Sending equipment is the starting point of a pneumatic conveying system. It feeds bulk material from a hopper or silo into a pipeline, creates pressure, and moves the product to a destination. Our pneumatic conveying sending equipment is designed for reliable, low-maintenance, energy-efficient transfer of powders, granules, and other bulk solids. We provide dense phase senders, dilute phase feeders, and custom pressure vessels for every application.

As a professional sending equipment manufacturer, we produce pressure conveying tanks, also called blow tanks, pressure pots, or pneumatic senders. Both stainless steel and carbon steel options are available. Stainless steel sending equipment is ideal for food, pharmaceutical, and chemical plants where hygiene and corrosion resistance are required. Carbon steel sending equipment suits mineral, cement, sand, fly ash, and heavy industrial applications where strength and abrasion resistance are key.

Product types include single-chamber blow tanks, twin-chamber alternating senders, top-discharge blow pots, bottom-discharge blow pots, and side-discharge pressure vessels. Twin-chamber systems allow continuous conveying. Top-discharge designs are often used for long distances. Bottom-discharge configurations handle fine powders at higher pressure. Each unit can be supplied with pneumatic valves, level sensors, PLC controls, and a complete piping package.

Working principle: material enters the tank through a filling valve with the vent open. After filling, the inlet and vent valves close. Compressed air is introduced to pressurize the vessel. When the set pressure is reached, the discharge valve opens and the material moves into the pipeline. Supplementary air prevents blockages. The cycle is fully automatic and repeats continuously.

Key advantages include certified pressure vessel manufacturing, optimized discharge to avoid dead zones, high-quality pneumatic components, and custom sizing according to material properties, distance, and capacity. Surface treatments include pickling, passivation, sandblasting, and painting. Stainless steel and carbon steel options give customers flexibility in cost and durability.

Applications cover food, chemical, mineral, building materials, power, and pharmaceutical industries. Typical products include flour, starch, sugar, milk powder, plastic pellets, cement, lime, fly ash, sand, and pharmaceutical powders. Dense phase senders are widely used for ash handling and abrasive materials. Customized solutions are available for biomass, recycled materials, and other unique bulk solids.

Material selection is critical. Stainless steel senders are made of SS304, SS304L, SS316, or SS316L. Carbon steel equipment uses Q235B or Q345R plates. Wall thickness is calculated according to working pressure and material abrasion. Wear-resistant ceramic or steel liners can extend service life. All pressure parts are fully inspected and pressure-tested before delivery.

Standard volumes range from 0.5 to 15 cubic meters. Working pressure can be up to 0.6 MPa or higher. Capacity ranges from hundreds of kilograms to over one hundred tons per hour. Our engineers can calculate pipe diameter, air consumption, sender volume, and valve size based on your site conditions. Explosion-proof components and special flanges are available for hazardous areas.

Price depends on material grade, vessel size, wall thickness, working pressure, valve brand, control system, and conveying distance. A standard carbon steel single blow tank is economical. A stainless steel twin-chamber system with PLC and explosion-proof controls is higher in price but offers greater productivity and safety.
