electric mortar & pestle grinder

The Electric Automatic Laboratory Mortar GrinderMill Model 911MPEMG100 is used to reproducibly grind, homogenize and mix a wide range of solid materials in dry / wet or cryogenic condition. The material to be processed falls into the Pulverizing area between Mortar and Pestle by top feeding via the opening which is at the inlet cover. The material is then pulverized and mixed between the Mortar inner surface area and the bottom of the pestle. In order to match the necessary top pressure with the requested end fineness and the breaking behaviour of the sample to be prepared the MG100 is equipped with and adjustable. Top Pressure Mechanism with scale and a variable speed setting 50-130 rpm and a flexible scraper setting.

No other grinding system is more easy to clean then the Model 911MPEMG100 ElectricMortar GrinderMill. When the grinding process is finished the Mortar and Pestle can be taken out with a bayonet lock in order to perform a quick cleaning of the grinding tools.

The Electrical Mortar Grinder Mill is the central machine in todays laboratory sample pre-preparation. This system is suitable for the fine grinding of any dry substance, as well as for suspensions with different viscosities for analysis, quality control and material testing. It is perfectly suitable for the homogenization of creams and pastes. Typically samples with a feed size of up to 8-10mm and a total batch of up to 200 ml (volume depending on the characteristic of the samples) can be ground down to 10-20 m.

For finely pulverizing small samples, already reduced by means of the iron mortar and pestle to pass a No. 100 sieve, the agate mortar is indispensable; except when the ore or mineral is very soft, when a Wedgwood mortar and pestle may be used. From the size and shape of the ordinary agate mortar and pestle the operation of grinding is very tedious. It may be greatly facilitated, however, by cutting a hole, of such size and shape as to hold the mortar firmly, in the middle of a block of hard wood, a foot or so square. The pestle is then fixed in a piece of round brass tubing of sufficient bore to hold it firmly, or else in a round hard wood handle.

Some ten or fifteen years ago Mr. Maunsel White, of the Bethlehem Iron Company, designed a mechanically operated agate mortar and pestle for use in the laboratory of the above concern. This grinder is illustrated and described in Blairs The Chemical Analysis of Iron.

The McKenna Bros. Brass Co., Pittsburg, Pa., have also brought out a mechanically operated agate mortar and pestle. This is illustrated in Fig. 72. It consists of a revolving table on which the agate mortar is clamped, while the agate pestle is firmly fixed in a shaft revolving at a slight angle from the vertical. This machine reproduces almost exactly the motion used in hand grinding. The spring at the top of the sliding rod, to which the agate pestle is fixed at the bottom, can be adjusted to give any desired pressure, or can be thrown back entirely to allow the pestle to be raised in removing the agate mortar. The mortar is readily removed by loosening a set screw and dropping one of the four posts holding the mortar in place. A scraper keeps the ore in the center

of the mortar, and the combined rolling and sliding motion of the pestle, which is controlled by a ball and socket side arm, reduces the hardest ore very rapidly, no attention being required from the operator. The grinder may be operated by any convenient power, of which not to exceed 1/8 horse-power is required. The mortar used has a diameter of about 4 inches. These mortars were introduced into many laboratories and gave good satisfaction.

The agate mortar is, of course, intended only for grinding very small quantities (5 or 10 grams) of ore at a time. It has one great advantage over other forms of pulverizers in that it can be used to reduce the hardest ores to a fine powder without danger of contamination of the sample from the wear of the mortar and pestle. When soft materials, such as coal have to be ground, large Wedgwood mortars and pestles are very useful. In using these, however, the material should be merely rubbed between the

Iron mortars can be obtained in a variety of shapes and sizes. Usually for this work, however, two mortars will be found handy, one of about a quart capacity and one holding about 2 gallons. These mortars should have their inside surfaces chilled. This will make the wearing surface of the mortar hard, while the iron itself will be tough enough to withstand the blows of the pestle. If the mortar and pestle are made of steel, they should be tempered, and the temper drawn from the outside of the mortar, leaving the latter tough.

In pulverizing very hard ores, the wear and tear on the pestle and mortar is often enough to contaminate the sample, to an appreciable degree, with splinters, etc., of iron. If the material to be powdered is neither magnetic nor contains magnetic substances, the iron entering the sample from the mortar and pestle may be removed by the use of a magnet. For pulverizing samples of spiegel or white iron, mortars of high carbon steel, properly tempered and toughened as mentioned above, should be used.

Mortars having handles, or trunnions, projecting from each side to facilitate lifting and emptying are also for sale. Very heavy iron mortars may be attached to a block and tackle, so that the mortar can be lifted and emptied conveniently. The attachment can usually be most conveniently made by means of a wrought iron band or collar clamping around the upper part of the mortar and having a ring welded to it, through which the tackle may be run.

Mortars can best be set upon large blocks of wood while the pounding is going on. In order to keep the pieces of material from flying out from under the pestle and escaping from the mortar, the latter should be covered with a large piece of leather, having a hole cut through the middle for the pestle to pass through. Mortars can usually be cleaned by merely brushing out well with a stiff bristle paint brush. When material clings to the side, however, this can be removed by triturating a little clean dry sand in the mortar and then brushing this latter out.
