Quarrying
the underflow from the trash screen, and the underflow from the part rinsing screen are captured in this sump tank, then this dirty water is pumped back to the AggreSandTM 206 sand plant for maximum recovery of sand and efficient use of water.
Sand Fit For A Castle
Using the AggreSandTM 200tph 2-grade sand plant gives the customer maximum control and flexibility in managing the fine sand fraction in the final C33 product while offering the option to make a dedicated in-spec fine sand.
As standard, the AggreSandTM provides the functionality to
blend the fine and coarse sand product at the cyclone discharge point, or at the end of the dewatering screen, at the final product discharge chute. In addition to this a third blending opportunity is created via a specially designed rubber-lined catchbox, under the rinsing screen which allows individually operated adjustable division plates to blend more fines into the coarse product or alternatively maximize the bottom deck area availability for the fine sand production.
Cutting Edge Control System
The on-board HMI control system for this AggreSandTM 206 & AggreScrubTM 150 wash plant is another example of the seamless integration possible with these two plants. Each plant has a dedicated control panel, which is prewired and factory tested. However, when combined the entire plant can be operated and monitored from one single HMI.
For McGuires Excavating & Trucking Inc. the additional feature of having a second HMI located in plant side operator cabin, allows the operator to monitor plant parameters such as water flow rate and pressure, cyclone pressure and motor running information from one location.
Ryan went on to say: “It has given us a great deal of flexibility in the market. We started here with a much smaller washing plant and after looking at the market and the changes, we opted for this solution which has allowed for
more flexibility to better serve the market and demands. It’s modular in design, so we can change the modules and we also have the ability to add a larger sand plant if the market changes. Moreover, on the back of that we have built a strong relationship with our local dealer, Powerscreen Crushing and Screening, as well as with TWS. The fantastic thing about the AggreSand TM is the modular design, allowing us to be flexible and fast in the market and it allows us to react quickly. From start to finish, from the product coming in, the assembly of the build, commissioning, everything has been flawless.’
