Description

The R1-SKV is a combined air separator for industrial grain cleaning, rated at 100 t/h when processing wheat at 15% moisture and up to 3% weed content. It is manufactured by MELINVEST OJSC (АО «Мельинвест»), a Nizhny Novgorod-based specialist in grain milling and processing equipment with a long record of supplying mills, elevators, and grain-handling facilities across Russia.

The machine integrates three cleaning stages in one compact unit: an aspirator that strips light aerodynamic impurities in a first pass using two centrifugal fans; a circular-motion sieve body that separates impurities differing from the grain in width and thickness (oscillating at 360 ±20 rpm, radius 9 ±2 mm); and dual pneumatic channels for a final control pass that removes any residual light particles. This three-stage sequence delivers a guaranteed cleaning efficiency of at least 60% from separable weed impurities.

Total installed power is only 8.59 kW — 6.75 kW for the aspirator, 1.5 kW for the sieve body, and 0.34 kW for the pneumatic channels — giving an outstanding performance-to-energy ratio. Air consumption on the separation circuit is up to 9700 m³/h at the inlet and 7300 m³/h at the outlet, with aerodynamic resistance not exceeding 800 Pa.

Overall dimensions are 2720 × 3040 × 2800 mm with a mass not exceeding 2900 kg, so the R1-SKV slots easily into existing grain-cleaning lines without major civil modifications.

Details & Equipment

Product Overview

R1-SKV Combined Air Separator

The R1-SKV integrates an aspirator, a circular-motion sieve body, and pneumatic separating channels in a single unit measuring 2720 × 3040 × 2800 mm. The machine achieves 100 t/h throughput with total installed power of only 8.59 kW.

Three-Stage Cleaning System

Grain enters through the aspirator (primary light-impurity removal), passes through the sieve body for width/thickness separation, then flows through dual pneumatic channels for final aerodynamic cleaning — delivering ≥60% removal of separable weed impurities in one continuous pass.

Features

🌾

100 t/h Throughput

Rated technical capacity of 100 t/h for wheat at 15% moisture and 3% weed content — a high-output figure for a single combined separator unit.

⚡

Low Energy Consumption

Total installed power of just 8.59 kW (aspirator 6.75 kW, sieve body 1.5 kW, pneumatic channels 0.34 kW) keeps operating costs low relative to throughput.

🔄

Triple-Stage Cleaning

Primary aspiration, mechanical sieve separation, and final pneumatic channel pass are combined in a single machine, eliminating the need for separate aspirator and sieve units.

📐

Compact Footprint

Overall dimensions of 2720 × 3040 × 2800 mm and mass ≤ 2900 kg allow straightforward retrofit into existing grain processing lines.

🔧

Circular-Motion Sieve Body

The sieve frame oscillates at 360 ±20 rpm with a radius of 9 ±2 mm, distributing grain evenly across the full sieve width for consistent separation of coarse and fine fractions.

🛡️

Guaranteed Cleaning Efficiency

Removes at least 60% of separable weed impurities; aerodynamic resistance is ≤ 800 Pa and inlet air flow is up to 9700 m³/h for thorough pneumatic separation.

Buyer Benefits

Compact 2720 × 3040 × 2800 mm envelope fits most existing elevator and mill building layouts without structural changes
Easy-access design simplifies routine maintenance of the sieve body, aspirator fans, and pneumatic channels
Manufactured by MELINVEST OJSC, a dedicated grain-equipment producer with deliveries to all regions of Russia
Readily integrates into automated multi-stage grain-cleaning and grading lines

Applications

Primary grain cleaning at wheat and rye flour mills Pre-storage grain conditioning at grain elevators and reception points Post-harvest processing lines for removing light weed seeds, dust, husks, and straw Separation of coarse and fine impurities by width and thickness from cereal grain streams Barley and other cereal cleaning before malting or feed production Seed pre-treatment to remove light admixtures before further sorting Integration into automated multi-stage grain cleaning, grading, and blending systems High-volume grain handling at port terminals and large agro-industrial complexes
