Parker Plant introduce the ConStar 750C and ConStar 1500 mixing plants

With increasing demand for concrete in many world markets, Parker Plant have recently extended their existing concrete plant portfolio with two new models, both designed to offer increased mobility and ease of transport. The ConStar 750C is a 30m3/h plant which can be transported or stored between contracts in a single 12m (40ft) open-top container, while the larger, fully mobile, equipped ConStar 1500 is a 50m3/h plant with a Teka pan mixer and 35m3 of on-board cement storage. Both units were exhibited for the first time at Hillhead 2012, where many visitors commented on their ease of operation and transport, and their overall accessibility for maintenance.

With a production capacity of 30m3/h and a fully automatic, PLC-based control system with multi-recipe capability for all concrete mixes, the ConStar 750C meets the requirements for small- to medium-sized projects where there is a need for high-quality ready-mixed or precast concrete. The factory pre-wired plant requires minimal site preparation and can be installed and operational within 4h.

The plant features a four-compartment aggregate feed hopper. Each compartment can hold up to 7.5m3 of material and two are equipped with vibrators to prevent the build-up of fines. Aggregates are weighed in a two-speed skip and delivered to the mixer via an inclined track with a 9.5kW skip winch. This method eliminates the need for a weigh conveyor and results in less wear at the discharge points and reduced spillage. The plant also features a 300kg capacity cement weigh hopper and a 250kg capacity water weigh hopper.

Offering 750-litre dry-mix and twin-shaft pan mixer options, the ConStar 750C mixer is equipped with a 22kW drive, abrasion-resistant liner plates, spring-loaded paddle arms and adjustable tips. Ample access is provided to the plant’s mixer level via maintenance platforms that can be easily removed for transport. When folded for containerization, the plant measures 11.5m in length, 2.1m in width and 2.3m in height.

The fully mobile road-towable ConStar 1500 has a four-compartment feed hopper with each compartment capable of holding up to 11m3 of material. Aggregates are weighed on a 4.15m long x  800mm wide troughed weigh conveyor (1.5m3 volumetric weighing capacity of from all four compartments) before being transferred to the mixer via a 10.3m long x 800mm wide inclined chevron belt conveyor powered by an 11kW drive.

An integral chassis-mounted 35m3 capacity cement silo is mounted above the transfer conveyor and features two discharge troughs, each fitted with high and low level indicators. Cement is delivered from the silo to two 350kg capacity weigh hoppers via a pair of retractable discharge/delivery screws. Water addition is via a two-stage delivery system and 300kg capacity weigh hopper.

High-quality mixing is ensured by the plant’s 1,500-litre capacity Teka pan mixer, which is powered by a 37kW mixer drive and features abrasion-resistant liner plates, spring-loaded paddle arms and angle-adjustable tips. 

Semi-trailer towing is easily achieved as the plant’s 2.4m x 1.5m control cabin hinges upwards and into the main structure for transportation purposes. When folded for transport, the plant measures 6.9m in length, 3.0m in width and 4.0m in height.
