How to Configure Hard Rock Sand Production Line?

How to configure hard rock sand production line?

Speaking of pebbles, people who know the sandstone industry will definitely say that pebbles are high-quality raw materials for machine-made sand processing and hard rocks. The use of cobblestone as sand can be widely used in many fields, such as railways, construction, and municipal administration. Generally, coarse crushing, medium fine crushing and shaping processes are used to process raw materials to finished products. The sand produced can be comparable to natural sand and can replace daily. The depleted natural sand effectively relieves the contradiction between supply and demand in the sand and stone industry, and is also one of the reasons why more and more investors pay attention to the cobblestone sand production line.

However, for the processing of hard stones such as pebbles, the quality requirements of the equipment required by the production line are generally higher. The pebble sand production line can be divided into three steps from before feeding to after discharging, which are crushing, screening and manufacturing. Sand, these three steps are interlocked, and each production line needs different pebble crushing or sand making equipment. The entire production line is down to one million and as many as ten million. How much does it cost? It also needs to be calculated according to different production capacity, finished product specifications, production site, equipment investment budget, etc.

According to the required particle size of the finished product, a crushing process can be divided into coarse crushing section, medium crushing section, fine crushing section and grinding section, and general materials can be divided into coarse crushing + medium crushing, coarse crushing + medium crushing+ fine or coarse crushing + medium crushing + fine crushing + shaping three major types of process engineering, shaping is generally to make the resulting product better shape. The crushing products commonly used in the whole crushing process are as follows:

The jaw crusher is used in the first crushing process of the crushing line, which can crush large particles with a compressive strength not exceeding 320MPa to a size of 40mm~300mm.

The impact crusher can generally process ore or rock below 800mm, and the crushed materials are cube particles. The impact crusher is generally used in the second crushing process of the crushing line. It can also be used as the first crushing process for materials with small input.

The cone crusher uses the principle of lamination crushing to form a protective layer of the material layer. It has the characteristics of reliable structure, high crushing efficiency, easy adjustment, and economical use. The feed particle size is 25~450mm. Cone crushing is the same as the impact crushing. It is often used in the second crushing process of the crushing line. It can also be used as the first crushing process for materials with small input materials. However, the feed particle size of cone breaking is generally smaller than that of impact crushing.

The sand making machine is suitable for the crushing and shaping of soft, medium hard and extremely hard materials. It is generally used as the last process of the crushing sand production line. The feed particle size is 5~60mm.

In addition to the main crushing equipment, some auxiliary equipment such as vibrating screens, feeders and conveyors are needed to complete the configuration and work of this production line.
