BLOWER
(HIGH-FLOW LOW-PRESSURE PUMP)

Positive-displacement air station for uninterrupted pneumatic conveying and dust filtration

A high-efficiency positive-displacement low-pressure pump for the pneumatic conveying of grain and floury products through pipelines and for the pulse (shock) cleaning of bag pores in jet-pulse bag filters in flour, semolina and feed mills. Thanks to its sophisticated rotor geometry it produces a high air flow in a constant-pressure regime, giving stable aerodynamic power plant-wide.

WORKING PRINCIPLE

Acoustic atmospheric-air reception — positive-displacement air suction: the blower takes atmospheric air into the body through a suction silencer and high-porosity filter group; the counter-rotating twin- or triple-lobe rotor design drives the air toward the outlet by positive displacement without compressing it. Aerodynamic resistance and power management — line pressure and flow stability: the high-flow, low-pressure air the device produces is delivered to the system under the control of a safety valve and a discharge silencer; the air stream keeps its stability while resisting the vertical/horizontal distances set in the plant diagram and the elbow losses along the line. Pneumatic conveying and jet-filter pulsing — dual-function industrial discharge: the stable air stream produced is distributed to two critical operations: grain or flour is conveyed in the pipes without loss, while simultaneously the bag pores in the jet-pulse filters are cleaned by reverse flow (shaking).

KEY ADVANTAGES

- Engineering-focused line and elbow loss calculations: The blower model choice is determined by a precise calculation based on the conveyed product’s specific gravity, the hourly target capacity, the total vertical and horizontal route length and the friction losses from the number of industrial elbows on the line.

- High-flow low-pressure technology: Compared with compressor systems, it can produce huge air volumes (flow) at much lower pressure values; this delivers excellent shaking without damaging the fabric structure of the jet-filter bags.

- Maximum maintenance and installation ease: The compact chassis allows easy installation with minimum floor occupation; consumable replacement and periodic oil changes are extremely practical owing to quick service covers and an accessible design.

- Model variety to suit process flexibility: It is made in a great variety of industrial types and models to suit the plant’s main air requirements, installed power capacities and the physical constraints of the mounting area.

ENGINEERING NOTE

The blower is the fundamental energy source for both the logistics flow and environmental sanitation in the milling industry. Its positive-displacement operating principle prevents the air flow from dropping even when product concentration rises in the pipeline, eliminating the pneumatic-line clogging risk. The cool, dry air circulation it provides during flour conveying preserves flour quality, while the stable volumetric air support it gives the jet-pulse filter diaphragms lowers compressor costs and maximises the plant’s specific energy efficiency.
