How to use the mixer

Set the mixer on firm, level ground: with the drum turning, add part of the water, then gravel, cement, sand and the rest of the water, and mix 2–3 minutes until the color is even. SIMAQ has the SQREVG365LTS (1.5 sacks, Honda GX160), the SQREVG550LTS (2 sacks, Honda GX390) and the electric SQREVE-365LTS. A 1.5-sack batch yields about 0.12 m³ of concrete.

Also called: concrete mixer, cement mixer, drum mixer

The mixer blends evenly and on time; proportion and load order decide the strength of your pour. When a batch comes out wrong it's rarely the machine: it's extra water, load order or mixing time.

  1. 01

    Level and secure

    Set the mixer on firm, level ground with the brake or chocks on. Grease the marked points and check the engine oil.

  2. 02

    Start empty, add water

    With the drum turning, add part of the water first so material won't cake on the bottom.

  3. 03

    Load in order: gravel, cement, sand

    Add gravel, then cement, then sand and the rest of the water. Keep your proportion for the application and don't exceed the drum's capacity (1.5 or 2 sacks).

  4. 04

    Mix 2–3 minutes

    Let it turn to uniform color and texture. If you see lumps, give it a bit longer; leave it too long and the mix dries out and segregates.

  5. 05

    Dump fully and clean

    Dump it fully, not halfway. If you'll stop for a while, throw water and gravel into the turning drum to scour it before anything sets.

Do this

  • Stick to your mix-design proportion per application.
  • If the mix comes out dry → adjust the next batch from the design water; don't add water to the one you're about to pour.
  • Wash the drum at day's end: set concrete ruins it.
  • Load to rated capacity (sacks per batch), no more.

Avoid this

  • Don't add extra water to make it 'flow': it kills strength.
  • Never put a shovel or hand into the turning drum.
  • Don't let mixed concrete sit until it starts to set.
  • Don't run it on uneven ground: the drum spills sideways and the machine walks.

Safety

  • Gloves, glasses and boots; cement burns skin.
  • Dust mask when handling dry cement.
  • Belts and gears with their guard always in place.

Concrete mixer parts, 1.5 vs 2 sacks and loading orderSide-view diagram of a concrete mixer with six numbered parts: 1, the drum or hopper; 2, the one-piece cast-iron ring gear that turns the drum; 3, the motor, Honda or electric; 4, the anti-vibration pads under the motor; 5, the reinforced “V” chassis; 6, the grease points and gear reducer. Comparison: the 1.5-sack mixer has a 365-liter drum and a Honda GX160 or electric motor; the 2-sack mixer has 550 liters and a Honda GX390. The 1.5-sack electric mixer mixes up to 358 liters.

FAQ

What people ask about the mixer

In what order do materials go into the mixer?

With the drum turning: part of the water, gravel, cement, sand and the rest of the water. That way nothing cakes on the bottom and the cement spreads evenly.

How long should concrete mix?

2 to 3 minutes from the last material in, until color and texture are even. Less leaves lumps; much more dries the mix out.

1.5-sack or 2-sack mixer: which one?

Home builds or medium pours → 1.5 sacks (365 L). Big pours or a big crew → 2 sacks (550 L). Indoors or noise-restricted → the electric SQREVE-365LTS. The guide on choosing a concrete mixer compares them.

How much concrete per batch?

With 1.5 sacks of cement you get about 0.12 m³ per batch, depending on your mix. Use it to work out how many batches each pour needs.

What's the most common mixer mistake?

Adding extra water so the mix 'flows': the concrete loses strength. If you need better workability, adjust the mix design, not the water.

What voltage does the electric mixer use?

The advisor confirms it in your quote, along with the outlet your site needs. What the spec sheet says: a 5.5 HP motor and a 365 L drum.
