The Monitor Technologies SiloPatrol® smart cable-based sensor system with 4-20mA output was being used successfully on this difficult application at the Luzenac plant in Sappington, Montana. The Three Forks plant needed a solution and decided to try the SiloPatrol inventory monitoring system to reliably keep track of their finished goods inventory. In this tough application the SiloPatrol proved to be the best solution. The sensor is unaffected by the dust and internal bin structures. The SiloPatrol sensor uses a powerful direct drive motor and 270lb. tensile strength cable along with state-of-the-art microcontroller based electronics.

In this application, the customer specified Halar coating over other liner options due to past success with this product on chutes and other equipment they have in service. The customer requested an epoxy coated air cylinder to protect from corrosiveness as it is a more economical option and requires a shorter lead time than a stainless steel air cylinder.

A major plastics thermoformer, whose operations include sheet extrusion and calendering, installed 20 screen classifying cutters from Munson Machinery Co. Inc., Utica, NY, to assure efficient granulation and sizing of its process scrap. It is essential that the cutters work to full capacity during production runs and deliver properly-sized granulate for processing. The company specified Munson’s SCC model cutters to replace units from another supplier, which had maintenance problems caused by frequent blade changes, and which could not process trim scrap at desired production rates.

The Munson blenders have a working volumetric capacity of 225 cubic feet (6.37 cubic meters). Carmichael says paddles were specified because they can be easily cleaned, since their design yields less surface area than other mixing elements. Fast cleaning reduces downtime during product changeover. It also means workers usually have no need to enter the blenders when cleaning them, which reduces the regulatory liability of the company.

Melsur Corporation, the world’s leading supplier of hard plastic melamine school furniture, molds components from a mixture of resin, wood flour and pigments. Each of the 32 color variations, 30 products and custom designs must be blended individually, a process that can take up to four hours, depending on product. Anything less than empirically defined cycle times alters the final color and produces blemishes in the finished product.
The basic mixing process stimulates the absorption of peroxides by pelletized, thermoplastic polymers one-eighth of an inch (3.175 mm) in size. The peroxides act as curatives that give the polymers the ability to crosslink and become thermosetting. “As for the polymers, we use elastomers, polyolefins, and silicones, but mainly polyolefin-based materials,” Johnston says. “Generally the resin must absorb from one to about three percent of its weight in peroxide, which sometimes requires pre-heating of the pellets. In addition,” he continues, “the R&D department is looking at antioxidants that are liquid at room temperature.” Antioxidants can extend the lifetimes of the final materials and improve their electrical properties.

The selection of a polyolefin for a particular application depends on the resin’s type and grade, which are determined by the manufacturing technology or process, the catalyst, and the raw feedstock used in production. In turn, the polyolefin grade is determined by key properties such as molecular weight, molecular weight distribution (MWD), crystallinity, branching and density that affect how and where each resin is used. Two distinctive process sections can be identified in polyolefin production, a wet-end and adry-end process.
