Quartz Sand Production Line

Quartz sand production line mainly consists of : Vibrating Feeder, Jaw Crusher, PCL straight-through type centrifugal crusher(sand making machine), Vibrating Screen and tape transmission machine. Some quartz sand production lines also need Ball Mill.

flow chart of Quartz sand production line

Dry quartz sand production line is that: crushing-separation-rough selection-fine selection-air separation- dust collection. That is to say from one side quartz sands come into equipment and all kinds of qualified products will come out from the other side then the products will be directly put into bags.Wet quartz sand production line is that: crushing-separation-rough selection-fine selection-air separation- dust collection.

Firstly, the stones are primary crushed by coarse crusher. By the tape transmission machine, the coarse materials are sent to fine crusher for next crushing. Then the stone materials come into Vibrating Screen to be divided into two kinds of stones: the ones that meet the feeding particle size will come go into sand making machine to be made into sand and others are crushed again. Parts of stones that come go into sand making machine are made into sand and others come into the machine for next crushing.

Performance of quartz sand production line

This quartz sand line features with high automaticity, low operating cost, high crushing ratio, energy-saving, large production, less pollution and simple maintenance. The final mechanism sands comply with the national building sand standards and features with uniform particle size, good particle shape and reasonable gradation.

Quartz Powder production line

Quartz powder production line is used for manufacturing quartz powder by grinding mill. These Quartz Powder that includes Quartz Grits, Quartz Sand, Quartz Silica and Quartz Grains are used for various applications in Foundry, Construction, Abrasive blasting, Railroad and Water purifier.

Productive Technology & Process of Quartz Powder

1. Dry-type production of quartz powder

The main quartz powder production plants are crusher, grinding mill, vibrating screen, etc. The technological process is: Firstly, materials are crushed by plants of rough crushing and secondary crushing (like roller-type crusher). Then, through vibrating screen, where magnetic bar and magnetic chip are used to remove iron, or autogenous tumbling mill is directly used to grind sand with sands treated by air classification. Finally, sands can be split charged and sent to warehouse.

2. Wet-type production of quartz powder

The main plants are crusher, stone roll, curing barn, vibrating screen, water way system, etc. Generally, the technological process is: After rough crushing, secondary crushing process, wet-type grinding plants (like rod mill, pebble mill, stone roll) are adopted to grind quartz ores, and hydraulic separation is used to classify powder lot. For example, through stone roll, materials become sands, keep water adding all the time during this process; sands, along with water, flow into settling pond, then roasted to dry sand in curing barn; through vibrating screen, where magnetic bar and magnetic chip are used to remove iron, sands can be split charged and sent to warehouse.

Production Equipments of Quartz Powder

The common production plants of quartz powder are: rough crushing plants (jaw crusher, cone crusher, etc.), secondary crushing plants and grinding plants (rod mill, pebble mill, etc.), and screening plants (vibrating screen, shaking sieve, etc.)Matters need attention in production of quartz powder

1. In addition to hardness of quartz, size of particle, composition, dimension of discharge hole and loose condition of materials in crushing cavity are all the factors that influence features of products.

2. When fabrication plants of quartz start crushing materials, the bigger the size of feeding materials, the smaller the size of products, no matter the crushing of charge bank or crushing of single particle. For this reason, in production, proper jaw crusher and dimension of discharge hole should be chosen according to size of feeding materials.

3. Crushing of charge bank of quartz crusher can better reduce size of products than crushing of single particle. Keeping proper thickness of feed layer in crushing cavity of crusher in production, so as to reduce size of crushing products. The primarily crushed segments, whose kinetic energy occupies 45% of the whole crushing energy, hit against metal plate in air, which obviously generates the second crushing.
