KOSUN’s screw conveyor is widely used in various industries.

KOSUN’s screw conveyor is widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal mine coal, food and other industries, applicable to horizontal or oblique conveying powder, granulated and small lump materials, such as coal, ash, slag, cement, food, etc., the material temperature is less than 200 ℃.Screw conveyor does not transport perishable, viscous, easy to agglomerate materials.In the concrete mixing station, the screw conveyer’s function has obtained the biggest embodiment.

When the screw shaft rotates, the material can only move forward along the bottom of the conveyor under the push of the blade due to the gravity and friction generated by the wall of the tank, which is like the translational movement of the nut that cannot be rotated along the rotating screw rod.The movement of materials in the intermediate bearing depends on the thrust of materials moving forward from behind.So the transport of materials in the conveyor is a complete slip movement.In order to make the screw shaft in a favorable tension state, the drive device and discharge port are generally placed at the same end of the conveyor, and the feeding port is placed near the tail of the other end as far as possible.The rotating screw blade pushes the material forward for conveying, and the force that prevents the material from rotating together with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor housing on the material.The profile of the blade can be divided into solid profile, belt profile and blade profile according to different materials.The screw shaft of the screw conveyor has thrust bearing at the end of the movement direction of the material to counter the axial force of the screw with the material. When the length is longer, the intermediate suspension bearing should be added.

Screw conveyor in the use of the process, must pay attention to the daily maintenance, so as to ensure maximum production and efficiency, but also make the service life of the equipment extended.

1. Lubricating oil should be added to the transmission parts such as bearings, gears and chains on a regular basis;

2. After the screw conveyor is out of service, the wear condition of the screw blade shall be checked, and if the wear is serious, it shall be repaired by welding;

3. The conveying quantity shall not be overloaded, otherwise the material cannot be discharged, causing the screw shaft to bend and the box to swell and damage;

4. When the conveying medium has a high degree of mobility, pay attention to whether the expansion and contraction of the box body is free and there is no stuck place;

5. When the conveyor is in operation and the noise is harsh, the cover shall be opened for inspection and troubleshooting.

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.

What’s the Solid Control System consist of?

Kosun as the professional solid control system manufacturer, we have our own understanding about this system.In Kosun’s words, solid control system is also called drilling fluids purification system, primarily applied for solids control and solid-fluid separation in drilling fluids so that the drilling mud might be recycled. Consisted of 3-7 module composite tanks and configured with 4 phases of purification equipment, it is fit for 2000-7000 meter oil drilling processes. The whole system is innovative with the bottoms of its purification tanks made to be conical and its edges equipped with mud agitating system to prevent solids from depositing. Besides, its tanks and bins may be comparted or united depending on the demands of drilling processes. Each of them is connected to another via pipe network in which the valves at the bottom of suction pipes are flexible while being opened, but can turn to be a good seal when closed.

What’s the  Solid Control System consist of?

Solid Control System

The first main equipment for solid control system should be the vacuum degasser,We could analytics from the function of vacuum degasser. Generally speaking, horizontal vacuum degasser will be used to separate the gas from the drilling solids. What’s the reason to do like that? Because we should do everything to prevent any dangerous elements in oil & gas drilling fields. That’s why we should put the vacuum degasser as the first role.

The second one should be mud cleaner. KOSUN MD Series Mud Cleaner is the second stage separation equipment for drilling fluids, which deals with the mud being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.

The third equipment, we think it should be shale shaker (with necessary steel frame shaker screen). Actually, after the drilling solids have been transported and fed into vacuum degasser and mud cleaner, the third step is going with shale shaker. Commonly, we still need to be transported the solids onto the shale shaker, or we could say onto the surface of shaker screen. The equipment of transporting we should use is centrifugal sand pump or screw pump; and we may use shear pump to cut the drilling solids into small one if they are in big size. With the different design of the shaker screen’s mesh, we could get the drilling solids separated in different sizes.

The fourth equipment should be the decanter centrifuge. KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G. In solid control system, decanter centrifuge has been popularly used, which is also the popular one for drilling waste management. In this step, we could not only get the result of separating, but also we could separate the oil from the drilling solids, even if the oil is just a little part.

Of course, the whole equipment must be mounted on the top of drilling mud tank, which is a kind of basic equipment for both solid control system and drilling waste management (vertical cutting dryer is the core equipment for this system), but it is a kind of powerful equipment.
