How to choose the right model desanding unit for TBM trenchless project

When selecting the right model of a desanding plant for trenchless project, it’s important to address key operational parameters and customer concerns to ensure optimal performance. A thorough analysis of the problem, along with understanding the specific operational requirements, will guide the solution.

One customer feedbach that the 500GPM for their new piling rig looks not performance well. They want to know what is the problem and how to address it.

Slurry Overflow: If the issue is related to inadequate processing capacity, causing slurry to overflow from the shaker screen, it suggests that the desanding plant is not handling the required flow rate.

Insufficient Separation Efficiency: If the complaint is regarding minimal differences in mud specific gravity before and after treatment, this indicates that the separation efficiency is not meeting the required standards, likely due to improper shaker screen selection or operational parameters.

Key Operational Parameters to Verify
To resolve these issues, it’s crucial to check the flow rate of the client’s mud pump. The processing capacity of the desanding plant should be carefully matched with the mud pump flow rate. If the system capacity is significantly lower than the pump flow, slurry overflow will occur. This balance ensures that the desanding plant can efficiently process the slurry without underloading or overloading.

GNMS-500D mud desaning unit Technical Specifications
For example, the GNMS-500D desander plant is designed to handle a maximum processing capacity of 500 GPM. It comes with a double deck screen shale shaker setup, including a 1mm coarse screen and a 0.3mm fine screen under the cyclone, which are crucial for separating coarse and fine solids.

Solution for Improving Separation Performance
If the desanding plant’s capacity is adequate but the goal is to reduce the gravity or solids content of the separated liquid, a finer mesh screen can improve separation efficiency. The following screen options can be considered:

Coarse Screen Options: API 20, API 40, or API 60
Fine Screen Under Cyclone: API 40, API 60, or API 80
It’s important to note the trade-off when choosing finer mesh screens. While finer screens offer better liquid clarity and more effective solids removal, they can reduce processing capacity. The finer the mesh, the slower the processing rate, so the right balance must be struck between liquid clarity and throughput.

In summary, addressing the specific complaint and aligning the desanding plant’s capacity with the pump flow, while carefully selecting the appropriate screen mesh, will optimize performance and ensure the required separation efficiency.

Manual adjustable screw conveyor VS VFD control screw conveyor

A screw conveyor, also known as an auger, is a widely used equipment for transferring drilling cuttings from shale shakers, mud cleaners (desanders and desilters), decanter centrifuges, and carrying these cuttings for feeding to drilling waste management equipment, like to high G drying shale shaker, vertical cuttings dryer, filter press, etc…. It is also widely used to discharge solids from High G dryering shaker, the decanter centrifuge, etc… It is an essential part of solids control systems, efficiently moving waste material to designated disposal areas.

When it comes to operating a screw conveyor, users often have questions regarding the functionality of the manual variable speed feature. Weather they should choose the manual variable speed reducer screw conveyor, or the screw conveyor equipped with a VFD control panel? Whether the manual variable speed unit can be removed and the motor connected directly to the gearbox to convert it into a fixed-speed screw conveyor if the variable speed unit malfunctions.

Technically speaking, if the manual gearbox fails, it is not advisable to simply connect the motor directly to the gearbox. The gearbox is designed to operate with a manual variable speed adjustment, and removing this feature would compromise the system’s functionality. In this case, it would be necessary to replace the broken gearbox with a new one to maintain proper operation.

If you need to adjust the speed frequently, the better solution is to consider using a Variable Frequency Drive (VFD) control panel. A VFD provides a more flexible and efficient way to control the speed of the motor. It allows for on-demand speed adjustments without the need for manual changes, making it particularly useful in situations where the speed needs to be altered regularly. For example, if your operations require speed adjustments on a daily basis or at different drilling rigs, a VFD system would be much more convenient and effective.

However, if your operations involve fewer require speed adjustments on a daily basis or at different drilling rigs, a VFD system would be much more convenient and effective.

However, if your operations involve fewer speed changes and the equipment is mainly used in a fixed-speed setup for extended periods, a manual variable speed gearbox might still be suitable. The lifetime of both manual adjustment and standard gearboxes is quite long, especially if the speed adjustment does not need to be changed frequently. For rigs that move between locations and require minimal speed changes, the manual gearbox remains a reliable and durable option.

In summary, if you frequently need to adjust the speed of your screw conveyor, a VFD control system is the best choice. However, if the speed adjustment is minimal and you’re comfortable with a fixed speed, replacing the manual gearbox with a new unit will restore the system to its original functionality.
