KOSUN’s submersible slurry pump

Although KOSUN submersible slurry pump is widely used, its correct application is very important. Due to the limitations of its name, some non-industry people have a misunderstanding of this, in the application process of submersible slurry pump, we must pay attention to the reasonable design, correct calculation, appropriate selection, these points are very important.

Installation of the submersible slurry pump:

1. Preparation before installation: check whether the water pump and motor are damaged; Prepare tools and lifting equipment; Check the basics by drawing

2. Install the support seat of the pump on the container and tighten it with bolts (for cement well tank, anchor bolts should be set in advance).

Operation of the submersible slurry pump:

1. Note that the pump bearing temperature should not exceed 35 degrees outside temperature, but the highest temperature should not be greater than 75 degrees;

2. The oil cup shall be filled with calcium-based butter to ensure normal lubrication of the bearing;

3. Replace the butter in the oil cup of motor support within the first month of operation or after running for 100 hours, and replace it every 2,000 hours after operation;

4. Check the elastic coupling regularly and pay attention to the heating of motor bearing;

5. During the submersible slurry pump‘s operation, if noise or unusual sound is found, stop immediately for inspection;

6. Every 2000 hours of pump work should be checked periodically. The wear of the clearance between impeller and pump body should not be too large. 7.

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.

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.

Analysis of Resource Utilization of Sludge

KOSUN is a professional company that provides solid-liquid separation products and integrated solutions to solid waste disposal in the fields of energy conservation and environment protection, and focuses on development and services of complete technologies and equipment in sludge reduction, harmlessness and resource utilization. The sludge treated by KOSUN vertical centrifuge can be used as various resources in the following fields:

1. Agricultural resource utilization of sludge
If the sludge is used for agricultural purposes, it has the advantages of low operating cost, low energy consumption and low investment, and the organic part in sludge can be converted into the modifier component in the soil, so this utilization way is taken as the most promising disposal method.

2. Building materials utilization of sludge

2.1. Cementitious materials utilization of sludge
For sludge, it often contains more ash, especially in the treatment of sludge in wastewater by coagulation method, which contains a lot of Fe and Al components, and can be used as additives of building materials.

2.2. Sludge ceramsite
For lightweight ceramsite, it is usually used as a flower covering material or as a concrete aggregate and roadbed.

2.3. Sludge brick
Relevant researches show that sewer sludge can be used to make ecological bricks used in construction. This kind of brick is actually made by the following process: 10% sludge is mixed into the clay and then fired at 900°C, which can optimize the effect.

3. Animal feed utilization of sludge

Sludge contains lots of corresponding substances with many useful values, such as ash content ratio of 26.1% to 46.3%, fatty acids of 0 to 3.5%, and crude protein of 28.4% to 40.8%. Therefore, it can be treated as feed protein.

4. Sludge as fuel

The sludge itself is rich in organic matter. After low-temperature carbonization of sludge, the calorific value is equivalent to lignite, so the sludge can be used as fuel with a low calorific value.

If the sludge is not treated and is directly discharged into the environment, it will be seriously harmful to the surrounding environment. After the sludge is treated harmlessly, stabilized and reduced in volume, it can be used as a valuable resource in many fields.
