EQUIPMENT EXPLAINED

JAW CRUSHER VS CONE CRUSHER

They are both crushers, but they perform different jobs in the crushing circuit.

🪨 JAW CRUSHER

PRIMARY CRUSHING

A jaw crusher uses a fixed jaw and moving jaw to compress large feed material.

Best suited to:

Large blasted rock

Large boulders

Primary crushing

Quarry start-up operations

Producing material for secondary crushing

THE PRINCIPLE

FEED → COMPRESS → BREAK → DISCHARGE

Think of the jaw as the front door of the crushing plant.

⚙️ CONE CRUSHER

SECONDARY / TERTIARY CRUSHING

A cone crusher uses a rotating mantle inside a concave to continuously compress and crush material.

Best suited to:

Pre-crushed rock

Secondary crushing

Tighter product sizes

Higher-volume aggregate production

Producing more controlled aggregate shapes and gradations

THE PRINCIPLE

FEED → COMPRESS → CRUSH → CLASSIFY

Think of the cone as the refining stage.

SO WHICH ONE?

Don't ask:

“Which crusher is better?”

Ask:

“What material are we feeding, and what product do we need?”

Consider:

FEED SIZE
How large is the rock entering the machine?

PRODUCT SIZE
What size aggregate are you trying to produce?

PRODUCTION RATE
How many tonnes per hour do you need?

MATERIAL CHARACTERISTICS
What are the rock's hardness, abrasiveness and moisture conditions?

CRUSHING CIRCUIT
Is this primary crushing or secondary/tertiary crushing?

THE ORVISTONE RULE

BIG ROCK STARTS WITH THE JAW.

THE CONE REFINES THE PRODUCT.

The right crushing circuit begins with the rock, the required product and the production target.

BREAKER VS ROCK SPLITTER

They both break rock. They do it very differently.

🔨 HYDRAULIC BREAKER

A breaker delivers repeated impact energy through a tool mounted to an excavator or other carrier.

Best suited to:

• Breaking concrete and hard rock
• Reducing large boulders
• Excavation and trenching
• Road and civil works
• Production where rapid breaking is required

The principle:
IMPACT → FRACTURE → REDUCE

🪨 HYDRAULIC ROCK SPLITTER

A hydraulic splitter uses controlled expansion inside a prepared hole to generate splitting force within the rock.

Best suited to:

• Large granite boulders
• Rock close to structures
• Foundations and confined sites
• Sensitive areas where controlled breaking is important
• Situations where reducing vibration is a priority

The principle:
DRILL → SPLIT → REMOVE

SO WHICH ONE?

There is no universal winner.

The right method depends on:

ROCK TYPE
BOULDER SIZE
SITE ACCESS
SURROUNDING STRUCTURES
REQUIRED PRODUCTION RATE
VIBRATION CONSTRAINTS
AVAILABLE EQUIPMENT

ORVISTONE RULE

DON'T START WITH THE MACHINE.

Start with the rock and the site.

Then choose the method.

WHAT DOES A 10-BAR COMPRESSOR ACTUALLY POWER?

A compressor's 10 bar rating tells you pressure. It does not tell you how many tools it can run.

That distinction matters.

For pneumatic equipment, you need to consider both pressure and air flow, usually specified as CFM or litres per second. Atlas Copco notes that compressor selection should be based on the tool's actual air requirement and that manufacturer data should be used whenever available.

So what can 10 bar power?

Depending on the compressor's actual air delivery, applications can include:

PNEUMATIC ROCK DRILLS
Handheld surface rock drills can have substantially different air requirements. For example, Atlas Copco lists light drills from around 22 to 24 L/s, while heavier models such as the RH 658 are listed at 58 L/s, with the figures given at their specified operating conditions.

PNEUMATIC HAND TOOLS
Drills, impact tools, grinders and other pneumatic equipment can operate from compressed air, but their consumption varies significantly. Atlas Copco's reference figures, for example, put pneumatic drills around 8–12 CFM and angle grinders around 25–35 CFM at 90 psi.

AIR BLOWING AND CLEANING
Compressed air can also be used for intermittent blow-off and cleaning applications, subject to the equipment's pressure and flow requirements.

HERE'S THE IMPORTANT PART

A 10-bar compressor does not automatically mean "one rock drill."

You need to know:

PRESSURE
Can the compressor maintain the pressure the tool requires?

FLOW
Can it deliver enough air continuously?

DUTY CYCLE
Will the tool operate continuously or intermittently?

HOSE & SYSTEM LOSSES
Can the air system deliver the required flow at the tool?

For example, a heavy pneumatic rock drill may consume far more air than a small handheld drill. Atlas Copco lists some underground pneumatic rock drills at 69–97 L/s at 6 bar, illustrating why compressor sizing cannot be based on pressure alone.

THE ORVISTONE RULE

Don't ask:

"Is it a 10-bar compressor?"

Ask:

"How much air does it deliver, and what tool are we powering?"

That's how you match the compressor to the job.

$30,000 MACHINE. $30,000 PROBLEM.

A contractor has a $30,000 machine sitting in front of him.

He has $8,000 cash.

His first thought:

“I can't afford the machine.”

At OrviStone, we ask a different question:

“Can the machine produce enough income to justify financing it?”

That is the difference between looking at a machine as an expense and looking at it as a productive business asset.

