TECHNOLOGICAL PARAMETERS

EFFECTIVE COMMINUTION

Two types of rollers — smooth and toothed ensure the efficient capture of sample particles and their grinding.

PRODUCT PARTICLE SIZE AJUSTMENT

There are 2 ways to adjust the particle size of the product:

• Using of discharge grates with 1 or 2 mm openings;
• Adjustment of the gap between the rollers and the grate.

LOW DUST

Sealing of the loading funnel reduces dust during operation

EASY OPERATING

Quick-detachable plastic receiving container or box adapter for custom containers.

Completing with a tray or collecting bin (when using the support stand) for unloading plant inclusions and stones.

SELECTIVE GRINDING

Free suspension of the rollers ensures comminution of dry soil samples without grinding plant inclusions and stones.

FOLDING DISCHARGE FUNNEL

Folding discharge funnel provides:

• Easy unloading of sample inclusions;
• Quick cleaning of the grinding chamber and discharge grate.

ROTATING CHAMBER

90° rotation and locking of chamber provide easy maintenance and cleaning.

COMPATIBLE WITH DUST EXTRACTION SYSTEM

A special nozzle allows connecting SG1 Soil grinder to the aspiration system to remove dust from the grinding chamber.

EASY REMOVABLE SUPPORT WITH ATTACHED DISCHARGE GRATE

Easy cleaning due to removable support with discharge grate, which reduces the risk of samples cross-contamination and increases overall productivity by reducing downtime for cleaning.

QUALITY SPARE PARTS

The rollers and the axis of the fork are made of wear-resistant tool steel. The discharge grates are made of stainless steel.

CONIC OPENINGS

The conic openings of the discharge grate exclude jamming of sample particles in the holes, which improves the quality of sample grinding and reduces the risk of samples cross-contamination.

The Sieve shaker includes: a vibration drive, a sieving part (consisting of a set of sieves complete with cover and tray) and a sieve fastener.

The setup of the vibration drive is described in the corresponding section of the «Vibration drives» page.

OPERATING PRINCIPLE

The material to be sieved is loaded onto the upper sieve, after which the set of sieves is fixed on the platform of the vibration drive using UKS. When turned on, vibration drive platform performs high-frequency reciprocating helical oscillations, which provides a spiral-shaped trajectory of particles along the sieving surface — from the center to the periphery of the sieve. Moreover, the path traveled by the particles significantly exceeds the diameter of the sieve, which increases the efficiency of sieving. The oscillation frequency is equal to the frequency of rotation of the electric motors, and the amplitude of the oscillations depends on quantity and weight of sieves with material.

Particles of material which are smaller than the size of the sells / apertures in the sieving surface of the upper sieve fall through on the next sieve, where the cycle repeats. As a result, the sample is distributed between the sieves and the tray in accordance with the fractional content. At the end of the sieving process, the contents of each sieve are weighed and the particle size distribution of the sample is determined.
