Our take
The Braun KMM 30 / Type 3045 is a household coffee mill with an adjustable fineness ring and a timer/measurer that dispenses a volume-oriented amount. Braun's manual gives starting guidance from very fine coffee through drip, French press and percolator, and describes dishwasher cleaning for the receptacles and lids. A model-matched parts listing calls the bean receptacle 8 oz. The timer does not weigh coffee; burr dimensions/material, measured performance and the row's KMM 30 B / black / ASIN mapping remain unresolved.
For household use where a volume-oriented timer and manual fineness adjustment are acceptable..
Not for commercial duty, built-in gram dosing, a confirmed black variant, or independently verified espresso performance.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The Type 3045 manual documents an adjustable ring and simple timed/measured workflow.
- Its manual gives maker guidance for several home brewing styles.
- The receptacles and lids are described as dishwasher-cleanable, and the parts catalog lists an 8 oz bean receptacle.
What to weigh up
- The timer/measurer is not an integrated scale or verified gram target.
- Burr geometry and material, performance, retention and noise remain unknown.
- The source suffix, black finish and historical ASIN are not crosswalked by the manual.

What the features mean for you
A family-level KMM 30 identity
Braun's Type 3045 instructions establish the KMM 30 family, but they do not map row 171's historical ASIN B00AVCF5D4 to a specific current product. The frozen title's KMM 30 B clue and black description do not prove what the B suffix means or confirm a finish. Keep those details unresolved and verify the badge and rating plate on any offered grinder. A search link can help locate candidates, but it cannot authenticate the old source record or establish availability.
Fineness adjustment and a cup-oriented timer
The manual describes an adjustable fineness ring and an on/off timer/measurer that controls a volume-oriented amount. Its printed advice spans espresso and Turkish-style coffee through drip, hand-drip, French press and percolator. Those ranges are maker setup guidance, not measured grind quality. A general spoon amount in the manual is not a weight-dosing feature. Buyers who need an integrated gram target or a verified dose repeatability figure should plan on a separate scale and should not read a timed run as an exact mass.
Capacity evidence is limited to the bean receptacle
PartSelect's model-matched KMM30 / Type 3045 parts record describes the bean receptacle as 8 oz. That family-level replacement part does not prove that row 171's ASIN or black variant includes the same component. It also says nothing about grounds-container capacity. The manual allows the bean and grounds receptacles and their lids to be washed in a dishwasher, while the motor housing must stay dry. Confirm the offered version and use the matched manual before relying on a strict capacity or care requirement.
Household guidance does not establish café duty
Braun labels the appliance for household use only. That is a meaningful limit for shoppers who need continuous commercial service. The reviewed sources do not establish a numeric duty interval, burr geometry or material, particle distribution, retention, noise or durability. A specialist teardown supports that the family uses a burr assembly, but does not settle those design details. The manual's espresso setting range should not be used as evidence of shot quality, and unknown workload cannot pass a high-volume threshold.
Who may find the KMM 30 useful
A home user who wants simple fineness adjustment, a cup-oriented timed routine and removable receptacles may want to compare the KMM 30 family. It is a weaker fit for anyone who requires scale dosing, numeric commercial throughput or confirmed espresso performance. Keep row 171's black finish and historical identifier separate from row 530's white title; neither is proved by the family manual. Check the actual model, parts, condition and supply label before treating a current listing as a match.
What else to compare
Before you buy
Does the KMM 30 weigh each dose?
No scale is documented; its manual describes a timer/measurer and general spoon amount.
What bean capacity is listed?
A model-matched replacement-parts record describes an 8 oz bean receptacle, not a row-ASIN match.
Does Braun give espresso settings?
The manual gives fine-grind guidance, but it is not independent espresso-performance evidence.
Can this be used commercially?
Braun's Type 3045 instructions label the appliance for household use only.
What kind of burrs does it use?
An indexed teardown supports burr construction, but the cited sources do not establish geometry or material.
Is row 171's black ASIN a verified current model?
No. The B suffix, black finish and historical ASIN remain unmapped to a current offer.
Where can I check the current price?
