A three-roll rolling mill is used to process various products, from pastas to pharmaceuticals. It has three rollers that rotate at increasing speeds and can be equipped with heating and cooling. The device can be rented, leased, or bought new or used. Safety precautions should be taken when operating the mill.
A three-roll rolling mill is an industrial piece of equipment used to process pastas to a uniform consistency. Three mills are available in a range of sizes, from benchtop versions for science labs to industrial models capable of producing very high volumes that can fill half a room in a factory. Manufacturers of these products typically have a number of size options and may include various features with their equipment to make it more versatile and appealing to potential customers.
The design includes three rollers that rotate at increasing speeds and in opposite directions. As an operator feeds the materials, they are forced through the series of rollers until they reach the end, where a blade scrapes off the finished paste. The three-roll mill can be equipped with roll heating and cooling if needed for the process, along with other features such as adjustable rolls for different materials and electronic programs that can be preset for common jobs.
A wide variety of products can be processed through a three roll mill including paints, pigments, plasters and pharmaceuticals. Pulps are used in the manufacture of a range of finished products such as electronics and foods and a reliable mill can be important for quality control. In addition to grinding products into a uniform paste, the device also expels air, which can be useful for some forms of industrial production, where air pockets may not be desirable.
Technicians at a three-roll mill can adjust various settings for different components and can use covers and other equipment to limit contamination during processing. Like other industrial equipment, these devices can be potentially dangerous. An emergency stop button is usually provided and workers may need to watch out for hair and clothing that could get caught in the rolls if they are not careful.
There are options for renting, leasing and buying three rolling mills. If a company has a temporary need, they may be able to arrange a rental or they may contract with another company to produce a paste to specific specifications. It is also possible to rent or buy used equipment if the cost of a new mill is prohibitive. Another option for a low-cost purchase may be a liquidation or surplus sale, where a mill in good condition may be available at a low price to ensure it sells as quickly as possible.
