sample preparation pulverizer machine

The use of a laboratory pulverizer is a must before sending any soil or test sample for titration, ICP or other assay method; you need to pulverize or fine grind a dry representative portion of the rock sample using what is commonly called in the laboratory language of sample preparation a laboratory pulverizer. Any of these term are part of the jargon to describe the pulverizing machine used to bring the particle size of your test sample down to low microns. Finer is better, and under 270 mesh (53 um) is generally fine enough.The basic parts of this vibratory type sample pulverising machine are: steel grinding bowl, ring and puck. The ring and puck rotates inside the approximately 8” diameter cage at a speed around 400 RPM or fast enough to crush and pulverize rocks of up to ½” down to 400 mesh.

Laboratory Pulverizer is an economical, simple, durable, and amazingly rapid and efficient disc type grinder. It is designed for grinding virtually any material and will produce a fine mesh sample in one operation. This unit is particularly adapted for use by assay offices and metallurgical, chemical, and industrial laboratories.

This pulverizer is the only self-contained laboratory grinder which has both a vertical and a horizontal planetary movement. Thus the rotating disc always has the proper angular curvature with relation to the stationary disc. This feature is particularly desirable due to the greatly lengthened life of wearing parts and the unusual uniformity of the final product.

The revolving disc is attached by a ball-and-socket joint with spring tension. This enables the disc to automatically align itself with the stationary disc. The constant contact of the two discs tends to perfect the crushing efficiency as evidenced by uniformity of product and high capacity of this pulverizing unit.

The main shaft is hollow. Located eccentrically within it is the disc driving shaft which, through the range of gearing, has a much greater speed than the pulley speed. The resultant high speed of the rotary disc accounts in a large measure for the exceptional capacity and fineness of product of the Laboratory Pulverizer.

Laboratory sample pulverizer is a fast, no-loss fine grinding mill

laboratory sample pulverizer is also called laboratory ring mill or laboratory disc mill. It is one of the key equipment in the sample preparation process. Efficient and accurate experimental results depend on high-quality sample grinding. Our single-bowl and multi-bowl series ring and puck pulverizers are specially designed and manufactured for this purpose.

In the sample preparation process, Jaw crusher or hammer crusher is used to roughly crush the sample. Then, the sample smaller than 25mm is finely size reduction with a pulverizing disk machine. The grinding time is generally 1-3 minutes. The particle size of the pulverized material can generally reach 120-200 mesh to meet the testing requirements of the laboratory.

The working principle of the pulverize: The motor drives the rotating shaft to rotate with high speed, which generates exciting vibration. Due to centrifugal force, the bowl puck and ring hits, squeezes, and grinds the sample to achieve the purpose of crushing.
