Mobile crushing plant assembled in Arequipa, Peru for building stone production

In 2026, a new mobile crushing and screening plant supplied by HAMAC arrived at a quarry near Arequipa, Peru, and has been assembled on site to start producing crushed stone for local building projects. The mobile unit was delivered in several transport modules and then re‑assembled by HAMAC engineers together with the client’s team, forming a compact production line that can move close to the rock face and supply high‑quality stone for concrete and masonry works in the Arequipa region. For the contractor, this solution reduces the need to haul raw rock over long distances and ensures a stable supply of building aggregate directly at the construction area.

The mobile crushing plant integrates feeding, primary crushing, secondary crushing and screening on a single chassis, functioning as a complete stone processing line for construction use. The system typically consists of a vibrating feeder that transfers material to a jaw crusher for primary breaking, followed by a cone or impact crusher for secondary reduction, and a multi‑deck vibrating screen to separate different aggregate sizes. Crushed stone fractions are discharged by belt conveyors into stockpiles that can be loaded into dump trucks and transported to concrete batching plants, block factories and building sites around Arequipa. By bringing the production line directly to the site, the client shortens installation time and starts stone production shortly after the equipment arrives.

At this Arequipa job site, the mobile plant is mainly used to produce graded stone for structural concrete, block making and general building works. The quarry rock is fed into the primary crusher, where large stones are reduced to smaller sizes suitable for further processing. The screening unit separates the material into several size ranges, such as base course, sub‑base and fine aggregate for concrete, so local builders can choose the right stone fraction for foundations, columns, beams and slabs. Producing these stone sizes on site improves quality control and reduces dependence on outside aggregate suppliers.

The mobility of the plant is especially important in the mountainous terrain around Arequipa. The equipment can be repositioned as the quarry face advances or moved to different borrow pits, so stone is always produced close to where it will be used. Compared with a traditional stationary crushing installation that requires heavy civil foundations and long fixed conveyors, the mobile crusher plant can be set up more quickly and relocated without major civil works, which suits the dynamic and scattered nature of building projects in this region. Thanks to this flexibility, the contractor can respond faster to new construction sites while keeping investment and operating costs under control.

HAMAC provided the complete solution for this Arequipa project, including layout drawings, installation guidance and on‑site commissioning support. After mechanical and electrical tests confirmed that the mobile crushing and screening plant achieved the required capacity and stone gradation, the client started regular operation, supplying crushed stone to housing developments, commercial buildings and infrastructure works in and around Arequipa. With this mobile crushing plant, HAMAC continues to support Peruvian contractors with reliable equipment for producing construction aggregate directly at the jobsite.
