Lapis lazuli crushed stone processing process and equipment selection

Lapis lazuli is widely used in building and infrastructure construction due to its excellent physical properties such as high hardness, wear resistance and compressive strength. In order to process large blocks of lapis lazuli into crushed stone suitable for different application scenarios, a set of scientific and reasonable processing process and suitable equipment are required. In this article, we will introduce the process of lapis lazuli crushed stone processing in detail, and recommend the efficient equipment suitable for each link.

1. Raw material preparation process

Collect natural lapis lazuli from the mine or quarry, and carry out preliminary cleaning to remove surface impurities and soil, to ensure the smooth progress of subsequent processing.

2.Primary crushing process

a. Equipment selection: Jaw crusher is ideal for primary crushing. It has strong pressure resistance and wide adaptability, and can effectively crush large pieces of greenstone.

b. Operation points: Control the feed size, avoid oversized materials into the crushing chamber. Adjust the speed and power according to the actual demand to ensure the best crushing effect.

3.Intermediate Crushing Process

a. Equipment selection: Cone crusher is the best choice for intermediate crushing. It can provide higher crushing ratio and better product shape, and is suitable for occasions with high requirements on particle size.

b. Operation Points: Adjust the size of discharge opening to control the granularity of the discharged material. Regularly check the wearing parts and replace them in time to ensure the normal operation of the equipment.

4. Fine crushing and sand making process

a. Equipment selection: impact crusher is the ideal equipment for fine crushing and sand making. It can produce high-quality crushed stone with even particle size and good grain shape, which is especially suitable for road paving and concrete aggregate.

b.Operating Points: Adjust the rotor speed and feeding speed according to the requirement of finished products. Equipped with efficient dust removal system to reduce dust pollution.

5.Screening and grading process

a. Equipment selection: Vibrating screen is the commonly used screening equipment, which can accurately separate the gravel with different particle size.

b. Operation points: choose the appropriate screen specification according to the requirements of the finished product. Clean the screen mesh regularly to prevent clogging and ensure the screening effect.

6.Washing and storage process

a. Equipment selection: sand washer is used to clean the sediment in the crushed stone to ensure product quality.

b.Operation points: Control the water flow and washing time to avoid excessive washing affecting the output. Store the cleaned gravel in a dry place to prevent moisture.
