Oil fracturing sand screening and washing production line

The overall fracturing sand production line is divided into five working stages, namely the raw material mining stage, the raw material drying and pre-screening stage, the raw material water washing stage, and the concentrate drying stage. It can solve the problems of fracturing sand classification, washing, tailwater purification, solid waste dry discharge, etc. The finished product can achieve round sand particle size and higher compression value. The entire production line has a large output, high efficiency, stable operation, and equipment can be configured according to customer conditions.

Production line introduction

Oil fracturing sand is a ceramic particle product with high fracturing strength, which is mainly used for downhole support in oil fields to increase oil and gas production. The 50t/h (finished product) production process design, process design, and equipment selection of a single oil fracturing sand production line, through the comprehensive consideration of the actual situation and cost-saving needs of Longding Environmental Protection Technology, the overall production line project is divided into five working stages. They are the raw material mining stage, the raw material drying and pre-screening stage, the raw material washing stage, the concentrate drying stage, and the finished product screening and packaging stage. Among them, our company is responsible for providing machinery and equipment including raw material drying stage, raw material pre-screening stage, raw material washing stage, concentrate drying stage, finished product screening, and packaging stage, etc.

Production line process

Main equipment: linear vibrating screen, square swinging screen, magnetic separator, scrubbing machine, dryer, sand-washing, and recycling integrated machine, high-efficiency deep cone concentrator (trihydrogen purification body), box filter press

The raw sand of fracturing sand enters the silo for storage and is transmitted to the vibrating screen or probability screen for a preliminary screening through the belt conveyor. <20 meshes are subjected to magnetic separation by the magnetic separator, and then the materials that enter the scrubbing machine are fully stirred and washed, and after scrubbing off the mud, they enter the magnetic separator again for the second magnetic separation operation.

After magnetic separation, the sand enters the integrated sand washing and recycling machine, the sand washing wheel rotates, the material in the cleaning box is stirred, and the cleaning operation is performed to remove the impurities covering the surface of the material. After cleaning, the coarse-grained material is sent to the dehydration by the sand wheel Sieve dehydration. The tailwater is pumped into the separator by the slurry pump, and the sediment is separated by the separator. After recovery, the fine material is discharged to the screen surface of the dewatering screen and the coarse material is evenly mixed and dehydrated before discharging.

At the same time, the sludge-water suspended matter treated by the separator is discharged into the sewage tank, and then the tailwater is pumped from the sewage tank into the concentration tank by the pump for the mud-water separation operation. The concentrated mud is pumped into the plate and the frame filter presses through the bottom of the filter tank to achieve dry stacking. After pressure filtration, the clean water enters the clean water tank to realize the recycling of clean water.

Production line advantage

1. The fracturing sand production line has the advantages of large output, high efficiency, stable operation, and round product particle size.

2. The fracturing sand grain type is round and reliable in quality. The production line has a round sand grain size and higher pressure resistance value.

3. The whole production line process realizes material washing, tailwater purification, solid waste dry discharge, and can achieve zero discharge.

4. The fracturing sand production line is highly targeted. For oil fracturing sand research and development production lines, the equipment can be configured according to customer conditions.
