Portable Abrasive Blasting Machine

The portable abrasive blaster are safe, high productivity systems designed for use with a wide range of abrasive media. The operation is performed on metals, glass, ceramics, plastic and stone.

The machine works on pressure blasting principle, consist of a blast generator. The abrasives are filled at the top of machine when machine is not working and blast generator is not pressurized. At the top, a vibrating sieve is provided to sieve the abrasive filled. The oversize abrasive and debris are retained on the screen, thus prevent the choking of blast line. When mushroom valve is opened the abrasive will get transferred to blast generator for blasting. The mushroom valve gets closed when compressed air is switched on and abrasive storage tank gets pressurized, for free fall of abrasive into the mixing tube. From mixing tube the abrasive is carried away by compressed air to the nozzle for blasting. The Blast Generator is fabricated from MS Steel plate of thickness not less than 6 mm as per IS-2825 and hydraulically tested for 250 psi.

BLAST ROOM

DESCRIPTION

Blast room is a complete device that can be used for sand blasting of objects of different shapes and sizes. For the process it can be used either metal or mineral abrasive.

Transport of workpieces in the blast room is usually carried out by means of a forklift or on the trolley, usually across the rails. Sand blasting process is carried out by sandblasting pistol, which is directed by the worker on the surface of workpiece. The sandblasting pistol is connected by means of the sandblasting pipe with the pressure vessel, from which the abrasive comes with the compressed air at high speed.

During sandblasting process the worker must be adequately protected with a protective clothes, gloves against the impacts of the abrasive and dust special helmet for head protection.

The blast room housing is rubber-protected. The continuous abrasive returning and cleaning system can have screw conveyors  or scraping conveyors applied to the whole shot blasting chamber surface or only part of it. Different platforms for working on heights, devices for spinning rotated treated object around longitudinal axis and abrasive sucking devices provide high work efficiency.

PULSE JET BAG FILTERS

HIGH RATIO PULSE JET BAG FILTERS control particulate emissions and pollution levels. Bag material and air-to-cloth ratio are selected based on application requirements. The bags are supported internally by wire cages which do not impart any load onto the bag. Inspection and maintenance doors are built-in, and platforms and ladders are provided as per requirement. Industries like foundries, cement, mini steel plants, sponge iron plants, power plants, material handling, mining, plastic working, woodworking, and metalworking generate high levels of particulate emissions, which are now closely monitored and regulated by government bodies and legislation.

SEQUENCE OF OPERATION

Dust-laden air enters the unit through the hopper or at the plenum, and clean air flows out of openings in the bag hanging plate. The accumulated dust is removed from outer bag surfaces at regular intervals by short pulses of compressed air introduced into the bag through a solenoid operated pulse valve. A PLC operates the pulse jets in sequence at predetermined intervals. Dust collected in the hopper is discharged through screw conveyors and/or rotary air lock valves. The message is clear — if you want to lower your particulate emissions, our bag filters can do the job for you effectively and reliably. Talk to us today to see how we can help.

OSCILLATING CONVEYOR

 OSCILLATING CONVEYORS are utilized to convey sand or other granular particles at a desired rate. The conveyor is generally placed under a vibrating shakeout or a grid to eliminate direct handling of hot sand by the belt conveyor. In the process of reciprocation, the oscillating conveyor cools the hot sand to some extent which increases the life of the return sand conveyor belt.

CONSTRUCTION

The equipment comprises a metallic trough carried on inclined arms which are fitted with rubber bushes to handle the reciprocating motion of the trough. The oscillating motion of the trough is achieved via specially designed inclined arms and an eccentric shaft driven by a motor through V-belts.

OPERATION

The eccentric shaft is mounted on anti-friction bearings and has V-pulleys at both ends with weights on them to counteract the unbalancing force. The rotation of the eccentric shaft provides a forward and backward motion to a connecting arm attached to the trough through a rubberized pin. A retaining spring assembly at the back of the trough absorbs shock load.

SHOT BLASTING MACHINE VKP SERIES

Discription:

Overhead conveyor shot blasting machine with hook is typically designed   to  handle mixed loads of medium and large components which often include fragile and sensitive parts that cannot be tumbled in bulk loads. Overhead conveyor shot blasting machines with hook are ideal for heavy and complex shaped work pieces like: casts, welded constructions, forged and pressed parts, remodeled cold or hot and of various complicated forms, steel bottle, springs, etc. Parts can weight from 5 kg to 10,000 kg, manufactured in medium and large series.

This type of shot blasting machines are mostly used for continuous blast cleaning, desanding and decoring in die cast industry as well for descaling, derusting and reconditioning in metalworking industry. Treated objects are hanged individually or in a cluster on revolving hooks on a closed loop conveyor going through the shot blasting machine. In the process of shot-blasting the treated objects revolve and move back and forth in a jet of abrasive media, which provides best possible uniform blasting results.

Overhead conveyor shot blasting machine with hook housing is protected by wear-resistant manganese steel liners or entirely made of manganese steel and additional protection of the most exposed wear areas. High efficiency of the blasting machine is provided by the automatic and continuous abrasive handling and reclamation system for continued returning and cleaning of the shot blasting media, along with efficient blasting wheels made from wear-resistant materials. Standard equipment of larger VKP shot blasting machines includes: PLC, display, timer, automatic or manual mode, pneumatic cylinders on the door, revolving hooks, automatic start-up of throwing wheels, working-hours counter, etc. VKP blasting machine may be equipped with a magnetic separator, vibration conveyor and variable frequency drive for the throwing wheels.

For emptying the blasting machine, the belt rotation is switched in the opposite direction turning mode. When the blasting machine works in automatic mode the treated objects are loaded into the blasting machine by hydraulic skip loader, tailored to the customer’s specific component containers.

                                     The discharged pieces fall onto vibratory or belt unload channel conveyor and are transported to the next operation. The GG shot blasting machine’s housing is protected by wear-resistant manganese steel liners.

SAND DRYERS

Discription:

The supply of sand often contains moisture (unless dried sand is purchased) which is more than what may be used in foundry, especially for core making or for chemically bonded sand system. Therefore, the supplied sand needs to be dried to a known moisture content. Since during drying the sand becomes hot, the same often needs Coolers also so that it can used in the process without without delay.

 Sand Drying & Cooling plant complete with equipment for handling and storing of dried and cooled sand. These plants are available from capacities of 3 TPH to 50 TPH. Wesman also supplies individual Dryer and Cooler of smaller sizes – from 200 kg to 5 MT per hour.

If customer prefers we also make and supply customized Rotary Drum drye and Fluidized bed dryer .

When air or gas is passed through a bed of particulate solid material, at a particular range of velocity, the solid bed gets converted into Gas-Solid mixture, expands and the particles move within the bed. At this velocity range the dispersed solid particles acquire many of the properties of a fluid and is said to be in FLUIDISED state. In fluidized state intimate contact between hot gas and solids at high relative velocity enhances heat transfer rates. Thus higher efficiency is obtained due to fluidization. About 30 to 40 % fuel saving is possible in case of Fludised bed dryer compared to Rotary dryer.

Hot air / gas is supplied at a specific pressure in the pressure chamber from which it flows through the distribution plate to the container having the bed of sand to be dried. Hot air may be supplied from oil / gas fired Hot Air Generator (HAG) or an Electric Air Heater. The HAG / Air Heater have been specially designed to operate at relatively high back pressure.
