KOSUN Construction Mud Solid-liquid Separation Equipment

  1. Linear Dewatering Shale Shaker – Construction Mud Solid-liquid Separation Equipment
    Linear Dewatering Shale Shaker is specially designed to separate larger and coarser solid particles. The construction mud enters the shale shaker through the feeding funnel, and separates large-diameter solids such as large stones. The screen on this shale shaker has a longer lifespan than traditional woven screens.
  2. Double-layer mud Shale Shaker
    After being screened by the Linear Dewatering Shale Shaker, the liquid phase enters the Double-layer mud Shale Shaker again. The Double-layer mud Shale Shaker is a two-stage separation. It first enters the bottom layer of the Double-layer mud Shale Shaker. The mesh number of the bottom layer is smaller, and the coarse particles are further screened. The mesh number of the upper screen is higher, and the liquid phase passing through the bottom screen enters the upper screen again, and the effect is better.
  3. Mud cleaner
    The liquid phase screened by the Double-layer mud Shale Shaker is pumped to the mud cleaner. The mud cleaner consists of two 10-inch desander cyclones and 12 4-inch desander cyclones plus a shale shaker. The liquid phase first passes through the desander cyclone, and then enters the desliming cyclone. After separation by the mud cleaner, the material conditions for entering the centrifuge are reached.
  4. Decanter centrifuge
    The separation capacity of the decanter centrifuge is more refined. In order to ensure a good use effect, the requirements for the materials entering the centrifuge are relatively strict, so the front coarse screen, fine screen and cleaner are processed. The centrifuge can separate solid particles above 2-5um. After the centrifuge treatment, it meets the customer’s requirements.
  5. Flocculation dosing system
    The flocculation dosing system is the icing on the cake. When the level required by the customer is higher, the flocculation dosing system can make the centrifuge more effective.

Composition of Geothermal Drilling Solids Control System

Geothermal energy is a new green and clean energy. With the increasing awareness of environmental protection and the shortage of energy, the rational development and utilization of geothermal resources has become more and more popular. The geothermal drilling solids control system came into being under the requirement of drilling environmental protection. According to the characteristics of geothermal drilling and the environmental protection requirements of geological drilling, KOSUN has developed a miniaturized multi-stage drilling fluid solids control and circulation system composed of mud shaker, mud cleaner, drilling fluid centrifuge, etc. Easy to relocate and other characteristics, it can realize the circulating treatment of drilling fluid without falling to the ground, and effectively remove harmful solid phase.


The drilling fluid centrifuge adopts the modular design of single motor structure, and the minimum separation particle size is 5μm. It can be matched with the frequency conversion control system to realize stepless speed regulation and adapt to the characteristics of different formations. The mud cleaner organically combines a hydrocyclone with a shale shaker, which can remove harmful solids from 20μm to 74μm. The drilling fluid solids control circulation system can match the solids control equipment according to different drilling requirements, which changes the traditional drilling fluid natural settlement treatment method, reduces the environmental pollution caused by the drilling fluid discharge, meets the needs of clean production, and meets the requirements of green exploration and green drilling. The liquid phase recycling and solid phase centralized recycling and processing in the cycle process meet the national requirements for energy conservation and emission reduction.


On the basis of the research on the geological drilling solid control system, in order to support the high-temperature geothermal clean energy exploration requirements, a skid-mounted modular five-stage solid control and drilling fluid cooling system has been formed, which can meet the needs of drilling fluid treatment and cooling in high temperature environments, and is a high-temperature environment. Geothermal (hot dry rock) drilling provides effective technical support.

6 Types of Piling Mud Treatment Equipment

At present, regarding the mud treatment of construction piling projects, there are 6 main types of piling mud treatment equipment. According to the different requirements of piling projects, how can we correctly use a type of the 6 types of piling mud treatment equipment that suits our project requirements? Please let me introduce these 6 piling mud treatment equipment in detail for you, so that you can choose a piling mud treatment equipment that is really suitable for you according to your actual engineering situation!

1) Mud processing equipment of stacked screw centrifuge: the filter main is formed by the fixed ring and the floating ring stacked on each other, and the screw shaft runs through it.

body. Fully dewatered by gravity concentration and the internal pressure formed by the back pressure plate during the propulsion process of the sludge, the filtrate is discharged from the filter seam formed by the fixed ring and the movable ring, and the mud cake is discharged from the end of the dewatering section.

  1. Centrifugal mud treatment equipment (decanter centrifuge) The working principle is that the equipment consists of a rotating drum and a screw conveyor with a hollow rotating shaft. The sludge is fed into the rotating drum by the hollow rotating shaft. thrown into the drum cavity. Due to the different specific gravity, solid-liquid separation is formed, and the sludge is transported to the conical end of the drum under the push of the screw conveyor and continuously discharged from the outlet; the liquid in the liquid ring layer is continuously “overflowed” and discharged to the outside of the drum. Gravity discharge.
  • Vacuum suction filter mud treatment equipment: due to the action of vacuum, the sludge immersed in the sludge storage tank is adsorbed on the filter cloth. When the drum rotates to the backflushing area, the adsorbed sludge is removed by the compressed air backflushing sludge filter cake.
  • Screening cyclone mud treatment equipment: the coarse screen of the vibrating screen first screens the large particles in the mud, and then enters the cyclone in the desander and the fine filtration process of the fine screen of the vibrating screen. The mud was successfully realized in the state of mud-water separation.
  • Plate and frame filter press mud treatment equipment: This equipment mainly uses the principle of plate and frame extrusion in a closed state, so that the water in the sludge is discharged through the filter cloth, and the sludge is trapped between the filter cloths. , in order to achieve mud dewatering.

6) Belt filter press mud treatment equipment: The working principle of this equipment is that it is formed by a series of rollers in an S shape, and the capillary water in the sludge layer is squeezed by the tension of the filter belt and the pressure of the rollers, so that the mud The water in the slurry is squeezed out to achieve the purpose of solidification and dehydration of the mud.

The above 6 types of piling mud treatment equipment can solve various problems of piling mud treatment for you very well. Regarding the selection of equipment for mud treatment in construction piling projects, consideration should be given to the efficient utilization of mud recycling, water reuse and turning waste into treasure, reducing pollution and harming the environment, water pollution, environmental protection and energy saving, convenient transportation and low cost, and efficient production. High dehydration rate, economical benefits, reduced construction cost, easy operation and maintenance, high degree of automation, long service life and many other factors.
