Handling Petcoke made easy with Bucket Elevator

Petcoke, is a residual product of crude oil and gets its name from petroleum and coal. Petcoke is black solid waste, having high calorific value left over by various refineries/distilleries. It has high calorific value, but low volatile content, which leads to poor ignition.
Petcoke is becoming popular in today’s world and it is replacing fuel, it is acting as a supplementary fuel in various industries, due to its comparatively low price. Many industries use Petcoke. Such as Boilers, Cement Industries, Power Plants indulged into Power Generation etc. Petcoke, being a waste product but, compared to coal and other fuels have high calorific value and much lower price, comparatively.

Petcoke is a cheap fuel to be used nowadays, but, its use, creates certain problems, due to high sulphur and low volatility. Petcoke is required to be finely grounded to obtain full advantage of its calorific value, so that, it burns easily and completely. The high sulphur content in Petcoke creates operational problems in the kiln, which can normally be sorted out by using a bypass system. The Bucket Elevator can be used to make the movement of petcoke easy and possible ineffective manner, in order to utilize Petcoke with a higher percentage of Sulphur, a bypass system that withdraws 15-20% of kiln gases is required, along with it. Bucket Elevators are serving this purpose easily.

As the bypass system works together with Bucket Conveyors. We Neo conveyors, a specialist in manufacturing of bucket elevators can serve this purpose. Neo Conveyors are providing various types of conveyors and serving various industries.

Economical and safely materials handling by Incline Conveyors

Incline Conveyors, like any other conveyor, serves the purpose of the movement of material. They are used as independent units to move material from one level to another, provided used with gravity conveyor, for continuous flow of material from one floor to another.  They are designed for permanent installation by using pre-designed sections.

The material can be moved forward as well as backward, in both directions. The reverse direction requires the help of the center drive. Incline Conveyors requires support at the top and bottom. The maximum recommended incline is 25º.  As they are inclined, rough Top belt is used at the top.

In Incline Conveyor, the standard sections are combined to make any length required. They are normally equipped with NOSE OVER at the upper end, which enables the conveyed product to level off to horizontal position before being discharged.  This is highly desirable for cartons carrying breakables. The nose over eliminates a dropping action by the front of the carton when it reaches the top. Generally, the carton should not exceed the overall width of the conveyor, but if it is wider it should have a flat bottom.

 

Incline belt conveyor

Neo Conveyors, keep in mind certain facts and factors before they go for incline conveyors. They believe in the satisfaction of their customers, along with, the requirement and logical facts, such as :

  • The kind of material to be moved
  • The angle of incline required

Benefits of Bucket Elevators to handle bulk materials

Benefits of Bucket Elevators
Bucket Elevator, is a necessary useful machinery, as it is capable to convey light to heavy supplies. Bucket Elevator or Bucket Conveyor, consists of number of bucket attached for loading and transmitting the material with a strong belt to move on. It is a necessary machine, which is best suited to the oil mills, food industries, grain industries, cattle field industries, fertilizer industries, pet coke handling and various chemical industries etc.

Neo Bucket Elevators, is a system for elevating bulk materials. Nowadays, continuous developments in bucket shape, head and boot profiles, manufacturing and operating specifications are being done. Unique bucket shapes and the chains or belts as traction element and various combinations make a efficient bucket elevator.

Types of Bucket Elevators

Bucket Elevators, are serving both the inclined and vertical movement of material with ease. The most popular is a centrifugal discharge elevator, which may well be vertical or inclined. Unlike earlier elevators, small, flat steel buckets, these days modern elevators uses a rubber belt with plastic bucket, which has made them a lot more efficient and durable.

Neo Inclined Elevators, have the buckets set close together may have the discharge chute set partly beneath the head pulley. The speed of the inclined elevator is low mainly because it doesn’t rely on the centrifugal force.

Neo Vertical Elevators, on the other hand, have spaced buckets with rounded bottoms. The supplies from a boot, a pit or a pile might be readily loaded to a centrifugal elevator. The shape of buckets are triangular and close to on the belt with small or no space in between them. This kind of elevator are becoming employed to carry heavy material, and lift at a slow pace.
The principal function of elevator is to continue pulsating flow of material through a vertical handling. Apart from centrifugal discharge type, continuous variety and super capacity elevators are there to serve. Slow Elevators may be applied in case of lumpy and abrasive materials. Apart from conventional bucket elevators, shelf elevator, cradle elevators and a kind of overlapping bucket elevators etc. are in use.

Bulk Materials Handlings through Belt Conveyor

The special technique of assembly line production came into being during, the early 20th century, in particular with the business of auto moving bulk manufacturing. Belt conveyor systems, were created in the first half of the twentieth century as industrialization came into being and production was required to be improved. The automotive industry was the primary, which used the belt conveyor, to move the partially built cars, which were carried from place to another in the plant with less consumption of energy.

As it is not that easy to handle the bulk material manually, so nowadays to solve this there are various conveyors in the market. To serve this, Belt conveyors are used to transport/move materials from one place to another. The belt conveyor, is the most frequently used machine for transportation or say to provide movement to bulk material. The Belt Conveyors are gaining popularity, due to its number of benefits. A belt conveyor uses productive strategies to move components, raw material, or ready material for packaging or may be truck loading, incurring low cost and reducing labour cost.  A belt conveyor may need adjustment angle of inclination/decline. The material is usually easily accessible on the belt while it is transferred. It can be positioned, virtually any destination.

