SG 1 soil grinder

The Soil grinder SG 1 is designed to grind dry soil samples without comminuting plant inclusions and stones.

Soil comminution in the grinder occurs as a result of material particles being crushed by rollers.

The grain size of the comminuted product is regulated by the size of the discharge grating openings and depends on the physical properties of the material.

Operating principle:

A soil sample is fed through the charging funnel to the comminution chamber, where it enters the space between the rollers and the discharge grate.

When the gear motor is started, the forks and roller axle begin to rotate, and the rollers (both smooth and toothed) roll over the soil layer, gradually comminuting the sample.

Soil particles are comminuted to 1 or 2 mm (depending on the grate installed) and pass through the opening in the grate to the receiving container.

Solid inclusions (plants, stones) are not comminuted and remain on the grate without fouling the comminuted sample.

Advantages Soil Grinder SG 1:

• Grinding of soil components in a sample without overmilling;
• Adjustment of product grain size due to:
  • replaceable discharge grates;
  • adjustment of gap between rollers and grate.
• The folding discharge funnel provides:
  • easy removal of non-comminuted sample residues;
  • fast cleaning of comminution chamber and discharge grate.
• 90° rotation and locking of chamber for maintenance and adjustment of roller position;
• Equipped with tray for collecting sample residues and 1.5-liter stainless steel receiving container;
• Sealing of the charging funnel and receiving container reduces dust during operation;
• Reduction of vibrations transmitted to support surface by means of shock absorbers;
• Equipped with control panel and Т 70 stand.

Applications: peat, red soil, chernozem.
