Weigh Batcher

Batcher | Standard 

0.35 meters to 14 meters, custom designed & manufactured to customer specifications

Features:

• heavy duty 1/4" steel construction with external stiffeners & internal stays
• high degree slopes to promote smooth material flow 
• smooth operating, heavy duty CMC discharge gate with replaceable cast gear segments, grease fittings & shoulder bolts
• single air cylinder operation (two cylinder on larger sizes)
• vibrator mounting bracket

Additional Options:

• AR steel construction or wear plates available

 

Batcher | Live bottom

Many precast concrete batch plants use live bottom-weigh hoppers.  The belt on a live bottom batcher is stationary when weighing aggregates. This type of belt is designed to be started under load to move the weighed aggregates to a transfer belt, hopper or skip hoist. 


The advantage of a live bottom batcher is that another batch can be weighed and waiting to go into the mxer, bucket elevator or skip hoist immediately after the previous batch is discharged. This saves time and can increase output.

Features:

• heavy duty construction
• return rollers to prevent belt sag and drag
• internal baffles in the batcher to reduce the weight of material on the conveyor belt for longer motor life
• floor supports allow for easy clean-out under the batcher
• heavy duty 330 Series belting (3/16" x 1/16")
• vulcanized splice available
• dependable NTEP certified 'S' type load cells
• heavy duty hanging hardware and safety rods

 

Auxiliary Weigh Scale 
​
System eliminates need to:

• drain bin & slow down production for partial material load 
• costly clean out to prevent contamination of a specialty aggregate with standard aggregates

Features:

• holds over 20 tonne of regular weight aggregate
• can be filled with single axle truck or front end loader
• elevated to allow a truck to back under to load
• remote digital read out
• heavy duty 'S' - type NTEP certified load cells
• heavy duty hanging hardware and high tensile safety rods
• can weigh cumulatively or decumulatively
• can be operated from bin base or inside batch office
