Oil fracturing sand production process

Date: Mar. 24, 2022

The oil fracturing sand production line newly developed and produced by Longzhong Heavy Industry has the advantages of large output, high efficiency, stable operation, and round product particle size. Our company is specialized in customizing sand and gravel production lines such as quartz sand, silica sand, kaolin, potassium sodium feldspar, etc. The company has been engaged in the design and production of mineral processing equipment products for many years and has accumulated rich experience in design and production. Enterprises in the mineral processing equipment industry have had a cumulative impact and created a good brand.

The process flow of the production line is the raw material – pre-screening – scrubbing – desliming – magnetic separation – washing and dehydration – dryer – screening – a series of mud purification procedures to produce oil-fracturing sand.

Oil fracturing sand

Working principle

The fracturing sand enters the silo for storage and is screened by a linear vibrating screen. <20 meshes are subjected to magnetic separation through the magnetic separator, and then enter the scrubbing machine for washing. When the material passes through the scrubbing machine, it is fully stirred and washed, and the scrubbed sludge enters the secondary magnetic separation operation. The sand is cleaned and dehydrated in the sand washing machine, separated by the impeller separator, and then enters the lower dewatering screen for dehydration treatment, and the wastewater (containing a large amount of fine sand, mud, dust, and other impurities) overflowing from the cleaning box is cleaned. The separated sand material will flow into the mud transfer tank after being thickened by the trihydrogen purification body, and then be pumped by the special pump of the filter press, then put into the box filter press, and then filtered into the mud cake by the filter press and discharged. At the same time, the trihydrogen purification body overflows with clean water, and returns to the clean water transfer tank with the clean water filtered by the filter press, to realize the dry discharge treatment of solid waste and the recycling and reuse of water resources.

Supporting equipment: jaw crusher + feeder + vibrating screen + sand washing machine + mud dehydrator and other equipment.

Advantages and characteristics of oil fracturing sand production line

1. The overall operation of the oil fracturing sand production line reduces the pollution problem of secondary transportation of cement waste ore. At the same time, the production line is equipped with a spray system, which can reduce dust, alleviate dust pollution and achieve environmental protection in the entire production process.

2. Configuration diversity, according to the different requirements of customers, combined with the actual situation, provides a variety of personalized unit configurations.

3. The failure rate of the oil fracturing sand production line is low, which effectively improves the work efficiency, and the profit of the production line is naturally high.

4. The production line has a small area and can realize all production processes without manual operation, freeing manpower and reducing costs by 70%.

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