Crown Cement Mixer: Complete Guide to Crown Concrete Mixers, Models, Sizes, Features, and Uses

A Crown cement mixer is a professional concrete mixing machine designed for contractors, masons, landscapers, rental companies, and construction crews that need reliable on-site concrete production. Often searched for as a Crown concrete mixer, these machines combine heavy-duty drums, rugged frames, dependable drive systems, and multiple capacity options for everything from smaller construction projects to demanding commercial concrete work.

Crown Construction Equipment offers several concrete mixer configurations, including the compact Max Mix series and larger C6, C9, C9P, and C12 models. The larger towable mixers are designed for professional jobsite use and are available in capacities ranging from approximately 7 to 12 cubic feet depending on the model.

Choosing the right Crown cement mixer depends on how much concrete you need to produce, your preferred power source, towing requirements, drum material, and the size of your typical concrete pours.

What Is a Crown Cement Mixer?

A Crown cement mixer is a rotating-drum machine used to combine cement, aggregates, sand, and water into concrete.

While people frequently use the terms "cement mixer" and "concrete mixer" interchangeably, cement is actually one ingredient used to make concrete. The machine itself mixes all of the ingredients together, which is why manufacturers generally call these machines concrete mixers.

Crown Construction Equipment produces a range of contractor-oriented concrete mixers, including:

• Max Mix Poly

• Max Mix Steel

• Crown C6

• Crown C9

• Crown C9P

• Crown C12

These models cover everything from portable electric mixing to larger towable machines for professional construction.

Why Choose a Crown Concrete Mixer?

Contractors need mixers that can withstand repeated loading, mixing, dumping, transportation, and cleanup.

Crown's larger concrete mixers incorporate several heavy-duty construction features. Steel-drum models use welded high-abrasion-resistant steel drums. Crown also uses cast-iron drive pinions and gear rings, while its towable concrete mixers feature high-speed tapered roller bearings.

The machines are designed around both mixing performance and jobsite durability.

Depending on the model, additional features include:

• Multi-position drum locking

• Retractable or removable tow poles

• Safety chains

• Rubber torsion suspension

• Vented engine housing

• Swing-away engine hood

• Multiple internal mixing blades

• Heavy-duty frames

These features make Crown mixers particularly attractive for contractors who regularly move equipment between jobsites.

Crown C6 Concrete Mixer

The Crown C6 concrete mixer is one of the smaller professional towable models in the Crown lineup.

The C6 has a rated volume of approximately 7 cubic feet (220 liters) and a batch capacity of approximately 0.5 to 1 bag, depending on the mix.

Power options include gasoline or electric configurations.

The manufacturer lists gasoline power in the 5.5 to 8 HP range or a 1.5 HP Baldor electric motor. Power is transferred through a V-belt-to-gears drive system.

The C6 is approximately:

• 48 inches wide

• 83 inches long with tow pole in

• 58 inches high with drum down

• 790 pounds

The steel drum uses approximately 10-gauge, 1/8-inch material.

The C6 is a strong option for contractors who need professional mixing capacity without moving into one of Crown's largest mixers.

Crown C9 Concrete Mixer

The Crown C9 increases capacity for contractors handling larger batches.

The C9 provides approximately 9 cubic feet (260 liters) of capacity with a manufacturer-listed batch capacity of approximately 1 to 1.5 bags.

Power choices include:

• Honda 8 HP gasoline engine

• Baldor 1.5 HP electric motor

Like the C6, it uses a V-belt-to-gears drive system.

Approximate dimensions include:

• 50-inch overall width

• 83-inch overall length with tow pole in

• 63-inch overall height with drum down

The approximate machine weight is 868 pounds.

For contractors regularly mixing concrete throughout the workday, the additional capacity of the C9 can reduce the number of batches required compared with smaller machines.

Crown C9P Concrete Mixer

The Crown C9P provides approximately 9 cubic feet of capacity but uses a polyethylene drum rather than the traditional steel drum.

This configuration can be attractive when easy cleanup is a priority.

