What is the difference between an oilfield drilling fluid shaker and a conventional shaker?

　　 Oilfield drilling fluid shaker It consists of an exciter, a slurry distributor, a screen frame, a frame, suspension springs, and a screen mesh. Oilfield drilling fluid shakers (high-frequency screens) feature high efficiency, small amplitude, and high screening frequency. The operating principle of oilfield drilling fluid shakers differs from that of conventional screening equipment. Because oilfield drilling fluid shakers (high-frequency screens) operate at high frequencies, they not only break the surface tension of the slurry but also cause high-speed oscillation of fine particles on the screen surface, thereby accelerating the separation and liberation of high-density useful minerals and increasing the probability of contact between particles smaller than the separation particle size and the screen apertures.

　　The oilfield drilling fluid shaker is a conventional vibrating screen equipped with an ultrasonic device. Compared with conventional vibrating screens, however, the oilfield drilling fluid shaker is better at handling difficult-to-screen fine materials, making the screening of ultrafine powders no longer a challenge and particularly suitable for users of high-quality fine powders.

　　 Oilfield drilling fluid shaker It has advantages over conventional vibrating screens.

　　1. Screening accuracy

　　The screening accuracy of ordinary shakers generally fluctuates around 60%, but with the addition of an ultrasonic device, it can reach over 95%. This is why, when users encounter fine and ultrafine powders that are difficult to screen, they first think of oilfield drilling fluid shakers, as these shakers can often achieve very high screening accuracy.

　　2. Network Congestion Issue

　　Ordinary vibrating screens can cause caking and material leakage, whereas oilfield drilling fluid shakers use transducers to convert electrical energy into wave energy that is transmitted to the screen surface, thereby breaking up caked materials and ensuring more thorough screening. In addition, they can clean the screen mesh in multiple directions, effectively solving the problem of screen clogging.

　　3. Screening Speed

　　During the screening of powdery and granular materials, its performance is several times that of conventional screeners, thereby reducing screening costs for enterprises and delivering substantial benefits.

　　4. Production

　　Compared with ordinary vibrating screens, the screening capacity of oilfield drilling fluid shakers can be increased by 0.5 to 10 times.

　　5. Screen Lifespan

　　High utilization rate, resistant to clogging, quick start-up, rapid screening, and long service life.

　　6. Screening Effect

　　The materials include all-stainless-steel construction, all-carbon-steel construction, and a stainless-steel screen mesh with a carbon-steel base. Stainless steel is hygienic and durable but relatively expensive; carbon steel is less robust. The equipment can perform simultaneous screening across 1 to 6 layers or multi-layer screening, resulting in clearer material classification. Screen replacement is quick and straightforward. In the screening of granular materials, screen damage is inevitable, so rapid screen replacement is an effective way to enhance efficiency, improve durability, and reduce long-term maintenance costs. Its compact and lightweight design facilitates easy relocation of materials, further extending its service life. The operating principle relies on a vibration motor that provides sufficient power to induce vibration in the screening unit; particles smaller than the screen apertures are vibrated downward to the lower layer, thereby achieving layered separation—layer-by-layer classification.
