Oil fracturing proppant Production Line

Since 2005, Henan Zhengzhou Mining Machinery Co., Ltd began to supply equipment and services for the ceramsite sand industry. Copperated with Henan Metallurgical Planning & Design Institute, Zhengzhou Light Metal Research Institute and Zhengzhou University Mechanical Engineering College, we set up a more than 20 people R&D team, developed new type high efficiency granulators.

During the research and development, we test more than 10 different raw materials, more than 100 tons of different raw materials. More than 10,000 times pelletizing experiments were conducted, thus we accumulated a large amount of primary information to continuously improve equipment performance and improve product functionality. The ZKZL granulator developed by our company is special equipment for pelletizing in the ceramics industry, which has the advantages of high production efficiency, full automation control, and no dust pollution.

Bauxite will be firstly crushed by jaw crusher and hammer crusher and then it will be conveyed to batching silo. After batching with other material, materials will be sent to ball mill and grinded into powder. Classifier will be used after ball mill for size grading. Here raw material will be sent to silo again. Then raw material will go to granulator and will be made into different size pellets. Pellets will be sent to screening equipment. Qualified size pellets will be conveyed to rotary kiln for calcination. Oversize pellets will be sent back for grinding.

After pellets calcined in rotary kiln, we get qualified product ceramic sand. At last, ceramic will go to cooler for cooling. And will go to screen to get different size oil fracturing proppant  and will be packed in ton bag. The production process ends.  

PROCESS FLOW CHART 

In brief, the process of manufacturing ceramic/fracking proppant is Crushing→Dosing→Grinding→Granulator→Calcining→Cooling→Screening→Packing. For more detailed information please view the production process of proppant plant.