The polyethylene drum is designed for durability and reduced concrete adhesion compared with conventional steel surfaces.

Crown's published C9P specifications list:

• 9-cubic-foot capacity

• 1 to 1.5 bag batch capacity

• Honda gasoline or Baldor electric power options

• V-belt-to-gears drive

• Approximately 50-inch width

• Approximately 580-pound weight

The polyethylene drum is approximately 9/16 inch thick.

The C9P also uses a cast-iron tilting pinion and heavy-duty one-piece cast-iron ring gear.

Crown C12 Concrete Mixer

For contractors requiring greater production, the Crown C12 concrete mixer is the largest of the main C-series models.

It provides approximately 12 cubic feet (340 liters) of capacity.

The listed batch capacity is approximately 1.5 to 2 bags.

Power options include:

• Honda 13 HP gasoline engine

• Baldor 2 HP electric motor

The C12 measures approximately:

• 54 inches wide

• 83 inches long with tow pole in

• 69 inches high with drum down

Approximate machine weight is 895 pounds.

Its larger capacity makes the C12 suitable for contractors who regularly produce substantial quantities of concrete and want to reduce the time spent loading individual batches.

Crown C6 vs. C9 vs. C12

Choosing between the Crown C6, C9, and C12 primarily comes down to production requirements.

The C6 provides approximately 7 cubic feet of capacity and is a good fit for smaller professional applications.

The C9 increases capacity to approximately 9 cubic feet and can handle larger batches.

The C12 provides approximately 12 cubic feet and is designed for higher-output jobs.

As mixer capacity increases, so do factors such as:

• Machine weight

• Engine requirements

• Concrete output

• Loading requirements

• Transportation considerations

A contractor should not automatically purchase the largest machine available. The best mixer is the one that matches typical batch requirements and crew productivity.

Crown Max Mix Cement Mixer

Not every contractor needs a large towable machine.

The Crown Max Mix Steel provides a compact alternative.

The Max Mix Steel has approximately:

• 3-cubic-foot mixing capacity

• Steel drum

• 1/2 HP electric motor

• 110V/60Hz electrical requirements

• 23 RPM drum speed

• 110-pound machine weight

It uses an electric motor with a gearbox and a cast-iron gear reducer drive system.

The machine can also function similarly to a wheelbarrow for easier jobsite movement.

This makes the Max Mix useful for:

• Homeowners

• Small contractors

• Repairs

• Small slabs

• Fence posts

• Landscaping

• Patch work

It is substantially more portable than the large C-series towable mixers.

Steel vs. Poly Crown Cement Mixer

One important decision is whether to choose a steel or polyethylene drum.

Steel Drum

Steel drums provide:

• Heavy-duty construction

• Excellent durability

• Traditional professional mixer design

• Resistance to demanding jobsite use

Crown's steel concrete mixer drums use abrasion-resistant steel.

Poly Drum

A polyethylene drum provides:

• Easier cleaning

• Reduced material adhesion

• Corrosion resistance

• Lower weight in certain configurations

The C9P is Crown's major professional polyethylene-drum concrete mixer option.

The better choice depends on how the mixer will be used and maintained.

Gas Crown Cement Mixer

Gasoline-powered Crown mixers provide excellent mobility.

A gas mixer does not require an electrical connection, making it useful for:

• New construction

• Remote jobsites

• Hardscape projects

• Foundation work

• Outdoor concrete placement

Honda gasoline engines are available across multiple Crown concrete mixer models.

The larger the mixer, the more engine power is generally required.

Electric Crown Cement Mixer

Electric Crown mixers can be an excellent option where reliable electrical power is available.

Benefits can include:

• No gasoline storage

• No direct engine exhaust

• Easier starting

• Reduced engine maintenance

• Suitable operation in certain controlled environments

Crown offers electric motor configurations on multiple mixer models.

For example, the C6 and C9 can be configured with 1.5 HP Baldor electric motors, while the C12 can use a 2 HP Baldor electric motor.

