The SP shear pump produced by KOSUN can quickly prepare high-performance slurry.

The SP shear pump produced by KOSUN can quickly prepare high-performance slurry, greatly shorten the preparation time of slurry, and improve the economic benefits of drilling.

Shear pump is a machine specially designed for shearing polymers and clays and has been used in the field and proved effective in theory. In the drilling fluid system, polymer (or clay) should be sufficiently in advance after shearing, again into the drilling fluid system, in order to give full play to its functions, improving drilling fluid performance, if there is no sufficient shear, polymer in the first cycle could jam vibrating screen mesh, lose a massive amount of polymer, to increase the drilling cost, and may also make the large size of solid phased particles in drilling fluid hard and difficult to get rid of; In drilling fluids, the polymer produces many “fish-eyes” due to insufficient shear. These “fish eyes” can harm the formation, reducing permeability and reducing oil and gas production.

The shear pump provides a high degree of shear for rapid hydration of polymers (or clays) and resolves prominent problems with poorly hydrated polymers (or clays) in drilling fluids. At the same time, the use of shear pump can make the polymer injection amount reduced by more than 15%, the dosage of bentonite reduced by more than 30%, and improve the mud cake and fluid flow loss, reduce drilling fluid shear rate, improve the gel strength, has reached the advanced level of similar foreign products, the shaft seal structure is more reliable, excellent performance, the use of maintenance more convenient.

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.
