet mixer, dust removal equipment, feeding system, dust collection device, etc.

Process description:

1. The vibrating feeder sends the large-size natural raw stone into the jaw crusher for coarse crushing;

2. The material is sent to the impact crusher for re-crushing, and the crushed material enters the screening machine for screening;

3.1 Oversized materials return to the impact crusher for re-crushing;

3.2 Materials that meet the particle size are sent to the high-pressure roller mill (roller mill) for sand making and screening;

4. The material after the sand washing machine enters the tailings recovery integrated machine, and the finished sand is transported to the finished product warehouse by the finished product conveyor belt for storage, and the sewage enters the sewage treatment system for recycling.

The specific process can also be configured differently according to different sites and different stones.
