ZCJK announces its China National Day holiday schedule from October 1 to 7, 2026, with work resuming on October 8 (Beijing Time, GMT+8). During the holiday, global customers are welcome to send inquiries about concrete block making machines and complete block production lines. ZCJK will review and process inquiries as soon as possible after the holiday.
ZCJK wishes customers, partners, and friends around the world a Happy Mid-Autumn Festival and shares our 2026 holiday schedule. Our team will be on holiday from September 25 to 27, Beijing Time (UTC+8), and resume work on September 28. During the holiday, customers can still contact us via our official website, WhatsApp, or email for information about block making machines, automatic block production lines, and concrete mixers, and we will respond as soon as possible after the holiday.
Choosing the right concrete mixer capacity is essential for keeping a block making machine supplied with consistent concrete. This guide compares ZCJK’s JW350, JW500, JS500 and JS750 concrete mixers, covering feeding capacity, discharge capacity, rated productivity, stirring speed and typical applications. It also explains how mixer capacity and hourly output are calculated, why JW500 and JS500 can have the same 500 L discharge capacity but very different productivity, and how to match a mixer with your block machine, target output, mix design and future expansion plans. Real ZCJK production configurations and customer project data are also included to help buyers make an informed equipment choice.
