Ball Mill-Introduction

April 16th, 2014 by Acmas No comments »

Ball mill; an example of grinder is an efficient tool for size reduction of solid through grinding for many applications e.g. in chemical industry. Grinding means sub dividing the solids to a finer product than crushing.

Principle; Ball mill works on the principle of impact that is the size reduction of the solids is done by the impact.

Construction; a ball mill consists of a hollow cylindrical shell that rotates about its axis, this axis can be either horizontal or at a small angle to the horizontal. This horizontally shell is filled with balls; the grinding media. The grinding media that is ball can be made up of steel, stainless steel or rubber. The inner surface of the hollow cylindrical shell is usually lined with an abrasion resistance material such as manganese steel or rubber.

The balls occupy about 30 to 50 percent of the volume of the ball mill. As the cylindrical shell rotates with the material to be ground, the ball are lifted up on the rising side of the shell and then they cascade down or drop down from near to top of the cell, in doing so, the solid particles in between the balls are ground and reduced in size by impact. The ball mil may be operated in batch or continuous fashion, wet or dry.clip_image001

Importance of size reduction through grinding (Ball Mill)

Size reduction refers to an operation where the solid particles are broken down into smaller pieces, it (necessity of size reduction) is very important in application; and this process is carried out

  • To increase the surface in order to increase the rate of physical and chemical process.
  • To meet the stringent specification regarding the size of commercial products.
  • To accomplish intimate mixing of solids in solid-solid operations since the mixing is more prominent when size is small.
  •  To improve dissolution rate.
  • To improve solubility.
  • To improve binding strength.
  • To improve dispersion properties.

 

Bacteriological Incubator

Bacteriological incubator is basically the laboratory equipment which is used for the incubation of biological products under controlled conditions. This medical laboratory equipment is available with digital temperature controller with thermocouple sensor for better temperature accuracy.

They are insulated enclosures that are thermostatically regulated to maintain a constant temperature. Hot air is circulated over racks or shelves of the incubator containing the sample (such as Petri dishes, flasks or other culture media).

It is generally available with double walled construction and is made of different materials. This measuring device is the perfect product for reliable day-to-day operations that include drying, staining, and incubation of antibody tests and for microbial determination.

In this type of incubator,     environmental conditions, such     as

Temperature and humidity, can be controlled for growing bacterial cultures (37°C), hatching eggs artificially/providing suitable conditions for a chemical or biological reaction.

These units are designed to satisfy a wide array of needs of any Research Laboratory for cultivation of bacteria and for facilitating biological test.  Bacteriological incubator is also used in microbiology, biochemistry, in the dairy and food processing industries and in water and sewage treatment plants.

Tissue culture is the most important field in aqua culture, in animal husbandry and in the others biological fields to get the good hybrids and for that crucial operation, in this application the bacteriological incubator is successfully applied. This bacteriological incubator is highly reliable as this measuring instrument performs flawless and is cost-effective.

Applications of bacteriological Incubators

  • Culturing Microorganisms

This incubator provides a controlled environment that promotes the growth of microorganisms in various culture media. The first step in culturing a microorganism is obtaining a sample, whether it is saliva, blood or tissue. The sample is then placed in a culture media, such as a Petri dish, and is put into the incubator. Levels on the incubator are adjusted until temperature and humidity are similar to the organism from which the sample was extracted. Technicians monitor the growth and response of the cells in the petri dish.

  • Identify the causal Microorganism and developing the vaccines

In medicines such incubators are used to identify diseases causing microorganism taken from the patients. A sample of the patients (for whom the causal microorganism has to be identify) blood, sputum, mucus or other secretion is placed in a culture medium inside the incubator and after the microorganism in the sample has been multiplied they can be identify with greater certainty. Scientists identify harmful bacteria, develop vaccines and even create new organisms. A common application of this process is used when doctors perform a swab test for strep throat.

  • Industries

In different industries that include chemical, medical, pharmaceutical and in the biotech industry, application of this equipment is densely done (using Tissue culture).

Safety guidelines while using the bacteriological incubator

  • While using the incubator for tissue culture the door of incubator should not be open again and gain.
  • The shelves of the incubator should not be covered with aluminum foil. It may cause temperature control malfunction or an obstruction of air circulation.
  • Flammable substances are not permitted to be stored,they can be harmful.
  • Environmental conditions of the incubator for every application should be controlled properly.

Acmas technocracy is one of the leading manufacturers of Bacteriological incubator in collaboration with Weiber. Weiber bacteriological incubators are used worldwide and are manufactured from the highest quality stainless steel, and the exteriors epoxy powder coated, to give an exceptional lifespan with minimal maintenance. Weiber bacteriological incubator is available with digital temperature controller with thermocouple sensor for better temperature accuracy. They are insulated enclosures that are thermostatically regulated to maintain a constant temperature.

In Weiber bacteriological incubator; environmental conditions such as temperature and humidity, can be             controlled        for growing bacterial cultures (37 degree c) which can be further use for identification of microorganisms and development of vaccines in case of causal organisms, hatching eggs artificially/providing suitable conditions for a chemical or biological reaction. These units are designed to satisfy a wide array of needs of any Research Laboratory for cultivation of bacteria and for facilitating biological test.
