Mining slurry pump   is a kind of   mineral processing equipment   which increases the energy of solid and liquid mixed medium by centrifugal force (the impeller of slurry pump rotates). In the concentrator, the slurry pump is mainly responsible for slurry transportation, feeding, pressurization, emission, etc., and its investment cost accounts for a significant proportion in the infrastructure investment of the concentrator and later production and maintenance costs. In the production, due to the transport medium of the mining slurry pump generally contains solid particles, and the fluid particles erosion, medium corrosion, cavitation, etc., the wear speed of wet part is very fast, the service life is generally short. Therefore, how to improve the wear resistance of the wet part and reduce the investment cost has been an urgent problem for concentrators. In order to solve this problem, Shandong Xinhai Mining Technology & Equipment Inc (Xinhai Mining for short)...

Compared to the traditional alloy plate,   rubber liner   of ball mill is more popularized by its unique advantages. Generally, alloy plate has a lot of problems, such as long time-consuming, complicated installation, replacement difficulties, etc., besides, its wearing resistance is not as good as the rubber liner. Finally, rubber liner is widely applied in many mineral processing plants for its small density, easy to processing and strong wear-resisting. However, not all ball mill rubber lining boards are featured with strong wear-resisting performance like Xinhai super wear-resisting rubber liner. As the only one wet natural wear-resisting rubber manufacturer in China, Xinhai makes the content of natural rubber reaches 95%. In addition, Xinhai has passed the appraisal of Xinhai wet rubber production wear-resisting key technology and industrialization from National Technical Committee of Science and Technology, which is about the special liquid nano formulations—room te...

Pump is widely applied in the mineral processing plant, which provides the motivation of pulp conveying. Here are two kinds of slurry pumps that we will introduce to you— alloy slurry pump   and   submerged slurry pump .      In the mineral processing, it is evitable that slurry pump meet different problems. Then, we will explain how to solve these common problems of slurry pump: Alloy Slurry Pump 1. Why do not the slurry pumps absorb the slurry? (1) Reason: Impeller is damaged Solution: Replace a new impeller (2) Reason: suction pipe blocked Solution: Unclog the pipe 2. Some tips before using slurry pump: ﹒ Pumping clean water lasts 30 minutes to wash off the slurry in the pump and pipes before closing the pump; ﹒ Closed end pump outlet valve; ﹒ Stop it from the end pump to the first stage pump step by step, then close the corresponding seal water and cooling water; ﹒ Close the inlet valve of the first stage pump; ﹒ Don’t close all ...

               Xinhai   XPA type wear-resistant slurry pump   is a horizontal material conveying pump, which can be used in mine, metallurgy, electric power, coal, chemical industry, building materials, etc. The service life of slurry pump is generally lower in the ore dressing process, especially used for conveying abrasive materials. Therefore, the wear-resistant performance of slurry pump is the most concerned problem for users. Xinhai XPA type wear-resistant slurry pump adopts top   wear-resistant rubber   that is outstanding in wear-resistance. Its corrosion resistance, high elasticity and high strength have very good protection to the pump, which makes XPA type wear-resistant slurry pump become the best choice for conveying abrasive pulp or corrosive liquid containing solid material. Sealing is another standard to evaluate the performance of slurry pump. All   Xinhai slurry pumps  adopt three kinds of ...

Slurry pumps   are widely applied in mines, coal, electricity, water, environment and other industries. The wear problem of wet parts is the most serious in material conveying. The fast wear of pump liners causes the short service life of pump and waste of manpower, material resources and financial resources. The aspects below would help to solve the wear problem: Adopt advanced design theory and model The main reason causing wear and damage of slurry pump is the impact and wear of solid materials in conveying. So it is useful to design pump according to solid-liquid two-phase flow theory which considers the changing relationship of the solid-liquid two-phase velocity field and knows the variation of concentration ratio. Select reasonable impeller parameter 1. Inlet diameter design of the impeller blades Inlet diameter of impeller has a certain influence on flow capacity, wear level of wet parts and hydraulic efficiency of slurry pump. If the blade diameter is too sm...
