The cumbersome pit structure had been modernised and investment made in new plant. By the end of the 1960s ECC was producing around 2.5m tons of china clay a year. ECC had also expanded into the ball clay market (used in the building industry) and, with over 250,000 tons a year, accounted for nearly half of British output. [1]
The Buell dryer, also known as the "turbo shelf" dryer, is an indirectly-heated industrial dryer once widely used in the Cornwall and Devon china clay mining industry. The Buell dryer was introduced to the china clay industry by English Clays Lovering Pochin & Co. Ltd for their china clay drying plants in Cornwall and Devon, as part of the mechanization and modernization of the industry, which ...
Treffry Estates sold the harbour to English China Clay (ECC) in 1964 having leased it to them since 1946. In the 1950s and 1960s, vast dryers were built on-site. The current Grade Dryer was built in 1996. In 2007 the port and some of the clay dries (those dealing with clay for the paper industry) closed with the loss of 200 jobs.
The route between Par and Fowey closed in October 1968, and was immediately converted to be used as a private haul road for English China Clays (ECC) to carry china clay from the dries at Par to the deep water docks at Fowey. The formation was widened to make a two lane road, and ECC undertook a major modernisation of the handling equipment at ...

For homopolymerization of ECC 1.5 to 3 wt. % of an initiator are added. Above 3 wt% initiator no further acceleration was found, increasing proportions of initiators, however, increase the brittleness of the formed thermoset. After a photopolymerization usually still a thermal post-curing is necessary for a complete reaction. [5]
By the time that English China Clays took over the facilities in 1968 only five jetties remained in use. The main jetty is number 8, while numbers 4 and 6 could load china clay from rail wagons using conveyors. Number 5 only handled bagged china clay from road vehicles and number 3 handled liquid china clay slurry. [1]
