High purity quartz sand has a wide range of applications, including glass products, electronic product assembly, construction and decorative materials, and jewelry products. High purity quartz is obtained by processing and purifying quartz ore. Quartz purification requires the construction of a quartz production line, which is composed of multiple equipment. So what are the equipment for the high-purity quartz production line? How to choose the manufacturer of production equipment? Below is a brief introduction.
1. Crushing equipment
The crushing equipment is responsible for crushing large pieces of quartz ore into small pieces. Usually, coarse crushing is completed by jaw crushers, while medium and fine crushing are completed by cone crushers and hammer crushers. The crushing stage requires the cooperation of auxiliary equipment such as feeders and vibrating screens to complete the crushing task.
2. Grinding equipment
The crushed small pieces of ore are fed into the grinding workshop through a belt conveyor, where a rod mill is usually used to complete the grinding operation of quartz. The reason for choosing a rod mill is because it has a large output and uniform grinding particle size, which can avoid overgrinding. The fineness control device of the rod mill can adjust the discharge particle size.
During the grinding stage, a hydrocyclone or obstructed settler is required for grading operations, in conjunction with a rod mill to complete the grinding task.
3. Scrubbing equipment
There are two types of scrubbing machines: spiral scrubbing and stirring scrubbing. When dealing with coarser particle sizes, a spiral scrubbing machine can be selected. If the mud content is high, a stirring scrubbing machine is preferred.
4. Flotation equipment
Flotation is a key step in quartz purification, which can separate quartz from gangue minerals and remove impurities such as mica, feldspar, and aluminum from quartz, thus achieving the goal of quartz purification. There are corresponding methods for separating quartz ore from mica and feldspar, and you can click on the link to refer to the previous article.
In the flotation stage, a flotation stirring tank is required to complete the slurry stirring work before flotation, so that the gas, medicine, and ore can be fully integrated in order to achieve good flotation results.
5. Magnetic separation equipment
The content of iron impurities in quartz is also relatively high, and the presence of iron lowers the purity of quartz, making it difficult to meet the quality standards of high-purity quartz. Therefore, iron removal is also an important step in quartz purification, and equipment such as magnetic separators and high gradient magnetic separators are generally used for quartz iron removal.
6. Dehydration equipment
The selected quartz sand needs to undergo dehydration treatment, and equipment such as thickeners, filter presses, and high-frequency dehydration screens are required during the dehydration stage.
The dewatering stage requires the use of a slurry pump to complete the transportation of the slurry.
The above equipment constitutes a complete high-purity quartz sand production line. In this production line, each equipment performs its own duties and completes its own tasks. After going through the steps of crushing, grinding, scrubbing, magnetic separation, flotation, and dehydration, the final purification of the original quartz ore is completed to obtain high-purity quartz sand.
There are many manufacturers producing high-purity quartz sand equipment in the market, so how to choose a suitable manufacturer? Here are some ideas for you.
1. Must have relevant project experience
We know that the development of beneficiation and purification processes should be based on the characteristics of the ore itself, and representative ore samples should be taken for beneficiation experiments to determine the final beneficiation process flow. The determination of process flow is closely related to the experience of process designers.
Therefore, when choosing a manufacturer of high-purity quartz sand equipment, it is important to look for experienced manufacturers who have done many quartz sand purification projects. Such manufacturers are generally able to accurately locate the beneficiation process, allowing for greater recovery and purification of raw ore, and avoiding resource waste.
2. Has a research and development team with production capabilities
The quartz sand purification production line is composed of multiple equipment combinations, and the performance and compatibility of each equipment all affect the final purification effect. Therefore, when choosing a manufacturer of high-purity quartz sand equipment, it is necessary to choose a manufacturer with a research and development team and production capabilities. The equipment is produced by oneself, with better natural continuity and smoother production lines.
3. Can provide EPC+M+O services
After the construction of the high-purity quartz sand production line, there will be a long period of automated operation. If any problems occur during this process, it is important for the equipment manufacturer to provide follow-up services. Therefore, it is recommended that you choose a manufacturer that can provide full mining industry chain services (EPC+M+O) and provide you with full beneficiation process services, which will save you worry, effort, and money.
The above three points are important aspects of examining quartz sand purification equipment manufacturers. Since its establishment, Xinhai Mining Equipment has completed multiple quartz sand beneficiation and purification projects, all of which have achieved good results. The recovery rate and purification indicators can be achieved or exceeded.
Xinhai has its own beneficiation design institute, product research and development department, and a complete production workshop. All equipment is independently developed and produced, and can provide customers with EPC+M+O services. It can meet the expected production standards within the expected time, and is a high-quality quartz sand purification equipment manufacturer.
