(1) Light slurry pump and heavy slurry pump according to the different abrasiveness of the conveying medium, the slurry can generally be divided into strong abrasive slurry and weak abrasive slurry. If the weight concentration of the slurry is C> 20%, solid relative density S> 20, solid particles d> 0.05n boron is a strong abrasive slurry, and other weak abrasive slurry is a weak abrasive slurry. Slurry pumps that transport the above two kinds of slurry are called heavy-duty slurry pumps and light-duty slurry pumps. The conveying medium of coal washing industry belongs to weak abrasive slurry, and the suitable equipment is light slurry pump.

(2) The structural characteristics of light slurry pump and heavy slurry pump The basic structure of heavy slurry pump is double shell, with volute and front and rear pump shell, which belongs to single-stage, single-suction cantilever, horizontal, axial suction radial discharge centrifugal slurry pump. This type of pump has high manufacturing cost and complex maintenance and disassembly.

The basic structure of the lightweight slurry pump is a single shell, only volute, no pump shell, belonging to a single stage, single suction cantilever, horizontal, axial suction radial discharge centrifugal slurry pump. This type of pump has the advantages of simple structure, convenient maintenance and low manufacturing cost.

At present, the heavy-duty slurry pumps developed by CNSME include zJ series slurry pumps, which have been designed and developed and put into production with nearly 100 product specifications, featuring high efficiency, energy saving, high abrasion, reliable operation and long life.

As one of the world's leading slurry pump manufacturers, CNSME is gearing up for the Canadian Mining Expo 2024. Known as the event of the mining industry, the expo brings together top companies and industry experts from all over the world and is an ideal platform to showcase the latest technologies and products.

The team at CNSME is excitedly embarking on their journey to Canada. They carry the most advanced slurry pump technology and the highest quality products, aiming to present a wonderful showcase for the mining community. Whether for high-intensity work in harsh environments or to meet customer specific needs, CNSME's slurry pumps are up to the task.

The expo will be a great opportunity to network, learn and share experiences with industry colleagues. CNSME looks forward to interacting with mining professionals and customers from all over the world to discuss the prospects of industry development, find cooperation opportunities, and work together to solve industry challenges.

CNSME firmly believes that by participating in such an event, it will be able to further consolidate its leading position in the mining market and provide customers with better quality and more reliable products and services. Let us look forward to CNSME achieving fruitful results at the Canadian Mining Expo 2024 and contributing to the development of the industry!
