How to configure sand production line

Due to the massive reduction of natural sand resources, its price all the way up, making the development of the mechanism sand industry is getting better and better, more and more people put their attention on the mechanism sand industry. The gravel production line is used to produce mechanism sand, so how should the gravel production line be configured?

Gravel production line main equipment and process introduction

Gravel production line is generally divided into feeding, conveying, crushing, screening, sand production of these parts, feeding, conveying and screening are generally used feeder, belt conveyor and circular vibrating screen, while the crushing part and the sand part of the production line is more important part of the gravel production line, the relationship between the size of the feed and the discharge, so we should be more serious to select, the following recommended a few more commonly used equipment:

1. Crushing equipment

The crushing part of the gravel production line is generally divided into a section of crushing and two sections of crushing, a section of crushing is mainly coarse crushing of raw materials, the choice of the jaw crusher. The second stage crushing is to further crush the roughly crushed stone material into fine material, generally in the cone crusher and impact crusher to choose one.

a. Jaw crusher's feed is as high as 1500mm, and the production capacity is up to 1-2200t/h, and the discharge range is also relatively large, in 10-400mm, because of its large feed, high output, large discharge, so it is often used as a section of the crushing, coarse crushing of materials. In addition, jaw crusher also has a large crushing ratio, simple structure, stable and reliable operation, environmental protection and energy saving, etc. It is widely used in building materials, roads, railways and other industries.

b. Cone crusher is the common equipment for two-stage crushing, and the difference between impact crusher and cone crusher is that cone crusher is suitable for dealing with hard materials, such as river pebbles, granite, basalt, iron ore, etc. The cone crusher is suitable for crushing materials with high hardness, such as river pebbles, granite, basalt, iron ore and so on. The feed size of cone crusher is not more than 230mm, the range of discharged material is 3-60mm, and the processing capacity is 12-700t/h. It has the features of high productivity, long service life and green environmental protection, and it is widely used in metallurgy, construction, road and other industries.

c.Impact crusher is also a common equipment for two-stage crushing, suitable for processing limestone, lime stone, coal gangue, weathered rock and other materials with smaller hardness. The feed size of the impact crusher is slightly higher than that of the cone crusher, up to 800mm, with a production capacity of 30-800t/h. It has the features of simple structure, convenient maintenance, good granularity of finished products, and low investment cost, etc. It is widely used in cement, building materials, chemical industry, and other industries. It is widely used in cement, building materials, chemical industry, coal and other industries.

2.Sand making equipment

Sand making part is in the vibrating screen on the second section of the crushed stone screening, screening out does not meet the requirements of the sand making equipment to be crushed into the sand making equipment.

Sand making part of the equipment is usually used in the sand making machine, because of its feed size is small, not more than 60mm, the discharge is only 0.55mm or so, so it is used for crushing sand making. Sand making machine can be crushed in addition to sand, but also has the function of shaping, so the finished product made of good shape, and sand making machine throughput, long service life, low maintenance costs, green environmental protection.