The Belt Conveyor can be made more effective through preventive repairs and maintenance. Good care for nearly any component of the mechanism will help to keep it at maximum efficiency, as well as reduce the costs of possible corrections. Although some elements of the Belt Conveyor System to be swapped, sooner or later, such as belts, lots of expensive components typically much less susceptible to degradation.

Ribbon Blender and mixers for Bulk materials

A Ribbon Blender or mixers, are gaining popularity, due to its versatile use in various industries. It has a very wiA Ribbon Blender or mixers, are gaining popularity, due to its versatile use in various industries.

It has a very wide and varied range. It is a machine, with ribbon blender agitator consisting of the inner and outer helical ribbons, which is supported by spokes wielded to a steel shaft.

When, we talk about the powder and bulk solids, the name strikes, is the ‘Ribbon Blender’, extensively used for blending, granules, flakes, pellets, drink mixes, cosmetic powders, fertilizers, chemical additives, spices, ceramic powders etc.

Ribbon Blenders to choose from depends on the type of product you want to blend or mix , whether they are similar in shape and size, and the density they possess etc.

Ribbon blenders are available in from half cu ft. to over 1000 cu ft. 1-cu-ft batch usually takes just two to three minutes to complete a cycle, whereas time for an 18-cu-ft would be 8 to 10 minutes and so on. At 100 cu ft, a 20- to 25-minute blend time is quite typical.

The ribbon blender can also “coat” solid particles with a minor component that is either a very fine powder or a liquid. In fact, its use extends to general purpose slurry or paste mixing, preparing solid-liquid suspensions, as well as vacuum drying.

Examples of wet applications include cake batter, guacamole, soups, sauces, pet food, pharmaceutical granulations, joint compounds, and plaster slurries.

Selection of Ribbon Blenders
Before, we go ahead , there are certain points to be kept in mind to achieve your target.
• The working of the ribbon blenders : Must understand the working of mixer or ribbon blender. Good design and expert fabrication. The U shaped trough allowing easy mixing of the free-flowing raw material with horizontal agitator consisting of precisely pitched inner and outer helical ribbons, which moves the materials in a balanced axial and radial flow pattern.

High-quality ribbon blenders feature tightly controlled clearances between the trough surfaces and the agitator tip.
Perfect design ensures proper and fast repeatable mixing, cleanliness, less maintenance cost, increase the life of mixer.

• Requirement of the type of Ribbon Blender , Standard or. Heavy: Firstly, judge your product and its type , the product’s actual bulk density. Consider the maximum and minimum batch quantities that a particular model can accommodate.

The perfect mixing in a ribbon blender requires a certain amount of product – at least 30-40% of the rated volumetric capacity. In case of small volumes, the blender may fail to generate adequate contact between the agitator and the product.

The size of the blender depends on the batch volume. Usually, most of the blenders can handle bulk densities of about 35 lb/cu ft.

• Belt Drive or Direct Drive : Earlier, Ribbon Blenders used a belt drive for power transmission between the motor and gear reducer, in which flexible belts and a set of pulleys, were used produced the desired speed and torque ranges.

Nowadays, the Ribbon blenders are directly driven by a gear motor over belt or chain-driven designs, as they require less maintenance and perform better. The electronic inverters give an added advantage to the Gearmotors to work extremely well, providing variable speed, overload protection, and adjustable starting torques (soft start).

Issues like belt slippage and stretching, excessive overhung load, and noise caused by chain drives are all eliminated in a direct drive ribbon blender. More advance ribbon blender, utilize a gearmotor that is essentially a one-piece motor reducer.

Wherein, motor’s low-inertia rotor is specifically matched to the characteristics of the gear unit, resulting in a high dynamic capability essential for mixing operations.

• Loading of the Raw Materials : Work of Blender starts with loading process. Either the automatic feeding system should be installed or the ingredients (dry) should be placed on the center or split equally on both sides of the blender.

This helps the operator to completely close the blender covers and all inlet ports before mixing starts. This reduces migration of dust or any loose objects from falling inside. In addition to safety limit switches must be add to it to disable the motor, if the blender cover is left open.

In case of ingredients (liquids), they are added while the ribbon agitator is running. To control the feeding a metering pump may be used alongwith the atomizing nozzles on a spray bar.

To avoid flooding testing is recommended to determine the rate of liquid addition as well as agitator speed, also multiple nozzles may be used, on both left and right sides to spray liquid to avoid lumps of material.

• Right type of Discharge Valve : Generally, product is discharged through an outlet located at the center of the trough bottom, in ribbon blender. Just for safety measure, discharge valve assembly must provide a proper seal to prevent material leakage and safety.

Powder material the Dust-tight knife gate valves are suitable, but fr liquids the Liquid-tight ball valves are appropriate and For sensitive products ‘Spherical valve or flush plug valve’ are ideal with minimal “dead spots” in the trough where product can collect.

• Introduction of controls to avoid mishaps : The ribbon blender are comparatively a simple operated machine that does not require elaborate controls beyond start, stop and speed adjustment. , but keeping in certain future need , it is useful to buy the blender with a pre-wired control panel.

Main power disconnect with lockout/tag, an energy-isolating device that can be locked out and has a prominent warning tag to protect employees from unexpected start-up or release of energy during service and maintenance.
