The manufacturer's parameters are generally theoretical capacity. The actual production capacity is affected by the hardness of the material, the uniformity of the feed, the particle size of the output, and the on-site conditions. It is usually lower than the theoretical value. It is recommended to reserve 15%-25% capacity margin to ensure stable production.

The wear parts include the plate hammers, jaw plates, liners, and hammer heads. Their lifespan depends on the wear resistance of the material. High-wear-resistant stone materials have a shorter replacement cycle. Before placing an order, confirm the material of the wear parts, the supply cycle and price of the original factory spare parts to reduce the downtime cost in the future.

Generally, a feeder, a vibrating screen, and a conveyor belt are required; dust-laden working conditions require dust removal equipment; mobile models come with a chassis. If the raw materials contain iron blocks, it is recommended to install an iron remover to prevent hard objects from entering the crushing chamber and damaging the equipment.

The general warranty period for the entire machine is usually 1 year. Wear parts are not covered by the warranty. Regular manufacturers can provide on-site installation and commissioning, as well as operator training. The contract should specify the response time for after-sales services and the terms for on-site services to avoid prolonged downtime due to faults.
