CASM helps firms get a boost out of energy savings

Q: What is your product/technology?

The CASM electric cylinder is an energy-efficient electromechanical solution for replacing conventional pneumatic cylinder systems and hydraulic lifts.

Q: How does it work?

The CASM electric cylinder is a linear actuator that only requires energy during movement.  This allows customers to realise an energy use reduction of up to 90% when they replace pneumatic cylinders with electric cylinders. 

Q: Where would it ideally be used?

Around the world in a range of industries, but most intensively within packaging, factory automation, food and beverage and material handling industries such as waste and recycling.

Q: How is it different?

They are far more efficient than the pneumatic alternative. Compressed air is typically a very inefficient way to transmit power and systems often require constant power in order to maintain air pressure, even when the actuators are not moving.

Q: What benefits does it offer?

They are designed to withstand the harshest industrial conditions, such as those encountered within the waste and recycling industries, and obtain a protection class complying with IP54. The units are available in stroke lengths from 10 to 800mm and sizes 32, 40 and 63, according to ISO-15552 pneumatic standards.

Q: Where it has been used?

When an SKF customer Indian Textiles replaced hydraulic lifts in a textile printing machine with two CASM electric cylinders, a decline in energy use estimated to be 7MWh per year was observed.  This reduction translates into a CO2 savings of 5.3 tonnes per year for one machine according to world power grid mix CO2 factor of 0.749 kg CO2e/kWh.  The potential CO2 emission reduction that can be achieved by replacing pneumatic systems for waste and recycling with the CASM is therefore immense when looking at the number of operations around the world.

Q: What about maintenance?

The CASM electric cylinder is virtually maintenance-free, which significantly reduces operational costs.

Q: How is it future-proofed?

CASM electric cylinders are compatible with many motors and can be supplied as a complete linear solution mounted with a motor, or integrated with existing equipment using an adapter to suit your motor type.

Q: Any future applications?

The cylinder continues to be adopted across applications because the flexibility, robustness, accuracy and efficiency of CASM electric cylinders all add up to a highly cost-effective means of providing high-speed, heavy lifting or precision motion in many applications, while producing less contamination and noise than pneumatic cylinders.

Q: Anything else?

The CASM electric cylinder is a product of the SKF BeyondZero portfolio, which has been designed to provide products and solutions that will both improve energy efficiency and support more environmentally friendly energy production.

Indian Textile Engineers is now looking at replacing hydraulic lifts in all its textile printing machines. “The difference between using our old hydraulic lifting system and the SKF CASM is huge when it comes to the environmental savings and impact. We no longer consume 400 litres of hydraulic oil per year,” says Niki Thakore, managing director. “Second, our customers reduce energy usage. With 5,000 machines in India, this means our customers could save around $750,000 dollars per month.”

Trommel fines clampdown sees sales growth

Dig A Crusher says the Government’s clampdown on trommel fines has seen demand for its Max X Tract Density Separator “rocket”.

The separator extracts recyclable materials to generate extra revenue and minimise waste disposal by up to 90%. It can process up to 150 tonnes/hour. The Max X Tract Density Separator is designed to segregate stone, lights, wood ferrous and non ferrous materials from -100mm materials. The separator weighs nine tonnes, is self-contained, and can be incorporated into existing waste handling and extraction streams.

Dig A Crusher says that following the Government’s decision on 18 May to start charging the higher £64 a tonne landfill tax, as opposed to the £2.50 rate, interest has soared. “There has never been any question about the quality of the Max X Tract or its ability to turn trommel waste fines into an additional revenue generator,” says managing director Sean Heron. “But the HMRC decision has totally changed the recycling landscape. Those companies that dismissed the Max X Tract as impressive but unnecessary for their business are now urgently placing orders to avoid this huge disposal cost increase.”

Waste plant to benefit from new machines and contract

Avondale Environmental has just bought three Caterpillar machines including two Cat950 high-lift wheel loaders with high tip buckets as well as a CatM318D excavator with Cat G315B sorting grab.

The equipment was supplied by Finning, which will provide repair and maintenance. They will be used at Avondale’s £20m residual waste processing plant in Polmont, Scotland, that opened in February, which will process around 200,000 tonnes of waste a year.

“Having developed the new site, it was important for us to match the mobile plant and equipment to the overall waste handling process, to ensure the highest productivity levels,” says Avondale operations director Stuart Egan.

Cat’s entrant offers more power and uses less fuel

Replacing JCB’s 456 wheeled loader, the company has launched the 457, which it says offers more power and torque. The machine has a Stage IIIB (Tier 4 Interim) compliant 8.9 litre Cummins engine, and features a high pressure common rail fuel injection system, and exhaust gas recirculation.

The JCB 457 delivers power of 186kW or 250hp - up 16% on the outgoing model. It also has 1,085Nm of torque, which is an increase of 18% on the 456. The new model doesn’t require any supplementary additives to provide high power outputs with low emissions. Diesel particulate filter service intervals are every 5,000 hours in Europe, or 4,500 hours in North America.

The economy mode reduces engine output for lighter duties and means the 457 can deliver fuel savings of up to 6%. It also has a low idle feature and an engine shutdown mode, which kicks in after a pre-determined idle period to save fuel.

Doosan DL420 has improved fuel efficiency

Thomas Armstrong (Aggregates) in Maryport, Cumbria, has just bought two Doosan DL420 wheel loaders from Carlisle-based Lloyd. The machines run for 14500 hours and offer more power than the Doosan Mega 400 generation wheel loaders that they will replace. Doosan says the newer model has a 7% improved efficiency on fuel consumption. The DL420 is being used to load sand onto a screening machine which separates out different grades of gravel and sand. Thomas Armstrong also produces graded limestone, recycled furnace slag and other recycled hardcore gravels.

Greener than tar

A path and cycleway surface that can be dug up and re-laid has been developed using Psyllium seeds. The powdered husks are more commonly used as a health supplemen to increase dietary fibre and alleviate digestive problems, but a company in Arizona has experimented with using it as a binding agent.

US firm Stablizer Solutions found that mixed with water the powder husks form a gel that binds aggregate and produces a durable, self-draining and frost proof surface. It also found that a square metre of Psyllium-bound aggregate at 50mm thickness releases just 0.64kg of CO2, compared with 16.69kg for dense bitumen macadam.

North Wales based Stabilizer UK – an enterprise set up by environmental and landscape engineers Richards, Moorehead & Laing (RML) and associates - has secured the deal to market the product in the UK.

“Aggregate bound with Stabilizer is competitive on cost with macadam, has far superior environmental credentials and out-performs it in a wide range of non-highway applications,” says RML managing director Ivor Richards OBE.
