Ingersoll Rand Richler vacuum pump assisted powder material conveying.

Pneumatic conveying of powder materials, also known as airflow conveying, uses the energy of airflow to transport powder or granular materials along the airflow direction in a closed pipeline. It is a specific application of fluidization technology.

working principle

According to the working principle, pneumatic conveying can be roughly divided into suction type and pressure type. Suction pneumatic conveying is to suck the atmosphere and materials into the pipeline and transport them with low air pressure air flow, so it is also called vacuum suction. Pressure pneumatic conveying is to use compressed air higher than atmospheric pressure to push materials for conveying.

Application industry

Food industry: milk powder, flour, starch, grain, food additives, etc

Fine chemicals: pigments, dyes, coatings, carbon black, titanium dioxide, iron oxide, ceramic powder, heavy calcium, light calcium, bentonite, molecular sieve, kaolin, silica gel powder, activated carbon, etc

Pesticide ore: urea, ammonium chloride, ammonium bicarbonate, soda powder, solid pesticide, tungsten powder, pesticide additives, copper concentrate powder, pulverized coal, phosphate rock powder, alumina powder, etc

Building materials: cement, clay, yellow sand, quartz sand, clay powder, silica, limestone powder, dolomite powder, sawdust powder, glass fiber, silica, talc powder, etc

Advantages of suction pneumatic conveying

The configuration of transmission pipeline is flexible, which makes the factory production process more reasonable

The conveying system is completely sealed with less dust, and the materials will not enter the atmosphere during the conveying process, which is particularly important for the conveying of materials with high requirements or toxic materials, which can meet the requirements of environmental protection

The bulk material conveying efficiency is high, which reduces the cost of packaging, loading, unloading and transportation

It can avoid moisture, dirt and other sundries of the transported materials and ensure the conveying quality

Multiple process operations can be realized simultaneously in the conveying process

Easy maintenance and automation

It can send the materials from the centralized points to one place or from one place to the scattered points to realize remote operation

Pneumatic conveying system

Air source equipment for pneumatic conveying

In the air supply conveying system, the air supply equipment is the heart of all pneumatic conveying systems. In the design of pneumatic conveying system, it is very important to select the air supply equipment correctly.

Vacuum pump of air source equipment

Vacuum acquisition forms commonly used in suction pneumatic conveying system include oil (dry) rotary vane vacuum pump, roots pump, water ring pump, claw vacuum pump, etc. These four kinds of air source equipment have different advantages and disadvantages. With the continuous development of product technology, the advantages of claw vacuum pump have been gradually recognized and accepted by customers in recent years, and are more and more favored by the industry. Let's take a look at the respective characteristics of the four kinds of vacuum pumps commonly used in the industry.

Rotary vane pump

·  Simple maintenance, long cycle and low maintenance cost

·  The working range of vacuum degree is 150 ~ 1000 (ABS), covering the whole conveying vacuum range

Industry preferred brand

The rotary vane pump and claw pump of Ingersoll Rand's Richler brand have been widely used in the conveying process of milk powder, food powder and industrial powder. The industrial application space is huge. According to the requirements of conveying powder, the vacuum working range of the system is usually 250 ~ 600mbar (ABS.). At present, Yili, Nestle, Abbott and other giants in the dairy industry have become our users. Ingersoll Rand's Rimo Rietschle brand has become one of the preferred brands of gas source equipment in the industry.
