Introduction To Splitters

Early microscopes were essentially a tube through which light travels (Figure 1A), from a sample to the eye (or a camera), through some lenses. Modern microscopes have a variety of objectives, mirrors, and pinholes in order to obtain the best image (Figure 1B). The component of interest here is the beam splitter.

A beam splitter is an optical device that splits beams (such as laser beams) into two (or more) beams. Beam splitters typically come in the form of a reflective device that can split beams into exactly 50/50, half of the beam being transmitted through the splitter and half being reflected. Fig.2 outlines the uses of beam splitters.

Common types of beam splitter are either cube beam splitters or plate beam splitters (such as mirrors), as described below. Cube beam splitters are made from two triangular glass prisms glued together, as seen in Fig.2A-C. The thickness of the glue is carefully adjusted so that, for certain wavelengths of light, half the light that enters the cube is reflected 90° and the other half is transmitted through the cube in the same direction as it entered, as seen in Fig.2A. Half-silvered mirrors are a sheet of glass or plastic with a very thin coating of reflective metal, usually aluminum. The thickness of the metal coating allows for half the light to be transmitted, and the other half to be reflected at 90°. An example of this mirror can be seen in Fig.1D. Dichroic mirrors are similar to metallic-coated mirrors but instead use a dichroic optical coating. Dichroic materials cause light to be split into distinct beams of different wavelengths (from the Greek dikhroos, meaning two-colored), depending on the material used the ratio of reflection/transmission can be changed. Dichroic mirrored prisms are prisms that use a dichroic optical coating and can split beams up to three times. These devices could also be used in reverse, as a beam combiner. When comparing plate/mirror and cube beam splitters, the mirror splitters can tolerate more powerful beams of light, but the cubes have far better durability and are easier to handle. While both mirror and cube beam splitters can be used for simple light beams, they can also split beams carrying an image, which makes beam splitters a powerful tool for microscopy.

The advantage of the peanut peeling machine

Peanut Peeling Machine is a very specialized equipment to dry peel the red coat of peanut. It is widely used in the previous peeling process of fried peanut, spiced peanut, peanut protein milk powder ,Rice porridge, pickled peanut and canned peanut etc. It has a high peeling rate and the peeled peanut will be kept whole, white surface and protein well. The red coat can separate with the peanut automatically when the machine peeling, and it is really efficient and easy to operate.and this machine is specially designed for peeling the inner red skin of peanuts, it takes dry process.The dry peanuts are being peeled by means of rolling and rubbing.The peanut enters the peeling room from the hopper automatically, and then the rubbing device peels the peanut to be white, scar less, and keeping whole-kernel.The Roasted Peanut Peeling Machine is with the characters of high automation,high rate of broken valve, low noise, no pollution etc.

What is color sorter machine and how does it work？

How does a color sorter work?

The raw material enters the machine from the top hopper/storage hopper. Through the vibration of the vibrator device, the raw material slides down the channel accelerate down into the observation zone in the sorting cabinet and pass between the sensor and the background plate. Under the action of the LED light source, according to the intensity and color change of the light, the output signal of the system is driven to drive the solenoid valve to blow the heterochromatic particles into the waste outlet hopper, and the accepted material continues to fall to the finished product cavity of the acceptation outlet hopper. In order to achieve the purpose of color sorting.

Understanding Compressors

Compressors are mechanical devices used to increase pressure in a variety of compressible fluids, or gases, the most common of these being air. Compressors are used throughout industry to provide shop or instrument air; to power air tools, paint sprayers, and abrasive blast equipment; to phase shift refrigerants for air conditioning and refrigeration; to propel gas through pipelines; etc. As with pumps, compressors are divided into centrifugal (or dynamic or kinetic) and positive-displacement types; but where pumps are predominately represented by centrifugal varieties, compressors are more often of the positive- displacement type. They can range in size from the fits-in-a-glovebox unit that inflates tires to the giant reciprocating or turbocompressor machines found in pipeline service. Positive-displacement compressors can be further broken out into reciprocating types, where the piston style predominates, and rotary types such as the helical screw and rotary vane.

Types of Air Compressor

Compressors may be characterized in several different ways, but are commonly divided into types based on the functional method used to generate the compressed air or gas. In the sections below, we outline and present the common compressor types. The types covered include:

Piston

Diaphragm

Helical Screw

Sliding vane

Scroll

Rotary Lobe

Centrifugal

Axial

Piston Compressors

Piston compressors, or reciprocating compressors, rely on the reciprocating action of one or more pistons to compress gas within a cylinder (or cylinders) and discharge it through valving into high pressure receiving tanks. In many instances, the tank and compressor are mounted in a common frame or skid as a so-called packaged unit. While the major application of piston compressors is providing compressed air as an energy source, piston compressors are also used by pipeline operators for natural gas transmission. Piston compressors are generally selected on the pressure required (psi) and the flow rate (scfm). A typical plant-air system provides compressed air in the 90-110 psi range, with volumes anywhere from 30 to 2500 cfm; these ranges are generally attainable through commercial, off-the-shelf units. Plant-air systems can be sized around a single unit or can be based on multiple smaller units which are spaced throughout the plant.

Diaphragm Compressors

A somewhat specialized reciprocating design, the diaphragm compressor uses a motor-mounted concentric that oscillates a flexible disc which alternately expands and contracts the volume of the compression chamber. Much like a diaphragm pump, the drive is sealed from the process fluid by the flexible disc, and thus there is no possibility of lubricant coming into contact with any gas. Diaphragm air compressors are relatively low capacity machines that have applications where very clean air is required, as in many laboratory and medical settings.

Belt feeders for efficient heavy-duty materials handling

Belt feeders is widely used in many industries ,which realize automatic production. The use of conveyor feeder system greatly improves the production efficiency and reduces the labor risk. Through the following contents, we can understand the characteristics, classification and operation of belt conveyor.

What is a belt feeders?

Belt feeder is a common feeder with big capacity, which composed of feeder hopper, discharge chute, drive and other devices etc. The structure of the belt feeder is simple, and it is easy to maintenance, conveying and installation ,which applied to many industries, such as mining ,chemical industry, metallurgy and so on . The conveyor feeder system can be design to the form of horizontal and inclined according to the requirements. And the feeder can regulate the flow of materials , which ensure continuous delivery of materials.

What types of the belt feeders?

The conveyor feeder an be divided to belt weighing feeder and belt quantitative feeder. The customer can choose the right feeder according to their requirements. The following is a brief introduction to the two belt feeders.
