Brick and Ceramic Machine Motors

Electric motors for brick, roof tile, ceramic and concrete block production machinery are the three-phase motors turning every machine that clay from the pit, or milled ceramic raw material, passes through until it is shaped and fired. This category is about the motor fitted to those machines, not the machines themselves: what kind of load each stage puts on it, how it is chosen, and which part our range covers.

DRG Motor is a manufacturer, supplier and seller of electric motors. We do not sell machines, gearboxes, hydraulic power packs, pumps and their casings, fan impellers, inverters, extrusion dies or mill balls; our part is the standard IEC motor that drives such equipment. Models are listed on Buy Electric Motors Online.

Four production flows and where the motors sit

The sector has four flows that look alike but load the motors differently. One plant may run two of them side by side.

Clay brick

Clay is tipped into a box feeder and travels on to crushers, a stone separator and grinding rolls. In the mixer water makes it uniform, the de-airing extruder compacts it and the column leaving the die is cut by wires. Green ware goes through the dryer, then the kiln, and is stacked and packed at the exit.

Roof tile

Preparation matches brick; the clay slab from the extruder is shaped in a moulding press and travels to the dryer on trays.

Ceramic tile

Raw material is wet-ground in ball mills, the slip is stirred in tanks and turned into granulated powder in the spray dryer. A hydraulic press forms the tile, the glazing line follows the dryer, a roller kiln fires it, and on porcelain tile a squaring and edge grinding line finishes the job.

Concrete block and paver

Aggregate and cement are mixed, carried to the machine on a belt, and the vibro-press fills the mould and compacts it with vibration and pressure. Pallets go to the curing room and are then stacked. Vibration is a topic of its own: some machines use a vibration motor, others a vibrator shaft turned by a standard motor and belts.

Motor power on machines in the market

A) Values seen in maker data sheets and plant quotations (they vary by machine; the exact value is on the motor plate):

The table shows there is no single typical rating in this sector: a feeder’s apron motor is a few kW while the extruder on the same line reaches 200 kW. The plant total is not one machine’s power; each motor is chosen on its own.

B) Where DRG fits: the biggest single motor in the table is 200 kW, below our 355 kW ceiling, so each listed standard rating has a match in aluminium or cast iron. Large motors such as 200 kW 6-pole are in the range too; bigger mill and press motors and medium voltage are outside our range.

Common points in motor selection

Power, speed, mounting and environment change with the machine model. We confirm fit by comparing the old motor plate and machine documents on these points; we give no blanket fit guarantee:

• kW, speed, voltage and connection
• IEC frame, mounting arrangement, shaft end with its keyway
• flange size, pulley, coupling or gearbox interface

Clay dust, moisture and slurry

The preparation hall is full of dry clay dust; the mixer and extruder area brings water and slurry. IP55 protects against both; keep the fan cowl clean and do not let the terminal box face the wash water.

Heavy starting and shift work

A loaded mixer, extruder auger or ball mill starts under load. On larger ratings star-delta, a soft starter or an inverter is used; we do not supply drives, but our motors run on them. For long shift work, choose the rating with margin and plan the starting method together with the panel.

The DRG range: what is in, what is not

Brake motors are needed on setting and lifting gear, servo motors on robot axes, single-phase motors on small workshop machines; none of the three is in our range. A fan motor serving a kiln or dryer is mounted away from the heat, and its selection starts from the air temperature you measure there; a motor built to sit inside the firing zone is not something we produce. If the glaze room handles solvents or is classified for combustible dust, the motor must come with Ex approval papers, which our standard series lacks. For general guidance in ceramic plants see our ceramic plant motor guide; for the hydraulic side of block machines, our block machine pump motor article.

Frequently asked questions

What speed is a brick machine motor?

It depends on the machine: large roller mills and mixers often use 4 poles, some extruders 6 poles. Matching the pole count on the plate keeps pulleys and gearbox unchanged.

What matters for a ceramic factory motor near the kiln?

Tell us the air temperature at the motor position; keep the frame clear of the kiln shell so the fan can breathe.
