The belt width is 1200mm (4’) and a heavy duty 3 ply belt is fitted.

 

 

Twin Shaft Continuous Mixer

  • Mixing Action: The twin shafts mix the material while moving the material toward the end of the mixer.
  • Paddles: The twin horizontal mixing shafts are fitted with alluminated cast steel paddles, which are intermeshed in a specially phased relationship to optimize mixing action while maximizing throughput.
  • Cleaning and Maintenance Access: Special attention has been paid to give the user maximum access for maintenance and cleaning operations. The top of the mixer is fitted with hinged access covers, which when opened give access to all of the mixing chamber. Both sides of the mixing chamber hinge down, to give access, the sides are lowered by hydraulic cylinders.
  • Drive: The shafts are driven by (2) 55 kW (75 HP) electric motors through reduction gearboxes with twin gears to synchronise the shafts.
  • Mixing Chamber: The mixing chamber is formed by fabricated sloped sides with a troughed conveyor under the mixer forming the bottom of the mixer.
  • Water Addition: Water spray bars fitted into the top of the mixer allow the water to be added to the material as it progresses along the mixer.
  • Clean-out conveyor: Mounted on the bottom of the mixer, forming the bottom of the mixing chamber, this conveyor allows the bottom of the mixer to be easily cleaned out, when production is finished. The mixer should be lined with a bed of material every morning before production starts. The conveyor is fitted with a low speed geared motor drive.

 

Cement / Binder Silo

  • Construction: Square silo design constructed from all welded box section S275 plate with stiffening ribs.
  • Access to Roof: The folding access ladder with safety cage is fitted with double tubular handrail and a kicking strip. An access hatch is provided on top of the silo.
  • Outlet: Flanged to suit the rotary valve paddle feeder. A shut-off plate is provided to close the silo outlet to allow maintenance to the feeder below.
  • Silo Venting: 20m2 Reverse Jet Filter with fan assistance. A pressure relief valve is fitted to protect the silo from over-pressurization.
  • Filling Pipes: (2) 4” (100mm) steel pipes with screwed end for fitting cam locks or other type of delivery hose fitting.
  • Level Indication: Rotating paddle style level probes for high and low level control.

 

Cement Paddle Feeder

  • Type: 750mm (30”) square rotary valve paddle feeder to feed the cement or binder material out of the silo.
  • Drive: 2.2 kW (3 HP) geared electric motor with automatic variable speed control.

Out-Loading Conveyor

  • Function: Transporting the mixed material from the twin-shaft mixer to the truck. The conveyor is designed to handle the maximum feed-rate from the mixer. A Gob hopper fitted to the top end of the conveyor allows some mixed material to be “held” for a while, for example, while the next truck drives under for collection.
  • Construction: Boxed steel construction with mounting brackets for rollers and pivot mechanism. The top section of the conveyor incorporates a folding section for transportation.
  • Belt: 1000mm (39.4”) 3 ply belt with heavy duty top cover and vulcanized joint.
  • Drive: Motorized drum with rubber lagging.
  • Belt Scraper: Polyurethane blade pre-cleaner scraper mounted on the face of the head drum.
  • Belt Scale: A belt scale is fitted to this conveyor to monitor and control the feed rate and hence output of the plant.
  • Gob Hopper: Hopper fitted to the top end of the conveyor with pneumatic discharge doors to prevent segregation. Constructed from S275 plate.

Systems

WATER SYSTEM

  • Water Tank: A 1750 liter (462 us gal.) is fitted complete with automatic shut off valve and galvanized steel piping.
  • Pumps: Two positive displacement pumps are fitted to supply 2 water spray bars within the mixer.

  • Out loading conveyor
  • Aggregate conveyor
  • Silo feeder
  • Water pumps
  • Mixer clean out conveyor
  • Silo filter fan unit
  • Internal lighting
  • External lighting
  • Gob hopper doors
  • Auxiliary feeder (e.g.: 2nd silo or any additional raw material)
  • High silo alarm
  • Low silo alarm
  • Low water alarm
  • Alarm mute button
  • Emergency stop and reset button
  • Panel live indicator
  • Generator remote start switch

The operator control panel also houses the following:

  1. Siemens or Allen Bradley operator interface allows the operator to store, edit and retrieve up to 100 recipes for the proportioning of different materials. This touch screen has the facility to archive various production information, e.g.: current stock levels, production records etc. These can be tailored to suit the customer requirements. The operator panel can handle multiple languages. (Required languages should be specified at time of order.)
  2. Manual rate meters which display the speed of the in feeds during manual operation.
  3. Mixer amp meter to display the current being consumed during manual or automatic operation of the plant.
  4. A thermal printer for printing batch and daily total tickets.

Starter Panels: There are 2 starter panels. Panel 1 for mixer and Panel 2 for all other functions.

  • Panel 1 is located behind the mixer and houses the contactors, overload relays, timers and current transformers required to start and run the mixer motor using a star / delta sequence.
  • Panel 2 is located under the operator control panel and houses all contactors, overload relays, MCB’s, Siemens or Emerson inverters, Siemens or Allen Bradley and all other components required to control the plant.
