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 conveyorsapplied 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.

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.

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.

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 conveyorsapplied 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.

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.

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.

These specifications apply to centrifugal discharge type belt and bucket elevators incorporation rubber and cotton/nylon fabric belting for handling foundry sand.