Before financing equipment, look at the numbers:

MACHINE
What will it cost?

WORK
What jobs will it perform?

UTILISATION
How many hours can it realistically work?

OPERATING COSTS
Fuel. Operator. Maintenance. Insurance.

CASH FLOW
What can the machine realistically contribute?

PAYMENT
Can the business comfortably support the finance obligation?

A $30,000 machine does not automatically make sense because it is useful.

It makes sense when there is a credible business case for putting it to work.

That is how we think about equipment leasing at OrviStone.

Don't start with the machine price. Start with the machine's ability to produce.

What machine would you finance if you knew you had enough work for it?

DON’T BUY IT. USE IT.

Not every project needs you to own a machine.

Sometimes you need an excavator for a few days. A crusher for a production run. A loader to move material. A compactor to finish the job.

OrviStone Equipment Leasing gives you access to the equipment your project needs, without the permanent cost of owning every machine.

THE MACHINE MUST PAY FOR ITSELF.

You do not need another machine sitting in your yard.

You need a machine making money.

For a contractor, farmer, quarry operator or equipment entrepreneur, the question is not simply:

“Can I afford the machine?”

Ask:

What work will this machine do?
How many hours will it work?
What will it earn?
What will it cost to operate?
Can the cash flow support the payment?

The model is simple:

MACHINE
↓
WORK
↓
CASH FLOW
↓
PAYMENT

That is the thinking behind OrviStone Equipment Leasing.

We are developing equipment finance solutions for productive machinery, from compactors and generators to excavators, backhoes, crushers and agricultural equipment.

The machine should have a business case before it has a finance agreement.

What machine would change your business if you could put it to work this month?

ORVISTONE EQUIPMENT LEASING MAGAZINE

THE ZIMBABWE EQUIPMENT FINANCE ISSUE

Buying equipment is easy to think about as a price.

But serious contractors need to think about something else:

CAN THE BUSINESS SUPPORT THE MACHINE?

A US$50,000 excavator is not automatically a good investment because the excavator is worth US$50,000.

The real questions are:

🔹 What work will it do?
🔹 How many hours will it work?
🔹 What can it realistically earn?
🔹 What will fuel cost?
🔹 What will maintenance cost?
🔹 What happens when the machine is idle?
🔹 Can the cashflow support the payment?
🔹 What will the machine be worth at the end of the lease?
🔹 How will the asset be protected and monitored?
🔹 What happens if the customer experiences financial difficulty?

That is why the new OrviStone Equipment Leasing Magazine goes beyond the usual “easy equipment finance” message.

Inside, we examine:

EQUIPMENT SELECTION
Choose the machine around the work, not the other way around.

DEPOSITS & LEASE PRICING
Understand how the financed amount and total contract economics are built.

CASHFLOW
Revenue is not profit. The machine must generate enough operating cashflow to support its financing costs.

MAINTENANCE & INSURANCE
A financed machine that cannot work is a financial problem.

GPS & TELEMATICS
Know where the asset is, how it is being used and when it needs attention.

CUSTOMER SITE ASSESSMENT
Go and see the machine's future workplace before making the decision.

DEFAULT MANAGEMENT
A temporary cashflow problem, structural business failure, asset misuse and fraud are different problems and require different responses.

EQUIPMENT INSPECTION
CONDITION IS DATA.

Record the machine before delivery. Inspect it during the lease. Compare handover condition with return condition. Build a photographic asset record.

And ultimately:

FINANCE THE WORK.

NOT JUST THE MACHINE.

This is equipment finance designed around machines, money and productive work in Zimbabwe.

THE MACHINE MUST PAY FOR ITSELF. 🇿🇼

Something different is coming from OrviStone Equipment & Tools.

We are building a special edition magazine specifically for the Zimbabwean equipment market.

Not another brochure.

Not another article saying, “leasing makes equipment affordable.”

This magazine asks a much more important question:

CAN THE MACHINE PAY FOR ITSELF?

A US$50,000 machine means very little if it spends most of its time parked.

What matters is:

WHAT WORK WILL IT DO?
HOW MUCH CAN IT PRODUCE?
WHAT WILL IT COST TO OPERATE?
HOW OFTEN WILL IT WORK?
CAN THE CASHFLOW SUPPORT THE PAYMENT?
WHAT WILL THE MACHINE BE WORTH LATER?

Inside the coming OrviStone Equipment Leasing Issue, we will examine:

🔸 Equipment selection
🔸 Deposits
🔸 Weekly vs monthly payments
🔸 Cashflow
🔸 Credit assessment
🔸 Lease pricing
🔸 Residual value
🔸 Maintenance reserves
🔸 Insurance
🔸 GPS and telematics
🔸 Default management
🔸 Equipment inspections
🔸 Site assessments
🔸 Equipment profitability
🔸 Lease applications
🔸 Lease approval
🔸 Handover procedures
🔸 End-of-lease options
🔸 Remarketing and resale

And most importantly:

WE WILL LOOK AT THE ECONOMICS OF THE MACHINE.

Because the question should not simply be:

“How much can I borrow?”

It should be:

“What machine can my business actually support?”

This is the philosophy behind OrviStone Equipment Leasing.

EQUIPMENT IS THE TOOL.

PRODUCTIVITY IS THE GOAL.
