Many manufacturing processes require product in sacks to be discharged at the infeed point. Powder products have their own set of handling problems, dust containment being high on the list. The COSHH Regulations require employers/business owners to provide a dust-free environment for their process operators to work in. The handling of powders, flakes, pellets etc can be one of the most time consuming, labour intensive and hazardous processes in industry. Thousands of people are affected each year resulting in illnesses as serious as lung disease and cancer. It is important that efficient solutions are made available to combat suffering and also the high economic costs relating to occupational ill health.
For over 25 years Palamatic has been at the forefront of designing sack opening machinery to suit a variety of process related operations. The main objectives of Palamatic’s range of machines is to maximise product retrieval, ensure good house-keeping and help businesses comply with the COSHH Regulations. Once opened the product leaves the machine outlet into onward processing such as into collection hoppers, vibratory screens, screw or aero mechanical conveyors.
As no two manufacturing processes are the same and with individual site plan restrictions to take account for Palamatic has developed a range of machines.
This is one of Palamatic’s long standing solutions for automatic sack opening and also is one of the most cost effective options. The principle of design has been proved over many years of reliable performance throughout many industries. The MiniSlit is based on a continuous cyclic sequence of operation with electro pneumatically powered sack opening functions making it ideal for operations requiring 4-8 sacks per minute.
The MiniSlit has a small foot print and due to its principle of operation is most suitable for free flowing and lightly compacted materials in sacks.
The MiniSlit can be supplied with the options of a horizontal infeed roller conveyor for manual feeding of the machine or with a powered inclined conveyor.
The band knife cutting blade utilised on the MiniSlit achieves a very efficient cut and emptying operation of the product from the sack or bag. As the sack is being conveyed through the blade system a clean cut is made through its length and then retracted leaving the end of the sack uncut. The bottom and the top halves of the sack are transferred via inverter discs in a continuous operation into the waste sack screw compactor where the secondary discharge of product can take place as the sack is collected and then compacted out into the dust tight polythene tube attached to the compactor outlet.
A dust extraction spigot or an integral dust extraction unit is available to ensure maximum dust tight operation. The MiniSlit can be supplied to operate to operate in various ATEX zones and where material is of an explosive relief panels or explosive suppression equipment.
The MiniSlit offers many machine finishes from the mild steel powder coated to various levels of stainless steel finishes polished to 240 grit which makes it suitable for high specification applications. The MiniSlit can be supplied fully wired to a machine mounted terminal box. An optional control panel can be supplied loose for mounting as required where the customers prefer to integrate controls into their own factory systems. Palamatic can supply any necessary Functional Design Specification for such integration.
