The bucket elevator is used to transport or elevate goods and materials from one place to another quickly and easily. The buckets are connected to a chain or belt which moves when the equipment starts to function. The contents of the bucket are moved from one location to another when the belt moves.
What is the purpose of bucket elevator in coal handling Mcq?
4. What is the purpose of bucket elevators in coal handling? Explanation: Centrifugal and continuous types of bucket elevators are used for lifting coal to moderate height (about 30m). It consists of buckets fixed to a chain moving over two sprockets.
How does a bucket elevator work?
Bucket elevators are designed to move flowing powders or bulk solids vertically. They are attached to an endless spliced loop of belt/chain which travels in a continuous fashion around the tail pulley/sprocket from the boot section of an elevator, where the buckets are loaded.
What is the application of bucket conveyor?
Bucket conveyors are used to transport everything from dense materials such as coal to perishable items. Products are transported and discharged gently without damage or loss. Made of durable, sanitary stainless steel, these conveyors are designed for easy washdowns.
What is the advantage of stocking the coal in huge heaps?
What is the advantage of stocking the coal in huge heaps? Explanation: Coal is piled in heaps of 10 to 12m height on a concrete floor, by compacting it in the layers of 20 to 30cm thickness using bulldozers. This prevents air circulation in the interior of the heap.
Which of the following is the simplest method of cooling the condenser water?
3. Which of the following is the simplest method of cooling the condenser water? Explanation: Spray cooling pond is the simplest method of all. The hot water coming out of the condenser is sprayed through the nozzles to expose maximum surface area of water to air for effective cooling.
How do you make a bucket elevator?
There are many variables to consider when designing a Bucket Elevator. These include bucket size, bucket spacing, speed, and various components.
|P||Power to convey the product|
|W||Weight of material being lifted|
|C||HP required to overcome the friction in the system.|
How do you calculate the volume of a bucket elevator?
STEP 1: Multiply the CAPACITY of the bucket times the NUMBER OF BUCKETS per foot (12 divided by spacing) times the NUMBER OF ROWS of buckets. This will give the capacity in cubic inches of each running foot of the belt or chain.
What is used in conveyor belt?
The most common carcass materials are steel, polyester, nylon, cotton and aramid (class of heat-resistant and strong synthetic fibers, with Twaron or Kevlar as brand names). The covers are usually various rubber or plastic compounds specified by use of the belt.
Which of the following does not include the application of material handling and transportation in food processing?
Which of the following does NOT include the application of material handling and transportation in food processing? Explanation: All of the mentioned include the application of material handling and transportation in food processing. 15. Statement 1: Cranes and hoists have an incline up and down option.
How do screw conveyors work?
A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a “flighting”, usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. … Screw conveyors can be operated with the flow of material inclined upward.
Which is the more economical way of transporting coal?
Barge transportation is the cheapest technique, but the cost depends upon the location of the inland waterways; in certain areas barges are not cost-effec- tive. For example, coal from Wyoming could be transported by rail to St.
Why is Pulverised coal used?
Pulverized coal firing ensures complete combustion of coal, thus ensuring higher efficiency of steam generators. It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion.
Which coal will have highest ash content?
Coking coal- the carbon content is around 43%-86%. It is a type of bituminous coal. Hence, lignite has the least carbon content which means that it has the highest ash content.
