The company made the announcement on Tuesday July 9 after discussions with offtake partners Ganfeng Lithium and General Lithium.
On June 17, Pilbara Minerals said it would reduce output due to delays in the construction of chemical conversion capacity at Ganfeng Lithium and General Lithium.
And on July 9, Pilbara Minerals confirmed that will still shut down its plant for 14 days later in July to undertake work to further improve plant performance.
Despite the delays and shutdowns, Pilbara Minerals achieved a strong performance in the second quarter at its Pilgangoora lithium-tantalum project 120km from Port Hedland in Western Australia.
The company produced 62,334 tonnes of lithium spodumene concentrate min 6% in the quarter, up from 52,196 tonnes in the first quarter of the year.
Shipments were also higher quarter on quarter, with 43,214 tonnes of lithium spodumene moved out in April-June - in line with the company's export guidance of 23,000-45,000 tonnes and up from the 38,562 tonnes shipped in January-March.
Sales for the third quarter are expected to be about 35,000-48,000 tonnes of lithium spodumene, and 65,000-80,000 tonnes in December quarter, Pilbara Minerals said.
The company expects to reach full plant production by October 1, 2019.
