How are cement and concrete made?

Cement is the main ingredient in concrete and consists of a fine powder that when mixed with water, sand, and aggregate forms concrete.

But how is cement created? It is manufactured by heating a mixture of limestone, clay, and sand into a rotating kiln at high temperatures (2640°F / 1450°C) to produce a cement “clinker.” Clinker is then cooled and ground into a fine powder, at which point it becomes cement.

Concrete is then formed by mixing cement (7-10%) with a mixture of sand and gravel (fine & coarse aggregate) and water to form a concrete slurry.

How do peristaltic concrete pumps work?

Also known as hose pumps, peristaltic pumps have been used for approximately 150 years since the late 1800s, when they were used to transfer mortar and plaster inside of buildings during construction. Hose pumps were classified as a heavy duty piece of equipment, ideal for slurry or solids handling. Since then, advanced capabilities have expanded for hose pumps as peristaltic technology has improved.

In peristaltic concrete pumps, the rollers or shoes move cement slurry through the hose or tube at high pressure, so there is no need for degassing valves. The rollers squeeze the concrete to prevent backflow, removing the need for mechanical seals, creating a seal-less system.

The rollers compress the hose and eliminate internal backflow through the pump. They work similarly to a rotary pinch valve with ±1% repeatability. The movement of the roller or shoe rotation controls the direction of the cement slurry flow, with no internal valves needed.

Typical peristaltic concrete pump applications in the cement and concrete industry

  • Cement slurry transfer
  • Production of chemical additives such as: ·
    • Flocculent, coagulant, color enhancers, strengtheners
    • Accelerant to reduce dry time inside burner during production
  • Wastewater or cleanout such as:
    • Dewatering (filter press)
    • Truck washout containing sand, silt, sediment
    • Granite cutting, stone fabrication, and glass cutting
  • Filter press applications
  • Concrete coloring or batching
  • 3D printing using mortar or concrete

Peristaltic concrete pumps by Albin Pumps

Why choose Albin Pump peristaltic concrete pumps for your cement and concrete needs?

  • Peristaltic concrete pumps function using a simple working principle.
  • Peristaltic concrete pumps have fewer mechanical parts than other pump technologies, decreasing the service required for worn parts.
  • The rollers or shoes rotate to compress the hose to move the slurry.
  • Fluid does not touch any part of the pump, except the inner surface of the hose or tube and connector.
  • Our hose pumps are able to self-prime or dry prime, which prevents off-gassing lock-ups that may occur with sodium hypochlorite applications.
  • Our peristaltic concrete pumps can run dry without causing harm to the pump or hose.
  • Our portfolio has a wide range of hose and tube materials available to ensure chemical resistance.
  • Albin Pump hoses and tubes have excellent chemical resistance and abrasion resistance to lime milk or lime slurry.
  • Hose pumps are great for shear-sensitive fluids, such as polymers. They can gently transfer products without damaging the structure (polymer chains, for example).
  • Reduced hose wear: Our natural rubber hose is highly resistant to abrasion and has a longer hose life, resulting in less service needed.
  • Easy and fast maintenance: Scheduled service consists of a simple hose change-out, yielding a lower total cost of ownership.
  • Dosing applications typically use integrated Variable Speed Drives (VSD) and/or customer PLC to control the flow rate more accurately than with a fixed-speed drive.
  • Flow can occur in either direction through the hose. This bi-directional flow enables a user to easily clean the hose by flushing the lines and the process piping system.
