Production line configuration and process flow of river stone sand making machine
With the rapid development of the construction industry and infrastructure construction, the demand for high-quality sand and gravel is constantly increasing. River stone, as an important raw material, is processed into construction sand through sand making machine production lines, which has the advantages of good particle shape and high quality. This article will provide a detailed introduction to the configuration and process flow of the river stone sand making machine production line.
Main equipment configuration of the production line
The production line of river stone sand making machine usually consists of the following key equipment:
Vibration feeder: used to evenly feed subsequent equipment, ensuring that materials continuously and stably enter the production line.
Jaw crusher: As a primary crushing equipment, responsible for crushing large river stones into smaller particles.
Cone crusher or impact crusher: As a secondary crushing equipment, it further crushes materials to smaller particle sizes.
Sand making machine (impact crusher): Core equipment that further crushes and shapes the crushed material to meet the standards of construction sand.
Vibration screening machine: used to screen materials with different particle sizes, ensuring that the particle size distribution of the final product meets the requirements.
Sandwashing machine: Clean the soil and impurities in the sand to improve its cleanliness.
Belt conveyor: connecting various equipment to transport materials.
Detailed explanation of process flow
Step 1: Preparation of raw materials
River stone raw materials are transported to the silo through transportation vehicles, and a vibrating feeder is installed below the silo to evenly feed the materials into the jaw crusher.
Step 2: Primary crushing
The jaw crusher crushes large river stones into smaller particles, generally controlled below 150mm, and then sends them to the secondary crushing equipment through a belt conveyor.
Step 3: Secondary crushing
According to the characteristics of the materials and production needs, choose a cone crusher or a impact crusher for secondary crushing, further reducing the particle size of the materials to below 50mm. The crushed material is fed into the sand making machine through a belt conveyor.
Step 4: Fine crushing and shaping
The sand making machine further finely crushes the material after secondary crushing, and performs particle shaping to ensure that its particle size and shape meet the standards of construction sand. After the sand making machine discharges the material, it is sent to the vibrating screening machine.
Step 5: Screening
The vibrating screen divides the material into different particle size grades. Qualified materials enter the next stage, while unqualified materials are returned to the sand making machine for re crushing.
Step 6: Cleaning
The qualified materials after screening enter the sand washing machine for cleaning, removing soil and impurities, and improving the cleanliness of the sand. The cleaned sand is transported to the finished product storage yard through a belt conveyor.
Step 7: Finished product storage and transportation
Finished sand is stored in the finished product yard and transported to various usage locations by transportation according to customer needs.
Production line advantages
Efficient and energy-saving: adopting advanced crushing technology and equipment, with high production efficiency and low energy consumption.
High product quality: Through multi-stage crushing and screening, ensure good particle shape and reasonable particle size distribution of the final product.
Environmental protection and safety: equipped with dust removal and noise reduction equipment to reduce environmental pollution and ensure the health of workers.
High degree of automation: adopting PLC control system to achieve automated operation of the production line, reducing manual intervention, and improving production stability.
