The HDD mud and water separation system produced by xi ‘an KOSUN can separate solids from the mud.

Horizontal directional drilling solid phase control through mud is the principle and technical method of controlling solid particles in mud. Solid control technology is used to remove harmful solids from the mud, retain useful solid phase, and meet the requirements of mud properties in the crossing process.

Horizontal directional drilling technology is a trenchless technology used for laying pipelines and cables when it is difficult to dig or when the cost of excavation is high. It has obvious advantages when oil and gas pipelines cross obstacles and important areas such as rivers, lakes, traffic arteries and railway hubs.

The HDD mud and water separation system produced by xi ‘an KOSUN can separate solids from the mud, so as to realize the recycling of mud. In practice, the company constantly optimizes the system to meet the requirements of various geological environments and various sizes of processing capacity and treatment. Our company not only manufacture separation systems, but also can do related engineering services. Can be tailored to the actual address requirements of customers, meet the use requirements.

When selecting the horizontal directional drilling solid control system, the main principles are as follows:

1. Particle type and size to be removed or suppressed;

2. Quality of mud to be maintained;

3. Size of drilling rig capacity, solid phase clearance rate and cycle rate.

KOSUN oily sludge treatment scheme

Oily sludge contains a certain concentration of mineral oil components, whether into the soil, farmland, arable land, or the sea, rivers, lakes, will cause serious pollution to the ecological environment or water resources.

KOSUN follow the national policy, develop the green environmental protection to repair equipment, sludge treatment and soil vibration separation, centrifugal separation technology with fluid mechanics, solve environmental waste disposal in the process of solid liquid two phase separation problems, through the subsequent processing function, reduce the pollutant emissions, recovery of available resources and meet the requirements of environmental protection of emissions standards and local government.

Why more and more clients choose to use KOSUN’s linear motion shale shaker?

Kosun’s linear motion shale shaker is a new and efficient screening equipment, widely used in mining, coal, smelting, building materials, refractory materials, light industry, chemical industry and other industries.Linear motion shale shaker is stable and reliable, low consumption, low noise, long life, vibration stability, screening efficiency.The linear motion shale shaker uses the vibration motor to excite the vibration type, causes the material to be tossed on the screen net, at the same time makes the straight line movement in front, the material enters the material inlet of the screening machine evenly from the feeding machine.The upper and lower sieves of various specifications are produced through a multilayer screen,from respective outlet eduction.With low energy consumption, high output, simple structure, easy maintenance, closed structure, no dust overflow, automatic discharge, more suitable for assembly line operation.

The linear motion shale shaker is driven by a double vibration motor. When two vibration motors are synchronous and counter-rotating, the exciting force generated by the eccentric block cancels each other in the direction parallel to the motor axis and overlapped as a resultant force in the direction perpendicular to the motor axis. Therefore, the motion trajectory of the screen machine is a straight line.Its two motor shafts have an inclination relative to the screen surface. Under the combined force of excitation force and the material’s gravity force, the material will be thrown up and jump forward to make a straight movement on the screen surface, so as to achieve the purpose of screening and classifying the material.Can be used in the pipeline to achieve automation.It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance and completely closed structure without dust overflow.The highest mesh number is 325 mesh, which can screen out 7 materials with different particle size.

Features of KOSUN linear vibrating screen:

1. The feeding box is available in skid type and box type, which can be selected;

2. Can handle drilling fluid with large specific and large displacement;

3. The screen machine is exquisitely designed and easy to assemble. One person can operate the screen machine;

4. The screen Angle adjustment device, adjustment range – 1 ° ~ 5 °;

5. Excitation strength of high G force (which needs to be adjusted according to the working condition);

6. Fast cuttings conveying speed and high processing capacity;

7. Compared with other relevant brand manufacturers, it has larger screening area and high efficiency in processing.

How Kosun’s vibrating screen works

When the vibrating screen works, the synchronous reverse rotation of the two motors makes the exciter generate reverse excitation force, forcing the screen body to drive the screen to do longitudinal movement, so that the materials on it are subject to excitation force and periodically throw a range forward, so as to complete the material screening operation.It is suitable for the screening of sand and stone in quarry, and can also be used for product classification in coal dressing, mineral dressing, building materials, electric power and chemical industry.

The working part of the vibrating screen is fixed, the material slides along the working face to screen the material.Fixed mesh screen is one of the most widely used in mineral processing plants. It is usually used for pre-screening before coarse crushing or medium-crushing.It has simple structure and convenient manufacture.Without power consumption, the ore can be directly discharged to the screen surface.The main disadvantages are low productivity, screening efficiency, generally only 50-60%.

Vibration screen working face is composed of a transverse arrangement of a rolling shaft which has a plate, fine particle material from the roller or the gap between the plate through.Large blocks of material are driven by rollers to a section and discharged from the end.This screen is seldom used in concentrating mills.Vibratory screen is cylinder-shaped, the whole screen around the axis of the cylinder mixed rotation, the axis in general is installed at a small Angle.The material is fed from one section of the cylinder, the fine grade material passes through the screen hole on the cylinder surface, and the coarse material is discharged from the other end of the cylinder.The rotating speed of the cylinder is very low, the work is stable and the power balance is good.But its screen hole is easy to block, screening efficiency is low, small working area, low productivity.Concentrating mills rarely use it as a screening device.The collective vibrating screen is a plane shaking or vibrating.It can be divided into linear motion, circular motion, elliptical motion and complex motion.shaking and vibrating screens fall into this category.When the vibrating screen is working, the two motors are placed in opposite positions synchronously so that the exciter generates reverse excitation force, forcing the screen body to drive the screen to do longitudinal movement, so that the materials on it are subject to excitation force and periodically throw a range forward, thus completing the material screening operation.Shaking screen is a crank linkage as the transmission parts.The motor rotates the eccentric shaft through the belt and pulley, and makes the body reciprocate in a certain direction by connecting rod. 

The movement direction of the body is perpendicular to the center line of the support rod or suspension rod. Due to the swinging movement of the body, the materials on the screen surface move towards the discharging end at a certain speed, and the materials are screened at the same time.Compared with the above kinds of shaker, the productivity and screening efficiency of shaker are higher.Its disadvantage is poor dynamic balance.It is now rarely used in concentrating mills and it is replaced by more reasonably structured shakers.
