HOW IS CALCIUM HYDROXIDE PRODUCED FROM LIMESTONE?

Calcium hydroxide, also known as slaked lime or hydrated lime, is typically produced from limestone through a process called slaking. Here are the steps involved:

Quarrying: Limestone is extracted from quarries and transported to a processing plant.

cylindrical desulfurizer

Calcination: Limestone is heated to a high temperature (around 1000°C) in a lime kiln to produce calcium oxide (also known as quicklime). This process is called calcination and drives off carbon dioxide from the limestone, leaving behind calcium oxide.

Slaking: Quicklime is then mixed with water in a process called slaking. The water causes a chemical reaction that produces calcium hydroxide:

CaO + H2O → Ca(OH)2

What are the vibrating screen parts?

A vibrating screen is a mechanical screening device used to separate materials into various sizes for further processing or end use. It consists of a screen deck, vibrating motor, springs, and other components that work together to provide a high-capacity and efficient screening solution.

The material to be screened is fed onto the screen deck, which vibrates rapidly to move the material along and separate it into different sizes. The size of the openings in the screen deck determines the size of the material that passes through and is collected in a chute or hopper below the screen.

High frequency dehydration vibrating screen

There are several parts that make up a vibrating screen, including:

Screen deck – the surface on which the material is screened, typically made of wire mesh or perforated plate.

Vibrating motor – the power source that drives the vibrating motion of the screen deck.

Springs – components that support and cushion the screen deck and absorb vibrations.

Bearings – components that support the rotating shaft of the vibrating motor and reduce friction.

What is the working principle of banana vibrating screen

A banana vibrating screen is a specialized vibrating screen used in the mining and quarrying industries. It is designed to be able to handle a high capacity of material, while also screening it to a very fine size. The banana screen gets its name from its shape, which is similar to that of a banana, with a curved surface at the feed end and a flat surface at the discharge end.

The working principle of a banana screen involves the use of multiple screen decks that are arranged at different angles to each other. The screen decks are typically mounted on a frame that is supported by springs or other flexible elements, which allow the screen to vibrate freely.

Linear vibrating screen

As the material to be screened is fed onto the screen deck, it is spread out evenly across the surface of the screen. The curved shape of the screen deck causes the material to move along the length of the screen, with the smaller particles passing through the openings in the screen and the larger particles moving to the top of the screen.

The vibration of the screen deck helps to loosen and stratify the material, separating it into different size fractions. The use of multiple screen decks at different angles helps to increase the screening area and improve the efficiency of the screening process.

WHAT IS THE DIFFERENCE BETWEEN OPEN DIE AND DIE FORGING?

Open die forging and die forging are two common forging processes, but they differ in the way the metal is shaped and formed. Here are the key differences between the two processes:

Equipment: Open die forging is done using large hammers and presses to deform the metal into the desired shape, while die forging uses a set of dies (also known as molds) to shape the metal. The dies are typically made of steel and are designed to withstand the high temperatures and pressures of the forging process.

Rocker arm forgings

Process: In open die forging, the metal is placed on a large anvil and struck repeatedly by a hammer or press, which deforms the metal into the desired shape. The metal is not confined by the dies, which allows for more flexibility in the shape and size of the final product. In die forging, the metal is placed between two dies, which are then pressed together to shape the metal. The dies are typically designed to create a specific shape or form, and the metal is pressed until it fills the cavity of the dies.

What is the difference between crossed roller bearings and ball bearings?

Crossed roller bearings and ball bearings are both types of anti-friction bearings, but there are some key differences between them:

Construction

Ball bearings consist of a series of small metal balls held in place by a cage, while crossed roller bearings have cylindrical rollers that are crossed at a 90-degree angle and alternately arranged between inner and outer rings. The crossed roller bearings have a more complex design than ball bearings, and they tend to be more rigid and precise.

Crossed roller bearings

Load capacity

Crossed roller bearings are designed to handle higher loads and higher rotational speeds than ball bearings. The crossed roller bearing’s crossed arrangement of rollers distributes loads evenly and reduces the risk of roller slippage. Ball bearings, on the other hand, are typically used for lighter loads and lower rotational speeds.

Accuracy

Crossed roller bearings offer a higher level of accuracy than ball bearings. The crossed rollers are preloaded to maintain a certain level of accuracy and reduce the effects of clearance or deflection. Ball bearings have more clearance between the balls and the raceway, which can cause some degree of play and reduced accuracy.