Crown Cement Mixer Drum

The drum is the heart of the mixer.

As it rotates, internal blades repeatedly lift and fold the concrete ingredients together.

Crown uses multiple laser-cut steel mixing blades on its professional concrete mixers.

The C6 and C9 use three sets of mixing blades, while the C12 and C9P use six sets.

The objective is to create a fast, consistent, and thorough mixture.

Good internal blade design is particularly important because simply rotating a drum is not enough. The material must be lifted and redistributed throughout the mixing cycle.

Crown Cement Mixer Drive System

Crown's C-series mixers use a V-belt-to-gears drive system.

The drive system transfers engine or motor power to the rotating drum.

Cast-iron drive pinions and gear rings are used for durability.

Proper drive maintenance is important because worn belts, damaged gears, poor alignment, or insufficient maintenance can eventually reduce mixing performance.

Crown Cement Mixer for Contractors

A professional contractor should consider daily output rather than simply purchase price.

A mixer that is too small can create a production bottleneck.

For example, crews may spend too much time:

• Loading

• Mixing

• Dumping

• Reloading

A larger mixer can reduce batch cycles.

However, oversized equipment creates its own disadvantages, including additional weight and transportation requirements.

For small repairs, the Max Mix may be sufficient.

For regular contractor work, the C6 or C9 may offer better productivity.

For larger jobs, the C12 provides substantially greater batch capacity.

Crown Cement Mixer for Concrete Contractors

Concrete contractors can use Crown mixers for:

• Footings

• Small foundations

• Sidewalks

• Curbs

• Equipment pads

• Concrete repairs

• Posts

• Steps

• Small slabs

For very large continuous concrete placements, ready-mix delivery may be more practical.

Jobsite mixers are especially useful when concrete must be produced in controlled quantities over time.

Crown Cement Mixer for Hardscape Contractors

Hardscape and landscape contractors frequently need smaller batches of concrete for:

• Paver edge restraints

• Steps

• Retaining walls

• Footings

• Fence posts

• Outdoor kitchens

• Landscape structures

A towable mixer can move between projects while allowing crews to produce material when needed.

Crown Cement Mixer Parts

Wear components eventually require maintenance or replacement.

Common concrete mixer parts can include:

• V-belts

• Bearings

• Drum components

• Mixing blades

• Pinions

• Ring gears

• Wheels

• Tires

• Engine components

• Hardware

• Tow components

Crown maintains manuals and repair-parts documentation for current C6, C9, C9P, C12, and Max Mix concrete mixers, as well as documentation for several older models.

When ordering parts, identify the exact mixer model and serial information first.

Crown Cement Mixer Maintenance

Routine maintenance helps protect the mixer and reduce jobsite downtime.

Important tasks include:

• Checking engine oil

• Inspecting belts

• Inspecting gears

• Checking fasteners

• Cleaning the drum

• Inspecting tires

• Checking towing equipment

• Inspecting safety chains

• Maintaining the engine

• Checking bearings

Concrete should be removed before it fully hardens.

Allowing hardened material to accumulate inside the drum increases weight and can reduce mixing efficiency.

Cleaning a Crown Cement Mixer

Clean the mixer after each use.

Do not wait until the concrete has completely hardened.

Follow the manufacturer's operating instructions for cleaning.

Crown's current professional concrete mixers use a multi-position drum locking mechanism intended to improve positioning flexibility, including during cleaning.

Never place hands or tools inside a moving drum.

Disconnect or shut down the power source before performing maintenance.

Towing a Crown Cement Mixer

Many larger Crown mixers are designed as towable construction equipment.

Features include:

• Safety chains

• Retractable or removable tow poles

• Rubber torsion suspension

• High-speed tapered roller bearings

However, equipment configuration, local regulations, towing speed, tow vehicle requirements, hitch setup, tires, and machine condition must all be verified before road transportation.

Never assume a mixer can be highway-towed simply because it has wheels and a tow pole.

Follow the specific model manual and applicable transportation laws.
